Bigle

Bigle, formerly Bigle Legal, combines contract lifecycle management with Libra, an AI assistant for legal departments and the business teams that work with them. The CLM covers templates, requests, negotiation, approval and electronic signature. Libra adds document questions, clause drafting, summaries and translation. A separate general chat discusses legal concepts without an open contract, while administrators can save review assistants based on their own contract playbooks.

Libra 2.0 brings AI into signature preparation and contract organization. Users can extract signers and email recipients, then check the proposed details before sending. Metadata detection identifies dates, parties and amounts, with alternative predictions available for review. Scanned contracts can be processed through an optional OCR function. The repository and workflows keep these results alongside the agreement rather than in a separate chat tool.

Bigle Iberia S.L. operates from Barcelona, with offices also listed in Madrid, London and Bogota. Named customers include Euro-Funding and Red Points. The platform uses EU hosting and its own role and group permissions. Libra is purchased separately from the CLM, with usage allowances for tokens and daily requests.

BB on AI CentralityThe models are the engine of a core capability, layered on a product that would still function without them as a document or workflow system.

AI Centrality

How much of the product is actually AI. Whether the machine learning is the mechanism the buyer is paying for or a feature layered onto conventional software, and whether the vendor is specific about which is which.

Bigle combines contract creation, collaboration, approval and signing with Libra, its legal AI assistant. The document assistant summarizes an open contract, answers questions about its clauses, drafts replacement language and translates text. General Chat handles conceptual questions without an open file. Administrators can save assistants with the company's review instructions, including a supplier risk reviewer that checks liability, renewals and jurisdiction.

Libra 2.0 adds signer and certified email recipient completion and metadata extraction from imported agreements. Those functions sit beside the template engine, repository, workflows and electronic signature product, which provide contract operations beyond the AI features.

CC on Citation Accuracy and Hallucination DisclosureAccuracy is asserted without measurement, or grounding is claimed while output cites sources the reader cannot open and verify.

Citation Accuracy and Hallucination Disclosure

Whether the vendor publishes measured accuracy on citations and assertions, grounds output to primary sources, and says plainly what its system does when it does not know. Legal has a documented public record of fabricated citations reaching filed briefs, so an untested claim of accuracy is not evidence.

The document assistant works against the contract open in the workspace, while General Chat also answers legal questions without a source file. Custom assistants can quote the original clause, explain a risk and suggest alternative wording according to an administrator's instructions. Metadata extraction presents alternative predictions for review. The product warns that answers can contain hallucinations and need checking before use.

No measured accuracy result or linked primary law retrieval method accompanies the current product. A clause quoted from a customer's agreement is a way to inspect that agreement, rather than confirmation that a legal proposition is supported by current authority.

Source: Vendor Published
BB on Autonomy and Oversight ModelA written commitment that the models work alongside a supervising lawyer, with real review surfaces, short of the full control structure: commonly the threshold at which the system stops or what happens after it is wrong.

Autonomy and Oversight Model

What the system decides on its own, what a lawyer must approve, and whether the vendor documents where the review point sits. A tool that drafts under review and a tool that files without one are different products and different risks.

Signer detection extracts names and email addresses for a user to confirm before sending. Metadata detection runs from the document panel, offers alternative predictions and saves only after the user chooses Save. Administrators configure the metadata fields and the instructions used by custom assistants. Separate workflow steps route contracts through collaboration, approval and signature, with validation groups controlling who can approve.

The terms require customers to evaluate both generated answers and extracted information before making decisions. They also prohibit AI decisions with significant legal effects on an individual. Automatic escalation after a bad prediction is not specified.

Source: Vendor Published
BB on Operational and Outcome EvidenceReal deployment evidence with substance, short of full attribution or measurement: a named customer without figures, or figures without the named customer.

Operational and Outcome Evidence

Named, dated evidence that the product works in production at real firms or legal departments. Case studies with figures and identified customers count. Unattributed testimonials and launch announcements do not.

Euro-Funding uses Bigle's CLM and Libra to address a large volume of contracts and outdated versions. Its case study describes selecting a platform, implementing it and getting staff to adopt it across a business that supports public funding, tax savings and sustainability projects. Red Points' legal director describes replacing a contract bottleneck with automation, collaboration and shared visibility. The customer catalog also covers Abertis, Aigues de Barcelona, E+H, Habitat Inmobiliaria, Forcadell and Amstro.

