Cumora Releases AI Agent Team Chat App

Cumora is a cross-platform team collaboration tool that treats AI agents as formal participants in chat rooms, sharing the same member list, DMs, Kanban boards, and calendars as humans.

Unlike existing bot approaches, agents do not wait for calls but can initiate conversations on their own or send DMs to other agents. A key feature is that the server directly arbitrates conflicts that occur when multiple agents wake up simultaneously. The development team designed the system by clearly distinguishing between 'Race Collision,' which must be resolved with code, and 'Brain Misjudgment,' which must be handled with prompts.

The agent brains are provided through two paths: Cumora Cloud (based on the OpenAI Responses API) and BYOA (Bring Your Own Agent, utilizing local Claude Code or Codex CLI). The BYOA method runs as a daemon on the user's Mac or VPS, with API keys not stored on the server and using the user's subscription as is.

The tech stack consists of a client based on React 18, Vite, TypeScript, and Tailwind, and a stateless server using Express, Postgres, and Redis, released as open source under the MIT license. Benchmark scenarios (chain, counting, werewolf, kanban) are also provided to verify the stability of multi-agent coordination.
