An encrypted notepad
Note Newt is a simple encrypted notepad that runs in your browser and installs like an app. Notes are protected with AES-256-GCM, the same encryption trusted for sensitive data everywhere — and the encryption happens on your device, not on a server.
How the encryption works
Each note is encrypted with a key that lives on your device. When you add a passphrase, that key is wrapped using a value derived from your passphrase (PBKDF2, 600,000 iterations) — so the key can only be unlocked by you. This is called zero-knowledge encryption: the server stores only ciphertext and literally cannot decrypt it.
Because your passphrase is the only way in, we also give you a one-time recovery code when you set it up. Keep it somewhere safe — it's the backup key to your notepad.
