Contract Logix
Contract Logix is contract lifecycle management software for legal, procurement, finance and sales teams, covering requests, authoring, negotiation, signature, a central repository and tracking of obligations and renewals. Its AI works on both sides of signature. The Contract Intelligence Engine reads signed contracts and extracts key terms as data, with a published accuracy of about 95 percent on standard fields, rising to about 99 percent with human review.
Contract Logix Review gives first pass redlines against a company's own standards inside Word or Google Docs. The company reports more than 60,000 users. Contract Logix, LLC is based in Lowell, Massachusetts, and was acquired by LegalSifter on 22 October 2024. It still sells under its own name, with its own agreement.

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.
Contract Logix's AI drives two named features on a platform that works without them. The Contract Intelligence Engine works after signature: AI Contract Analysis detects which key terms and clauses a contract contains, and AI Data Extraction (AIDE) pulls chosen terms into the platform as data. It offers 92 standard fields, custom fields driven by extraction prompts, line item detail through Custom Data Objects, and reprocessing of a whole portfolio against a new setup without reloading documents.
Contract Logix Review works before signature, giving first pass redlines against the company's own standards in Word or Google Docs. Underneath is a full contract lifecycle platform: intake, authoring, negotiation workflow, repository, permissions and tracking of obligations, renewals and milestones, all of which the company sold before the AI existed.
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.
An accuracy figure is stated, along with the gain from human review. AIDE is stated to reach about 95 percent or better on standard extraction fields, rising to about 99 percent with human validation. That tells a buyer the system is wrong on roughly one field in twenty unaided. What is missing: no test set, document count, field types or languages are described, no failure modes are named, and the words about and roughly cannot be tested.
No independent validation exists. The product extracts from the customer's own contracts and cites no outside authority, so fabricated sources are not the risk here.
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.
Contract Logix quantifies its human review step. Its accuracy claim is about 95 percent or better unaided, rising to about 99 percent with human validation, which tells a buyer what skipping review costs. Review's output is described as first pass redlines, which sets the expectation that a person finishes the work. What is missing: no threshold at which the system defers or escalates, no confidence signal on an individual extraction, no list of fields or clauses it will not attempt, and nothing on what happens after an extraction is found wrong beyond reprocessing a portfolio.
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.
Scale comes with one measured example. More than 60,000 legal, procurement, finance and sales professionals use the platform across hundreds of brands. The Director of Contracts at Soar Technology says a question that took three days now takes five minutes, which joins a named customer, a role and a figure. What is missing: it is a single example, it is not dated, and no method explains what the question was or how the old process worked.
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.
Contract Logix publishes detailed access and data handling practices and says nothing about privilege. Its security page describes role and feature based permissions set by the customer, a customer System Owner who invites users, email validation, configurable passwords and SAML 2.0 single sign on. Staff undergo background screening and regular privacy and security training. Deletion and archiving follow the customer's policies, with restore limited by role.
The privacy policy covers the services as well as the websites. What is missing: privilege and work product are not addressed, no AI model provider is identified, and the confidentiality terms sit in an unpublished customer agreement.
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.
Nothing published draws the advice line, for a product that produces legal work and is sold to people who are not lawyers. The audience includes procurement, finance and sales, with pages by department, role and process. Review produces first pass redlines, and the Intelligence Engine identifies terms and clauses in signed contracts. Nothing says whether that output is legal advice, whether a lawyer should review a redline before it goes to a counterparty, what a procurement or finance user may rely on, or who is accountable when a governing law or indemnity clause is misread.
The vendor addresses lawyers directly, with a Legal Department page and pages for General Counsel, Paralegal and Compliance Officer, so the audience is clear and the professional line is what is missing. No supervision statement or jurisdiction limit is published.
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.
Nothing published on AI governance is published. The navigation and footer, covering platform, product, security, privacy, hosting, integration, solution, company, news and blog pages, contain no responsible AI page, AI policy, principles, acceptable use position or governance section. No framework such as NIST or ISO 42001, no accountable owner, no testing regime and no evaluation result beyond the headline accuracy figures is published, and bias is not addressed.
The site documents security and privacy carefully but not model governance. That matters because extractions feed the obligation and renewal tracking the platform is bought for, so uneven model behavior across contract types or languages would flow silently into the record.
