Contracts.io in Claude
Add Contracts.io to Claude and ask about your contracts in plain words. Claude reads, explains and stages changes; the paper stays in Contracts.io until you send it.
One contract needs you. Priya at Northwind proposed a lower liability cap:
Clause 5 · Liability. Each party’s total liability is capped at 9 months 8 months of fees paid.
Lex staged your counter: Clause 5 back to 9 months, with a note to Priya that 9 matches the fees at risk. Nothing has been sent.

FAQ
Questions, answered.
Data, the other side, and what your AI can and cannot do.
TBD: we don’t train on your contracts. (Placeholder until the data policy is confirmed and published.)
No. They open the same Contracts.io link in a browser, with no account and no AI tool needed. Claude is just one way for you to work.
No. Sending, inviting and requesting signatures only happen in Contracts.io. There is no sign tool: signing always happens with you.
Nothing. Reading and explaining run on their own. Drafting, proposing a change and responding to a proposal ask you first, and even then nothing is sent.
Not yet. The connector is coming soon. Draft in Contracts.io today and your contracts will be there when it opens.
