Write a note that only a password unlocks
Sometimes you need to store or share a sensitive note, a credential, a private message, without trusting a server with it. This tool creates encrypted notes in your browser, protected by a password, so only someone with the password can read the content.
Why client-side encryption is the point
If a note is encrypted in your browser before it is stored or shared, the encrypted form is useless to anyone without the password, including any server that holds it. That is the difference between trusting a service with your secret and trusting only your password. The security rests entirely on the password strength and on keeping it separate from the note, so a weak or shared-alongside password undoes the protection. Used properly, browser-side encryption lets you handle a secret without exposing it to any third party.
Encrypted before it leaves
The tool runs entirely in your browser, so nothing you paste is uploaded, which is exactly what you want when the input is your own security-sensitive data.

Frequently Asked Questions
How is the note protected?
It is encrypted in your browser with your password, so the stored or shared form is unreadable to anyone without that password, including any server.
Why encrypt in the browser?
Because then the secret is protected before it ever leaves your machine, so you trust only your password rather than trusting a service with the plaintext.
What makes the protection strong or weak?
The password. A strong password kept separate from the note gives real protection; a weak one, or sharing it alongside the note, undoes it.
Can the service read my note?
No, if it never sees the password. The encryption happens in your browser, so only the encrypted form could ever leave it.
Is my note uploaded?
The encryption runs in your browser; the plaintext is never exposed. Handle the password with care, since it is the whole protection.
