A Send to Kindle browser extension that checks its own ePubs

A browser extension made with Claude turns web articles into ePubs, uses an AI agent to check them, and can rewrite its own code when one goes wrong.

The full story

Frustrated with existing extensions for sending online articles to a Kindle as ePubs, the maker built their own with Claude. An AI agent reviews each ePub to make sure the full text and photos make it in and the ads and other junk stay out.

If it does get one wrong, a button sets another AI agent rewriting the code behind the system to fix the problem, which the maker says takes about five minutes. They say it works "flawlessly every time"; for now some of it, including emailing the ePub, runs on their own device.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
