Zuva

Zuva is contract analysis AI from the team that built Kira Systems. When Kira was sold to Litera in 2021, its founders kept a copy of the underlying AI and about 30 of its staff, and that became Zuva Inc., an Ontario corporation. Zuva sells its technology three ways. Zuva Analyze is a self serve review tool for legal teams and in house lawyers that extracts more than 1,400 pretrained fields and exports to Excel or Word.

The Zuva API gives developers the same extraction, classification and custom field training, and Microsoft's legal team has used it inside Power Automate. Diligence Reviews pair the AI with former large firm M&A lawyers to produce sell side diligence and disclosure schedules. The core fields are purpose trained machine learning built since 2011, with generative AI added for answers and summaries. The service runs on Microsoft Azure in the United States or Europe, and Zuva states SOC 2 Type II certification.

Under the Kira sale, Zuva says it will not sell interface based contract analysis directly to law firms until later in 2026.

Capability grades

All 15 axes, graded from public sources on the date shown. Hover a grade to see what the letter means on that axis.

AA on AI CentralityThe artificial intelligence is the product. Remove the models and there is nothing left to sell.

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.

Machine learning is the product in every form Zuva sells. The API is a REST service for extracting structured data from contracts and classifying documents, and Zuva Analyze puts the same extraction behind a self serve interface. Diligence Reviews, the third offer, are sold as AI assisted contract analysis with lawyer review, so even the service is built on the extraction. The models come from Kira Systems, and generative AI now adds answers and summaries in Analyze.

Remove the models and nothing is left: there is no document management, workflow or storage product underneath. The security overview says the API is not meant as a long term repository.

BB on Citation Accuracy and Hallucination DisclosureGrounding is real and documented, with linked primary sources and a described retrieval method, short of published accuracy figures an outsider can test.

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 output is the contract's own text and the method is described, and no accuracy figure is published. The extraction documentation describes each result as an instance of the requested text in the document, so a reader checks a finding against the clause it came from. The API page contrasts the fields with general purpose language models: the same input gives the same extraction every time. No recall, precision or error rate is published for the fields.

The Analyze page says other systems give maybe 70 to 80 percent accurate results and that internal testing found faster review with comparable accuracy, but it gives no test set or figure. Analyze's generative summaries are not described at all.

Source: Vendor Published
CC on Autonomy and Oversight ModelAutonomy is claimed and oversight is asserted without a mechanism. Human in the loop appears as a phrase rather than a described control.

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.

Human review is named for the service and not described for Analyze or the API. The Diligence Reviews pricing page lists review by former large firm M&A lawyers as part of every engagement. No page says what the reviewers check, how much of each document they read, or how an extraction they reject is handled. Zuva Analyze is described in three steps, upload, extract and export, with nothing on who reviews the export or what a user should verify.

The API leaves oversight entirely to the developer building on it. The product is extractive rather than agentic: it returns text found in the document and does not draft, send or decide anything. A missed provision produces no output to review, and nothing published says how the service or the software guards against that.

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.

One named customer is published with a figure, without a date or method, and the rest of the evidence belongs to the earlier company. The API page says Microsoft's legal team used Zuva inside Power Automate and reports a reduction of roughly 75 percent in time spent on routine contract requests, with a target of going from a three day service level to about three minutes. No date, period, volume or method stands behind the figure, and the target is stated alongside the result.

The Analyze page features a case study of an in house lawyer at a global motorsports company and reports internal testing of 40 to 80 seconds a page against about three minutes manually. The claim that 18 of the world's top 25 M&A law firms used the same technology describes Kira Systems at its sale, not Zuva's customers.

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.

Confidentiality, ownership and segregation are in writing, and training and privilege are addressed only in part. Under the license terms the customer owns its documents, customer data and outputs (section 6), and Zuva treats them as confidential information held to at least a commercially reasonable standard of care (section 8). Section 2(g) confines Zuva's improvement right to usage data, defined as information about access to and use of the service.

The security overview says model storage does not rely on the content of the documents used to train custom fields, and only the creating token can reach an account's data. No express training prohibition appears in the agreement. Nothing treats privilege or work product, and nothing covers what the generative AI provider behind Analyze summaries may keep.

Source: Vendor Published
CC on UPL and Professional Responsibility PostureA boilerplate disclaimer sits in the terms while the marketing describes the product in advice terms, or the intended audience is left ambiguous.

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.

The review service is sold as a substitute for law firm work to buyers who are not all lawyers, with only a standard disclaimer in the terms. The home page and the review service's pricing page offer sell side diligence and disclosure schedules with lawyer review, to buyers including chief financial officers and private equity firms. No page states whether that work is legal advice, whether Zuva is a law firm, whether a lawyer and client relationship arises, or who is responsible for the disclosure schedule a seller signs.

