Find precedent that matches your facts.

No. LegiMatch is a research tool for licensed attorneys. It shows past court decisions, their outcomes, and why they're similar to your facts. It never recommends strategy or predicts outcomes. You verify and decide.

Search results can't include invented cases: every result is a real decision stored in our database, with a link to its text, and a final check drops anything that isn't in the database. The AI writes explanations, and like any summary those can be wrong, so read the opinion before you rely on it.

It's a transparent similarity score: facts 40%, legal issues 30%, statutes 15%, jurisdiction 10%, recency 5%; in an AI search, Claude's similarity rating counts for half. You can see every part and re-weight it. It is not a probability of winning.

Public-domain US court opinions from state appellate courts, federal district, bankruptcy and appellate courts, and the US Supreme Court, updated daily. We only use the courts' own text, never publisher headnotes.

Uploads are encrypted, stored on US servers and never used to train AI, and you can delete them any time or set auto-delete. Emails, phone numbers and SSNs are redacted automatically before processing. See the Security page for details.

Research is unlimited on every plan. Each plan includes monthly AI credits per user: an AI-powered search uses 1 (AI ranking plus written explanations) and Deep Analysis uses 5. When your AI credits run out, research keeps working with standard matching until they renew, or you can buy a top-up; top-ups expire with your plan period. Brief checks, keyword search and analyzing your matter never use credits.

It helps, but it isn't a full citator. Decisions show a red, yellow or green flag based on how later decisions in our database treat it (overruled, reversed, criticized, followed…), with the exact sentence. Brief check runs the same check across every citation in your brief, plus case-name, quote and pin-cite checks, and builds your table of authorities. Coverage is growing; always verify before filing.

Fact-matched research (standard matching once your AI credits are used), brief checks with a table of authorities, keyword (terms-and-connectors) search, reading and downloading opinions, alerts, statute pages, judge analytics, matters, notes and highlights, and the Research Librarian. AI credits are used only for AI-powered searches (1) and Deep Analysis (5). Unlimited means normal use by one attorney; automated or shared use isn't allowed. The statute finder and keyword search stay free even after a trial ends.

Yes. The Word add-in checks the citations in the document you're drafting and inserts Bluebook citations at the cursor.

The Research Librarian answers research and how-to questions 24/7 (it never gives legal advice), and one click hands any conversation to a person on our team, who replies in the app.

Each seat is for one attorney. An account can be signed in on two devices at a time (for example, laptop and phone). Signing in on a third device signs out the oldest one.

Yes. Annual billing costs 10 months' price for 12 months (2 months free), and you still get your AI credits every month.

Yes. Cancel any time in Settings → Plan & billing: you won't be charged again and you keep access until the end of the period you've paid for. Because you can try LegiMatch free for 14 days first, payments are non-refundable, except for billing errors or a technical problem on our side. Asking for a refund also cancels your next renewal. See the Refund Policy.
