Everything you need to know about how ClauseCheck works.
A browser-based contract scanner for freelancers and small businesses. Scan SOWs, MSAs, NDAs, and more — it flags risky clauses with plain-English explanations and suggested redlines. Use it on any device with a browser. Chrome extension is live now (with right-click scanning from Gmail, Google Docs, and any web page). Edge coming soon.
No. ClauseCheck is an automated tool. Its output is informational only and is not a substitute for a licensed attorney. The AI may be wrong, incomplete, or inappropriate for your specific situation and jurisdiction. For material contracts, always consult a qualified lawyer.
Your uploaded file never does. When you upload a PDF or DOCX, it is parsed entirely in your browser using local JavaScript — the raw file is never sent to our servers. Only the extracted plain text is transmitted to our API for scanning. Pasted text is sent directly. We do not store your contract content after the scan completes.
No. After scanning, we log only clause categories flagged, token counts, and model cost — never the contract body itself. Your content is not retained after the request completes. See our Privacy Policy for full details.
No. Your contract text is never used to train any model — ours or anyone else's. Scans are stateless API calls to Anthropic. Per Anthropic's commercial API terms, API inputs and outputs are not used for model training.
15 clause categories tuned for freelancers: auto-renewal, IP assignment (including pre-existing IP), unlimited liability, kill fees, scope-creep language, non-compete / non-solicit, arbitration, governing law, NET 60+ payment terms, unclear milestones, moral rights waiver, exclusivity, confidentiality, unilateral termination, and warranty disclaimers.
Our internal eval harness measures F1 = 0.88 (precision 0.82, recall 0.94) across 16 labeled synthetic contracts covering all five role profiles. AI analysis can still miss clauses or flag things incorrectly — treat it as a first pass, not a final answer.
Free forever: 5 scans per month, all 15 clause categories, severity ratings. Pro: $3.99/mo or $29/yr — unlimited scans, suggested redlines, PDF export of reports, role-specific scoring, kill fee calculator, benchmark data. Lifetime: $39 one-time, everything in Pro, capped at the first 500 users.
Unlimited scans (Free is 5/month), suggested redlines per clause (copy-paste replacement language), PDF export of your scan report, role-specific severity scoring (designer / developer / writer / consultant), and anonymous clause benchmark data. Free users still see all flagged clauses and their explanations.
Yes. Cancel from your Account page via the Stripe Customer Portal. You keep Pro access until the end of the current billing period with no charges after that.
Lifetime is a one-time $39 payment that covers all current and future Pro features, forever, with no subscription. It's a launch-only deal capped at 500 users — once those slots are gone, Lifetime is no longer available. Core features (scanning, redlines, role profiles, PDF export, benchmarks) are guaranteed to remain included.
PDF (text-based only — scanned / image PDFs are not supported in v1), DOCX (Word), TXT, and Markdown (.md). Max 5 MB per file. Files are parsed client-side in your browser; only the extracted text is sent to our API.
No. The web app at clause-check.app/scan works on any browser including Safari and Firefox, on desktop and mobile. The Chrome extension (live now) and Edge extension (coming soon) add right-click scanning directly from Gmail, Google Docs, and any web page — no copy-pasting required. Both use the same backend, limits, and pricing. Get the Chrome extension: https://chromewebstore.google.com/detail/dmfkeoijggalpdonblfmlkpbhppfmjgj
Chrome and Edge (MV3 format). The extension should also work on Chromium-based browsers like Brave and Arc, but these are not officially supported. The web app works on any modern browser.
