ブクマ保管庫: A Local PDF Archive for X Bookmarks

hokanko.app Observed source

Editorial interest 82/100 Selection signal · not a rating of the site

A Chrome extension that saves X bookmarks as conversation-aware PDFs, then removes successfully archived items from the bookmark list.

Landing page captured for the 2026-09-06 issue.

Field notes

The extension creates one PDF per bookmarked post and can include the conversation origin when a reply is saved, rather than treating each post as an isolated artifact. It caps each run at 50 items, records successes and failed stages in archive_log.csv, and stores the cumulative saved count in chrome.storage.local. Videos are not preserved as video: the output records a thumbnail and play marker. The page says bookmark contents and PDFs remain on the user's device, while contact messages are the only described data sent to an external mail service.