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.
Most of the ground is covered, with subprocessors and incident practice missing. Deletion and archiving follow the customer's own policies, supported by application and service controls, and only users with the right role can restore data. Access control is strongest: role and feature based permissions set by the customer, a designated System Owner, email validation of every user, configurable password policy, and SAML 2.0 single sign on with Azure Active Directory, ADFS, DUO, Okta and Ping.
Staff undergo background screening and regular privacy, security and regulatory training, including HIPAA. Hosting on Microsoft Azure has its own page. What is missing: no subprocessor list (the privacy policy mentions service providers that may be outside the United States without naming any), no breach notice practice, and no retention period for prompts or extraction outputs.
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.
No published position on liability for AI output is published, because the customer agreement is not published. The footer terms govern website use, and their entire agreement clause carves out any separately executed customer agreement. So a customer agreement exists, and a buyer cannot read its risk allocation before a sales process. No warranty on extraction output, liability cap, indemnity, service level, uptime commitment or insurance position is published, though the vendor's own 95 percent accuracy figure admits a material error rate.
Nothing says who bears the loss when a wrong renewal date or liability cap flows into obligation tracking. The website terms set Massachusetts law, non exclusive.
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.
Integrations meet the work where it happens. Review delivers its redlines inside Microsoft Word or Google Docs, so negotiators stay in the drafting tool. Single sign on runs over SAML 2.0 with Azure Active Directory, ADFS, DUO, Okta and Ping. An Integrations page exists, and Azure hosting has its own page. What is missing is depth: what each connection moves, in which direction, and what setup it needs. No practice, document or matter management, e-signature, ERP or procurement system is named on the pages read, which matters because procurement and finance are buyer groups. The Integrations page was not opened.
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.
Microsoft Azure is the named host, with a dedicated page, and the security page describes Azure supported controls. That says whose data centers are used, not where a customer's contracts sit. No data center location, country, region or regional choice is stated. The privacy policy says service providers may be outside the United States, without naming them or the countries. Nothing states whether a customer's repository is shared or isolated, no single tenant, private cloud or on premises option is offered or refused, and nothing says where the extraction models run. A buyer with data location rules should ask where its contracts are stored and processed.
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.
No independent security attestation is published. No SOC 1, SOC 2, ISO 27001 or similar certification, penetration test summary, third party assessment or trust center was found. The security page describes the vendor's own controls, from permissions and single sign on to staff screening, HIPAA training, customer set deletion and Azure hosting, but these are the vendor's statements, not a third party's check. The privacy policy claims certification under the EU-U.S. Data Privacy Framework, the UK Extension and the Swiss-U.S. framework, with BBB National Programs for recourse.
That framework is self certification, not an audit, and the participant record could not be confirmed, so it is noted and not relied on.
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.
Nothing published describes the model supply chain. The product pages detail what the AI does, from 92 extraction fields to reprocessing and accuracy, and say nothing about what performs it: no model, version, provider, or split between own and third party models, and nothing on whether Review and extraction share models. Microsoft Azure is named as host and Azure Active Directory for sign on, which is infrastructure rather than a model disclosure, and does not say whether Azure OpenAI, another API or an in house model reads contracts. Nothing covers what a provider may keep of a document sent for extraction, and no change notice is promised.
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.
No pricing is published at any level, including the unit of charge. There is no pricing page; the site offers a demo request. No rate, per seat figure, minimum, term or implementation charge appears, and the website terms do not cover subscriptions, which sit in the unpublished customer agreement. A buyer cannot tell whether pricing is per user, per contract, by tier or by volume. Third party listings describe pricing by user count, contract volume and feature tier, with Submitter, Read Only and Full User levels and separate implementation fees; these are not the vendor's own and are not relied on. One listing gives the starting price as contact vendor.
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.
Segments are described in detail, with the boundaries left open. A Legal Department page names General Counsel, Paralegal and Compliance Officer, each with its own page, alongside a Corporate Counsel's Guide to contract lifecycle management. Solution pages also cover industries (including healthcare, manufacturing, pharmaceutical and energy), departments, roles, processes and company sizes. More than 60,000 professionals across hundreds of brands use it.
