Frequently asked questions
Is LegalDeep AI a substitute for an attorney?
No. LegalDeep AI is a legal research and drafting assistant. It does not provide legal advice, does not create an attorney-client relationship, and should be reviewed by a qualified legal professional before use.
How accurate are the citations?
LegalDeep AI is designed to produce source-backed answers with citations for review. Users should still open the cited authorities, confirm quotations and jurisdiction, and verify that the source is current before relying on it.
Which jurisdictions are supported?
The app supports U.S. federal research plus all 50 U.S. states and the District of Columbia. Users should still confirm local rules, court requirements, and source currency before relying on an answer.
Is my uploaded document private?
Uploaded matter documents are scoped to your account and matter workspace. You should still avoid uploading privileged or sensitive material unless your organization has approved that workflow.
What sources does LegalDeep search?
LegalDeep AI can use public legal web sources and your uploaded matter documents, depending on the source mode you choose. Answers show source context so you can inspect the basis for the response.
Do you offer a free trial?
Yes. LegalDeep Pro plans include a 3-day trial when checkout is available for your selected plan.
