Show HN: Cuto – Turn raw footage into viral shorts in 30s with an AI prompt (opens in new tab)

I built Cuto because I was tired of spending hours on the repetitive parts of video editing: splitting long footage, syncing audio and captions, filtering out bad takes, and adjusting the pacing. I just wanted to focus on the storytelling.

Cuto is an AI video editing workspace that automates the grunt work. You drag and drop up to 12 video clips, write a quick prompt detailing what you want (e.g., "Find the best 30s product highlight and add a strong CTA"), and the engine does the rest.

Within 30 seconds, it hands back an editable visual timeline with: - Auto-split shots and filtered out silences/bad takes - Synchronized captions with rhythm alignment - Selected highlight effects and custom watermark branding - Auto-generated social-ready copy for TikTok, Shorts, and Reels

Unlike traditional NLEs (Non-Linear Editors), we wanted an interface where the visual parameters are controlled intuitively by natural language first, giving you a solid 80% draft instantly. From there, you can still tweak the timeline if needed.

It's currently geared towards talking heads, unboxing videos, reviews, and live stream clips.

I'd love for you to try it out. We still have a lot of edge cases to cover regarding complex scene transitions, but I'd really appreciate any feedback on the UX, the rendering speed, or the AI's editing choices.
