Tools I built because I needed them

Word-by-word karaoke captions for any video, made on your machine.

$ wordcaps burn talk.mp4 --lang en

Transcribes with Whisper, then treats timing as the real problem: silence-aware transcription, word edges snapped to the loudness envelope, and a coverage check that re-reads the finished file and fails if any speech has no caption.

How findable is a website on Google and in AI answer engines?

$ npx geocheck example.com

Audits crawl and index, on-page SEO, AI readiness (10 AI crawlers, JSON-LD entities, quotable answer blocks, llms.txt) and local signals. Every issue is a measurement with the page it was measured on. Zero runtime dependencies.

The gym log I actually use, built for the phone.

Opens on today's workout with last session's weights already filled in. Supersets, history, progress charts and a nudge when it is time to add weight. Works offline; the data never leaves the phone.
