X has a built-in bookmarks tab, but it's a flat, unsearchable list with no way to export, organize, or get notified about what you saved. bookmarks.md turns that list into something useful.

The Verdict
X's built-in bookmarks are where you save things. bookmarks.md is where you actually use them. The built-in list gives you no digest, no search (without Premium), no AI, and no API. If you have more than a few dozen bookmarks, you've already felt the problem.
