HistoryRewritten

See how the Wikipedia article you're reading changed around a major event — activity score, evidence, exact diffs.

Wikipedia articles change — and after major world events, some of them change a lot. HistoryRewritten shows you, in one click, whether the article you're reading saw unusual editing after an event, and exactly what changed in the text. HOW IT WORKS Open any Wikipedia article and click the toolbar icon. The extension auto-matches a relevant event from the article's own text (October 7, 2023 · the invasion of Ukraine · the release of ChatGPT · the COVID-19 pandemic — switchable per page, with your own default), then shows: • An activity score (0–100) measuring the article's editing against its own 36-month pre-event baseline — edit rate, text churn, revert-like edits, talk-page debate, and editor concentration, computed with robust statistics, no AI involved. • A one-glance verdict chip on the article itself and a toolbar badge (both optional). • One click to the full report: an interactive edit timeline, a transparent score breakdown you can reconstruct by hand, and an on-demand comparison of the last pre-event revision against today's article — exact before/after excerpts, every finding tied to validated evidence, linked to the official Wikipedia diff. WHAT IT WILL NOT TELL YOU Activity is not proof of bias or misconduct. An edit spike can mean new sources, cleanup, disputes, or plain attention. HistoryRewritten shows the measurements and the exact text changes; the conclusion stays yours. Articles with thin history say "insufficient baseline" instead of pretending to a verdict, and the tool never profiles individual editors — aggregate statistics only. PRIVACY Keyword matching runs entirely in your browser. An article's title (plus language edition and event date — nothing else) is sent to the HistoryRewritten service only when the article matches a tracked event and alerts are enabled, or when you open the popup to request an analysis. In silent mode, nothing is sent until you open the popup. No browsing history, no accounts, no tracking. Full policy: https://historyrewritten.org/privacy Works on every Wikipedia language edition (automatic event matching currently reads English keywords; on other editions, open the popup to analyze any article).
