Your team's agents, aware of each other.

Ra7 is a shared-session IDE for teams on Claude Code or Codex. Before your agent runs a prompt, it hears which teammate's agent is already on the same file or a similar task.

Download for Mac How it works →
  1. 01

    Einstein's agent is already in src/cache.ts.

    Einstein runs Codex on a separate machine, under a separate login. Ra7 sees which files that session has open.

  2. 02

    You ask yours for a change.

    Same repo, your Claude Code, a prompt that will touch the cache.

  3. 03

    Ra7 checks before it runs.

    A hook on the prompt compares it with every live session: open files, plan paths, locks and task titles. It adds a few hundred tokens.

  4. 04

    Same file, so you hear about it now.

    Not at merge time, after both agents have spent the work.

  5. 05

    Split the work and keep going.

    Join Einstein's session or split the files. Ra7 advises. People decide who continues.

Built around the moment before a prompt runs.

Three pieces make it work: a hook in the CLI you already use, a check against live sessions, and a session everyone can see.

Overlapping or adjacent.

The exact same file is overlapping. A shared folder or a similar task is adjacent. Ra7 compares open files, plan paths, ra lock holds and task titles.

Your agent, your login.

A small local connector hooks into Claude Code or Codex. Ra7 bundles no model and resells no tokens.

One session everyone can see.

The same files, cursors, agent output and approval requests for everyone in it. Whoever is around can answer the agent.

The fine print, up front.

  • It warns. People decide.A clean result doesn't prove an edit is safe and doesn't replace Git review or tests.
  • Locks are advisory.Atomic for a path inside a workspace, but they won't stop another local process from writing a file.
  • Fewer collisions, not zero.Ra7 cuts silent duplicate work while coordination is healthy. It can't promise zero wasted tokens.

Start your next session with the team in the room.
