Built a browser extension where Jev decides whether to hide or collapse X posts based on natural-language rules.
The original post
I built a browser extension with Jev @typesafeai that can hide/collapse posts on X based on natural language.

Engagement when collected
Numbers are a snapshot taken from X when the case was added to the library (schema v1, collected 2026-09-19); they will not match today.
Where this case fits
Filed under browser & computer use. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the browser & computer use page.
