TagSpaces as Local-First Alternative to Evernote and Cloud-Dependent Note Apps

TagSpaces stores your notes as standard files (Markdown, HTML, or TXT) directly on your device—no cloud, no vendor lock-in. Unlike Evernote, OneNote, or Bear, you keep full control of your data with no accounts or subscriptions required.

Sync your notes across devices using services like Dropbox, Google Drive, or Nextcloud—or work fully offline. You can even manage notes stored on S3-compatible cloud storage like AWS, Minio, or Wasabi.

Your notes stay private, portable, and accessible—on your terms.