The accuracy disclaimer in the license terms limits output rather than drawing the advice line. Analyze is addressed to legal teams and the API to developers, and neither says where its output stops and a lawyer's judgment begins.

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.

Parts of how the models are built are disclosed, and no governance framework, owner or testing result is published. The source of the training data is stated, and the Analyze page describes the fields as pretrained and tested. The science page lists about ten research papers by Zuva's research team on document review, interpretability and how lawyers work with AI, published on the principle that research advances through free dissemination.

The governance layer itself is missing. There is no responsible AI policy and no named person accountable for model behavior. Nothing describes what is tested before a field or model is released, and nothing reports how extraction quality varies across document types, languages or drafting styles.

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.

Retention, deletion, encryption and segregation are published specifically, and subprocessors and incident practice are not. The customer sets how long uploads stay and can delete them early, access to each account's data is limited by token, and the security overview describes encryption in transit and at rest. Section 8(d) of the license terms commits Zuva to physical, managerial and technical safeguards and refers to a separate data protection addendum.

No named subprocessor list is published, and no incident notification period is stated. The privacy policy covers registration and site tracking and does not address uploaded documents.

Source: Vendor Published
BB on AI Liability and RecourseA real published position on liability, short of the full picture: commonly a stated indemnity without scope or caps.

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 license terms publish a cap, carve outs and an intellectual property indemnity, and disclaim the accuracy of results. The DocAI and AI Trainer License Terms and Conditions, last updated 11 May 2022, are governed by Ontario law. Section 7(a) commits Zuva to indemnify the customer against third party claims that the services, used as the agreement allows, infringe intellectual property rights. Section 10 caps each party's liability at the amount paid in the six months before the claim, and carves fraud, willful misconduct and intellectual property infringement out of the cap.

Section 9(b) disclaims all other representations and warranties, including any warranty that results will be accurate or reliable. These terms cover the API and the software. The Diligence Reviews pages publish no engagement terms, so nothing says what Zuva stands behind when a disclosure schedule prepared with its lawyers is wrong.

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 API is documented for developers, with one named connector into a workflow system and none into document management. The documentation covers file submission, OCR, classification, language detection, field extraction and custom field training, with a quick start, a Python SDK tutorial and a public API reference among the guides. A tutorial covers the Zuva Power Automate connector. That is enough for an engineer to build the extraction into another system.

Analyze exports results to Excel or Word for analysis across documents. No connector to a document management system such as iManage or NetDocuments, a CLM or a matter management system is published. Nothing describes what a Power Automate flow moves back beyond the extraction results, so integration depth depends on engineering by the customer.

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.

Deployment options and regions are published, and the processing location of the generative features is not. The API servers run on Microsoft Azure in the United States and Europe, according to the security overview. The API is also available in a private cloud, including a different Azure region, or for self hosting on Azure or AWS for an added fee. The license terms place hosting, in section 2(d), in the jurisdiction the customer selects and user authentication in Canada or the European Union, and the FAQ confirms hosting on the Zuva cloud or on premises.

For extraction, storage and processing locations are clear across the shared cloud, a private cloud and the customer's own infrastructure. Nothing states where the generative AI behind Analyze answers and summaries runs, or whether it stays within the selected region.

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.

SOC 2 Type II is stated across the site, and no report, auditor or period can be reached. The home page, the privacy policy footer and the API security overview all state the certification, and the overview's SOC2 compliance section says the Zuva API has obtained it. No auditor, report period, scope statement or route to request the report appears on those pages, the Analyze page or the documentation index, and no trust portal is linked.

The overview does describe controls in some detail: TLS 1.2 in transit, 256 bit encrypted storage, disaster recovery, security testing and response, and personnel security, under named information security policies.

Source: Vendor Published
BB on Model Supply Chain DisclosureThe supply chain is partly disclosed: providers named without change notification, or architecture described without the providers.

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.

The extraction models are described, and the provider behind the generative layer is not named. The about page says Zuva's AI is the technology developed at Kira Systems since 2011 and retained at the sale. Its research team works on the underlying models and on wrappers around general purpose AI. The Analyze page calls the fields purpose trained machine learning enhanced with generative AI for structured answers and summaries.

Custom fields are trained on the customer's own documents, and the extraction models run on Azure in the region the customer selects. Nothing names the provider or model producing the generative answers and summaries, where it runs, or what that provider keeps. No commitment to tell customers when a model or provider changes is published.

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.

Rates and units are published for the self serve products and the review service, while enterprise and hosting terms are withheld. The pricing structure charges Analyze by the document, charges the API by the document and by the field after a free tier, and sets Diligence Reviews in fixed fee bands with stated turnaround times. Enterprise volume, private cloud, self hosting and rush delivery are left unpriced. From the published figures, the cost of a review project, a batch of contracts or an integration can be worked out without contacting Zuva.

