xmark: chat your X bookmarks

xmark turns your X (Twitter) bookmarks into something you actually use.

you save hundreds of posts you never scroll back to. xmark syncs them, understands them, and lets you ask questions across all of them in plain language - with every answer cited back to the original tweet.

chat with your bookmarks
ask "what did i save about ai agents?" or "that thread on pricing" and get a real answer, with citations to the exact posts.

semantic search
search by meaning, not just keywords. find the bookmark you half-remember.

xmark wrapped
your bookmarking, summarized: most-saved creators, top topics, total saved - shareable on x.

free to start: 20 chats a month, one sync a day. upgrade to pro for unlimited chat and sync.
