Rarely am I truly impressed with the accuracy of AI. For sure AI is evolving at an exponential rate and it is amazing what AI can do, in many fields of work, compared to just a few years ago. But hallucinations and toxicity are still plaguing the true potential of AI.
However, one day I was Googling different AI's associated with various industries and I came across GRAI. GRAI is a service focused on the real estate market; it can help to plan the build, design, financing and practically anything tangentially associated the real estate market.
I provided GRAI with a few simple prompts and diagrams of a typical build, I then asked a friend who is a builder to create an estimate using the same diagrams, and the exactness of GRAI was breathtakingly accurate.
Here are the prompts I fed into GRAI and the responses.
Challenge To GRAI?
I wanted to know the estimated build cost of building an extension simply based on 2 architecture diagrams and 1 line of instructions.?
My Question To GRAI?
Using the attached architecture diagrams please tell me the estimated build cost of building an extension to my property at location (I provided a location in South England which I am not posting here for data privacy reasons)
?

GRAI Response?
To estimate the build cost for your property extension, I will analyze the architectural diagrams and take into account the following factors:?
Estimated Build Cost Calculation?
Total Estimated Build Cost?
Recommendations:?
Would you like further assistance with planning permissions, contractor recommendations, or cost optimization strategies??
?
My Next Question To GRAI?
My builder friend said he uses a cost of £2800 per metre square, so I asked GRAI to recalculate. GRAI must now understand my next question is associated with the previous question.
Can you base above on £2800 per metre square and add a drainage cost??
?
GRAI Response?
Based on a build cost of £2,800 per m2 and including additional drainage costs, here's the updated estimate for your property extension
Total Estimated Build Cost?
Notes:?
Would you like further assistance with contractor selection, drainage planning, or budgeting guidance??
My builder friend estimated the same build cost to be in range of £119,384 and £131,052.
Note, the last sentence from GRAI; GRAI is intelligently guiding the user with the next logical step. My continued conversation with GRAI continued to impress me.

2 周This was such an incredible read. Thank you, Steve Fouracre for sharing your experience in such detail - it’s always eye-opening to see GRAI being used in ways even we hadn’t fully imagined at the time of launching it. The fact that GRAI could take just a couple of plan images and produce an estimate so close to the actual builder’s numbers really reinforces why we built this in the first place - to make real estate decisions faster, clearer, and more accessible for everyone. And hearing that even professionals were taken aback by its accuracy? That’s the kind of feedback that pushes us to keep improving. AI isn’t about replacing expertise - it’s about giving people more of it, instantly. Seeing you put GRAI to the test and find real value means a lot to us. Looking forward to hearing what else you discover along the way!
