What is Bring Your Own AI?
Bring Your Own AI is a native iOS chat client that lets you talk to the world's most capable AI models — OpenAI's GPT-4o, Anthropic's Claude, DeepSeek, and MiniMax — from a single, beautifully designed app.
You bring your own API keys. They are stored in the iOS Keychain with Secure Enclave-backed AES-256 encryption, never transmitted to any server, and never leave your device. We have no servers. There is nothing for us to collect, because nothing ever reaches us.
Why BYO-AI?
- BYOK (Bring Your Own Key). Your API keys live in the iOS Keychain, encrypted with hardware-backed AES-256. We never see them.
- Every model, one app. Switch between GPT-4o, Claude 3.5 Sonnet, DeepSeek-V3, and the MiniMax family — without juggling browser tabs.
- Thinking, visible. Reasoning models (DeepSeek-R1, o1, etc.) expose their chain-of-thought — collapse or expand on demand.
- Streaming Markdown. Watch responses render token by token with full Markdown, LaTeX, and syntax-highlighted code blocks.
- Local-first. Every conversation lives only on your device. AirDrop to back up.
