よくある質問
What does Contract Analyzer do?
You upload a contract and it returns a structured review — parties, key dates, obligations, financial terms, and flagged risks — so you can quickly understand what you're agreeing to.
What can I upload and what's the size limit?
Upload a contract as a PDF or scanned image, up to 10 MB. Both digital PDFs and clear scans of signed paper agreements work.
Is this legal advice?
No. It's an AI-assisted first-pass review to help you understand a document. It does not replace a qualified lawyer, especially for high-value or complex agreements.
How accurate are the flagged risks?
It reliably surfaces common terms and obvious red flags, but it can miss jurisdiction-specific nuance or unusual clauses. Always have important contracts reviewed by a professional.
Can I use it for any contract type?
It works across common agreements — NDAs, service contracts, leases, employment offers, and more. Highly specialized or non-English contracts may reduce accuracy.
Can I rely on the output commercially?
You can use the analysis to inform your own decisions and business. The free tier allows 5 uses per day with no signup; Pro is $19/month. It remains informational, not legal counsel.
Is my uploaded contract kept private?
Yes. Your contract is processed to generate the review and then discarded — it isn't stored long-term or used for model training.
