Wikilinker

Wikilinker automatically adds Wikipedia links to the people, places, organizations, and other notable names mentioned in any webpage. Each name is linked only on its first occurrence, keeping the reading experience clean.

How it works: Wikilinker scans article text for proper nouns and acronyms, matches them against a bundled bloom filter of the top 1,000,000 Wikipedia titles (ranked by pageviews), and adds unobtrusive links directly in the page. Everything happens locally on your device — no API calls, no external requests, no logging.

Features:
- 1,000,000 names in a bloom filter bundled locally (under 2MB) — no network requests
- First-occurrence-only linking keeps articles readable
- Smart filtering avoids false positives on common words
- One-click enable/disable from the toolbar
- Works on any website, optimised for 19 major news sites

Completely self-contained. No data collection, no analytics, no tracking, no accounts. The only stored value is your enabled/disabled preference.
