YouTube Retention Curve Checker
Paste the "% still watching" numbers from your video's audience retention graph. You get the biggest drops with timestamps, your 30-second hold, rewatch spikes and an estimate of average % viewed. Nothing is uploaded: it runs in your browser.
Get this for every video, from your real data
Asendify AI connects to YouTube Studio (read-only), reads each video's full retention curve, traffic sources and click-through data, and tells you what to change in your next upload, using Asendify's retention playbook.

Where do I find my retention numbers?
In YouTube Studio open the video, go to Analytics, then Engagement, and hover over the Audience retention graph. Write down the % still watching at a few points (for example every 10% of the video, or every 30 seconds) and paste them here.
What is a good 30-second retention?
There is no single number for every niche and length. As a rule of thumb many long-form videos keep roughly 60 to 75% of viewers at 30 seconds; much lower usually means the opening doesn't confirm the title and thumbnail fast enough. Compare against your own best videos first.
Does this tool connect to my channel?
No. It only uses the numbers you paste and runs entirely in your browser. Asendify AI (the paid app) connects to YouTube read-only and does this for every video automatically, with your real curves.
