What the Desktop App Is

The Stru AI Desktop Client connects your Stru AI account to the engineering software already installed on your machine. With the desktop app running, the ETABS and SAP2000 agents build and analyze models directly in your own licensed copies of the software, on your hardware, with your files.

Works with your licenses

Drives the SAP2000, ETABS, and Mathcad installations you already own. Nothing extra to license.

Paired with your account

One sign-in connects the desktop app to the same conversations, files, and agents as app.stru.ai

​
Requirements

  • Windows with SAP2000 and/or ETABS installed in their default locations (C:\Program Files\Computers and Structures\...)
  • A Stru AI account
  • An internet connection: the app connects to Stru AI each time it starts
macOS support is on the way. Today, agent-driven SAP2000/ETABS work runs on Windows.

​
Install

1

Download the installer

Download the latest Stru AI Desktop Client Setup (.exe) from the releases page.
2

Run the installer

Run the downloaded file and follow the prompts. The app launches when installation completes.
3

Let it set up your environment

On first launch, the app prepares its working environment automatically. You’ll see a “Setting up your environment” progress screen. This one-time step typically takes about a minute.
If setup can’t finish (for example, the connection dropped), restart the app. It picks up and retries automatically.

​
Sign In

1

Click Log In with Stru AI

The app opens your default browser to authorize the sign-in.
2

Authorize in the browser

If you’re already signed in at app.stru.ai, authorization is instant. Otherwise, sign in as usual. The browser shows a confirmation page when the desktop app is authorized.
3

Return to the app

The desktop app picks up the sign-in automatically, with no codes to copy. You land directly in the chat workspace.
The sign-in window stays open for 5 minutes. If it lapses, or the browser never returned to the confirmation page, click Try Again in the app and complete the browser step again.
Sign out from Settings → General → Account → Logout. If the app returns you to the sign-in screen on its own (for example, after an extended time away), sign in again. Your conversations and settings are safe.

​
Staying Up to Date

Updates download automatically in the background. When one is ready, an Update button appears in the header. Click it and the app restarts on the new version in a few seconds. You can also check your current version anytime under Settings → Software → Check for updates.
If SAP2000 or ETABS is running under Stru’s control when you update or quit, the app asks for confirmation first, because updating closes that session. Save your model in SAP2000/ETABS before continuing. If you don’t respond, the app proceeds automatically after about 10 seconds.
