What it is
Sift is a Chrome extension that labels every post and reply on X with one of six categories (Substance, Humor, Chit-chat, Promo, Junk, AI-written) plus two flags (AI-written, Off-topic). Users choose which labels to hide, making the feed tech-only by default.
How it uses Jev
Jev decides the label for each post and reply, and the AI-written percentage. It takes the post text and context (for replies, the parent post) as state, and returns calibrated probabilities. The extension uses these to show tags, collapse hidden posts, and apply user settings.
