YouTube AI Chapters

Automatically generates clickable AI chapters for YouTube videos without official chapters, based on the video's transcript.

Tired of scrubbing through long videos to find the part you need? YouTube AI Chapters automatically generates clickable chapters for any YouTube video that doesn't have official ones – right after installation, with zero setup. ⏱️ WHAT IT DOES • Detects videos without official chapters and generates meaningful ones from the video's transcript • Compact, collapsible chapter list below the video – click any chapter to jump right to it • Chapter markers directly in the progress bar, styled like YouTube's native chapters, including chapter titles when hovering • Shows the current chapter while you watch • Export chapters to your clipboard in YouTube description format • Timestamps are always real: every chapter starts at an actual moment from the transcript – the AI never invents times 🤖 AI WITHOUT SETUP The extension automatically picks the best available AI source: 1. Chrome's built-in AI (Gemini Nano) – runs 100% locally in your browser 2. Your own API key (optional): Google Gemini (free key) or Anthropic Claude – best quality and reliability 3. Free cloud AI – anonymous community services, no key needed 4. A local algorithm as a guaranteed fallback – so you always get chapters Chapter titles are generated in the language of the video – the extension works with any language. 🔒 PRIVACY • No user data is collected, tracked or sold – ever • Only the video's public transcript is sent to the selected AI service (nothing at all leaves your device when Chrome's built-in AI or the local algorithm is used) • Your optional API key is stored locally in your browser and sent only to the provider it belongs to ⚙️ SMART BEHAVIOR • Skips videos that already have official chapters • Optionally skips music and very short videos • Chapters are cached per video – regenerate anytime with one click • Status popup shows what the extension is doing on the current tab Open the extension popup to check the status or add an optional API key for the best chapter titles.
