Google docs is owned by google and it is centralized. And when it comes to privacy and the crypt you can check out the various services out there. What if any blockchain can offer you such service where your documents go on blockchain and your updates get deployed on the chain? Fireverse does exactly that for the document on the chains.
They have this ddocs product which has been created for deploying the google doc on the chains out there.

You can use the URL : ddocs.new and you have option to login using the wallets, socials etc to start working on the document. Here you have to consider the document where you can type and add the content and then if you choose to own your own server and the portal you can do that using the fireverse as well. There are free and paid plans to execute this.

This is one of the new update for the blockchain use case where you can see the content and the documents updates are being deployed securely and privately on the chain. This would make it easier for the editing, writing and going back on the document making git contribution and also getting it on the blockchain for the legacy updates.
