24 models, one tap away
Open-weight favorites and frontier flagships side by side. Filter by Recommended, All, or Open models and pick your default.
Chat with the best open-weight and frontier models — DeepSeek, GPT-5, Gemini, Llama, Kimi and more — in a fast, beautiful app built for Apple devices.
Free plan included · 1,000 messages every month · No API key required.
Switch between models in a tap and use exactly the right tool for the job — without juggling a dozen subscriptions.
Open-weight favorites and frontier flagships side by side. Filter by Recommended, All, or Open models and pick your default.
Dial thinking effort from Instant to High per message. Watch the reasoning trace, or skip it for a fast answer.
Let the model search the live web and cite its sources, so answers stay current and verifiable.
Drop in a document or a photo. Images are compressed on-device; PDFs are read by every model.
Your chats, prompts and projects follow you from iPhone to iPad to Mac, instantly and securely.
A bold, native interface built on iOS 26's Liquid Glass — dark, fast, and right at home on Apple hardware.
Curated and kept fresh on the server — the lineup updates without an app update.
Vision, reasoning, tool-calling and PDF capabilities are labeled on every model. Open-weight models are clearly badged.
Responses render with proper headings, lists and syntax-highlighted code blocks — copy any snippet with a tap. The reasoning trace is one tap away when you want to see how the model got there.
// Format large numbers compactly
function formatNumber(num) {
if (num >= 1e6) return (num / 1e6).toFixed(1) + 'M';
if (num >= 1e3) return (num / 1e3).toFixed(1) + 'K';
return num.toString();
