in the editing workflow — not a one-off tool
I’m an AI skeptic, and this is probably the first positive use case I’ve found for the technology. We use real human editors through our whole process, and when we’re done, Galley makes sure we didn’t miss anything. We probably averaged one correction every 20 articles before Galley, and now it’s more like one correction every 70 or 80 articles. It made a real difference.”

Why not just paste it into ChatGPT?

Galley learns from you

Feedback on Galley's output improves the model for everyone in your newsroom.

Upload your own sources

Galley checks claims against your own uploaded source material — transcripts, filings, and datasets — uploaded to your private vault.

Purpose-built for news

Galley uses a team of agents trained and tuned for fact-checking, not a general system prompt.

A citation on every claim

Every flag links directly to the evidence behind it — live web sources you can click into and read, not "as of my last update."

Check AP style and house style

Galley checks style, too. You can use the built-in AP stylebook or use your own custom house style.

Native to Google Docs

Galley works where you work. No copy and pasting needed.

Stop errors before they're published.

Sign in with Google and check your first story in a couple of minutes. No credit card required.
