In the “On this Mac” workspace, AI runs on your computer, where your conversations and files are stored.

01 — Start with your needs

Make your knowledge easier to use

At work, in an association or for your own projects: start with a practical need.

Find information

A procedure buried in your documents? Import them and ask your question instead of rereading every page.

“What is our returns procedure?”

Understand a document

A document needs a second look? Ask about its content to identify the points worth checking.

“What are the key points in this document?”

Prepare a piece of writing

A blank page to get past? Ask for a first draft, then adapt it with your own experience.

“Help me write a welcome message.”

Illustrative example questions, not customer testimonials.

AI can make mistakes. Check important answers against the original documents.

See how Nosia can help a small business, an association or a team find information and pass on knowledge.

02 — The product in practice

A place to ask questions. And move forward.

A conversation to think things through, your documents to add context. The interface stays focused on what you want to do.

  1. Ask your question

    Use your own words to explore an idea or prepare a piece of writing.

  2. Add your documents

    Attach a PDF or import knowledge sources into your account.

  3. Choose your workspace

    The selected account determines which sources are used in the conversation.

03 — How it works

Your knowledge. A model. The right connections.

Choose the building blocks you need. You don’t have to connect everything to get started.

  1. Your documents

    Import useful content. Document search adds context to your questions.

  2. Your models

    A local configuration on Mac, or models configured for your instance.

  3. Your tools

    Connect compatible services, with their permissions, when your use case calls for it.

  4. Your deployment

    On a compatible Mac or on infrastructure administered by your team.

What about the technical details?

RAG (Retrieval Augmented Generation) enriches answers with passages found in your documents. MCP (Model Context Protocol) links AI to tools and external sources. The OpenAI-compatible application programming interface (API) lets you connect existing clients; compatibility depends on the functions and models you use.

06 — Dilolabs & the community

An open product. A team by your side.

Nosia is developed by Dilolabs, in Normandy. Cyril, Aude and Melvin are its three co-managers. The company helps organizations with their digital tools and practical AI use cases.

Let’s talk about your needsMeet Dilolabs

How Nosia began

Nosia grew from a conviction shared by Cyril, Olivier, Aude and Melvin: technology should serve people, not the other way around.

In 2024, Olivier introduced Cyril to a way of grounding AI answers in documents. Cyril came up with the name Nosia. Their aim: make these tools accessible while keeping control of the data.

In June 2026, François, who runs the Kokori Kodo YouTube channel, created an early presentation video. Find it in the resources below on the French homepage.

Our commitment

We defend the right to choose where our data is processed, which models we use, and how our tools evolve. The right to understand a system, adapt it, and be able to switch to another.

FAQ

You might be wondering

FAQ

Is Nosia free?

Nosia is free to install and its code is open under the MIT license: anyone can read it, use it and contribute. This does not mean that every hosted service or support offering is free.

Is my Mac compatible?

The requirements in the guide above list the chip, macOS version and memory to plan for. Check your configuration in the Apple menu, then About This Mac. This app is not intended for Intel Macs.

Where is my data stored?

In the On this Mac workspace, AI runs on your computer and your conversations and documents are stored there. If you choose Nosia Cloud, another server or external connections, where data is processed depends on that workspace and its configuration.

Why does the first launch download files?

Setup downloads the resources needed to run AI on your Mac. It needs internet and may take time depending on your connection. Nosia shows progress and lets you cancel.

Can I trust every answer?

No. Like any AI, Nosia can make mistakes or misinterpret a document. Check important information and do not replace professional advice with an automatic answer.

Which models and tools can I use?

The Mac installation includes a local AI configuration. For a team instance, models are configured to suit your hardware and needs. The platform also supports connections through the Model Context Protocol (MCP), an open protocol linking AI to tools. Review the permissions and data sent to each service.

Can Dilolabs help me get started?

Yes. Dilolabs, the company developing Nosia, can help with your use cases, deployment and onboarding. Use the contact link below to describe your needs; no price or commitment is implied.

What happens when I close Nosia?

Closing the window keeps Nosia running. Quitting the app stops its local services and saves your data for the next launch.

Your first step: a practical need.

Try Nosia with your documents, explore the code or talk to Dilolabs about a deployment that fits your needs.