These are accounts of contract operations and adoption. No named customer study isolates Libra 2.0 accuracy or measures its effect with a dated before and after method.

Source: Vendor Published
BB on Privilege and Confidentiality PostureSubstantive published commitments on confidentiality and training use, short of the full picture: commonly silence on segregation between users or matters, or on what the underlying model provider may retain.

Privilege and Confidentiality Posture

How client confidences are handled: attorney client privilege and work product treatment, segregation of one client matter from another, whether client data trains any model, and what the vendor commits to in writing rather than in marketing.

Customer input and AI output remain the customer's property. The AI terms limit content use to delivering the service, with a separate exception when a user voluntarily submits feedback. Libra runs with a private model copy for customers in the European Union, and customer files are encrypted during transfer and storage. Access groups separate resources by team; administrators retain access across the workspace, while ordinary users see their own work.

These are application permissions rather than a description of how attorney client privilege is preserved. Third party model retention and privilege handling are not stated.

Source: Vendor Published
BB on UPL and Professional Responsibility PostureA real position is published on advice versus tooling, short of full treatment: commonly a disclaimer without the supervision and competence dimension, or silence on jurisdiction limits.

UPL and Professional Responsibility Posture

Whether the vendor is clear that it supplies a tool rather than legal advice, who its audience is, and how it addresses unauthorized practice of law, competence and supervision duties, and jurisdiction limits. ABA Formal Opinion 512 is the reference point. Where the advice line is not the duty a product raises, the axis is read through the nearest professional duty it does raise: judicial conduct rules and the reviewing duty for products sold only to courts, and the duty to bill for time actually spent for products that draft time entries.

General Chat explains legal concepts, compares contract types and drafts clauses, but does not replace a lawyer's professional judgment. Its examples include confidentiality agreements, good faith, force majeure and hypothetical contract scenarios. The document assistant separately limits its context to the file in use. The AI terms say output is not a substitute for professional advice and require the customer to evaluate its suitability.

They prohibit entering information about children under 14 and using AI for decisions that significantly affect an individual. No jurisdiction by jurisdiction supervision or competence framework is supplied.

Source: Vendor Published
CC on AI Governance and Bias DisclosureResponsible AI principles are published without a mechanism, a testing regime, or anything a buyer could audit.

AI Governance and Bias Disclosure

Published governance over model behavior: who owns it inside the vendor, what is tested before release, and what is disclosed about disparate output across matter types, parties, or populations.

The AI services terms describe selecting generative models trained through Constitutional AI, using stated ethical principles to shape responses and reduce subjectivity. Prohibited uses include discriminatory, deceptive and harmful activity. Administrators also configure a custom assistant's role, analysis rules and response format, so a team can apply its own contract playbook consistently. The broader information security program assigns policy approval and risk management to executive management.

That security ownership is not an AI testing program. No release evaluation, named AI governance owner or result showing uneven performance across legal tasks accompanies Libra.

Source: Vendor Published
BB on AI Safety and Data StewardshipSubstantive published policy covering most of the ground, short of the full set: commonly no named subprocessor list or no stated incident practice.

AI Safety and Data Stewardship

Retention, deletion, access control, and what happens to prompts and documents after they are processed. Whether the vendor states its subprocessors and its incident practice, or leaves the buyer to assume.

The security program includes encryption, SAML sign on, risk assessment, staff awareness and an incident reporting address. Workspace administrators create access groups and control the permissions assigned to each profile. Personal information is deleted after its purpose ends, apart from material needed for claims or legal requirements. The subscription terms separately remove stored files when the relationship ends.

In the product, users can download a chat and clear the current conversation. A named subprocessor list and a customer breach notification deadline are not supplied, and the duration of stored AI conversations is not defined.

Source: Vendor Published
CC on AI Liability and RecourseLiability is addressed only through a standard limitation clause that disclaims the exposure the product creates.

AI Liability and Recourse

What the vendor stands behind contractually when its output is wrong. Indemnities, caps, carve outs, insurance, and whether any of it is published or only reachable through a negotiated agreement.

