I've quietly shipped something I'm quite pleased with: Wikilinker, a browser extension that auto-links the top 1,000,000 Wikipedia names on any webpage you visit.

It's a modern rebuild of the Wikiproxy I hacked together in 2004 — same idea, much better execution. The extension runs entirely in your browser, makes no API calls, and uses a bloom filter to pack a million Wikipedia titles into under 2MB.

Available for Chrome, Firefox, and Safari (macOS and iOS). You can also see how it works by trying this Guardian interview with Jimmy Wales through the proxy. Full details on the Wikilinker about page.

Yup, I'm another one of those former-developer exec types who started playing with Claude Code at Christmas.
