About SmartLeaks

News articles change after they're published. Headlines get softened. Details get buried. Entire articles disappear. It happens every day, and almost no one notices — because there's no record.

When a newspaper printed a retraction, it was visible. When a Wikipedia article changes, the edit history is public. But when a news article is silently revised online, the original version simply ceases to exist.

SmartLeaks watches. When you add a source to an investigation, we capture a snapshot and start monitoring. When the article changes, we capture the new version and compute a precise diff. AI-powered analysis separates routine copy edits from meaningful narrative shifts — so you see the changes that actually matter.

Articles undergo 20+ revisions in half a day.
Readers see none of them.— Fass & Main, Digital Journalism

SmartLeaks is not a conspiracy platform. Every finding links to a source. Changes are shown as raw diffs — additions, deletions, modifications — not interpretations. We're not anti-journalist. Editing is normal, and transparency makes it better for everyone. We don't tell you what to think. We show you what changed.

Archives preserve the past. SmartLeaks watches the present.
