AI thumbnail maker for YouTube. Paste a video link: it reads the title and the current thumbnail, writes three angles, then generates the thumbnail with the text drawn as typed, read back, and graded at feed size. Correct it in a sentence, make three to A/B test on YouTube, run batches of ten videos, or call it from Claude, ChatGPT and the API. One free watermarked preview per account, plans from $12 a month, six languages.
