In short

Rill (AI Chat) is a productivity app that puts several AI models in one chat place, using your own API keys stored in the device Keychain. It suits people who want to compare model responses in group conversations, edit prompts into branches, and search past chats, with no account required. A standout detail is that the full conversation history is sent without automatic summaries, and a built-in offline demo lets users try features without a key.

About

Rill brings your AI models into one simple place to chat.

CHAT WITH YOUR MODELS Connect the services you use with your own API keys. Discover their models and choose an exact version. Service availability and fees are set by your provider.

BRING MODELS TOGETHER Create private group conversations and compare responses. Each model keeps its own conversation context by default. Supported models can add a small reaction to a message and show public reasoning summaries.

KEEP THE WHOLE CONVERSATION Send text and images together. Edit an earlier prompt to begin a branch without losing the original. Rill sends the full applicable original branch history, without silent shortening or automatic summaries. If a service rejects the history size, your conversation stays intact.

READ AND FIND Read long answers continuously, with Markdown, tables and code. Search titles and message content, including archived conversations and older branches.

YOUR KEYS, YOUR CHOICE Keys stay in this device’s Keychain. No Rill account is required. Chats remain on your device; selected AI services process requests under their own terms.

TRY BEFORE CONNECTING Rill Demo is a clearly labeled offline, fixed sample—not a real AI model. Explore sending, groups, branches and reactions without a key or network.

Made for iPhone and iPad. English, Simplified Chinese and Traditional Chinese. Light and Dark appearances.
