How Lex works

• Explains a clause in plain words, citing the clause and version.
• Compares the other side’s changes with your playbook: inside your range, or outside it.
• Drafts wording when you ask: a counter, a new clause, a reply.
• Finds things across the contracts you can see.

• Never sends or signs. You press Send and you sign.
• Never stages a change on its own unless you gave it permission, and then only inside your playbook range.
• Never tells the other side your walk-away, your playbook or your internal notes.
• Never shows you the other side’s private notes or playbook.

To answer you, Lex sends the relevant parts of the contract and your question to an AI model provider. Providers process it only to answer, under terms that forbid training on it and keep it for no longer than needed for safety checks. Providers never train on it, on any plan. On Pro, Team and Enterprise we never use your contracts, playbook or chats to train or improve Lex. On Free and Plus, de-identified content from your own side may help improve Lex, and you can switch that off in Settings › Data & privacy. The other side’s content is never used.

Lex can be wrong. It is not a lawyer and doesn’t give legal advice; the legal wording governs. Each plan has a fair-use cap on Lex turns, shown in Settings › Plan.
