FactChecker Pro is the Chrome and Edge extension that detects misinformation in real time. Credibility scores, AI claim detection, deepfake alerts, Social Media Shield, and now FactPlay and Election Watch NL. Running silently on every page you browse, and on your Windows desktop.
- Where: Hogeschool Utrecht, Padualaan 101, Utrecht. Look for the FactChecker Pro stand at the Green Market expo on Monday 29 September 2026.
- Try it hands on: play unlimited rounds of Spot the Fake, explore the Election Watch NL pilot, and test the extension and desktop app on live pages with the team.
- Tell us what you think: a two minute feedback survey at the stand gives you a say in what we build next. Fill it in ahead of time →
- FactPlay — A new gamified hub with seven tools: a daily Spot the Fake challenge, Live Event fact-check rail, Viral Radar, Screenshot Check with reverse image search, Creator Credibility lookup, Job Offer Check for scam red flags, and Squad Mode private leaderboards.
- Election Watch NL — A pilot built with Dutch election disinformation researchers. Election claims fact-checked in Dutch, side by side with NL news on the same topic, sourced from Dutch language fact-checkers rather than machine translated.
- FactNews — The news feed has been redesigned as a scrolling feed with a debunked claims rail and a search box for social and topic claims, so you can check what is being said about any subject in one place.
- Right click to fact-check — Highlight any claim on a page, right click, and get a fact-check result without opening the dashboard.
- Dutch language — Nederlands joins English, French, German, Spanish and Italian in the dashboard and desktop hub, with a language switch in the sidebar.
- Seasonal misinformation tips — A side panel with practical tips on the scams and false claims that spike around holidays and major events.

We asked early users to give us honest feedback — no script, no prompts, just what they noticed using the extension in their daily browsing.
Installed FactcheckerPro from the Chrome Web Store — one click, no warnings, fully trusted. It correctly flagged a known false claim about election fraud on X. The pop-up rating appeared within 2 seconds.
A friendly fact-checking system between the beacons could help improve overall accuracy since it incentivises doing double checks. Keep a friendly mistake culture — punishing people who give wrong facts does not help.
The extension works cleanly and the credibility indicators are clear. A translation option would make this even more powerful — misinformation is not just an English-language problem. It is a global one.
