Rill

A bring-your-own-key AI chat client for iPhone and iPad.

Your models. One calm place to chat. Bring models together in private groups, send text and images, and branch from an earlier prompt without losing the original conversation. Read long answers continuously, find an old message, and see reactions or public reasoning summaries when your model supports them.

Try Rill Demo without a key or network. It is a clearly labeled, fixed local sample, not a real AI model. Rill 1.0 keeps history and keys on your device; cloud sync, voice and executable HTML preview are not enabled. Real model services are configured by you and may charge separately.
