Katto
Chrome extension

Clip YouTube videos and Twitch VODs from the video page

Clip with Katto adds a button under every YouTube video and Twitch VOD. Click it and Katto opens with that video ready, no link to copy. Or mark a start and an end while you watch, and Katto renders exactly that moment as one vertical clip.

Under a YouTube video: the Clip with Katto button next to Share and Save, and below it the Clip a moment bar with Start 0:02, End 0:15, Clip this moment and Last 60 s.
The button and the Clip a moment bar, under a YouTube video.

What it adds

Clip with Katto

A button under the player. It opens Katto's create screen with the video filled in: pick your settings and start, as with a pasted link. If you're logged out, the video is still there after you log in or sign up. Shorts are skipped, they're already vertical.

Clip a moment

Press Start and End at the right times while the video plays, then Clip this moment. Katto renders exactly that passage as one vertical clip, captioned and reframed. A moment lasts 5 seconds to 3 minutes and counts as one video of your plan.

Last 60 s

Just watched something worth keeping? One click clips the 60 seconds before the current time.

Any other page

The toolbar icon sends the page you're on to Katto, so it also works for the other sources Katto accepts, like Vimeo, Kick, Loom or Google Drive links.

What it can see

The extension asks for one permission, activeTab: it reads the address of the current tab only when you click its icon. Its button and bar run on youtube.com and twitch.tv only.

It collects no data, sends nothing anywhere, holds no account information and loads no remote code. The Start and End marks stay in the page's memory and are cleared when the video changes. The button is a plain link to katto.tech; your usual Katto session does the rest.

Its labels follow the language YouTube or Twitch is displayed in, in 11 languages.

Questions

Is the extension free?

Yes. It works with every Katto plan, including the free one. Clips use your plan's monthly videos, as they would from the website.

Which browsers does it work in?

Chrome, installed from the Chrome Web Store.

Does it work on Twitch streams?

On VODs, the past broadcasts at twitch.tv/videos/…. A stream that is still live has no fixed video to clip yet.

Why can't I clip more than 3 minutes as a moment?

A moment is meant to become one clip. For a longer passage, use Clip with Katto: Katto then picks the best moments of the whole video.

Do I need to stay on the page while it renders?

No. The job runs on Katto's servers; you can close the tab and find the clips in your dashboard.

Add it to Chrome
