Hunter's comment
With CryptPad, you can make quick collaborative documents for taking notes and writing down ideas together.
CryptPad is an open-source tool that makes real-time collaboration done easily. It provides tools similar to popular office software and cloud services. Documents can be shared by simply sharing a link and providing a decryption key.
CryptPad is encrypted before being sent, which means nobody can access your data unless you give them the keys (not even us).
It uses modern zero knowledge cryptography and all of the encryption is done on the client side. Users can easily manage and organize multiple pads, upload files using CryptDrive, etc.
They offer three tiers user plans: anonymous users, registered users, and premium users. Depending on the frequency of use, features needed, and data storage need users can decide which tier to go with.
Please visit their website and GitHub to see the detailed features of CryptPad.
