Swiss, privacy-first AI chat
The leading AI models. Without a record of who asked.
ZeroLog.ai is a privacy layer between you and the providers. Your conversations are stored on your own device — there is no permanent server-side copy of what you typed or what came back.
The privacy benefit is not that the provider cannot read the request. It is that the request is separated from your direct consumer identity.
The hesitation before you paste it in.
There is a familiar pause before pasting a client contract, a set of financial figures, a medical detail or an internal business document into a consumer AI service. ZeroLog.ai is for that pause: the same leading models, without connecting the question to your personal accounts with those providers.
Stored on your own device
Your conversations are saved locally, in your browser. The server never receives a copy to keep.
How much, never what
Your account is linked to the number of tokens you spent. It is never linked to the words you spent them on.
A request from ZeroLog.ai
The provider sees a request from ZeroLog.ai under one shared service identity — not a person at an address.
A privacy layer between you and the provider.
The provider sees the request — it needs the content to answer it. What it does not receive is the request from your personal consumer account with that provider: it receives it from ZeroLog.ai, under one shared service identity. That separation is the product, and it is enforced in the code rather than promised in a policy.
What we hold
- Your email address and the password you set.
- An active sign-in session.
- A usage counter: tokens spent, requests made.
- A 90-day log of sign-ins, sign-outs and password resets.
What we never hold
- What you asked, in any form.
- What the model answered.
- Any record linking your account to either — not even briefly.
- Your files. A PDF you attach is read on your device and stays there.
How ZeroLog.ai works
Sign in with an email and a password.
That is the whole account. No name, no phone number, no address book.
Type your message.
The conversation is written to your own browser storage as you go.
Your turn is sent through our Swiss servers.
The conversation travels with it, because the server keeps nothing of it between turns.
We pass it to the provider under one shared service identity.
Details that identify you are stripped before the request leaves, and there is no other route out.
The answer streams back to you.
When the stream closes, the request is gone from the server. Your usage counter goes up by what it cost.
Built for anything you would keep separate.
Some conversations carry information you would not want linked back to your personal accounts with an AI provider — professional or personal.
Professionals
- Lawyers, accountants, consultants and wealth managers.
- Anyone else who routinely handles confidential client or company information.
Individuals
- Personal conversations you would rather keep to yourself.
- Medical, financial and other private questions.
All the leading models. One private interface.
Model choice matters: one private interface, several leading models, and the ability to pick whichever suits the task in front of you — then switch the moment it stops.

What comes with it
- Attach a PDF: its text is read on your device, and no bytes are uploaded.
- Export your whole history to a file, in one click, whenever you want it.
- Point ZeroLog.ai at a folder you already control — iCloud Drive, Dropbox — and your history follows you between your own devices. The folder is yours.
Powered by renewable energy.
During the testing phase, ZeroLog.ai runs on AWS infrastructure in Zurich. From launch, all ZeroLog.ai-operated infrastructure—including the website, accounts, usage systems and our own locally hosted AI models—will run on servers located in Geneva and powered by renewable energy.
The exception is external AI models accessed through our platform. Those requests are processed through the relevant provider's API and may run on the provider's own infrastructure outside Geneva. We will always distinguish clearly between what runs on our Swiss servers and what is processed by an external model provider.
Different from a mainstream AI account. Different from a privacy tool, too.
ZeroLog.ai sits in its own place: not a consumer AI account, and not one of the other privacy-focused alternatives either. The differences are specific enough to set out side by side.
Swiss jurisdiction. Swiss legal process.
Your account, your session and your usage counter live in our own Swiss database. Production is planned to run in AWS's Zurich region, so a request leaves from Switzerland and is answered back into it.
What it costs, in one place.
Pricing is not settled yet, so we are not putting a number on this page before it is right. The pricing page carries what is decided so far.
Who operates ZeroLog.ai.
ZeroLog.ai is intended to be operated by a Swiss company, run as a business administration entity kept separate from the underlying intellectual property, which is planned to sit in its own, separate company.
Three questions people ask first.
- Does the provider see my messages?
- Yes — it needs the content to answer. What it does not receive is your identity: the request arrives from ZeroLog.ai, not from you at your address.
- Is ZeroLog.ai completely anonymous?
- No, and we would rather say so plainly. You hold an account with an email address; what you get is separation from the provider, not invisibility.
- What happens if our data is requested through legal process?
- There is very little to hand over: an email address, sign-in history and a usage counter. We hold no record of what was asked or answered, so a legal request cannot reach content that was never stored.
Your chats should belong to you, not to the platform.
Clear control over what is retained, and control that stays with you.
