Turn any BJJ video into focused techniques. Trained on the vocabulary of BJJ.
Works with YouTube, TikTok, and Instagram. Each video becomes a card: techniques broken into steps, concepts distilled. The notes you'd take if you had time, in a searchable library you can pull up before training. Thousands of techniques extracted and counting.
What you get back
Tap any step. Jump to that moment.
ZenCub finds every technique in the video, names it, breaks it into steps, and timestamps every step back to the second it happens. Watch alongside the notes, or skip the watching and tap straight into the steps you need.
Coach's tip — tap Extract to see what comes back.
This is the public share view. In your library you also get notes, edits, stack grouping, and search across everything you've ever saved.
The watch-and-forget loop
Saved to Watch Later. Bookmarked on Instagram. Forgotten by Saturday.
And once you have a few
Group them. Stack them. Pull them up before training.
Cards don't just sit in a flat list. Group them into stacks — “Comp prep — NAGA April,” “Closed guard game,” “Submission chains.” Reorder, share with a teammate, scroll one before warmups.
No subscription
Pay once. Use them whenever.
Library, search, stacks, edits, and sharing are free forever. Credits are only spent when you import a new video. New accounts start with 5 free credits.
No monthly fee. No auto-renewal. No expiring credits.

In one paragraph
What is ZenCub?
ZenCub is a Brazilian Jiu-Jitsu (BJJ) technique organizer. Paste any YouTube, TikTok, or Instagram link and ZenCub identifies each technique in the video, names it, breaks it into 4–8 numbered steps with timestamps, and tags it by position, technique type, gi/no-gi, and instructor. Cards live in a searchable personal library. New accounts get 5 free imports; additional imports use credit packs that never expire. No subscription.
Questions
The ones we get most often.
What comes back when I paste a video?+
A card with the technique named (kimura, deep half sweep, knee cut), the position and type tagged, and the breakdown condensed into 4–8 numbered steps you can scan in under a minute. Every step is linked back to the exact moment in the source clip — tap to jump there. If something's off, rename it, change the position or type, adjust the tags; your edits become the canonical version in your library.
What kinds of videos work?+
Any public YouTube, TikTok, or Instagram link — short clip, 40-minute breakdown, gi or no-gi, fundamentals through advanced. Each card gets tagged automatically with position, technique type, and ruleset.
Why not just save it on YouTube or bookmark it on Instagram?+
Because those saves go nowhere. Watch Later becomes a 200-video graveyard. Saved Reels vanish into the algorithm. By Tuesday open mat you're scrolling bookmarks for "the kimura one" — and you give up. ZenCub gives every saved video a card in a searchable library, tagged by position, type, gi/no-gi, and instructor. Type "Lachlan Giles" and every clip you've ever saved from him is one tap away.
How much does it cost?+
Every account starts with 5 free imports. After that, credit packs start at a few dollars and never expire — no subscription, no auto-renewal. Library, search, stacks, and sharing stay free forever.
What if I run out of credits or stop using it?+
Nothing breaks. Your library, stacks, edits, and notes are yours — credits only gate new imports, and the cost is shown before you spend one. Unused credits stay in your account forever.
Is there an iOS app?+
A native iOS app is in the works. In the meantime, ZenCub runs as a full installable web app — open zencub.com in Safari, tap Share → Add to Home Screen, and it launches like any other app, full-screen, with offline access to your library. Everything works the same on desktop and Android too.
Can I share a card with my training partners?+
Yes. Every card and every imported video has a public share link they can view without an account. If they want to save it to their own library, that costs them one credit.
What if a technique name or position is wrong?+
Every card is editable. Rename the technique, change the position or type, adjust the tags. Your edits become the canonical version in your library and on any share link you send.
Does it recognize specific instructors like Lachlan Giles, Gordon Ryan, or John Danaher?+
Yes. Instructors are auto-tagged when they're identifiable from the video. Type a name in your library and pull every saved card from that instructor in one tap.
Does it work for gi and no-gi?+
Both. Each card is tagged gi, no-gi, or either based on what's actually in the video — grips, attire, and what the instructor says.
How long does an import take?+
YouTube imports are fast. TikTok and Instagram take a little longer because the spoken instruction needs to be processed. You'll see live progress while it runs.
Does it work for wrestling, judo, or MMA videos?+
ZenCub is built for BJJ. Adjacent grappling content (wrestling, judo, sub-only) often works, but technique recognition and tagging are tuned to BJJ vocabulary and positions.
5 free imports. No card required.
