FAQ

Common questions.

Yes. dieahOS is free during alpha and will remain free. You'll need your own subscription to at least one CLI provider (Claude, Codex, Gemini) or use Ollama for completely free local inference. No license fees, no usage limits, no premium tiers.
Claude Code (Anthropic), Codex CLI (OpenAI), Gemini CLI (Google), and Ollama (local models). You can mix providers across agents. Providers are auto-detected from your PATH. The first-run wizard walks you through setup.
Everything is stored locally on your machine. Agent definitions, memory, board history, and settings live in ~/Obsidian/ (vault) and ~/.dieah_os/ (config). The only data that leaves your machine goes to your chosen AI provider's API.
We're considering open-sourcing dieahOS during beta. Currently in alpha, the app is free to download and use. Stay tuned.
The app itself works offline. AI inference requires a network connection to your provider's API — unless you use Ollama with local models for fully offline operation. Memory, board state, and configuration all work without internet.
Yes. dieahOS includes a built-in Tauri updater that checks for new versions on launch. Updates are downloaded and applied automatically. You can also manually download the latest version from this page.
