No server · your key & messages go straight to your provider

Keychat Pro (coming soon)

Keychat is free and stays free — paste your own OpenAI or Anthropic key and chat with no account and no backend. Pro is an optional one-time upgrade for power features, and it keeps the same promise: Your key and messages go straight from your browser to your chosen AI provider — we run no server.

One-time Pro upgrade

Pay once, use forever on this device. No subscription.

What's in Pro

Most of these ship in Pro today — on-device WebLLM is the one roadmap item still ahead on this build.

  • On-device models (WebLLM)

    Coming soon

    Run small LLMs entirely in your browser via WebGPU (WebLLM) — no API key, no network, no per-message cost. Great for quick, private drafts.

  • Prompt presets

    Save and reuse your own system prompts and quick-start templates. Switch personas or tasks in one click.

  • Chat with PDF & files

    Drop in a PDF or text file and ask questions about it — parsed in your browser, threaded into the conversation.

  • Export & share

    Export a conversation to Markdown or plain text, or copy a clean snapshot of a thread.

  • Multi-conversation sidebar

    Keep several chats side by side, each named and searchable, all still stored locally in your browser.

  • No analytics, ever

    Pro builds ship with analytics fully off — not even the privacy-friendly kind. Nothing leaves your device unless you call a provider.
