Shorts only
Stop posting blind. Every short read against your own numbers.
Paste a link. Chumoku watches the video, finds the seconds people left on, and tells you what to cut.

Watched the whole thing
The idea lands, the open does not. You spend 0:00 to 0:03 setting up a payoff the thumbnail already gave away.
Fix
- Cut the first 1.4s. Open on the reaction at 0:03.
- Retention falls off a cliff at 0:07, where the b-roll repeats.
The workspace
Four surfaces, one balance.
No long-form, no podcasts, no everything-app. They share one credit pool, so a week can go wherever the work goes.
Competitors
Only what beat the channel it came from.
Every recent short is measured against that channel's own median views per day. A big channel posting normally stays out.

From the Discord
Not a wall of five stars.
Verbatim messages, one per surface, from people who were using it anyway.
“added 4 competitors yesterday and the tool literally picked out the exact 2 shorts that blew up on their channels lol”
“re-wrote the first 5 seconds based on the prompt, retention actually stayed flat through the intro”
“figured out people were swiping away right when I started doing the sponsor plug... that graph read is insane”

Questions
Before you sign up.
It watches your Short and tells you what to fix. Paste a link, a hook or a script, and you get a score, the exact seconds to change, and a conversation you can keep asking questions in. YouTube Shorts only.
Yes. You get 20 credits when you sign up, with no card. That is about four video reviews, or a lot more if you are checking hooks and scripts. The free credits are one time and do not refill.
No, everything works without it. If you do connect it, Chumoku reads your real retention curve and names the seconds people actually left on, instead of guessing at them. It takes two clicks.
No. YouTube Shorts only, on purpose. That is what lets it point at the second people swiped instead of handing you general advice.
It shows you only the videos that beat the channel they came from. You pick the channels; a small channel's breakout gets in, a big channel's routine upload does not. Finding them is free, and a credit is spent only on the one you open.
Yes, from the billing portal, and you keep everything until the period you already paid for ends. No contract and no call.
