Data watch: User metrics in the note-taking industry frequently conflate registered accounts with active daily users. While platforms like Notion report over 100 million registered workspaces, active weekly editing engagement typically represents 20% to 30% of total registered signups. In addition, default pre-installed operating system applications (such as Apple Notes and Google Keep) maintain large passive user bases that interact primarily for transient checklists rather than structured personal knowledge management.
