Find out what your next title will actually earn you — a Clks Score out of 100, the words costing you clicks, and five rewrites that fix them.
Titles, headlines, captions, subject lines · Real result in ~10 seconds
Nothing to install and nothing to configure. The browser extension is optional — it just saves you the copy-paste.
Drop in a video title, blog headline or thumbnail — or let the browser extension grab it for you right on YouTube.
The engine rates click-through potential, emotion and curiosity, then names the specific words and choices costing you clicks.
Pick from the rewrites and thumbnail concepts, publish, and track what the change actually did to your CTR.
Both of these ran through the scorer at the top of this page — same engine, same 1–100 scale, scored just now rather than written down by us.
Example titles · scored live, not quoted
Creators, marketers, bloggers, newsletters and agencies — one toolkit for everything you publish, laid out by the plan it comes with.

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.
