My research agent cited example.com
Getting a small on-device model to actually do research, and a ledger that shows exactly what left the device.
PawHub 1.4.0, now completely free
The biggest redesign since launch, every feature unlocked, and an engineering hardening pass before shipping.
I tried to search the web from my own app. It said no.
Storyline 1.2.1: protected names are held back, the query is rewritten on device, and the research still comes back cited.

For Max. For Sky.
A parrot that flew away, a puppy that got into cockroach chalk at midnight, and why PawHub, now CompAnimal, exists.

Private AI is becoming a marketing phrase. For confidential work, privacy has to be something you can check, not something you are told.
