Our two products

01The assistant

An AI assistant on your own machine

Clerc takes care of day-to-day tasks that take up your time. You can give it a piece of work that it repeats at fixed times, and connect it to about a hundred online applications, for example for task management, team chat or document sharing.

It runs on a machine with GPUs. Coming soon: you will also be able to use it from a phone connected to your office network.

Every Friday at 5 pm, go through the week’s exchanges with each client, update their file, add the agreed meetings to the calendar and prepare the follow-ups.

Scheduled. Every Friday, I will:

02Made to measure

Connected to your office’s own software

This offer includes the assistant and everything it does. After an audit, we also connect it to your office’s own software, such as practice or accounting software, and automate the tasks your team does by hand today.

Why in your office

To work with your data, an online AI service has to receive it. With Claustel, your documents and your questions are never sent to such a service: the machine that answers your questions is in your office.

Our only way in from outside is remote access that you open. It is closed by default, reserved for named people, and every session is entered in a log you can read. If you close it for good, our remote maintenance stops, but the system keeps working.

Remote access is closed.

How we start

We meet your team, then send you a written plan with the test and the price.
Installation
We find the right machine and order it for you; we install everything and train your team.

Open models

The language model is an open model: its author publishes its files. We choose it with you and name it in the written plan. You can use your copy with no time limit.

A new model replaces yours only after doing better on your own test, and the old one stays available.
