Majik Message is a browser extension for encrypting and decrypting text directly in your browser. It is not a chat platform — it does not host conversations or store messages on a server. Instead, it allows you to securely encrypt text, share it with contacts, and decrypt it on any webpage, giving you full control over your data.

- Add multiple contacts who can decrypt your messages.
- Share your account via invite key for collaborative access.
- Save, export, and import your account as a JSON file or backup key.
-
Page-Wide Decryption
- Decrypt all valid encrypted strings on a page in a single action.
-

- Enable the scanner in settings to automatically detect and decrypt valid encrypted text on any webpage in real-time.
-
Privacy-First Design
- All encryption and decryption occur locally. Messages are never stored on a server unless explicitly saved by the user.
- Highlight text → right-click → Encrypt.
- Replace the text with an encrypted string or copy it.
- Highlight encrypted string → right-click → Decrypt
- Decrypt the entire page → right-click → Decrypt Page
- Or enable the scanner to auto-detect and decrypt strings on a page
- Create an account from a seed phrase.
- Add contacts or share your account via an invite key.

Injects a content script for detecting and modifying page text.
Uses standard cryptographic algorithms (AES, RSA or other implemented schemes) for end-to-end encryption.
Local storage using browser storage APIs (optional JSON backup).
Observes DOM mutations to detect and auto-decrypt valid encrypted strings.
Majik Message uses seed-based accounts. No email or registration is required.
