Structured hook scoring, AI-assisted rewrites, and audience retention insights—built into YouTube Studio for pro creators. ViralHook AI for YouTube Studio helps you tighten hooks, thumbnails, and retention without leaving YouTube Studio. Hook intelligence Analyze your title + opening script + thumbnail text with a clear score, dimension breakdown, and actionable suggestions. Try rewrite modes (shorter, curiosity, specificity) tuned for long-form or Shorts. Thumbnail (new) Get niche-aware on-image text ideas with Suggest & Regenerate. See readability hints (words/length for mobile). Run “Check alignment with title & hook” so your thumbnail promise matches what you actually say. Audience retention (when connected) Connect YouTube to load your retention curve and where viewers drop with coaching aligned to your video. Built for serious creators - clear, professional tone; no clutter. Data you send is used only to generate coaching (see our privacy policy on the backend site). 🔑 Tip: Add channel type + optional niche for sharper thumbnail wording. 📌 Works on https://studio.youtube.com - pin the panel while you edit.
