Invitt: Invitations, RSVPs, Planning

Lets separate coding-agent sessions coordinate through a shared, role-addressed mailbox instead of a human relaying every message, over a single local SQLite file or a hosted server with many isolated channels. Messages can be sent as tracked obligations that stay open until one side resolves and the other confirms, alongside threads, full-text search, work statuses, and an append-only versioned pin system where protected changes require recorded agreement from every declared role.

Enables multiple AI agents and humans to collaborate in a shared chatroom with reliable @-mention delivery and context-preserving session injection.

Enables a user's AI to exchange messages with people they already know and those people's AIs in DMs and group chats, handle routine communication, and flag only items needing attention. It supports OAuth sign-in and private invite-based connections without a directory or search.

Enables multiple Claude Code instances to communicate through direct messages and topic-based channels. It features a real-time web dashboard for monitoring conversations and includes a persistent mailbox for offline message delivery.
