Twosure turns a rough note into a clean agreement. Send one link, and everyone verifies by SMS or photo ID + face match and signs in their phone browser. Once finalized nobody can edit it, and a QR seal proves it's real. 2-5 parties, from $1.99.
Hi Product Hunt! I'm Takuma, a solo developer in Tokyo, and I built Twosure.
The problem is common and nobody has a lightweight answer to it: you lend a friend money, you sell something to a stranger from a marketplace, you split rent with a roommate. A few months later everyone remembers the terms differently, and if the other person goes quiet you often don't even know their real name. A contract template doesn't solve this. The missing piece isn't the wording, it's knowing who signed it.
So Twosure does two things and stops there.
1) An agreement you can actually read. You type what happened in your own words ("lent a friend $1,000, paying it back by the end of September, bank transfer") and AI shapes it into clauses: who, to whom, what, by when, asking fill-in questions for whatever's missing. Or start from one of 26 templates.
2) A trail to the other party. Signing requires verification. At $1.99 you get their SMS-verified phone number (line type checked, so burner VoIP numbers show up). At $6.99 you get the name and address from their photo ID plus a face-match result. That record lives inside the signature block of the document itself.
You send one link. Everyone signs in their phone browser, no app, 2 to 5 people, from anywhere, in 12 languages. Once finalized nobody can change a word, and the red seal carries a QR that opens a verification page so a third party can check the sheet is real.
Pricing is $1.99 or $6.99 per agreement, paid only by the person who creates it. The other party never pays. No subscription.
One thing I want to be straight about: Twosure produces evidence, not a guaranteed-enforceable contract. Whether a document holds up depends on your jurisdiction and your situation. What I can promise is that the terms are fixed, both identities are on the record, and nothing can be altered afterwards.
What I'd love feedback on: when you've been burned by a verbal agreement, would you have paid $2 upfront to avoid it? Or does asking someone to verify their ID make the request feel like an accusation? That social awkwardness is the part I'm least sure I've solved.
