RogerAI is a two-way radio for AI. Tune into open models running on real GPUs, ask anything, and pay only for the tokens you use. WHAT IT DOES - Chat with powerful open models, plus Apple Intelligence on device: free and private. - Browse the Band, a live marketplace of stations with real prices and speeds, so you pick the cheapest or fastest for the job. - Connect any OpenAI-compatible app to your own endpoint. The same key works in Cursor, a chat app, Raycast, Python, or curl. BUILT FOR PEOPLE, NOT JUST DEVELOPERS - Talk instead of type: dictate your message and have replies read back, hands-free. - Send a photo and ask about it on vision-capable stations. - Keep multiple conversations and pick up where you left off. - Select and copy any part of a reply, the way you expect. AN AGENT WHEN YOU WANT ONE - Turn on agent tools to let the chat take real actions: open an app or link, run one of your Shortcuts, read a web page, check your calendar, or jot a note. Every action asks first, and shows exactly what it will do. PRIVATE BY DEFAULT - Start anonymous: no account needed for on-device and free stations. - On-device replies never leave your phone. - Confidential routing can send only to nodes that pass real hardware attestation. Roger is the control room for a new kind of AI: open, metered, and yours. Broadcasting live from Orange County, California.
