Winnow

Winnow is a Google Chrome extension designed for X (formerly Twitter) users to filter and identify posts worth replying to. The tool runs locally in the browser and does not require AI, APIs, or user accounts. It scores posts from 0 to 100 based on freshness, headroom (the gap between views and replies), and user-defined keywords. High-scoring posts are highlighted with a colored border, while low-scoring posts are dimmed to keep the timeline focused.
