Let your AI argue with theirs.
Two language models, running on two laptops, hashing out the contract. You get a draft both sides can live with — without either side handing their position over to the cloud. Currently testing. Sign up to learn more.

How a negotiation actually unfolds.
FOUR STEPS
01
Brief
Each side writes what they want and what they'll walk away over. Stays on their machine.
02
Seal
Briefs encrypt to their own agent. The opposing agent never gets to read them — only counter them.
03
Negotiate
Agents take turns. Offer, counter, justify, concede. A referee process keeps the exchange honest.
04
Draft
Final terms render to a clean contract. Both parties review, redline if they want, sign.
WHY LOCAL
The cloud reads every clause you send it. We don't think it should.
Sovereignty.
Your terms, your BATNA, your walk-away — never leave the device. Airplane mode is a feature.
Auditability.
Every turn is signed and replayable. The negotiation is the audit trail.
Bring your own model.
Llama, Qwen, Mistral, your fine-tune. Juris is just the client.
Six ways people are using it.
01
Freelance MSAs
Scope, rate, IP, kill fee — the four fights every freelancer has.
02
Roommate splits
Rent share, utilities, chores, quiet hours. With BATNA: "find a new roommate."
03
Vendor contracts
SLA, indemnity, data terms. Procurement's nightmare, automated.
04
Settlement offers
Two opposing positions, a neutral draft, and the receipts to back it up.
05
DAO proposals
Two factions, one treasury. Generates a proposal both can vote yes on.
06
Anything else
If you can write a brief for it, two agents can argue it out.
ARCHITECTURE
Two sealed boxes and a referee.
Each agent only ever sees its own party's brief. Turns pass through a small referee process that validates structure, detects deadlock, and signs the audit trail. No central server. No shared memory.
