Hey all thanks for using and asking about Fileverse dDocs and dSheets!
I only just noticed this conversation, let me share some more information and correct some false claims shared in the last comment, which you can all easily verify independently as well.
Fileverse is an end-to-end encrypted workspace and collaboration protocol. It is open source and built to be a sovereign technology that stands in contrast with the Cloud-based alternatives (e.g., Google Docs/Sheets and Microsoft Word/Excel) that over 3 billion people rely on despite their lack of strong privacy and user control.
Fileverse currently includes the dDocs and dSheets apps which are both almost at feature parity with Google Docs and Google Sheets in terms of speed and features (e.g., suggested edits, granular permissions, tabs, version history, collaboration). They also come with unique features and guarantees that are worth mentioning here since y’all are fellow privacy folks:
- On top of e2e encryption by design, we also have additional privacy layers for multiplayer collaboration. When you invite collaborators to your documents or spreadsheets, their email addresses are kept private from Fileverse. We use Verifiable Oblivious Pseudorandom Functions (VOPRFs) + Zero-Knowledge Proofs to enable this and have applied the same logic to account social recovery. Our open source work has also been independently audited. GitHub - fileverse/voprf-server · GitHub
- Your account / files can be recovered via social recovery instead of some relying on Fileverse customer service and arbitrary verification rules. You can set two people (their email addresses) as your “guardians” so that if you ever lose access to your account or your email gets compromised, these two people can cryptographically recover your files and ability to decrypt them without having to ask the Fileverse team anything. Even your guardians’ email addresses are kept secret from Fileverse using the same VOPRF+ZKPs logic as above.
- But much more importantly, if Fileverse or the team goes down, peers that are using our apps will still be able to “force exit” their data and retrieve all the content that is theirs. You can test it yourself here: walkaway dot fileverse dot io. You can also self-host this page or access it via its .onion address for more privacy.
- You can also host your own collaboration server if you want to avoid using Fileverse’s ‘dumb’ servers used for edit collaboration with peers.
Now, to quickly correct the guesses of the previous comment. No, that is not the main author of Fileverse, the person linked was a developer that joined our team for a year. As you can see for yourself on GitHub, Fileverse’s codebase was active prior and post his contributions. We are very intentional about how robust we want Fileverse to be before coming out of beta. This Wired article about us was published last month, hope it can put some colour to what I am sharing here.

Yes, we ship fast. I’ll give you that!
We are a small but feisty ship and are obsessed with the idea that a Internet users globally deserve better than having their most valuable data and accounts in the hands of a couple companies and Cloud services that refuse to give them end-to-end encryption and full control over their digital life. In fact, the parabolic propagation of genAI throughout online services has made us even more convinced that our thesis is correct. We need mass privacy and verifiable technology now more than ever.
As such, we want to make privacy and sovereignty HYPER ACCESSIBLE. We’re not re-inventing the wheel in terms of UX, we want to make the switch from eg Google Docs to Fileverse dDocs as simple and intuitive as possible while giving people better guarantees for their digital lives.
I will stop here so as to avoid making the answer too long (already is haha) but please feel free to ask any questions you might have or share any feedback for the apps! Fileverse got to where it is today thanks to relentless community support so I’m always happy to hear more
