TinyStudio is a free, easy-to-use, AI-powered automatic subtitle generation Mac app. TinyStudio works with OpenAI’s open-source model called “Whisper.” And To implement the specific function, TinyStudio uses the open-source “whisper.cpp” from Georgi Gerganov. Therefore, to use it, you need to download the model files beforehand. You can either click the “Download” button when starting to generate subtitles for the first time, or you can manually download them yourself.
