Vertraut Studio · Private AI · No cloud

DE

Your own private AI studio.

Four apps in one private studio: ask your files, draft in your voice, run small agents, and keep a knowledge base. All on your own machine. Nothing goes to the cloud.

Your clients trust you with work the world has not seen yet.

Unreleased products. Campaigns under NDA. Numbers. Names. The moment that goes into a cloud tool from the US, it is out of your hands.

Studios keep getting told they cannot put client work into ChatGPT, and there has been no clean answer. Vertraut is that answer.

What Vertraut is

A private assistant that reads your own documents and answers questions about them, like a colleague who has read everything. It runs on your own machine. It calls nothing to the outside. You own it.

Not software to configure. You download it, it sets itself up, and it works.

How it works

  1. 1

    Download and unzip it.

    One double click sets up a local environment and downloads the models, once.

  2. 2

    Drop your files into the documents folder.

    PDF, Word, text, Markdown. They stay in your own folder, on your own disk.

  3. 3

    Ask in plain language.

    Vertraut answers from your files, names its sources, and never invents what it cannot find.

How you can trust it

It binds only to your own machine and is not reachable from outside. The only network calls it makes are to the local model engine on the same computer. Turn off your wifi and it still works. Your data stays in the house, and the cost never climbs with every person who uses it.

This is the actual app you run on your own Mac.

Common questions

Does anything leave my machine?+

No. Vertraut runs on your own computer and makes no calls to the outside. You can prove it: turn off your wifi and it still answers.

What can it actually answer?+

Anything that lives in your documents. What a brief asked for, which clause was in a contract, what a past pitch proposed, what you filed for a client last year.

What do I need to run it?+

A Mac, and the free Ollama app (the kit links you to it). A few gigabytes of disk for the local models, downloaded once. No account, no subscription.

Are my documents used to train anything?+

No. Never. Your files stay in your own folder and feed into no model training.

What does it cost?+

Vertraut Studio is a one time €99. You download it and own it, with no per month fee. If you would rather we set it up for you, Done for You is €399.

More questions? The assistant in the corner answers instantly, on your device.

A private AI that stays yours.

Buy it once, run it on your own machine, keep your work in the house.
