How to study
Survey overview → intuitive analogy → detailed model diagram → mathematics and tensor shapes → runnable PyTorch → interactive experiment → spaced repetition. Every analogy should state precisely where it stops being valid. No generic filler animations.
Publishing status: The old 46 lessons remain accessible, but lessons 02–46 still need deep scientific expansion. New roadmap entries are planned unless an actual interactive chapter has been published. A session title is not a completed lesson.

Natural narration
The old browser voice sounded robotic because it used system text-to-speech. The Natural Voice Lab provides an experimental local neural synthesis option using Kokoro in a browser. It also offers system-voice fallback. Long pages and older browsers may synthesize slowly. No API secret is required.
