Make it your own.

Yihu is currently available as source code. Build it for your iPhone and connect the services you already own.

Before you begin

• An iPhone running iOS 18 or later.
• A Mac with Xcode, the iOS 18 SDK or newer, Swift 6 and XcodeGen.
• Your own Apple signing configuration and unique App Group identifiers.
• A trusted HTTPS workbench that your iPhone can reach.

Build, connect, then speak

1. Get the source and follow the repository’s build instructions. Configure your identifiers and signing locally.
2. Open Yihu and enter your workbench’s origin, for example https://workbench.example.com. Do not include a path or query.
3. For speech, download the compatible model in the app and grant microphone permission when you choose to record.
4. Transcribe a short sentence, review the text and insert it into a compatible draft editor. Yihu never presses Send.

Native enhancements depend on your service

Opening a web workbench does not certify native integration. Notifications and Live Activities need compatible interfaces and services; Watch features need a paired phone and have separate device checks.

Yihu is independent of Collie, OpenClaw and Hermes. It does not supply a hosted Agent, server, model service or App Store binary.
