Segmenter

Free. Runs in your browser.

A two hour recording is useless as one lump. Segmenter chops a lecture, interview or podcast into pieces you can actually work with.

Split by length, or at the quiet gaps between speech.
Download the pieces. Splitting stays entirely on your device.
Optional: add your own OpenRouter key and it'll transcribe the segments too (that part sends audio to OpenRouter).

Why I ask: I might reach out with a question about how to improve this tool, or to mention other cool tools I build. I will never give your email address to anyone else. You only have to do this once per browser.