The AI service is supplied as is, with responsibility for generated legal assessments and the use of content placed on the customer. Bigle promises reasonable efforts to reduce errors and delivery in line with industry standards, rather than a remedy for an incorrect legal conclusion. Separate support terms provide correction, repeat performance or reimbursement for defective support and limit related exposure to fees.

Those remedies concern the support service. No AI output indemnity or accuracy warranty is offered. Spanish law and the Barcelona courts govern the customer relationship where the parties may choose jurisdiction.

Source: Vendor Published
BB on Practice Systems Integration DepthReal integrations exist and are documented, short of depth: named connections without a description of what they actually move.

Practice Systems Integration Depth

How deeply the product reaches into the systems legal work already lives in: document management such as iManage and NetDocuments, Word and Outlook, contract lifecycle management, matter management, e-billing, and court filing systems.

The integrations catalog includes iManage, NetDocuments, SharePoint, Google Drive, Dropbox, HubSpot, SAP, Microsoft Dynamics, Power BI and DocuSign. A REST API handles template structures, generation from business data, file downloads, signatures and document status webhooks. A universal connector retrieves data from third party APIs to populate contract forms, while the internal repository accepts spreadsheet updates.

Microsoft Active Directory through SAML validates user access after the connection is enabled for the workspace. The named legal document system connections lack individual descriptions of synchronization direction, permission inheritance and setup. API actions have more detail than those packaged connections.

Source: Vendor Published
BB on Deployment Model and Data ResidencyDeployment model is stated clearly with partial residency detail, or residency is offered without the processing location being addressed, or the tenancy model is stated on its own with no residency detail published.

Deployment Model and Data Residency

Where the software runs and where the data sits. Multi tenant cloud, single tenant, private deployment, on premises, and whether region of residence is a published option or an enterprise conversation.

Bigle is a hosted workspace with EU servers and an EU private model copy for Libra customers. Users access contracts, shared review and signatures through the platform, and enterprise configuration includes a separate preproduction environment, custom branding and identity management. The AI can be bought independently or alongside the CLM subscription. Voice dictation is processed locally on the user's device; Bigle does not receive the audio or transcription from that function.

Cloud provider identity, individual EU regions and a separate account of where model inference runs are not specified. No customer operated deployment is described.

Source: Vendor Published
BB on Security Certifications and Trust CenterCertification is real and stated, short of accessible evidence: a named standard without scope, date, or a way to obtain the report.

Security Certifications and Trust Center

Independent attestation a buyer can pull without a sales call: SOC 2, ISO 27001, penetration test summaries, a trust center with current reports and named scope rather than a badge image.

An ISO 27001 audit is stated for Bigle's information security management system, and the security page links an SGS certificate verification entry. The certificate details could not be retrieved, so its current scope and validity period remain unconfirmed. The public security controls include AES 256 encryption, HTTPS connections, SAML sign on and regular cybersecurity audits. Its security policy assigns review and approval of the management system to executive management and extends the program to staff and suppliers.

No additional independent AI assurance is stated. The certification claim concerns information security rather than the accuracy of contract analysis.

Source: Vendor Published
CC on Model Supply Chain DisclosureThe vendor refers to advanced or proprietary models without identifying what sits underneath.

Model Supply Chain Disclosure

Which models sit underneath, whose they are, where they run, and whether the vendor commits to telling customers when that changes. A legal buyer inherits every dependency it cannot see.

Libra uses generative models for answers and drafting and discriminative models for identifying contract entities. The AI terms describe Constitutional AI as the training approach behind selected generative models, but do not identify a provider or model version. The current suite combines document chat, general chat and metadata extraction, with a private model copy for EU customers. Voice input instead relies on local device and browser processing.

The name of that browser's speech service is not fixed by Bigle. No named production model inventory or commitment to notify customers of model replacements is supplied.

Source: Vendor Published
BB on Commercial TransparencyReal pricing is published for part of the range, with enterprise tiers withheld, or the unit and structure are stated without the figure.

Commercial Transparency

Whether a buyer can learn what this costs without entering a sales process: published rates, the unit being charged, what sits behind an enterprise tier, and what implementation adds.

CLM subscriptions are organized as Starter for up to four users, Premium for five to nine and Enterprise for larger teams. Libra is contracted separately, with Basic allowing 20,000 input tokens, 2,000 output tokens and 40 daily requests, and Pro doubling each limit. Subscription scope varies with users, functionality and service level, and prices are provided during contracting. The agreement has a one year minimum term even when payments are monthly.

