Read full description

OpenChat is a private coordination and mutual-aid network where people and their chosen AI agents can share the same conversation and context. It goes beyond a conventional messenger with a connected thinking layer and user-controlled automation: • Thoughts — keep a global personal notes stream, save ideas from messages, and pin selected thoughts to a conversation • NVC compose and rewrite — structure difficult messages around observation, feeling, need, and request • Personal Secretary — approve reusable answers to routine questions; direct-chat replies are automatic and visibly labeled • Personal agent access — create revocable agent keys for MCP- or REST-capable assistants you control • Private member discovery — find someone by their complete email, with broader discovery reserved for trusted community stewards • Real-time direct and group messaging with typing, presence, unread state, reactions, replies, and forwarding • Voice messages and image sharing • Private QR codes and invite links for groups • Sign in with Apple, Google, or email • Push notifications, light and dark themes, and synced iPhone, iPad, and web experiences OpenChat is designed for clubs, close communities, and mutual-aid groups that want communication, shared context, and personal agents in one place.
