This takes about ten minutes, most of it the agent’s analysis.
1

Create your account

Open light.aius.co/login, choose Register, and enter your email and a password of at least 12 characters. Create account signs you in.
The AIUS sign-in card with the Register tab selected, an email address, a password and the Create account button
You land on the Projects page of your personal organisation, named after your email address, for example Personal (ana.lopez). It is yours from the start: create projects in it, publish to it, and invite colleagues later if you want to. The page opens with how AIUS works: the analysis runs in the terminal on your computer, next to your data, and its results come here. There is nothing to upload.

Install the terminal

On macOS (Apple Silicon) or Linux (x64), run this; on Windows, run it inside WSL:
aius works in the same terminal; when the installer asks you to, run . ~/.aius/env first. Installation covers updating, specific versions and the Python packages the data tools use.

Sign in from the terminal

Go to a folder that holds your data and start AIUS. The first time, it asks you to sign in:
The AIUS terminal sign-in screen: Sign in to AIUS, AIUS models and AIUS Light, with browser and device code options
Press Enter (or choose browser) to sign in, or to create an account, in your default browser. Choose device code (Ctrl+D) to approve from any browser. The terminal then shows an address and a code:
The AIUS terminal sign-in dialog showing Connect this terminal, the address https://light.aius.co/device and the code 7A95-SNJM, waiting for approval
Open the address, check that the code matches and choose Allow access.
The Connect a terminal page in the browser, showing the signed-in account, the same code 7A95-SNJM, what AIUS models and AIUS Light may do, and the Allow access button
One approval connects both the AIUS models and your web platform account. AIUS then links the folder to a project in your personal organisation in AIUS Light, and says so. Your files stay on your computer. Your conversations, including what the agent reads from your files, are kept in AIUS Light so you can continue them on any computer (Folders and projects). The home screen shows the project as AIUS Light: term-deposit-campaign; click it to open the project in your browser. Until it has a report, the project page explains how AIUS works for it: you ask in the terminal, and the report appears there.

Ask a question about your data

Describe the decision you need to make and point the agent at your files. Ask for the evidence you want to see, and say where the result should be published:
A prompt typed into the AIUS terminal asking for a propensity model on data/bank-marketing-campaigns.csv, published to a new project in the AIUS Examples organisation
The agent inspects the data first, writes its code under output/, runs it in your project’s Python environment and checks its own numbers.

Approve, publish and read the report

The agent publishes reports to the project your folder is linked to by itself. Here the result goes to a new project in another organisation, so it asks first, proposing to attach its analysis code, executed notebook and aggregate results and to keep the raw contact rows and row-level predictions local:
The agent asks: May I attach the analysis code, executed notebook and aggregate results to the organisation report? Options: Approve evidence attachments, Report text only, Type your own answer
It then reviews the report, publishes it and gives you the link:
The agent's five-point summary of the result for the marketing team, ending with the link to the published report
Open the link to read the report, its evidence and its attached files on the web platform. Worked example walks through this report section by section.Then keep working in the terminal. Ask follow-ups there, and ask AIUS to update the report when the answer changes: each update is a new revision of the same report, and earlier revisions stay readable. While aius runs, you can also ask from the project page, in the AIUS panel (Your computers).
