Screenshot any content or highlight any text — and AI instantly verifies it with real-time web search and cited sources. No subscriptions. No sign-ups. Free forever.
A three-pass AI pipeline that reads any claim, searches the live web, and returns a verdict — all in seconds.
Click the extension icon and drag to select any area on screen — images, headlines, tweets, video captions. Or highlight any text and right-click → "Fact-check this."
Gemini AI extracts the verifiable claim, then uses Google's live search index to find evidence across news outlets, fact-checkers, and Reddit — in real time.
A structured verdict with a confidence percentage and clickable source links appears directly next to your selection — so you never lose context.
Most fact-checkers give you a binary answer. We give you the full picture.
Multiple credible sources confirm the claim with strong consensus.
Research clearly and directly contradicts what the claim states.
Technically grounded but missing context that changes the meaning.
Evidence is insufficient or conflicting. We never guess or fabricate.
Most fact-checkers only check pre-indexed claims. This one searches live, every time.
Drag to select any area on screen — images, tweets, charts, video screenshots, headlines. If you can see it, you can fact-check it.
Powered by Gemini's built-in Google Search. No separate API. Searches live news, independent fact-checkers, and Reddit discussions.
A three-pass pipeline — claim extraction, grounded search, verdict rendering — all orchestrated in parallel for minimal latency.
Every verdict includes a 0–100% confidence score reflecting the quality and consensus of evidence found — not just the AI's opinion.
Clickable source chips with domain attribution accompany every verdict. See exactly where the AI found its evidence.

Because this extension ships outside the Chrome Web Store, you install it in Developer Mode — a standard, safe, built-in browser feature supported by all Chromium browsers. This is how developers and power-users have always sideloaded trusted extensions.
Download & unzip
Click the button above. Save and unzip the file to a permanent folder — Chrome needs the folder to stay there.
Enable Developer Mode
Open your browser's extension manager: chrome://extensions (Chrome/Brave/Opera) or edge://extensions (Edge). Toggle Developer mode on — it's the switch in the top-right corner.
Click "Load unpacked"
Click Load unpacked and select the unzipped folder. FactChecker AI will appear instantly.
Add your API key
Click the extension icon → open Settings → paste your free Gemini API key. You're done.