Template automation services are separately scoped, and some training carries an additional cost. OCR for scanned contracts requires account activation and its own pricing discussion.

Source: Vendor Published
BB on Firm and Practice CoverageSegment and practice coverage is described with substance, short of the boundaries: what is supported is clear, what is not is left open.

Firm and Practice Coverage

Who the product is actually built for. AmLaw, midlaw, small firm and solo, in house departments, government and courts, and which practice areas are supported rather than merely claimed.

Legal departments use Bigle for contract requests, drafting, negotiation, approval, signing and ongoing contract administration. Procurement, sales, HR and IT can participate in the same workflows under legal team's templates and permissions. The suite also serves law firms, with the company describing both corporate and firm customers across Europe and Latin America. Libra supports contract translation in more than 20 languages, including English, Spanish, French, German and Portuguese.

General Chat covers legal concepts beyond an individual agreement, while its document assistant stays with the open file. Supported jurisdictions and excluded practice areas are not enumerated.

Pricing

Price on request

  • The contract platform and Libra AI are separate purchases.
  • AI use is limited by daily requests and the amount of text processed.
  • The price comes through a quote, and the license has a one year minimum.
  • Template setup, some training and scanned contract reading can cost extra.

The CLM has three plans based on team size. Libra is a separate AI purchase, with a Basic allowance of 40 daily requests and a Pro allowance of 80. Input and output token limits also differ. Final charges depend on the selected software, users and support.

Implementation: Template automation is quoted from the files and instructions supplied. Advanced training and scanned contract OCR can add charges.

Confidentiality and data terms: The AI contract protects customer content, with a separate exception for voluntary feedback.

Note: No current amount is shown in the rendered pricing plans. The license commitment lasts at least one year, including arrangements paid monthly.

Legal Signals

What each signal means

A signal records what public sources say on the date shown. It is not a grade and it is not a recommendation. Where a signal reads Not addressed, it means the index did not locate the material in public sources on that date, which is a statement about disclosure rather than about the product.

Confidentiality and Privilege

Client Data in Training

Can material a lawyer puts into this product be used to train a model?

Opt in

Training occurs only where the customer has affirmatively enabled it.

Section 32.3 limits customer content to providing the AI service and bars its use to develop or improve that service. A user who voluntarily supplies feedback creates an exception for maintaining and improving it. The input and resulting output remain the customer's property. Libra's private EU model environment also keeps data from feeding a model beyond that user's platform. The agreement does not describe what content accompanies feedback.

Prompt and Output Retention

How long does the product keep what a lawyer typed, and can that be set to zero?

Disclosed without a period

Retention is acknowledged in public materials with no stated period.

Chat history can be downloaded and the current conversation cleared. Saved metadata stays in the contract database and remains editable. Subscription termination removes material from the customer's private area, while the privacy policy retains information needed for legal obligations or claims after other processing ends. None of these provisions gives an active account's prompt and response retention period, and clearing a chat is not described as a zero retention setting.

Ethical Walls and Matter Segregation

Does retrieval respect the firm’s ethical walls, or can the model read across them?

Own model, documented

The product maintains its own permission model, documented, requiring the firm to keep it aligned.

Access groups define which departments or teams can see a resource. A new contract belongs to its creator's group by default, and an administrator can change its group and the groups a user may access. Profiles separately govern actions: administrators see the entire workspace, supervisors see their group's work and creators see their own. Template access can also be restricted. No retrieval connection that inherits an outside document system's permissions is described.

Third Party Request and Subpoena Notice

If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?

Disclosure addressed, notice absent

Published terms or policy address disclosure to authorities or in response to legal process, and no commitment or reservation regarding customer notice is located anywhere. The vendor has told the customer that data can leave and has said nothing about whether the customer hears of it.

The privacy policy permits disclosure to third parties when a legal obligation requires it. It offers individuals access, correction, deletion and processing restriction rights, with requests directed to Bigle's legal contact. The AI service terms protect content ownership and restrict use to the service, subject to voluntary feedback. No promise tells a customer before disclosure to an authority, and no transparency report describes requests received.

Accuracy and Authority

Primary Law Corpus Provenance

Where does the law in this product come from, and does the vendor have the right to use it?

