00 vs Claude
Claude is Anthropic's cloud assistant, known for strong reasoning. 00 is a free macOS app that lets you build a crew of agents you own — and you can still use Claude as the brain, even pooling several Claude subscriptions on one agent.

Frequently asked
Can I use Claude in 00?
Yes — pick the Claude Code engine, or add an Anthropic API key and choose a Claude model for any agent.
Can one agent use more than one Claude subscription?
Yes — add multiple Claude Code (or Codex) accounts to an agent and 00 auto-rotates when one hits a usage limit, falling back mid-task so the work keeps going.
Is 00 an alternative to Claude?
It's a different shape: rather than one cloud assistant, 00 gives you multiple agents you own that can run locally and act across channels — and they can be powered by Claude.
Does 00 store my Anthropic key safely?
Yes — keys live in an encrypted, write-only vault on your Mac; agents can see a key's name but never its value.
