BookmarkBrain

About

Your saved posts are a graveyard. 🪦
No search. No recall. No value.

BookmarkBrain turns your X/Twitter bookmarks and Reddit saved posts into a second brain you can actually talk to.

Ask natural language questions and get cited answers grounded in what you actually saved, like having a personal research assistant over your own content.
