CryptPad – realtime collaborative editor

CryptPad is a realtime collaborative editor. CryptPad is an open technology that you can run on your own machines. It doesn’t rely on a central point of authority.

Make quick collaborative documents for taking notes and writing down ideas together.

CryptPad is private, not anonymous. Privacy protects your data, anonymity protects you. CryptPad will make everything you do undecipherable to the outside world before anything is sent to the service to be distributed among all the participants.

Features include:

  • 100% client side encryption. Encryption carried out in your web browser protects the data from the server, the cloud and the NSA. It relies on the ChainPad realtime engine. Chainpad allows users to collaborate without the mediation of a central authority.
