How it works
From brief to signed, in one sitting.
- 1
Write
Tell the AI what you'll do and for how much, or start from a template. Price tables add up as you type.
- 2
Send
Add who signs, in order or all at once. Each gets a private link from your company's name.
- 3
Signed
They tick options, draw or type a signature, and everyone gets the signed PDF with its certificate.
Close deals faster
Everything between 'send me a proposal' and 'signed'.
Rewrite any section
Clearer, more persuasive, shorter, more formal or fairer, in one click.
Optional extras
Clients tick the add-ons they want while signing. Upsells without a second email.
Know when it's opened
See who opened it and when, and chase with a fresh link in one click.
Tamper-evident
The document is fingerprinted when sent and checked before every signature. Changed? It can't be signed.
Certificate of completion
Every signature, IP and step on the last page of the signed PDF.
Automatic reminders
People whose turn it is get a nudge every few days until it expires.
Review before you sign
Risky clauses flagged by keyword and explained by AI, with wording to ask for instead.
Honest by design
It writes and explains. You decide what's signed.
The AI does
- Drafts from your brief, using only your prices
- Leaves '…' where it doesn't know, and won't send until it's filled
- Quotes risky clauses exactly, and checks the quote is in the contract
- Explains contracts in plain words with changes to ask for
It never
- Invents prices, names, dates or laws
- Changes a document after it's sent
- Calls its review legal advice
- Trains on your contracts (private models only)
