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!
It should be mobile friendly now. I did do some quick tests. While the format support on mobile is super limited. It actually runs AI extremely efficient. Crazy how powerful phones gotten these days.
Either way I’m not collecting video information. It’s gonna bankrupt me just on storage fees given how videos are so large
Most important reason is to link membership.
Second is to prevent abuse for some of my features. Think of it like my poor mans recaptcha.
I can see why you were confused. Local in this case really meant there’s no uploading of videos. Render, editing, processing all done on your computer. Which also meant that speed of the app could vary depending on if you use it on your Apple Watch vs gaming pc. Hope that helps!
