The workspace

One clean place for every model

Compare providers without exporting chats or managing a dozen browser tabs.

Switch models mid-conversation

Move from Claude to GPT, Gemini, DeepSeek, GLM, or any OpenAI-compatible endpoint while keeping the thread intact.

Your keys, your account

API credentials stay in the iOS Keychain. Requests go directly to the provider you choose—without an OpenChat relay.

Private by default

Chats live on device. Optional backup uses your own iCloud. No accounts, no tracking SDKs, no telemetry.

Native and fast

Streaming replies, Markdown, search, pinned threads, dictation, and a SwiftUI interface built for touch.

Hermes

Connect with the Hermes service on your Mac

OpenChat Pro generates a one-line start command. Run it in Terminal, and your iPhone connects with your local Hermes tools, memory, and skills.

  • No always-on cloud dashboard
  • Command generated in the app
  • Your Mac stays the boundary for private tools
hermes config set api_server.enabled true && hermes gateway
