You choose the brain
RAPR AI connects Claude Code, Gemini CLI, Codex, Ollama, OpenRouter and custom CLIs. Switch AIs mid-conversation, or give each step of a pipeline to a different model.
Grok Bot alternative
A self-hosted Grok Bot alternative with the AI of your choice.
Grok Bot launched in early beta as an always-on agent on a cloud computer managed by xAI. If you want the same persistent-agent feel on hardware you control, and the freedom to pick the model, RAPR AI runs on your PC and works with whatever AI you already use.
Kelvin, the RAPR AI penguin, shows what every agent is doing.
Self-hosted on your Windows PC, open source under MIT
Pick the model per task, or run several AIs in parallel
Kelvin, an animated status mascot, on your desktop and in the tray

Persistent, on your terms
Schedules keep running while the window is closed, Kelvin keeps the PC awake while agents work, and RAPR can start with Windows. Check on everything with /kelvin on Telegram.
A face for every agent
Like Grok Bot’s animated avatar, Kelvin turns agent state into expressions. Kelvin also appears once per agent when several run in parallel.
