Will this thumbnail earn the click?

Upload a YouTube or social thumbnail and get a click-readiness read — face & emotion, big readable text, contrast, curiosity and focal clarity — judged as it's seen: small, on a phone. Pick your niche (gaming, vlog, education, finance, beauty, news) and the scoring reweights to what actually earns the click there. It assesses what's in the image; it never predicts a fake CTR.