What is missing: no contract types are named as handled well or poorly, the 92 standard fields are counted but not listed, no languages are stated, and no company size range is given. Legal is one of four buyer groups, with procurement, finance and sales.

Legal Signals
What each signal meansA 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.
Client Data in Training
Can material a lawyer puts into this product be used to train a model?
The customer agreement or data processing addendum contractually limits use of Customer Data to providing the contracted service, and no surface names training either way. The limit is bound, which a policy page is not, but it is not an express training prohibition. If any surface names training in either direction, one of the other values is true and this one is not.
The privacy policy, which covers the services as well as the websites, limits processing to the purposes for which data was collected or later authorized. Sensitive information needs an opt in before disclosure to a third party or any new use, and onward transfers to service providers carry continuing responsibility. Nothing in it permits or prohibits using customer content to train, fine tune or improve models, so the buyer has a purpose limit that would not obviously allow training and no express confirmation.
This is a policy, not a contract term, because the customer agreement is not published. No model provider is named, so nothing says what a third party may do with a document sent for extraction.
Prompt and Output Retention
How long does the product keep what a lawyer typed, and can that be set to zero?
The customer controls the retention window, by product configuration or by contractual instruction, but zero retention is not stated as available.
Contract Logix puts retention in the customer's hands. Its security page says application and service controls support the customer's own deletion and archiving policies, and that the customer sets its own requirements; only users with the right role can restore data. A buyer with a records schedule can apply it here. Three limits: no default is stated for customers who configure nothing, no maximum is committed, and nothing says whether prompts, extraction candidates or prior extraction results are kept separately from the contracts. No deletion on termination commitment was located; that would sit in the unpublished customer agreement.
Ethical Walls and Matter Segregation
Does retrieval respect the firm’s ethical walls, or can the model read across them?
The product maintains its own permission model, documented, requiring the firm to keep it aligned.
A documented permission model gives an administrator something to plan against. Role based and feature based permissions are set by the customer's administrator, with multiple user types and roles that can be added or removed. A customer System Owner invites users and grants access in the application. Every user is validated by email, passwords follow a customer set policy, and single sign on runs over SAML 2.0 with Azure Active Directory, ADFS, DUO, Okta and Ping.
Restore rights follow the same roles. What is missing: no walls between matters, clients or counterparties are described, and nothing says whether a boundary can hide content rather than only block it. The product centers on a company's own contracts, so this matters less than on a law firm tool.
Third Party Request and Subpoena Notice
If someone subpoenas the vendor for a firm’s data, does the firm hear about it first?
No located term or policy addresses third party requests for customer data.
Nothing published addresses third party demands for customer data: no notice to the customer of a subpoena, warrant or regulatory demand, no chance to object, no commitment to narrow or challenge, no transparency report and no law enforcement page. The privacy policy notes the vendor is subject to FTC oversight for its Data Privacy Framework commitments, which concerns the vendor's own regulation, not notice to customers.
The repository holds a company's signed agreements, which litigants and regulators seek. The customer agreement, where a notice clause would usually sit, is not published. The pages read were the privacy policy, the website terms, the security page and the platform pages.
Primary Law Corpus Provenance
Where does the law in this product come from, and does the vendor have the right to use it?
No located public material identifies the corpus behind the product’s answers.
Contract Logix answers from no body of law. The Intelligence Engine reads the customer's own contracts, and Review works against the company's own standard positions, so there is no licensed legal corpus to test. What is not addressed is what the extraction models learned from. The 92 standard fields and their accuracy figure imply models trained or tuned on a body of contracts, and nothing says whether that was public filings, licensed data, synthetic data or other customers' agreements.
Nothing excludes the last. No model provider is named. The pages read were the Intelligence Engine page, the Review page, the security page, the privacy policy and the website terms.
Good Law Verification
Does the product tell you when the authority it just cited has been overruled?
No located public material addresses whether authority is checked for subsequent history.
The question does not arise: the platform cites no law. The AI reads a company's own contracts and standard positions, and no case, statute or regulation is cited to the user. The nearest issue is whether extracted terms stay current. Nothing published says how the system detects that an amendment, side letter or novation changed a term already extracted, or what happens to tracked obligations when a clause is renegotiated.
