Searching through your Twitter bookmarks is a common request and currently not possible on Twitter directly. There are some browser extensions but these are not available everywhere and are not as powerful.
Birdfeeder makes it possible to search through all your Twitter bookmarks with an extremely performant full-text search. You can instantly find any tweet you ever bookmarked. Do you only know a few words that were mentioned in the tweet, or maybe just the author? The Birdfeeder bookmark search will find what you are looking for.
To learn more about this new feature take a look at the feature page.
This feature is available for every Birdfeeder user. Free users can search through the last 7 days of bookmarks, Birdfeeder Blue users can search through the full history.
Give it a try and let us know what you think, happy searching!