Not addressed

No located public material identifies the corpus behind the product’s answers.

Document Assistant answers from the agreement currently open, and company playbooks can direct the clauses it examines. General Chat also explains legal principles and explores hypothetical scenarios without that file context. Its underlying legal knowledge is not tied to a named collection of cases or statutes, a license or an update timetable. Contract metadata includes applicable law, which is extracted contract information rather than a maintained legal research source.

Source: Operator VerifiedAs of Oct 15, 2026Evidence

Good Law Verification

Does the product tell you when the authority it just cited has been overruled?

Not addressed

No located public material addresses whether authority is checked for subsequent history.

Libra can explain clauses and draft alternatives in the language of a contract. Its legal discussion covers principles such as good faith and force majeure, and the assistant warns users to validate generated answers. It does not describe a citator, subsequent case history or an inline warning that an authority has been overturned. Extracting an applicable law field from an agreement does not perform that check.

Source: Operator VerifiedAs of Oct 15, 2026Evidence

Refusal and Uncertainty Behavior

What does the product do when the answer is not in the corpus?

Not addressed

No located public material addresses what the product does when it cannot ground an answer.

A custom risk assistant can be instructed to say when it finds no risk in the specific categories its administrator selected. That is a configurable review instruction. Neither the general chat nor the document assistant has a stated refusal path for an unsupported legal answer. Metadata review exposes other predictions, but no confidence measure or abstention threshold is described for the generated text.

Fabricated Citation Record

Does a public court record exist addressing fabricated or hallucinated legal citations in output from this product?

None located

No court order, opinion or disciplinary record addressing fabricated or hallucinated legal citations produced by this product has been located as of the date shown. This is a statement about the public record on that one subject, not a finding about the product, and this signal is not a litigation history.

Damien Charlotin's AI Hallucination Cases database has no entry naming Bigle or Bigle Libra as the source of fabricated citations. Libra's current products cover contract drafting, questions and metadata extraction, with a separate general legal chat. The help center warns that answers can contain errors and tells users to review them before applying them to their work.

Professional Responsibility

Bar Guidance Alignment

Has the vendor engaged in public with the ethics opinions its buyers are bound by?

Not addressed

No located public material engages with bar or ethics guidance.

The General Chat guide preserves the lawyer's professional judgment, and the AI agreement requires review before relying on an answer. Usage restrictions cover harmful decisions about individuals, deceptive use and information about young children. These are product rules rather than engagement with a named bar opinion. No mapping to lawyers' competence, confidentiality or client consent guidance from a professional body accompanies the service.

Source: Operator VerifiedAs of Oct 15, 2026Evidence

Billing and Fee Posture

Does the vendor address what happens to the bill when the work takes an hour instead of six?

Savings claims only

Public materials claim time savings without addressing billing or disclosure, and the product sits inside a fee relationship between a lawyer and a client where those savings would change the bill.

Bigle sells contract automation to corporate teams and law firms and promotes less manual drafting, copying and administrative work. Its customer catalog includes Amstro's legal and business process services alongside corporate legal departments. Libra's new signer and metadata functions further reduce routine entry work. No guidance describes how a law firm should bill for that saved time or disclose AI assistance to the client paying for the contract work.

Source: Vendor PublishedAs of Oct 15, 2026Evidence

Outside Counsel Guideline Readiness

Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?

Not addressed

No located public material supports a client side disclosure obligation.

The public materials include a security overview, information security policy, customer terms and a certificate verification link. They describe permissions, encryption and EU hosting, but do not identify the model providers or other processors handling a client's contract text. No consent or disclosure pack for a law firm's clients is supplied. Bigle Academy provides product training and a knowledge base for customers rather than an outside counsel AI disclosure package.

Source: Operator VerifiedAs of Oct 15, 2026Evidence

Court Disclosure Support

If a judge’s standing order requires an AI disclosure, can the product produce one?

Partial record

Some elements of the record are available, short of a document level export.

A user can export the entire conversation with the document assistant, preserving the questions and answers. Contract negotiation also keeps tracked changes and versions, while electronic signatures generate evidence about the signing transaction. These are different records serving different stages of the workflow. No export connects a generated passage to the model version, retrieved legal authorities and named human verifier for a filing certification.
