a stronger hook.

A score and useful feedback in about 10 seconds. No account needed to try.
Three steps, about a minute.
Nothing to install and nothing to configure. The browser extension is optional — it just saves you the copy-paste.
Paste your title or thumbnail

Get scored, not guessed at
The engine rates click-through potential, emotion and curiosity, then names the specific words and choices costing you clicks.
Publish the winner
Pick from the rewrites and thumbnail concepts, publish, and track what the change actually did to your CTR.
Make the subject stand out.
A thumbnail concept for a Minecraft aquarium video: a closer subject, brighter contrast, and a short, readable hook.

The scene takes the spotlight; the creature is easy to miss.

A clear focal point and two-word hook make the idea easier to read.
Design comparison only. No measured increase in clicks or views is claimed. Always match the thumbnail to what your video delivers.
Get feedback on your own thumbnailOptimize anything people click.
Creators, marketers, bloggers, newsletters and agencies — one toolkit for everything you publish, laid out by the plan it comes with.
Free, and actually free.
No trial clock, no card on file, nothing that quietly starts charging you. Upgrade only when ten analyses a month stops being enough.
Full analyses every month
Not a preview — the whole report each time: score, weaknesses, five rewrites, thumbnail concepts, keywords and the audience the title will pull. The count resets every month.
No card on the free plan
You never enter payment details to sign up, and nothing upgrades itself. Paid plans start at $7.99/mo if and when you decide you want one.
Name, email, password
That is the entire form. Your data is encrypted in transit and never sold, ad measurement only runs if you allow it, and you can delete the account and everything in it from your profile at any time.
