Sequence Theory · Sovereignty solutions

You cannot control what you cannot see.

More tools. More dependencies. More of your life and work, scattered and locked behind platforms and sources that are not under your fingers.

The tradeoff

We wanted serious tools without the tradeoff. So we built Donezo.

Your private operation space for life and business.

  • LoginNo login. No accounts.
  • TrainingNo AI training on your data.
  • FragmentationNo data fragmentation. No complexity.
  • DowntimeWorks offline.
  • Their serversKeeps your work where it belongs: on your machine.
The architecture

Work from three fronts. Give up nothing.

Donezo is your private intelligence layer. It works across your local devices, your browser, and your cloud. Connect your drive and your data syncs, so the same work is there wherever you pick it up.

One number. Three apps. Typed once.

Entered once, in a sheet.

Read into a document. Not copied, not retyped.

And onto a page you can publish. Change it in the sheet and all three are already right.

Your devices Desktop and phone.
Your browser Open a tab and work.
Your cloud Google Drive for now, more coming.
Safe by architecture. Not by promise. Your work never reaches us, so there is nothing here to leak, sell, or train on. How it is built, and how to check it.
Private. Local software means the app runs in your browser and the file stays on your disk. Close the tab and the work is still there, in ordinary files, openable by anything.
Four apps. More coming. And you can build your own on top.

Donezo Connected

One payment. Everything connected.

Local is complete on its own. Connected is what happens when your folder, your apps, your cloud and your own AI start working as one.

01 Connected to your folder Your device becomes the source of truth. Durable, portable, yours.
02 Connected to each other Reference what is in one app from inside another, so a number tracked in Grids can be pulled straight into a document in Docs.
03 Connected to your cloud Connect your own drive and your work syncs across every front you use. Google Drive for now, more coming.
04 Connected to your AI Guardians ship inside every app, running on your own key. Prompts go straight to Anthropic or OpenAI. We are not in the path.

NextSpace, for teams.

Bought once. Yours for good.

The costs

Pay once. Replace your tools.

A solo founder can pay €150 to €300 a month across a stack that does not talk to itself. These are the parts Donezo takes over.

Also replaced, not counted aboveAgents · Password manager · Cookie banner · Company brain

The list goes on. We keep building tools, and you can build your own.

4+companies hold your work. Each has a policy, a breach history and a future owner.

Money is the part you can see. The rest is your attention, and it does not renew.

Security

Nobody breaks into one folder. They break into a company holding a million.

Your data is not in that pile. It is in your Donezo folder, on your device, in formats you can read.

  • 4companies. Any one of them gets breached, you get breached.
  • 4accounts and passwords you did not want to create.
  • 4+places your data can leak from, and none of them are yours.
A breach at a vendor exposes everyone at once. There is no everyone here.
01
Your deviceThe folder is on the machine in front of you, in open formats. Not a copy of something held elsewhere. The thing itself.
02
Your cloud, if you want oneConnect the provider you already trust and it holds the backup copy. You inherit their security, the good parts and the bad ones, by your choice rather than ours.
03
Your hard driveCopy the folder to a drive and that is a second backup. No export tool, no request form, no waiting. It is a folder.
04
Your own keyAI runs on a key you paste in. Prompts go straight to Anthropic or OpenAI. There is no Donezo server in the path to log them.

We cannot leak what we never hold.

No account, so there is no password to steal. No session to hijack. No database with your name in it. You can check that yourself right now: open DevTools, watch the network tab, and count the requests.

Before you buy

The questions we get asked most.

Who can use Donezo?

Anyone whose work lives in documents, sheets, files and pages. Founders, freelancers, writers, journalists, researchers, students, developers, and small teams who would rather keep that work on their own device.

Nothing is gated behind a trial. The apps are free to use with no account, so you can test everything you would be paying for before you pay for any of it.

You do not need to be technical. If you can use a spreadsheet and a document, you can use Donezo. If you are technical, the files are plain HTML and your folder is a folder, so git and your own scripts work on it without a plugin.

Can my whole team use it?

Individually, yes. Today you can share what you build through your own Google Drive, so a team can work off the same files without anything passing through us.

Space is what makes it properly shared. When it arrives, your whole team works inside the apps together.

Do you offer refunds?

No, and the reason matters. Every app is free to use and test for as long as you like before you pay anything, so nothing is bought unseen.

What you pay for once is connecting your data and the architecture underneath it, not the apps. That membership covers every new app we ship in this tier and every product update, which is a good deal larger than buying an app.

What are the limitations of Donezo Connected?

It works with the cloud provider you already trust. Google Drive today, with more being added.

There is no real-time sync between people and no built-in sharing yet, so sharing goes through your provider. We are building our own private answer to both, so your data stays in your hands rather than ours.

How was AI used in building Donezo and Sequence Theory?

Everything started with an experiment. We connected the dots and found Donezo.

Donezo was built through an intense testing and feedback loop. Every feature and every function was built, tested and revised until it found the right shape, the one that fits how we think about content and software.

Nothing here was published that a human did not draft or check, question, correct, revise and iterate. We use AI to get things done, in collaboration. We never trust an AI output without validating it ourselves, and neither should you.

With the AI Act now in force, text generated by Claude carries a watermark, including when you use your own API key inside your Donezo OS. And no watermark proves nothing either way.

So what we optimise for is credibility. You only arrive there when your code, your content and your assets have been questioned and tested until they resonate with how you think, not how your AI thinks.
