The NDA review tool is for lawyers and business teams checking a non-disclosure agreement (NDA) before it is signed. Paste the whole agreement, say whether you disclose, receive or both, and get each finding marked Review, Note or OK, with the text it matched. It is free, with no account and no usage limit. What you paste stays in this browser tab.
It works in any current browser with JavaScript turned on. There is nothing to install and nothing to sign up for.
The NDA review tool uses fixed rules that look for wording patterns in the pasted text; it does not use AI, and the same text and side always give the same result. It runs 14 checks. Each finding is marked Review (a term to negotiate or confirm for your side), Note (worth reading; whether it matters depends on your deal) or OK (the usual protection is there, or nothing was found that works against your side), with the sentence that triggered it or "Not found in the text."
Your side changes the label, not what is found. Terms that put a burden or restriction on the recipient are Review when you receive. Gaps that leave shared information unprotected are Review when you disclose. For a mutual NDA you are on both sides, so either kind can be Review.
Definitions of terms such as confidential information and injunctive relief are in the Gavel clause library. Rules last updated November 14, 2026 (rules v1.0).
Example (fictional): the "Try an example" NDA is a one-way confidentiality agreement dated March 3, 2026, in which Northwind Analytics, Inc. is the disclosing party and Brightline Health LLC is the recipient. Its definition covers all information "whether or not marked", it lists only two exclusions, the obligations "continue in perpetuity", and it has a 24-month non-solicit. Reviewed as the receiving party, the NDA review tool returns "Reviewed as: Receiving party. 4 to review, 7 notes, 4 OK." The four Review items:
The seven Notes are: One-way NDA: only one party's information is protected; Oral disclosures are covered; Agreement term: two (2) years; Return or destruction required, with no exception for backups; Injunctive relief clause; Governing law: Delaware; Exclusive venue named. The four OK items are: Sharing with representatives on a need-to-know basis; Compelled disclosure allowed, with notice; No residuals clause; Neither party may assign without consent.
Switch the side to Disclosing party and the same text gives "Reviewed as: Disclosing party. 0 to review, 6 notes, 9 OK." The broad definition and the perpetual term become OK, and the non-solicit becomes a Note. As Both (mutual), the result is 3 to review: the one-way structure, the missing exclusions and the non-solicit.
Copy the findings or download them as a .txt file and keep them with the NDA, or send both to the lawyer who signs off. The NDA review tool checks one NDA against Gavel's fixed rules. Gavel Exec, Gavel's paid AI contract review product for Microsoft Word and the web, reviews the whole agreement against your own playbook: each rule passes or fails with its reasoning, and it proposes changes. See Gavel Exec contract review; each user starts with 25 free queries and no credit card, and current prices are on the Gavel Exec pricing page.

No. The NDA review tool runs in your browser: the text you paste stays in that tab, is sent nowhere and is not kept after you close the tab. The tool's own code makes no network requests; the page around it, like the rest of gavel.io, loads its own site scripts such as analytics. Follow your firm's confidentiality policy for client documents.
Yes, it is free, with no account and no usage limit. Open the page, paste the NDA and select Review this NDA.
No. The NDA review tool uses fixed rules written by Gavel that look for wording patterns, so the same text and side always give the same findings. Gavel Exec, Gavel's paid contract review product, is the one that uses AI.
Because the same clause helps one side and burdens the other. A definition that covers everything disclosed, marked or not, protects the disclosing party and is extra work for the recipient, so the NDA review tool marks it OK for the disclosing party and Review for the receiving party. The text it finds does not change, only the label.
Yes. Choose Both (mutual). The NDA review tool then marks a term Review when it would matter to you in either direction, for example missing exclusions or a non-solicit, and flags a one-way NDA as Review because your own information would not be protected.
No. The NDA review tool reads plain text only. Open the NDA, select all the text, copy it and paste it into the box; the tool accepts up to 100,000 characters.
