Lexi

Every part of the workspace is model work, sold as AI associates. Client onboarding reads emails, meeting notes and documents and assembles them into organized case files. Drafting produces letters, motions and contracts in the firm's voice, contract review flags risk, and tabular review answers the same questions across hundreds of documents at once.

Research returns precedents, statutes and case law with citations, chronologies build timelines from documents, and translation covers more than 100 languages. The assistant learns each account's preferences, writing style and workflow patterns as it is used, and the terms describe the product as built on large language models and other AI features. Without the models there would be little beyond file storage.

Research results come with citations to precedents, statutes and case law across jurisdictions, and the product is said to cite its sources and verify its citations. The verification method, the research sources and whether a cited authority links through to its text are not described.

Under its terms Lexi makes no warranty on the accuracy of any output, tells users not to rely on output without confirming it independently, and warns that output may contain material inaccuracies even when it looks detailed. No accuracy figure, test set or error rate is published.

The pitch is AI associates that do the work and handle workflows end to end, with drafts that need minimal editing. Users are told not to rely on any output without confirming its accuracy independently.

No review surface, approval step, threshold at which the system stops, or route back to a lawyer is described for drafting, contract review or the onboarding that assembles case files. Audit trails are kept on documents, without a description of what they record.

More than 20 million documents across more than 200,000 cases for over 1,000 organizations and law firms have gone through the product, by Lexi's count. It also reports lawyers saving more than 10 hours a week and taking on 45% more cases without adding staff. No basis is given for these figures, and Lexi's Y Combinator profile gives lower counts of 5 million documents and 200 organizations.

One customer is quoted by name. Gagan Gupta, a senior designated lawyer, says his practice went from turning away two or three clients a month to taking every case. He credits Lexi with initial document review and contract analysis and puts the gain at three times the case capacity, without naming his firm. Coverage in the Deccan Chronicle and the Times of India is listed as press.

Client data is never used to train AI models, according to the security page, privacy policy and data controls page. Zero data retention agreements bind every third party generative AI provider not to store data beyond the immediate request or train on it. Personalization stays inside the account that produced it, and data is kept logically isolated between organizations.

Attorney client privilege is addressed by name: Lexi shares no communications or work product with third parties and recommends that firms consult their ethics counsel on AI use. The terms are looser than these statements. They license customer content for providing, improving and protecting the service, and leave training of Lexi's own models to a user setting whose default is not stated. A data processing agreement is available on request.

The terms describe Lexi as providing AI powered legal services and software to legal professionals and firms, while setting a minimum user age of 13 in the United States and 16 elsewhere. They make no warranty on output and tell users to confirm it independently.

No statement says that Lexi gives no legal advice or that a lawyer stays responsible for the work, and jurisdiction limits are not stated. The data controls page recommends that firms consult their ethics counsel about AI use in their jurisdiction and practice area.

An ISO 42001 certification for an AI management system is claimed, described as covering how Lexi's AI systems are developed and deployed. The certifying body, certificate scope and date are not given, and no certificate is published.

No AI policy text, accountable owner, test method or test result is published, and nothing addresses uneven output across practice areas, jurisdictions or the more than 100 languages the product works in.

Customers can ask for deletion at any time, and Lexi permanently removes the data within 30 days unless the law requires it to be kept. Other retention periods vary by data type and the account's settings, without stated periods. Data is encrypted with AES 256 at rest and TLS 1.2 or higher in transit, the database itself is encrypted, and staff access is limited to those who need it, under confidentiality agreements and regular training.

Role based access control, SSO and SAML, audit logging and regular penetration testing are listed, along with documented incident response procedures covering containment, investigation, notice within required timeframes and remediation. Service providers fall into broad groups such as billing, cloud and communications, and no named subprocessor list is published.

The terms, last updated 1 June 2026 under California law, disclaim liability for direct as well as indirect, incidental, consequential and punitive damages from use of the service or any output. Lexi takes no responsibility for errors in output. No cap is stated because no damages are accepted, apart from statutory liability for intent and gross negligence owed to consumers in the European Union and the United Kingdom.

The service and its output are provided as is. Customers indemnify Lexi for breach, for their content and for violations of law, and Lexi gives no indemnity in return, no warranty on output and no insurance position. Where Lexi discontinues the service early, prepaid fees for the unused term are refunded.

A Chrome extension carries Lexi into the browser, and the privacy policy describes access to Google user data through Google Workspace APIs under Google's limited use rules. Client onboarding draws on emails and meeting notes. Which practice management, document management or email systems connect, and what moves between them, is not documented, and a question about integrating with existing law firm software sits on the contact page without a published answer.

Data is processed in the cloud by default, on infrastructure with a 99.9% uptime SLA and built in redundancy, and on premises deployment is offered to firms that need it. Organizations are kept logically isolated from one another.

Customer data from outside the United States is transferred to and processed in the United States. The cloud provider and region are not named, nothing describes how on premises deployment differs, and a regional site for the United Arab Emirates carries no separate residency offer.

Certification to ISO 27001 for information security management and ISO 42001 for AI management is claimed. For SOC 2, compliance and alignment with the security, availability and confidentiality criteria are claimed rather than an audit report. No certifying body, certificate scope, date or report is published, and there is no trust center. Regular penetration testing and security audits are described, and a data processing agreement is sent on request.

Open source models run alongside large language model providers including OpenAI and Anthropic, chosen for accuracy and reliability. Every third party generative AI provider is bound by a zero data retention agreement that bars storage beyond the immediate request and any training on customer data.

The open source models, the model versions and where each runs are not named, and no notice is promised when the mix of providers changes.

No price, plan or unit of charge is published, and the pricing address on the site returns nothing. Buyers book a demo or schedule a call. An ROI calculator models the time a firm could save, and the terms refer to paid services and fixed terms without figures.

Solution pages address law firms, in house teams, corporate legal departments and litigation practices, and Lexi presents itself as one intelligence layer for lawyers, legal teams and enterprises. Research covers precedents, statutes and case law across jurisdictions, and work runs in more than 100 languages.

The solution pages describe outcomes rather than practice areas, and no jurisdiction, practice area or document type is named as supported or excluded. The regional site for the United Arab Emirates and offices in the United States, India, Australia and Singapore indicate where Lexi sells.
