Verdict pills

✗Debunked✗Mostly False~Mixed?Lacks Evidence?Unverifiable~Plausible✓Mostly True✓Confirmed

Each theory in the Conspirafy database is assigned one of these eight verdicts. The extension surfaces the verdict colour and label directly in the page text.

How it works

  1. 1

    Daily lookup sync

    Once a day the extension fetches a ~100 KB compressed theory index from our static CDN. After that, everything runs locally — no server calls per page visit.

  2. 2

    Smart text matching

    A 3-gram fuzzy matcher scans visible text blocks on supported pages. It catches paraphrases: 'did NASA fake the moon landing?' matches the Moon Landing Hoax entry.

  3. 3

    Inline verdict pills

    When a match crosses the confidence threshold, a colour-coded pill appears near the text. Red = debunked, green = confirmed, grey = unverifiable — and every shade between.

  4. 4

    Paste-a-claim popup

    Click the toolbar icon to paste any claim or headline. The popup searches the local index and returns the top matching verdicts with one-click links to the full evidence pages.

Privacy by design

The extension makes exactly one network request per day — to fetch the theory lookup table from our static CDN. That request contains no user identifiers and is not logged against you. All text matching, all search, all verdict display happens locally on your device. We never see which pages you visit, which theories you read, or what you type into the popup search box.
