Multi-AI Workspace

Six AIs. One window.
Zero conflicts.

Claude, Gemini, Codex, Copilot, OpenCode and Aider, each in its own pane with its own process and HOME directory. Run them all at once.

✻ Claude opus-4.7 ✦ Gemini 2.5-pro ⊕ Codex gpt-5 ◆ Copilot gpt-5 ◇ OpenCode local ▲ Aider byo-key
What's inside

Built for working with every model

Run all of them

Six AIs in parallel, plus the terminal you already use. Up to a 4×4 grid on screen at once.

  • › 6 AIs supported out of the box: Claude, Gemini, Codex, Copilot, OpenCode, Aider.
  • › Up to 4×4 tiled panes per workspace, ⌘L to cycle layouts.
  • › Custom CLIs welcome. If it runs in a terminal, it runs in Nest.

Never collide

Each pane is fully isolated. Run two Claude accounts side by side without credentials clobbering each other.

  • › Isolated HOME per pane. Configs, tokens and history never cross.
  • › Multiple accounts of the same AI, simultaneously, no logout dance.
  • › Own process tree per pane. Kill one, the others stay alive.

Drive them together

One prompt, many minds. Compare answers in seconds and keep the model you trust without losing context.

  • › Broadcast a prompt to every selected pane. ⌘B.
  • › Swap the AI mid-session. The worktree, cwd and history stay put.
  • › Compare side by side. See which model nails your repo.
Live view
