How this is scored

Publishes a price: You can find out what it costs without signing up
Has a privacy policy: There is a document at all, for a product that reads your messages
Says whether it trains on you: States plainly whether your conversations train a model
Addresses people who never signed up: Says what happens to the data of others in your threads
Says what happens if you cancel: States whether your history is kept or deleted
Names who carries the messages: Names the company that actually holds your texts
Names its model providers: Says which AI companies see your conversations
Says where to report a bug: A researcher who finds a hole has somewhere to send it
Says how you start: You can tell what is required of you before you begin

Fewest steps before it does anything

Counted the same way as the onboarding ladder: joining a thread you are already in is zero, texting a number is one, installing an app before you can begin is four. Agents behind a waitlist or an invite are left out rather than ranked last, because unavailable is not the same as high friction.
