Hey Product Hunt! 👋

I built YakPhone because every SIP app I tried either looked like it was made in 2009 or required sending my calls through someone else's cloud.

The thing I'm most proud of: all AI runs on your device. Whisper transcribes your calls locally. The LLM chat (llama.cpp) never phones home. Your conversations stay yours.

A few things that were fun to build:

Wrapping a C-based SIP stack (baresip) cleanly into a modern SwiftUI app with CallKit
Getting Whisper + llama.cpp running efficiently on iPhone — real-time transcription without killing the battery
The draggable PiP video window that lets you swap local/remote views mid-call
Would love feedback from the community — especially from anyone running Asterisk, FreeSWITCH, or 3CX who wants to test it against their own server.

Happy to answer any technical questions! 🙏

We have released some redemption codes. You are welcome to try them out:
