About
HN.watch is a demo site built by Scrimba that automatically generates a short, AI-narrated explainer video for a linked article the first time someone clicks it, using Scrimba's HTML-based 'Scrimba Explain' video format instead of pixel-based rendering. It functions like Hacker News but with generated videos in place of articles, produced in a few seconds at roughly $0.04 in generation cost per video.
At a glance
HN.watch mirrors the Hacker News front page and adds an inline Scrimba Explain viewer. It is worth a quick look if you prefer a visual preview, though the tested story did not produce a playable explainer.
Good fit
Hacker News readers who want to try a visual introduction while keeping the source article and discussion one click away.
Consider something else when
Use the article and discussion directly if you need dependable access, original wording or a source you can cite.
Start here
Open a story title to expand its player. If it lands on a course creation screen, use the adjacent article or comments link to keep reading.
Cost and requirements
The feed opened without a login or payment prompt. The tested embed loaded from Scrimba, and the site offered an optional analytics setting that was off during the trial.
Limits to know
The selected story displayed Scrimba’s course creator in its player instead of playing the explainer. Other stories, playback quality and summary accuracy remain unverified.
Why it made the leaderboard
Demonstrates HTML-based AI video generation that costs about $0.04 and takes seconds, showing a viable alternative to slow, expensive diffusion video for explainer content.
