Data & Methodology
Every pAIsa estimate is built on real DFW supplier prices, field-tested labor rates, and 2,400+ historical projects. Here is exactly where our numbers come from.
Stone & Material Data
227 Stones from 6 DFW Suppliers
We do not estimate stone prices — we know them. Our inventory pulls real per-ton pricing from six regional quarries and distributors that supply the DFW outdoor living market.
Noles Enterprises
32 stone varieties · Central Texas
Alliance Materials
53 stone varieties · North Texas
Whiz-Q Stone
64 stone varieties · Oklahoma & Texas
Vaquero Stone & Supply
44 stone varieties · DFW Metro
Big Tex Stone
21 stone varieties · South Central Texas
Outdoor Warehouse Supply
13 stone varieties · DFW Metro
How we maintain accuracy: Stone prices are updated when supplier catalogs change. Each stone entry includes quarry source, per-ton price, color analysis (via Claude Vision), and compatibility tags. When a stone is discontinued, pAIsa automatically suggests alternatives from the same supplier and price tier.
How We Calculate
Three AI Agents, One Estimate
Every estimate runs through three specialized agents that work in parallel. Each agent has a single job and its own data sources — no one agent guesses at something another agent knows.
Pricing Agent
Calculates material costs, labor rates, stone tonnage, appliance pricing, and permit fees using live DFW supplier data.
227 stones, 39 appliances, 27 city permit schedules
Design Agent
Validates stone-to-home compatibility using color theory, regional style trends, and aesthetic conflict resolution.
Style guide RAG, color palette matching, stone pairing rules
Social Agent
Benchmarks your estimate against real DFW market data — what your neighbors are building and what they paid.

Avg Project Value
Example: When a Keller homeowner asks for an outdoor kitchen estimate, pAIsa already knows that 53% of Keller projects use Lueders Buff stone, the average project costs $17,159, and the most active neighborhoods are Hidden Lakes and Marshall Ridge. This context makes every estimate locally calibrated, not generic.
