Show HN: Unlimited free video caption generator (no login)

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.

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.
