Each conversation has its own isolated computer, running Linux. There is nothing to turn on: the AI starts it when the task calls for a calculation, a file analysis or a document to produce.
What it can doLink to the What it can do section
| Task | Example request |
|---|---|
| Analyze data | “Here is our 2026 sales export: calculate revenue by month and plot the curve.” |
| Produce a document | “Write me a two-page Word report from these notes, with a table of contents.” |
| Build a spreadsheet | “Build a 12-month budget forecast in Excel, with the formulas.” |
| Work on PDFs | “Merge these three PDFs and number the pages.” |
| Run an exact calculation | “Calculate the monthly payments on a €180,000 loan over 20 years at 3.4%.” |
| Read a building model | “Take off the wall quantities from this IFC model, by level.” |
The AI runs commands, Python and JavaScript there, and has tools for documents (Word, Excel, PowerPoint, PDF) and charts. Skills that contain scripts also run in the computer.
How it worksLink to the How it works section
- You attach a file, or ask for a result that needs a calculation or a file.
- The AI starts the conversation’s computer and copies your attachments there, photos included (up to 20 files per message, 50 MB each). Images generated in the conversation are also available there, so they can be inserted into a document.
- It runs its commands. The steps are shown above the answer.
- The files it produces are delivered below the answer (10 at most at a time): you can open and download them. They are also stored in your Library.
The work stays in the computer from one message to the next within the same conversation: you can ask for a correction without starting over. Executable programs (for example .exe or .msi) are never delivered.
Attached photosLink to the Attached photos section
A photo attached to your message is copied into the computer like an attached file: the AI finds it with your other attachments and can use it, for example to place it in a document. The photo is copied with the message it belongs to: if the AI cannot find a photo you sent earlier, attach it again. Like any file in the computer, it stays there until the end of the retention period (see Lifetime).
IsolationLink to the Isolation section
- No internet access: the computer downloads nothing and cannot install new programs. The AI works with the tools already there and with your files. For information from the web, it uses web search, outside the computer.
- One computer per conversation: it is not shared with your other conversations or with anyone else.
- On Moon AI’s servers: in the same place your files are stored.
- Moon Blur: what the computer sends back to the model (command output, content it reads) goes through Moon Blur. The files delivered to you contain the real values (Moon Blur).
LifetimeLink to the Lifetime section
| When | What happens |
|---|---|
| While you are working | The computer stays on and keeps your working files. |
| After about ten minutes without a command | It goes to sleep. It wakes up on its own at the next message, with its files. |
| After the retention period | It is deleted, along with its working files. Files already delivered stay in the conversation and in the Library. |
How long it is kept after the last activity depends on your plan. If the computer has been deleted, the conversation gets a new, empty one at the next task.
Plan and usage limitLink to the Plan and usage limit section
The isolated computer is available on every plan. Its memory, the number of computers active at the same time, the retention period and the maximum length of a command depend on the plan: see pricing.
Using the computer counts toward your usage limit, and starting it is the most expensive step. So the AI handles simple calculations itself and saves the computer for real calculations, data files and documents to deliver.
Where it is not availableLink to the Where it is not available section
- In a “Confidential chat”.
- In routines, agent tasks and conversations from connected messaging apps.
- With a model that cannot use tools.
- With a community agent.
- Through the developer API and in Moon CLI.
Without the computer, the AI still answers; if it cannot produce a file any other way, it gives you the content as text.
IFC modelsLink to the IFC models section
Attach an .ifc or .ifczip model exported from Revit, Archicad, Allplan or another program, up to 50 MB per file. A heavier model can be compressed to .ifczip. The AI reads its levels, its elements by type and by level, quantities (lengths, areas, volumes) and properties, delivers an Excel or CSV table and checks that the model is consistent.
If the computer is not availableLink to the If the computer is not available section
If the AI tells you that the conversation’s computer is not available, open a new conversation: it will get a fresh one. If the AI says the computer was reset, the previous working files no longer exist, but files already delivered remain available.
