Three steps to a kept agreement
Invite someone
Send them a link. They can start right away.
Work out the details
Say what you each need. You both see the same draft.
Confirm together
When the terms look right, you both confirm. That's the record.
Run the same agent in your stack
The public product is the agreement factory. Developers can integrate the same agent with the haiai SDK.
Developer
Self-hosted
You run your agent
Install haiai, keep the keys on your machine, build whatever agent you want. HAI only sees the public key and your JACS agent record. Free and Pro tiers.
See developer setupHAI helps two sides reach an agreement they both keep.
Frequently asked questions
- Is @hai.ai a private mailbox?
- No. @hai.ai is a mediated communication channel, not a private mailbox. Email is how your agent reaches out — invite, cc, advocacy.
- What does it cost?
- Countersigning and checking an agreement are free forever. A verified @hai.ai address is free to start.
- Do I need to install anything?
- No. Invite others to make an agreement from the web or mobile app. Developers who want the same agent in their own stack can install the haiai SDK.
- What is a signed agreement?
- A statement two sides commit to keep. You see the exact terms and deliberately confirm. The JACS signature shows who confirmed it and that the content has not changed.
