SixCut 16:9 · Chapters · Research-first

AI editor for long-form YouTube videos

Long videos are where research and pacing matter most, and where editing takes the longest. SixCut researches your topic on the live web, writes a sourced script, voices it and edits a full 16:9 YouTube video with chapters, b-roll, captions, sound effects and music.

Why long-form is different

A ten-minute video needs a structure that holds attention: an opening that makes a promise, sections that pay it off, and visuals that change often enough that nobody clicks away. It also needs facts that survive the comments section. That's hours of research and editing for every upload.

How SixCut handles it

  1. Research first. It searches the live web and writes a script that lists its sources, with claims checked.
  2. Structure. The video is split into clear chapters, and the publish pack includes chapter timestamps for your description.
  3. Voice and edit. AI voiceover or your own recording, then b-roll, images, graphics, captions, sound effects and music.
  4. Notes on one moment. Point at the part that drags and say what to change; the rest of the video stays as it is.
  5. Ready to upload. A title, description and tags written for YouTube.

One channel, both formats

Turn the same research into a long video and a set of Shorts that point back to it. Both formats use the same channel style, so viewers recognise you either way.

Questions

How long can a video be?

Long enough for a typical YouTube explainer or documentary-style upload. Longer videos simply take the computer longer to render.

Can I edit the script before it's voiced?

Yes. You pick from the scripts SixCut writes, and you can change the wording before the voiceover is made.

Does it work for any topic?

Yes, any niche. The research step is built for topics where facts matter: history, science, money, tech, news and true crime.

What does it cost?

A free trial (3 videos in 7 days), then $12 a month with your own AI keys, $39 a month with the AI included, or $99 a month for Studio (copy any video's style, Pro mode). Yearly billing gives 2 months free, and waitlist members pay less on monthly plans.
