I started this project because I was frustrated with existing screen recorders — either they required a subscription, sent my audio to the cloud for captions, or needed a separate editor for basic trimming.
I wanted something simple: record, add AI captions offline, trim, and export — all in one app without touching the internet.
The AI captioning uses Whisper locally, so your audio never leaves your machine. This was important to me for privacy, but also because it works without an internet connection.
Happy to answer any questions about the technical implementation or take feature requests!
