If your vault is messy or you are migrating from Notion, Evernote, or Apple Notes, Claude can batch-process the entire thing. One user cleaned files in a single pass. Claude removed duplicates and repaired broken wikilinks. It also reconnected orphaned notes that had no incoming links.
Exports from other tools arrive with inconsistent formatting and broken links. Leftover metadata is common too. I'd recommend committing everything with git commit before you run any batch operation. Claude greps for patterns across hundreds of files and fixes them systematically. If something goes wrong, you roll back in seconds instead of fixing files by hand.
