Agent
Named agents with a brief, a memory file and routines that run them on a schedule.
Run the agent CLIs you already pay for, side by side on your Mac.
Public beta · free until 1 Oct 2026 · macOS 14 or later · notarized by Apple

Each engine keeps its own sign-in and subscription.
Delegation gets real work out of an agent without trusting it blindly.
Five parts: workspace, goal, hard rules, verification duty, completion criteria. The worker runs in its own worktree.
The app re-runs the checks itself. A reviewer on another engine judges brief and diff and ends with a verdict.
The result waits in the Inbox with Merge, Squash, Create PR or Discard. Nothing merges on its own.


Three ways to work with the same engines, one sidebar that keeps track.

Named agents with a brief, a memory file and routines that run them on a schedule.

Real terminals side by side in a folder, with Files, Changes and a browser as panes.

A structured thread over each engine's own protocol. Approvals wait above the composer.


Read the diff with per-file counts, then merge, squash or open the pull request from the same panel.
Worktrees and Changes in the helpReview with or continue in any installed engine. The transcript travels; credentials are redacted before it goes.
Hand-offs in the help

Off until you turn them on; frames and versions, not text.

No. The engines talk to their vendors directly; nothing passes through Shelzo's servers.
The free beta ends and Pro pricing is announced. Your engine subscriptions stay separate.
Start with one folder and one engine; add worktrees, hand-offs and routines when the work asks for them.
