Show HN: Web Video editor, 100% local, AI subtitle, auto cut based on volume

I made this mostly to make content creation faster.

When recording a youtube video/ podcast. there's alot of downtime (silence) while looking at scripts or getting the correct item to display. So I made a webapp to automatically cut and stich the video back together then I can further edit in davinci resolve.

But I recently found out that this is crazy good for rewatching lectures or meeting recordings, No need to render, just drop the video in and watch it right away.

30min lecture can be watched in 12min!

I even added auto generation of subtitles to make studying lecture /meeting better.

Best of all everything runs locally, even the AI is running local models.

Hope HN finds this useful like it did for me!

    Cool service, difficult to use website. On my iPhone random videos kept full screening as i scrolled down and the site was almost unreadable with Firefox dark mode on (I’m reading at night).

    If it's 100% private as you state n your website, it would be opensource.

    I'm a bit confused, why is this 100% local web video editor asking for a login when exporting a video?

    Hey, I've built a very similar tool aimed at creating shorts! Would love to potentially collaborate.

    Is this lossless? Or does it re-encode the video (resulting in a loss of quality)?
