All ToolsGenerate 10 click-worthy title variants and a full SEO description for any video topic. Runs on-device with Chrome's Gemini Nano — your topic never leaves your browser, zero API cost.
Your YouTube title and description do more work than anything else in the algorithm — they determine who clicks, who stays, and who YouTube shows the video to. This tool uses Chrome's on-device AI (Gemini Nano) to generate 10 title variants across proven patterns (numbers, curiosity gaps, front-loaded keywords, specificity) and a full SEO description with keyword placement, hooks, and structure. Nothing leaves your browser. Zero API cost.
The tool uses Chrome's built-in Gemini Nano AI to generate 10 title variants and a full SEO-optimized description. Titles follow proven YouTube hook patterns — numbers, brackets, curiosity gaps, specificity. Descriptions include target keywords, timestamps structure, and CTAs.
Under 60 characters (so it doesn't get cut off), front-loads the keyword, triggers curiosity without clickbait, includes specificity (numbers, years, exact results), and matches search intent. The AI generates variations across all these patterns.
No. The AI runs 100% on-device via Chrome's Gemini Nano model. Your topic, keywords, and generated output never leave your computer. That's also why there's zero cost — no API calls, no server-side processing.
Latest Chrome (and Chromium-based browsers like Edge, Brave, Arc) with Gemini Nano enabled. First use downloads the ~1.5GB model. If you see a "not supported" warning, update Chrome or try a different browser — Firefox and Safari don't yet support the LanguageModel API.
