About Winnow
Winnow is a productivity Chrome extension designed to help users grow their audience on X (formerly Twitter) by identifying and highlighting the high-value posts worth replying to. Created by software engineer Pablo Fernández, the tool simplifies timeline filtering so you can focus your engagement where it matters most.
As you scroll through your X timeline, Winnow scores every post in real-time using local arithmetic instead of AI. This ensures maximum privacy, as absolutely nothing leaves your browser. The scoring system evaluates posts based on their age, view count, number of replies, and your own custom keywords. Posts that score below your specified threshold are dimmed, while the top-performing posts are highlighted so you can reply quickly and grow your presence efficiently.
Winnow offers a generous free tier that supports unlimited scanning with up to 10 highlighted posts per day. For power users, a Pro tier is available for a flat, one-time fee with no recurring subscriptions.

- Does not feature AI capabilities, which some users looking for automated writing assistance might expect
Frequently Asked Questions
How does Winnow score posts on X?
Winnow scores posts dynamically as you scroll your timeline using a local arithmetic formula. The score is calculated based on the post's age, view count, reply count, and your own custom-defined keywords.
Is my data safe with Winnow?
Yes. Winnow does not use AI and does not send your data to external servers. All calculations are performed locally, meaning nothing ever leaves your browser.
What is the difference between the Free and Pro tiers?
The Free tier allows unlimited timeline scanning but limits you to 10 highlighted posts per day. The Pro tier costs a one-time fee of $29 (no subscription required) and removes the daily highlight limit.
