The full story
A music video editor who used to tap out beats by hand to set markers in Premiere Pro wanted something like DaVinci's beat detector. Although not a developer, they built a plugin with Claude Code called BeatMarker. You pick a WAV or MP3 clip and hit Analyze, and it finds the BPM and drops coloured markers on every beat: red on the downbeat, blue on the backbeats and yellow on beat three.
It is a UXP plugin for Windows and macOS that runs in Premiere 2025 and 2026, and it is free and open source. For now it only handles 4/4 time at a steady tempo. Claude also made the download site.
