Why architects choose local AI

Local AI, zero cloud

The model runs on your machine. No tokens, no per-prompt fees, no waiting on someone else's servers.

Your models stay yours

Projects and prompts never leave your computer. Nothing to leak, nothing for anyone to train on.

Made for Revit 2027

Hundreds of BIM tools driven by chat — query, audit, model and document without leaving Revit.

One licence, one computer — moving is easy

Fair for you, sustainable for us. Your licence works offline and travels with you when you change machines.

  1. 1

    Activate

    Enter your key once. Your computer gets a signed, tamper-proof licence bound to that machine.

  2. 2

    Work anywhere

    Spacealyx keeps working offline for weeks between quick automatic check-ins.

  3. 3

    Move when you need

    New workstation? Release the old computer from Settings and activate the new one. Done.

Choose how much Spacealyx you need

One computer per licence on every paid tier. The AI runs on your machine, so no plan has tokens, per-prompt fees or a usage meter.

  • Everything in Pro, plus:

Get Max

Pro and Max are yearly subscriptions: while yours is active you get every update, and if it lapses Spacealyx returns to the free read-only tools rather than stopping — your work is never held hostage. Free stays free with no expiry. Security and compatibility fixes reach every tier. Prices in US dollars. Your own Autodesk licence is not included.
