Filter X posts
by your own criteria.
Find posts worth reading on X with TypeSafe Jev. A free Chrome extension and an open library of rules we can improve together.
MIT licensed · Developer mode install · Your own TypeSafe API key required; API charges may apply
See which posts each rule selects.
Switch goals to compare how different rules match the same posts.
Goal
Reader profile
Interactive illustration: fictional posts and preset scores. No API is called, and these are not Jev results. The extension judges real loaded posts using your own criteria.
Bring your criteria to X.
Download and load
Unzip the extension. At chrome://extensions, enable Developer mode and choose Load unpacked. Select the folder that contains manifest.json.
Define what matters
Open settings, paste the goal and profile into their fields, add your own TypeSafe key, enable automatic judgment, and save. The extension UI is currently Chinese; the English guide translates the controls.
Browse as usual
The extension marks loaded posts with icons and percentages. Optionally compare eligible posts to get up to three top matches.
What makes a post worth reading?
A rule should be reusable and open to challenge. Contribute a reading goal, a criterion, or a counterexample that exposes where a rule fails.
Data flow and costs
This sample does not access your X account or collect an API key. The installed extension sends loaded post text, author handles, engagement counts, and your goal/profile to TypeSafe. Your key is stored in local extension storage; provider API charges may apply. It does not automatically search, scroll, or like posts. A match score is not a measure of truth or accuracy.
