About this app

ZenCub turns the BJJ videos you already watch into a searchable library of step-by-step technique cards.

Paste a YouTube, TikTok, or Instagram link and ZenCub automatically breaks the video down into a clean recipe card: the technique name, position, key steps with timestamps, and the details that actually matter — so you can study, remember, and drill what you learned instead of re-scrubbing the video.

WHAT YOU CAN DO

• Import from YouTube, TikTok, and Instagram — paste a link, get a card.

• Auto-extracted steps with timestamps that jump straight to the moment.

• A personal library you can search and filter by position, instructor, and gi / no-gi.

• Stacks — build game plans by grouping techniques by position.

• Explore a growing catalog of breakdowns and save the ones you want.

• Study mode — swipe through steps full-screen with a tappable timeline.

• Add your own notes and tags to any technique.

BUILT FOR GRAPPLERS

ZenCub understands jiu-jitsu: guard, mount, side control, back, half guard, passing, sweeps, submissions, escapes, and more.

HOW IT WORKS

1. Paste a video link.

2. ZenCub transcribes and reads the technique.

3. You get a structured card — steps, positions, timestamps — saved to your library.

New accounts start with free credits so you can try it right away.

What’s new

Fixes in this update:

• Camera-roll imports now survive the app closing mid-import. They finish in the background instead of being lost.
• Portrait videos you import now fill the screen properly, instead of sitting in a short, wide frame.
• Fixed a case where an interrupted import could be finished under the wrong account after switching users.
• Restored the "Analyze anyway" option when a video is flagged as not martial arts.
