The tool automatically cuts chapters, pauses at checkpoints, and offers six question types, with per-concept progress tracking and a final boss-fight for coding videos. Users can paste a link from YouTube, Vimeo, or direct .mp4, and the AI builds the course in 60 seconds, with a free tier for videos up to 30 minutes.", "body_md": "# Don't rewatch.\n\nTrain.\n\nAI turns any educational video into a course: questions inside the player, wrong answers rewind to the exact spot.\n\nCheckpoint. What does this print?\n\n`log(\"1\"); setTimeout(() => log(\"2\")); log(\"3\");`\n\n## Not a player. A trainer.\n\n### The video asks the questions\n\nChapters get cut automatically. The player pauses itself at checkpoints. You never decide when to test yourself.\n\n### Six ways to ask\n\nThe player never repeats itself twice in a row.\n\n### Rewind to the eureka moment\n\nAI finds the exact 30-second segment instead of saying «watch it again».\n\n### Chapters unlock like a map\n\nWeak answers hide what's next, strong ones unlock an insider take.\n\n### Per-concept progress\n\nNot «53% of the course»: useEffect 30%, useMemo 80%.\n\n### A boss-fight at the end\n\nCoding videos end in a browser editor with Jest tests: no pass without green. Everything else gets a final exam graded by AI.\n\n`8 tests passed`\n\n## Three steps from link to course\n\n- 1\n### Paste a link\n\nYouTube, Vimeo, direct .mp4. Captions or not: Whisper picks up videos up to 140 min.\n\n- 2\n### AI builds the course in 60s\n\nChapters, varied checkpoints, secret branches, a final boss-fight.\n\n- 3\n### Learn and see your gaps\n\nPlayer pauses on questions. Wrong answers rewind. A health bar shows where you're weak.\n\n## Ready to learn the way they should've taught from day one?\n\nPaste a link, get a course, start training for free. Upgrade when you outgrow 30-minute videos.", "url": "https://wpnews.pro/news/show-hn-viddojo-turn-any-youtube-video-into-an-interactive-course", "canonical_source": "https://viddojo.com", "published_at": "2026-07-21 12:06:24+00:00", "updated_at": "2026-07-21 12:22:54.042425+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-tools", "generative-ai"], "entities": ["VidDojo", "YouTube", "Vimeo", "Whisper", "Jest"], "alternates": {"html": "https://wpnews.pro/news/show-hn-viddojo-turn-any-youtube-video-into-an-interactive-course", "markdown": "https://wpnews.pro/news/show-hn-viddojo-turn-any-youtube-video-into-an-interactive-course.md", "text": "https://wpnews.pro/news/show-hn-viddojo-turn-any-youtube-video-into-an-interactive-course.txt", "jsonld": "https://wpnews.pro/news/show-hn-viddojo-turn-any-youtube-video-into-an-interactive-course.jsonld"}}
