ContractGPT

Most businesses sign contracts they haven't fully read. Legal review is slow and expensive, so routine agreements — vendor terms, leases, client contracts — get signed on trust and skimming, and the bad clause is found when it bites.

ContractGPT reads the document first. Upload a contract and it flags the risky parts directly on the PDF — clauses highlighted where they actually sit, graded by risk — pulls out the key terms like payment, termination, liability, and auto-renewals, and answers plain-language questions about what you're agreeing to, grounded in the document itself so it can quote the line it's talking about. It also works the other direction: it drafts amendments and shows them as redlines against the original, and it can create a new contract from a conversation, with the document taking shape live as you talk.

It doesn't replace a lawyer; it tells you when you need one, and arms you for that conversation.

Under the hood it's Next.js and Supabase, with contracts going to Claude as the PDF itself rather than through a brittle text-extraction step, Pinecone retrieval keeping answers anchored to the contract with fallbacks so the chat still answers when an index misses, clause highlighting driven by the PDF's own positional data instead of fragile text matching, a react-pdf reading pane, and Stripe subscriptions. There's a demo video on this page, and you can try it live.
