Grammarly pretends to provide expert reviews

Upon finding out that Grammarly uses AI-generated editing, supposedly driven by real authors, Casey Newton for Platformer kicked the tires on the fakery.

And there, hovering near the top of the draft, was John Carreyrou, the investigative journalist and bestselling author who took down Theranos. I’d pay good money for advice from the real Carreyrou, whose dogged pursuit of the truth behind Elizabeth Holmes’ company in the face of overwhelming legal threats is the stuff of legend. Alas, the fake Carreyrou conjured by Grammarly offered only the most anodyne of advice.

As Newton points out, plenty (or all) LLMs are driven by data that was slurped up from any available resource. So any generated writing is based on someone else’s, but Grammarly took the extra step of putting real author and writer names against the generated output without asking.

Update Grammarly is now facing a class action lawsuit and shutdown the feature.
