What Duckbill does with your messages

Whose hands it passes through

Somebody carries the message, somebody runs the model that reads it, and where the agent uses a website on your behalf somebody operates that browser. A blank below is not an absence of a company, it is a company nobody has named.

Silence is not a denial and it is not a promise. A document that does not address the people in your group thread has not agreed to anything about them.

How old this document is

Duckbill last revised it on 2024-12-04, which was 668 days before we read it. 71 of the 79 policies here carry a revision date at all; the rest do not say when they were last changed, so there is no way to tell whether they describe the product as it ships today.

We have read it 3 times and it has changed 2 times since we started watching, most recently on 2026-10-03. What changed, sentence by sentence.
