Unlimited free video caption generator (no login)

Hacker News

Hi HN, I built a small browser-based tool that generates video captions/subtitles directly in the browser. Most caption tools I tried were either paid per export, limited usage, or required signing up. I wanted something I could use quickly without friction. What it does: Auto-generates captions from video Unlimited exports No login or account Runs in the browser Free to use It’s part of a broader creative toolkit, but this post is specifically about the caption generator. Link: https://www.tsarr.in/captions I’d appreciate feedback on: Accuracy vs existing caption tools Performance on longer videos Features that would make this actually useful for your workflow Happy to answer questions.
