What would you like to know first?
What is ArchX?
ArchX is the AI agent for architecture practices, on Mac and Windows. Give it the task and the project files: it reads drawings and documents, measures, compares tenders, builds 3D models and saves finished, editable files in your project folder. The UK edition adds planning, Building Regulations, tendering and JCT contract administration, in British English.
How is an agent different from a chat?
In a chat you get an answer and still do the work yourself. ArchX gets the task and the files. It opens the documents, works through every step and saves the result: comparison, drawing, model, schedule, minutes or letter.
How do I try ArchX?
Download ArchX for Mac or Windows and connect your ChatGPT account (Plus or higher) or your own API key from OpenAI, Anthropic, Google, Mistral or xAI. The 7-day free trial starts automatically, without payment details.
What does ArchX cost?
£169 a month for your practice, including the first person; each additional person £42 a month. Yearly: £1,690 and £420 per additional person. Prices exclude VAT. AI usage runs through each person’s own ChatGPT account or API key.
Does ArchX work for practices in Scotland, Wales and Northern Ireland?
Yes. Drawings, tenders, documents, 3D models, minutes and project reviews work for any project. The planning and Building Regulations workflows follow the rules for England, and Wales with a clear notice; for projects in Scotland and Northern Ireland, ArchX works from the sources you supply.
Where do our project files go?
ArchX runs on your computer and works in your project folder. The content a task needs goes to the AI provider you connect: your ChatGPT account or your API key.
What happens in the 20-minute demo?
We share our screen and run ArchX on a real architecture task: files in, finished results out. Tell us which work holds your practice up the most and we show you ArchX on a similar job. The demo is free and comes with no commitment.
