The problem

3,000+
bookmarks saved, on average

Bookmarks pile up

You save tweets all day long. But X/Twitter buries them in a single unsorted list you will never scroll back through.

97%
never opened again

Gone the moment you save

No reminders, no search, no tags. X/Twitter treats your bookmarks as a write-only database.

12 sec
avg. catch-up with a digest

Life is too short to scroll

You don’t have 30 minutes to re-read old tweets. A daily digest takes less time than making coffee.

A 60-second tour of Bulkmark.

From your first sync to your weekly digest. Watch how thousands of saved tweets become a tidy library you actually revisit.

No sound required. Captions inside.

Sync + Auto Tag

One connection. Every bookmark, tagged.

Link your X account once. New bookmarks sync automatically and get tagged by topic (AI, Design, Dev, Business) before you even open the app.
