Title + thumbnail brief your editor can execute

What you need: The video itself in summarized form — a rough cut description, a transcript paste, or 5-10 talking-point bullets covering what happens in the video. The promise the video makes (what the viewer learns or sees). One sentence on your channel's niche so the AI can match the title voice. Your current average CTR on similar videos if you know it (helps calibrate the hypothesis); skip if you don't.

How to use: If you've built your business profile (see "Start here") and saved it as a Claude Project / Custom GPT / Gemini Gem, open that and paste this prompt inside — the AI will skip the channel-niche question. Otherwise paste into any fresh AI chat. The AI interviews you across 5 questions, then produces a brief your editor or designer can execute on without follow-up questions: the "this video is FOR" line, 5 title options (one per CTR pattern — curiosity, number, vs, personal-stake, mystery) with mobile-truncation notes, 3 thumbnail concepts with visual hierarchy spelled out (subject, text, color, contrast), and a CTR hypothesis per recommended pairing. Send the brief verbatim to your editor — the specific numbers and pairings are load-bearing.
