1Download & install the app for macOS (.dmg) or Windows (.exe). No account, no signup.
2Bring your own keys (BYOK): add an API key from OpenAI, Anthropic, Google & more — or run local models via Ollama / LM Studio for a fully offline setup. Usage is billed directly by your provider; with local models there are no usage costs at all.
3Everything stays local: chats, documents and keys are stored on your machine only. Requests go directly from your computer to your provider — we never see your content, and telemetry is disabled.
4Chat, documents & agents: multi-model chat, chat with your PDFs and files, and @agent for web search, charts and file tasks.
Note: the desktop app is a separate product with its own feature set — it may not include everything from the web app, in particular AI Collaboration, Compare Mode and the creation Studios. Web plans and the desktop app are independent of each other.
