Missing Link

A Wikipedia tool that finds articles which mention a topic by name but don't link to it, then lets you add the missing wikilink directly from your browser.

How it works

1. Enter a Wikipedia article title.
2. The tool searches Wikipedia for articles that mention the title but don't include a wikilink to it.
3. For each candidate, a diff shows the proposed edit in context.
4. Save the edit to Wikipedia with one click (requires a Wikipedia account), or skip to the next candidate.

Redirect targets are handled automatically — if the title is a redirect, the tool produces a piped link (e.g. [[Possession of stolen goods|handling stolen goods]]) and excludes articles that already link to the redirect target.
