About this extension
WikiLens turns every page into an encyclopedia. Select any text — if it's the exact title of a Wikipedia article, a small popup appears right where you are, with the article's images, its full first paragraph, and a link to read the rest on Wikipedia.

Exact by default. Previews appear only when your selection is precisely an article title, so the popup never gets in your way. Ambiguous titles show a tidy "may refer to:" list of meanings, and one setting also resolves redirects like "USA" → "United States".

23 languages. Point WikiLens at any major Wikipedia edition — with an automatic English fallback when a title only exists there.

Yours to shape. Three popup sizes — Large adds quick facts from the article's infobox (born, occupation, population and the like), each a clickable link of its own. Light, dark, and auto themes. An optional Alt+select trigger and a per-site disable list keep it quiet when you want.

More than one image? Flip through the article's photos without leaving the popup.

Toolbar popup. Your recent lookups at hand, plus a search box for looking up titles directly.

Private by design. Your selection travels to Wikipedia's API and nowhere else. No analytics, no tracking, no accounts. Recent lookups are stored only on your device. Open source: https://github.com/Ville-Mattila/wikilens
