Local SI (AI) Agent

SimpleAppli-Agent

Your conversations and files never leave this PC.
An SI (AI) that runs inside your PC helps with everything from organizing files and creating Office documents to programming.
It asks for confirmation before risky operations and runs commands in an isolated environment.

What's different

How it differs from cloud SI (AI) services

Cloud services are convenient, but what you enter is passed to servers outside your organization.
What SimpleAppli-Agent changes is where it runs and how you decide how much to leave to it.

01 / LOCAL

Your conversations and files
never leave this PC

The large language model runs on your PC, using an execution engine built into the app. As long as you use a model on "This PC", the content of your conversations and the files you work with are never sent to servers outside your organization (except search queries when you enable web search).

More about how it runs inside your PC →
02 / SAFETY

Risky operations are
confirmed before they run

Before rewriting, moving or deleting files, or running a command, the app shows what will change and asks every time whether it may proceed. Commands and tests are confined in a Docker container and run with the network disconnected.

How it keeps delegation safe →
03 / UNDO

Delegated work can be
rolled back request by request

If you don't like the result after leaving a task to it, you can restore the workspace files and the conversation to the point before that request, and then redo the request.

Features

Key features

01 / LOCAL MODEL

A large language model
that runs inside your PC

  • A model is downloaded only once, the first time you use it, and from then on runs inside your PC
  • Choose from model cards (a model paired with settings for how to use it) such as Gemma 4, Ornith 1.5 and Qwen3.8
  • When you first start, choose what you will use it for, and it recommends models that run with this PC's memory. You can also check in the model list whether a model can run
  • Works with NVIDIA, AMD and Intel GPUs, and also without a GPU (generation is slower)
02 / AGENT

What you can leave to it
(Standard plan and above)

  • Read, create, rewrite, move and delete files in the folder you set as the workspace
  • Create Word, Excel and PowerPoint files, and rewrite them while keeping their formatting
  • Research by searching the web and reading search results or pages at URLs you specify
  • Analyze code, and run commands and tests in an isolated environment
  • Use skills (written procedures) and expert configurations for work by set procedures or shared among models
03 / SAFETY

Built so you can
delegate with peace of mind

  • Rewriting or deleting files and running commands are confirmed after showing what will happen (auto-approval is also available)
  • To protect your PC and data, commands and tests run inside a Docker container with the network disconnected
  • A read-only mode for when you want analysis only, without any files being rewritten
  • Roll back files and the conversation to the point before a request

* The safety mechanisms are meant to reduce harm; they do not guarantee that all harm is prevented. Please back up important files.

How to get itSerial code (by contract)

For Business

For business customers

For the Business plan, we issue serial codes under a contract. For environments that cannot use the Microsoft Store, we also provide an installation package (Windows) that does not go through the Microsoft Store. Mac and Linux versions are also available with the Business plan.

Requirements

System requirements

OS Windows 11. Mac and Linux for the Business plan only (please contact us).
GPU 8 GB or more of VRAM recommended (NVIDIA, AMD or Intel). The app runs without a GPU, but generation is much slower.
Memory 8 GB or more, 16 GB or more recommended (for the default model; larger models need more).
Storage Free space according to the size of the model (about 4.3 GB for the default model).
Network Required each time the app starts (to sign in and check your plan; in the Business plan version that does not go through the Microsoft Store, also to check for a new version). Also required to download models and expert data.
Docker Required only if you use isolated execution of commands and tests (Docker Desktop, etc.).
FAQ

Frequently asked questions

Will my conversations be used to train models?

When you use a model on "This PC", the content of your conversations is sent neither to us nor to any other company, and is never used for training. When you use a model on a server you have specified through a remote connection, it is sent to that server. If you enable web search, search queries created by the agent are sent to an external search service (Tavily, in the United States) and may be used to improve its services and to train AI (see our Privacy Policy for details).

Can I use it on a PC that is not connected to the internet?

No. An internet connection is required each time the app starts, to sign in and check your plan (and, in the Business plan version that does not go through the Microsoft Store, to check for a new version). A connection is also required to download models and expert data. The connection is needed only for these purposes; your conversations and files are not sent (except search queries when you enable web search).

Does it run on a PC without a GPU?

Yes, but generation is much slower. It also runs on GPUs built into the CPU, and you can check in the model list whether a model can run.

Do I need Docker?

Only when running commands or tests in isolation. All other features work without Docker.

What can I do on the Free plan?

You can chat with all of the basic model cards. Tools such as file operations are available on the Standard plan and above.

Can I use it on a Mac or Linux?

Mac and Linux versions are available with the Business plan. Please contact us.

How do I check for updates?

You can check at any time with "Check for updates" in the account menu at the bottom left of the screen. In the Microsoft Store version, this opens "Downloads and updates" in the Microsoft Store; in the Business plan version that does not go through the Microsoft Store, you can download a new version on the spot if one is available (a mark appears in the account menu when a new version is available). In addition, when an update becomes mandatory, a notice screen appears when the app starts.

Are bug reports sent?

When an unexpected error occurs, the location where it occurred and the type of error are sent to us. The content of your conversations, the contents of your files and the locations of your files are not sent. You can stop this with "Send bug reports" on the settings screen.
