The Efficient Word Count plugin keeps track of word counts across your entire vault without slowing you down. It builds a cache of every Markdown file's count, listens for changes like edits, renames, or deletions, and updates instantly, so the data is always fresh. That cache is stored on disk, which means even big vaults start up quickly with accurate totals already ready. You can fine-tune which folders get skipped - like Templates or trash - and even tap into the global API to pull counts into DataviewJS or your own scripts.
