HookLab reads your channel's private analytics and shows you the exact moment people left. It is the number YouTube only shows buried in Studio, and that no tool working from public data can give you.
Anyone can see how many views your video got. Only you can see when people left — and until now, only buried inside YouTube Studio.
Retention curve of a video: what share of your audience was still watching at each moment.
Not "your retention could be better". A specific stretch: you lost 33% of your audience between 0:04 and 0:08. You can open the video and see what happens there.
When a stretch gets watched more than once, audience goes above 100%. That is people rewinding, or the video looping: it tells you what to repeat, not only what to fix.
YouTube works out how your retention performs against videos of similar length. When that number exists we show it as it comes; when it does not, we do not approximate it.
Requires connecting your YouTube analytics with a read-only permission. The rest of HookLab works without it.
The diagnosis tells you where to look. This is what comes next.
Find videos that broke 2.5x your channel's average — yours or any competitor's. One click → Studio with that title preloaded as your seed. From insight to script in seconds.
5 concrete ideas with title, hook and suggested thumbnail, tailored to your channel by Claude. They come ranked from most to least promising within that batch — a relative order among the five, not a view prediction.
Full script in seconds, 3 alternative title angles auto-generated, and 4 AI-generated thumbnails per click. The A/B ranks your titles against each other and explains each position. All in one panel — Claude + Flux.
We recommend the top 2-3 tools (HeyGen, Runway, Sora, Descript…) for each type of video. No lock-in, no surprises.
We would rather you know what can be measured before you find out the hard way.
CTR and impressions are not in the YouTube API: they only exist inside Studio. We could estimate them from other numbers, but it would be a made-up figure that looks like data, and you would make decisions with it.
Nobody knows how many views a video will get before it goes out. If a tool hands you a specific number, it is making it up — and so would we if we handed you one.
We can measure that you lost audience at second 38. Why they left is something you know when you watch that moment: you know your video, your topic and your audience. We have seen none of the three.
Four reasons that won't change tomorrow, no matter what any competitor ships next.
