Run Pi in ace
The Pi coding agent, run from its own command-line tool. ace runs it through your own signed-in CLI and adds what a terminal can't: every task in its own thread, a status that covers its subagents, and tools to see and test what it builds.

Questions about Pi in ace
Does ace need a Pi API key?
No. ace starts Pi through its own command-line tool, signed in the way you already use it, so your existing plan keeps working. ace never asks for, stores or proxies credentials.
Can I run Pi beside other agents?
Yes. Run Pi, Claude Code, Codex, Cursor and others side by side, each thread in its own git worktree, and hand a thread from one agent to another with its context.
Can Pi hand work to other agents?
Yes. Pi can delegate tasks to agents on other providers and on your other machines with ace's delegate tool, and wait for their results.
Can Pi use a browser and my desktop apps in ace?
Yes. ace gives Pi the same MCP tools as every other agent: a real browser, computer use, phone simulators, and delegating to agents on other machines.
