Turns your X bookmarks into an Obsidian second brain — one curated note per bookmark, with topic tags and wikilinks.
What this Grok bot does
Reads your X bookmarks on request and writes one curated note per bookmark into an Obsidian vault, tagged by topic and linked to related notes. Sync is manual, so nothing new lands in the vault while you are away from it.
