CryptPad is a private-by-design alternative to popular office tools and cloud services. All the content stored on CryptPad is encrypted before being sent, which means nobody can access your data unless you give them the keys (not even us). CryptPad features real-time collaborative editors for rich-text and markdown documents, markdown presentations, polls, kanban boards and whiteboards and allows the sharing of files and folders.

CryptPad is the Zero Knowledge realtime collaborative editor.
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.

Setup using Ansible
CryptPad is private, not anonymous. Privacy protects your data, anonymity protects you. As such, it is possible for a collaborator on the pad to include some silly/ugly/nasty things in a CryptPad such as an image which reveals your IP address when your browser automatically loads it or a script which plays Rick Astleys's greatest hits. It is possible for anyone who does not have the key to be able to change anything in the pad or add anything, even the server, however the clients will notice this because the content hashes in CryptPad will fail to validate.
Still there are other low-lives in the world so using CryptPad over HTTPS is probably a good idea.
We'd like to make it easy for more people to use encryption in their routine activities. As such, we've tried to make language-specific parts of CryptPad translatable. If you're able to translate CryptPad's interface, and would like to help, please contact us!

CryptPad is actively developed by a team at XWiki SAS, a company that has been building Open-Source software since 2004 with contributors from around the world. Between 2015 and 2019 it was funded by a research grant from the French state through BPI France. It is currently financed by NLnet PET, subscribers of CryptPad.fr and donations to our Open-Collective campaign.
We love Open Source and we love contribution. Learn more about contributing.
