About
Austin's Transcriptor is built by Austin Munday on top of whisper.cpp (the open-source C/C++ port of OpenAI's Whisper) and Gemma 4 (Google DeepMind's open-weight language model). Nothing in this app talks to a server we control.
If you also want a fast, dark-mode weather radar on your iPhone, my other app is Austin's Radar.
