How this directory works

Every profile has evidence behind it.

The same research standard is applied to every product. We separate vendor claims from independent evidence, record uncertainty, and date every review.

01
Verify the product

We establish the exact product, company, current status, and whether its AI capability has actually shipped.

02
Check primary sources

Features, pricing, providers, privacy, security, and limitations come from current documentation.

03
Look beyond marketing

Independent reviews and recent community discussion add context, with weak signals labeled as weak.

04
Publish the caveats

Every profile names meaningful limitations and records which claims are safe to publish.
