CryptPad is:

- an office suite, where La Suite is at least partly a coherent package bundling existing software which has documents, chat, video calls, etc but wouldn't really play the role of an office suite IIUC - they serve different purposes mostly

- E2EE, which comes with its unique set of benefits and drawbacks

(and yes, sadly at XWiki SAS we host our code on GitHub too, I wish it wasn't like this)