AA on Firm and Practice CoverageWho the product serves is documented precisely: firm segments, in house and government use, and the practice areas actually supported, with the limits stated.

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.

Who each offer serves is stated, and so are the limits. Diligence Reviews are for the sell side of M&A, covering pre screens, disclosure schedules and execution status, for buyers such as chief financial officers, private equity firms selling portfolio companies and M&A advisors. Zuva Analyze is for legal teams and in house lawyers working on M&A, contract portfolio management and compliance. The API is for developers building contract automation into their own products.

The field library covers more than 1,400 provisions and more than 225 document types. Two boundaries are published. Under the Kira sale, Zuva agreed not to sell interface based contract analysis directly to law firms until later in 2026. And the out of the box fields were trained on publicly available English documents. Nothing states which governing laws or contract types beyond that population the fields have been tested on.

Pricing

$10 per documentUSD, as published, never converted

  • Zuva charges by the document.
  • Its review tool costs $10 for each contract, with at least $5,000 spent.
  • Developers can use the API free for small amounts, then pay per document.
  • A full sale diligence review by Zuva's lawyers costs $10,000 to $75,000 for most deals.
  • Big company plans and private hosting are priced on request.

Zuva Analyze, the self serve review tool for legal teams, costs $10 a document pay as you go, with a $5,000 minimum commitment, five documents free to try and enterprise volume pricing on request. The Zuva API has a free tier of 25 daily files, classifications, language detections and extraction requests, with up to ten fields per request. Beyond that it charges $1.25 a document plus $0.0015 per field per page, with a $5,000 minimum and bulk discounts, and an enterprise tier at custom pricing with service levels.

Diligence Reviews are mostly fixed fee: $10,000 to $75,000 for about three quarters of deals and $125,000 or more for large or complex scopes. They take one to two weeks, with rush delivery at extra cost.

Implementation: None stated for the cloud products. Private cloud and self hosting are offered for an additional fee that is not priced.

Confidentiality and data terms: Not applicable. A separate data protection addendum is referred to in the terms and is not published.

Note: The $5,000 minimum applies to both pay as you go plans. Enterprise volume rates, private cloud and self hosting fees, and the rush premium for reviews are not published. The $10 figure is Analyze, the product a legal team buys; the API's per document rate is lower and adds per field charges.

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?

Never, in policy only

A public policy or trust page states no training on customer content, with no matching term located in the published agreement.

A public vendor page says neither Zuva nor any other customer may use a customer's fields and data without permission, and the agreement does not address training. The API security overview states the commitment, and the standard fields were trained on public filings. The license terms (11 May 2022) never name training; the only reuse right they give Zuva covers usage data about access to the service, so the commitment is a policy rather than a contract term.

Prompt and Output Retention

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

Customer set, zero available

The customer sets the retention window and no retention is an available setting.

The customer sets retention, and keeping nothing is offered. The API page says retention can be none, a week or whatever the customer needs; the security overview says uploaded documents expire after seven days by default, that the expiry can be set from one hour to fourteen days, and that files can be deleted earlier through the Files API without restoration. The Analyze page says documents are deleted when the customer chooses.

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.

Zuva documents its own access model at the level of the API token. The security overview says all data in an API client account is stored and permissioned so that only the token that created it can access it. Other customers and Zuva itself are barred from using a customer's data without consent. Nothing describes walls between matters inside a customer or any link to document management permissions.

The license terms commit to prompt written notice of a compelled disclosure where the law permits. Section 8(c) covers subpoenas, civil investigative demands and requests in legal proceedings for confidential information, which includes the customer's documents and data, and requires reasonable efforts to preserve confidentiality and cooperation with a protective order. No transparency report was located.

Sources named, basis unstated

Sources are identified without stating the license or rights basis.

The collection behind the models is named; the product itself works on contracts the customer supplies rather than on primary law. The API FAQ says Zuva's legal knowledge engineers train the fields on publicly available documents such as EDGAR filings, all in English.

Refusal and Uncertainty Behavior

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

Documented

The vendor describes refusal or abstention behavior in public materials.

The extraction returns nothing for a field it does not find. The field extraction documentation says each requested field comes back with zero or more extractions, each an instance of the text in the document. No confidence score is described, and the generative summaries in Analyze carry no published abstention behavior.

Billing and Fee Posture

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

Outside the fee relationship

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.

The products are bought by in house legal teams, developers and companies selling a business, none of which bills a client for the work, and under the Kira sale the interface products are not yet sold to law firms. The review service is marketed at about 80 percent below traditional law firm costs on a mostly fixed fee with no hourly billing, a saving aimed at the buyer's own cost.
