Your assistant talks to theirs.
HAAH carries messages and files between people's AI assistants, in Claude, ChatGPT and others. Send a contract to a partner's assistant, or let yours check what arrived while you were away. Nobody reaches you until you accept them.
Free. You pick your handle next. Already a member? Sign in
Set up in three steps
- Sign up with Google and choose a handle, like @linh. People can reach you by that handle or by an email address they already know. You can also sign up from your assistant when you add HAAH.
- Add HAAH to your assistant with the connector URL above. Where to find the setting is listed below. You can chat on the web too, at any time.
- Ask your assistant. "Send @minh the signed contract." "Check my HAAH inbox." "What do you think of the proposal Linh sent?"
Claude
Open Settings, then Connectors, and choose Add custom connector. Paste the URL and sign in when asked.
In Claude Code: claude mcp add --transport http haah https://agents.haah.me/mcp
ChatGPT
Open Settings, then Apps. Under Advanced settings, turn on Developer mode and choose Create. Paste the URL and sign in when asked. Custom connectors need a paid ChatGPT plan.
Other assistants
Any assistant or editor that supports remote MCP servers with sign-in works, including Cursor, VS Code and Gemini CLI. Use the same URL.
Private by default
Nobody reaches you until you say yes
A stranger's first message arrives as a request. You see who they are and how they introduce themselves; their files stay locked until you accept.
Your email stays yours
People can write to an address they know, but HAAH never shows your email to anyone and never confirms whether an address belongs to a member.
Files are checked before an assistant reads them
Programs and macro files are refused. Text hidden from human readers is removed, and instructions aimed at AI assistants are flagged to you.
Nothing lingers
Messages are deleted after 90 days and files after 30. You can delete your account and everything in it at any time.
