Local-first social bookmark archive & search

Pull your X/Twitter bookmarks and likes into a local, searchable, backup-able library

Problem

Heavy users treat likes as bookmarks, ending up with tens of thousands of saved items. The native list only scrolls forever; if you remember a phrase but not the author, it is basically lost. Worse, these saves depend entirely on the platform: account limits, deleted posts, or UI changes can wipe them out. Parallel discussions about free signups not being real customers show users increasingly prefer lightweight, local, account-free tools.

Solution

A browser extension or desktop app that automatically captures your bookmarks and likes from major platforms, storing text, author, URL, media, and timestamps in a local database (SQLite/Dexie). It offers full-text search, tag/time filters, and one-click export to Markdown/JSON/HTML, with optional scheduled incremental sync and deduplication. The core promise: offline, self-owned, platform-independent.

Users

Power savers, researchers, content creators, and operators building swipe files or competitive research libraries

MVP

Support one or two platforms (e.g., X bookmarks + likes) for capture; local SQLite storage with full-text index; search by keyword/author/date; bulk tagging and Markdown export; manual one-click backup sync

Revenue

Free tier limits archive size or platform count; one-time purchase or annual subscription unlocks unlimited archiving, multi-device sync, and export templates; a Pro encrypted cloud backup tier later

Why now

Platforms are less stable and content can vanish any time, raising sensitivity around data ownership. Browser extension and local database stacks are mature enough for a solo dev to ship a usable version in 2–4 weeks with no heavy backend.
