SpeakShift: Offline media converter + Whisper transcription desktop app (Windows/macOS/Linux)

[AstonWilliams]

Hi everyone,

A big thank you to @ggerganov and the ggml-org team for building and maintaining whisper.cpp — an outstanding open-source project.
SpeakShift is a mature, rigorously tested desktop application that combines fast local media conversion with powerful Whisper transcription in one privacy-focused tool.

Core features:

• 100% offline media conversion (video/audio with FFmpeg control)
• Local Whisper transcription (tiny to large-v3-turbo models)
• Clean library for managing files and transcripts
• Works fully offline on Windows, macOS (Apple Silicon optimized), and Linux

The free version includes full media conversion, basic transcription, library, and all core whisper.cpp capabilities.

Since whisper.cpp is 100% open source and free, the foundation of SpeakShift remains freely available to everyone.

The Pro version (one-time purchase) adds batch processing, speaker diarization (up to 4 speakers), translation, and advanced exports.

I’d really appreciate any bug reports, feedback, or suggestions from the community. Feel free to share your experience or ideas in the comments.
Thanks again to the whisper.cpp team!