Portfolio reprocessing handles changes to the extraction setup, not to the contracts. The pages read were the Intelligence Engine page, the Review page, the platform pages, the security page and the privacy policy.
Refusal and Uncertainty Behavior
What does the product do when the answer is not in the corpus?
No located public material addresses what the product does when it cannot ground an answer.
Nothing published describes what the system does when it cannot answer reliably. The vendor's accuracy claim, about 95 percent unaided and about 99 percent with human review, admits roughly one field in twenty is wrong unaided. Nothing says that a low confidence extraction is flagged, that a missing field is returned as absent rather than a near match, that extractions carry confidence scores, or that any field type is excluded.
Nothing says what Review does when a clause has no match in the company's standards. Because extractions feed obligation and renewal tracking, a silent error becomes a missed renewal. The pages read were the Intelligence Engine page, the Review page, the platform pages, the security page and the privacy policy.
Fabricated Citation Record
Does a public court record exist addressing fabricated or hallucinated legal citations in output from this product?
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.
Searched on 13 September 2026 on the company name and both AI product names across reporting and trackers of court decisions on AI fabricated citations. None located. No decision, sanction or referral names Contract Logix, the Contract Intelligence Engine or Contract Logix Review. Reported cases, including sanctions in Wyoming, Indiana, California, Mississippi and Kentucky and a show cause order in a Kansas patent case, involve general purpose assistants, not contract platforms. Neither AI feature cites legal authority, so the exposure is structurally low.
Bar Guidance Alignment
Has the vendor engaged in public with the ethics opinions its buyers are bound by?
No located public material engages with bar or ethics guidance.
No bar or ethics guidance is engaged, and customers are not asked to use the product in line with professional duties. That stands out because Contract Logix addresses lawyers directly, with a Legal Department page, pages for General Counsel, Paralegal and Compliance Officer, and a Corporate Counsel's Guide, yet says nothing about the professional line in a tool that drafts redlines and extracts governing law and indemnity terms.
Its regulatory statements cover data protection: GDPR, CCPA, the Data Privacy Framework and HIPAA training for staff. Those bind the vendor as a processor, not the customer as a lawyer.
Billing and Fee Posture
Does the vendor address what happens to the bill when the work takes an hour instead of six?
The product does not touch a fee between a lawyer and a client. It operates before an engagement exists, or it is bought by a team that bills no client for the work. Savings claims aimed at the buyer’s own cost are recorded in the summary and do not make the row a savings claim, because no client bill is in the loop.
Contract Logix sits outside the lawyer client fee relationship. The buyer is an organization managing its own contracts, through its legal, procurement, finance and sales teams, and the legal seats named are in house roles. There is no client bill on which AI savings could be passed on or disclosed. Nothing stops a law firm from buying it for its own matters, and such a firm would find nothing on marking AI assisted work for fee purposes.
The published savings claim, a three day question answered in five minutes for a Director of Contracts, measures internal effort, not billed time.
Outside Counsel Guideline Readiness
Can a firm get this vendor through a client’s AI clause without a bespoke negotiation?
No located public material supports a client side disclosure obligation.
None of the three things a firm would need is published. The privacy policy mentions service providers that may be outside the United States and names none, so there is no subprocessor list. No model or provider is named, so a customer cannot tell a client which third party reads its contracts. There is no data processing addendum, standard contractual clauses, consent template or questionnaire response to forward. The customer agreement that would usually carry these is not published.
Microsoft Azure as host and the single sign on providers are not AI subprocessor disclosures. The Data Privacy Framework claim is a transfer mechanism, not a disclosure document.
Court Disclosure Support
If a judge’s standing order requires an AI disclosure, can the product produce one?
No located public material addresses court disclosure or verification certification.
Nothing published addresses disclosing AI involvement. Nothing marks an extracted field as machine generated, shows the origin of a Review redline, or keeps a record of AI use in exports or reports. No audit trail, certification template or disclosure guidance was located. The likely audience is a counterparty in a dispute, an auditor or a regulator rather than a judge, and each would want to know which terms in the contract record a machine read.
With a published unaided accuracy of about 95 percent, that matters. Role based restore and administrator controls are access governance, not provenance. The pages read were the Intelligence Engine page, the Review page, the security page, the privacy policy and the website terms.
