Make lectures watchable in 60 seconds

Long lessons, cut into the moments that stick.

A full lecture is a hard ask on a phone. Katto breaks your teaching down into focused vertical clips, one idea each, reframed with you in shot and captioned accurately, so students can learn a concept in the time it takes to scroll past it.

Why Katto for educators

Accurate captions in 99 languages

Word-level captions are generated automatically and follow the audio, making clips accessible on mute and understandable to non-native speakers. Proper nouns and technical terms are corrected for readability.

Steady reframe that keeps the subject in view

Katto reframes to 9:16 with a calm, tripod-like crop, and letterboxes wide shots or slides instead of cropping the board or diagram out of frame.

The pipeline finds the teachable moment

Virality scoring ranks segments on Hook, Flow, Value, and Trend, surfacing the self-contained explanation worth clipping rather than making you scrub a full lecture.

AI dubbing to reach more learners

Localize a clip into 8 languages with AI dubbing, extending a single lesson to students who don't share your first language.

Publish anywhere, no credit rationing

One-click export or scheduling to 7 platforms, on flat €12/month pricing for 25 videos up to 90 minutes, no per-minute credits to run out of mid-lecture.

How it works

  1. 1

    Add the lecture or class

    Paste a YouTube link or upload the recording of a lecture, course module, or webinar. Long sessions up to 90 minutes are fine.

  2. 2

    Surface the key points

    Katto scores every candidate on Hook, Flow, Value, and Trend, so the concept students actually replay rises to the top of a two-hour class.

  3. 3

    Reframe to vertical, caption in any language

    Clips are reframed to 9:16 with face tracking, and word-level captions in 99 languages are added automatically, so a class reaches students who watch on mute or in another language.

  4. 4

    Refine and publish

    Tweak the crop, captions, or trim in the editor. The preview is the export, so the clip you approve is the clip students see.

Frequently asked questions

Are the captions accurate enough for technical material?

Captions are word-level and the pipeline runs a proper-noun and terminology correction pass, so names and technical terms come out readable. You can also edit any caption in the editor before exporting.

Can I clip a long lecture recording?

Yes, the Creator plan handles videos up to 90 minutes each, and Katto automatically finds and ranks the clippable segments within them.

What does it cost for a course creator?

€12/month billed annually (or €15 monthly) for 25 videos per month, plus a free plan with 2 videos a month to try it.
