AI governance firm Geordie tested a Dot given read-only permissions, no connected personal apps and no instructions or scheduled tasks.

The AI Science rebuilt my gene check report in 15 minutes
A researcher had slowly built his own pipeline to check which parts of a human gene model are backed by real evidence, then still had to judge the evidence by hand.
