Three layers, one verdict

capture · analyse · verdict
01 · capture

Paste text or click any image

Right-click context menu, popup paste box, or one-click image picker that overlays any page. The extension redraws each image into a canvas so cross-origin servers don't block the check.

02 · analyse

AI analyses + extracts claims

Backend calls OpenAI Vision (for images) and a strict-JSON GPT prompt (for text). The model checks internal consistency, sensational phrasing, fabricated-sounding numbers, AI-generation tells.

03 · verdict

Verdict + confidence + suggestions

One of: likely authentic / mixed / suspicious / likely fake / unclear — plus a confidence number and a short list of concrete claims a careful reader should re-verify with a primary source.
