Why Octoii
One app. Every model.
Real agent power.
A real agent, not a chatbot.
Give it a task and walk away. Octoii runs multi-step missions — reading files, writing code, executing commands — then reports back when it's done.
Native & fast
SwiftUI + AppKit. Launches instantly, sips battery, never feels like a web wrapper.
Any model, one thread
Claude, GPT, Gemini, open-source — switch per message without restarting the conversation.
Your keys, your bill
Bring your own API keys. Zero markup on tokens. You pay providers directly.
Private by design
Prompts go straight to your chosen provider. We never see your conversations or files.
CLI & extensions
Use Codex CLI or Gemini CLI subscriptions. Custom workflow extensions coming soon.

FAQ
Common questions
Bring Your Own Key. You plug in your own API key from Anthropic, OpenAI, Google, or OpenRouter. Octoii never proxies your AI traffic — you pay providers directly at their published rates, with zero markup from us.
Octoii's agent can read files, write files, edit code, and run shell commands on your Mac. Give it a multi-step task — like refactoring a module, setting up a project, or investigating a bug — and it works autonomously until done.
ChatGPT desktop can't run commands or edit your files. Cursor is tied to VS Code and one provider. Octoii is a native Mac app that works across your entire filesystem, supports multiple AI providers, and runs long-lived agent tasks — not just chat completions.
The app stops accepting new prompts, but your data stays. Purchase a license (inside the app, via Stripe) and you're back instantly. No data loss, no re-setup.
Any Mac running macOS 14 Sonoma or later — both Apple Silicon and Intel. The app is universal, notarized by Apple, and updates automatically via Sparkle.
Yes. You can pick a different model for each message. Use Claude for complex reasoning, GPT-4o for speed, Gemini for long context — all in the same thread.
No. Your prompts and files go directly to the AI provider you selected. Octoii's servers only handle licensing and billing — never your AI conversations or workspace content.
