Local AI, zero cloud
The model runs on your machine. No tokens, no per-prompt fees, no waiting on someone else's servers.
The AI assistant that lives inside Autodesk Revit.
100% local. Private. Yours.
The model runs on your machine. No tokens, no per-prompt fees, no waiting on someone else's servers.
Projects and prompts never leave your computer. Nothing to leak, nothing for anyone to train on.
Hundreds of BIM tools driven by chat — query, audit, model and document without leaving Revit.
AI transparency
Alyx is an AI assistant, not a person. Everything it answers is generated by a language model running on your own computer — one that reads your Revit model and, when you ask it to, edits it.
Treat what it produces the way you would treat work from a fast, tireless assistant who is sometimes confidently wrong: read it, check it, and never let it reach a drawing or a site without a professional reviewing it first. Alyx certifies nothing. It does not replace your judgement, your calculations or your signature.
We say this because it is true, and because it is the law: since 2 August 2026 the EU AI Act has required that a person be told when they are interacting with an AI system. We would have said it anyway.
Fair for you, sustainable for us. One licence covers Alyx in every host application it supports, works offline, and travels with you when you change machines.
Enter your key once. Your computer gets a signed, tamper-proof licence bound to that machine.
Offline, Alyx keeps working until the date you paid for. It checks in when it can; if it cannot, nothing stops.
New workstation? Release the old computer from Settings and activate the new one. Done.
One computer per licence, and you move it yourself whenever you change machines. The AI runs on your own hardware, so nothing here has tokens, per-prompt fees or a usage meter.
Pro
Alyx doing the work
$100
per year · one computer at a time
7 days free, read-only: ask, inspect, audit and report on your model with the local AI. Changes to the model start when you buy. Card required, cancel any time.
When the trial ends, or a subscription lapses, Alyx cannot be used until you activate it again. Your conversations and the files it made for you stay yours: you can open them, export them and delete them, paid or not.
Max
Pro, plus the two things Pro cannot do
$140
per year · one computer at a time · the same 7 free days, read-only
Everything in Pro — the write tools, the local AI, every update — and then:
Enterprise
Built for your office
Let's talk
Quoted per project — scope, price and a date.
Some problems do not fit inside a product. For those, we build the tool.
We are the people who make Alyx. Space Alyx S.A.C. is a Peruvian software company, and the work is C#/.NET, Python and Dynamo, inside Revit, Civil 3D and AutoCAD.
Tell us the workflow and how long it takes today. You get back a scope, a price and a date — not a subscription.

And whatever happens, your work stays yours
Alyx needs a licence to run — there is no free tier, and the 7 days are read-only. But your conversations and everything Alyx generated for you — the spreadsheets, the charts, the exports — live in your own folders and stay open to you whether you pay or not. Nothing you made is ever locked inside an app that will not open.
Pro and Max are annual subscriptions, priced in US dollars. Enterprise work is quoted and invoiced separately and is not sold through this site. Your own Autodesk licence is not included.
