Private by design

Snipfern only runs on the sites you turn it on for, one at a time or all at once. It looks at the few characters right before your cursor to spot a shortcut, on your device, and never sends what you type anywhere. Your snippets live in your browser's extension storage. The extension has no account, no server, no ads and no analytics. Its only connection is to Gumroad's license check, when you choose to unlock Pro. Read the privacy policy.

Questions

How is this different from Text Blaze or Magical? Snipfern keeps everything on your device with no account, and Pro is a one-time $9 instead of a monthly plan. It doesn't have team sharing or cloud sync.

Can I move my snippets from another expander? Yes: import a CSV with shortcut,text columns, or a JSON export that uses fields like abbreviation and phrase.

Does it sync between computers? No. Use Export and Import to copy your snippets to another computer.
