I'm Nova Stellaris, an AI agent connected to your computer, your online tools and your business. You talk to me: I give you a briefing every morning, prepare your quotes, keep your calendar and tell you what matters.
A conversation in the middle. Your tools right beside it.
Like a secretary who knows your business inside out. Follow one day with me, around a single client: Paul Renard, from Café Quartz, who writes at 8am because his shop window won't close any more.

What makes me different
Three things no chatbot does.
You've already tried ten AIs. They answer, then they forget. And the work is still waiting.
01
I remember you.
Your clients, your prices, your decisions: I keep it all, so you never have to repeat yourself. Each person on the team has their own memory.
02
I act. You decide how far.
I prepare the email, the quote, the task. At first, I ask for your approval before every action that matters. Once you trust me, you let me get on with it. You set the dial.
03
I live with you.
A server in your name, a database just for your company. Your memory and your files never sit next to anyone else's.
Every day
What I do for you, every day.
You've seen the app. Here's what it changes in your day: fewer tasks left hanging, more time for your clients.

I watch your inbox. Newsletters and automatic notifications go straight past.

At your place, not ours
Your data stays within your walls.
Most AI assistants keep everything on their own servers, with all their clients' data. I move in with you instead.
One server and one database per company. Nothing is shared with another client.
One account per person, by invitation. A code valid for 72 hours, then a password only that person knows.
A backup every night. Server unreachable? The conversation carries on.
Updates are offered to you. Nothing installs without your click.

Pricing
A simple price, per person.
Nova Stellaris is in beta. Installation and setup are our job: you pay for use, nothing hidden.
Nova StellarisBeta price
€49excl. VAT per user per month
+ €350 excl. VAT for installation, one time only
The beta price. It may change with the final version.
Isn't it just ChatGPT or Claude with an interface?
No. To reason, I rely on a large model of your choice: Claude from Anthropic, GPT from OpenAI, Gemini from Google or Grok from xAI. But a model on its own forgets everything and can't touch anything. Around it, Nova Mind built my memory, your projects, your calendar, your files, your quotes and my alerts. And you decide what I do on my own.
Where is my data?
On your server: your memory, your files, your tasks, your accounts. One database per company, backed up every night. To reason, I send the conversation to the chosen model, using each user's own account. We go through it all in the demo.
What if you get a quote wrong?
By default, I prepare and you approve: before every action that matters, I tell you what I'm about to do, in one sentence. For quotes, you can keep that setting for as long as you like.
Do I need to be technical to use you?
Not at all. You talk to me normally, in writing or by voice. Installing the server is our job. And the first launch guides you step by step.
Which tools do you work with?
Your Google Calendar, your projects and your team files are in the app. For the rest, tell us what you use during the demo: we'll see what can be connected.
How much does it cost?
During the beta: €49 excl. VAT per user per month, plus €350 excl. VAT for installation, one time only. Each user also has their own AI account: Claude, ChatGPT, Gemini or Grok. Team training is optional and can be funded by your OPCO (the French training fund).
