Contractor Quote Checker — AI Material Analysis
Paste your contractor's quote and let AI compare the material quantities and line items against standard construction benchmarks. Catch overpriced materials, missing items, and quantity errors before you sign.
How the Quote Checker works
- 1Paste the full text of your contractor quote
- 2AI extracts every line item: material, quantity, unit, and price
- 3Each quantity is compared against MaterialCalc benchmarks for your project type
- 4Pricing is checked against typical supply-chain ranges
- 5A summary flags overages, underestimates, and missing items
Example: 20 m² bathroom tile quote
Quote lists 22 m² porcelain tile @ €38/m², 5 kg adhesive, no grout or waterproofing membrane.
AI flags: tile quantity correct (+10% waste), adhesive severely underestimated (need ~55 kg for large-format tile), grout and membrane missing entirely — typical oversights that add €180–320 to final cost.
Frequently asked questions
What types of quotes can I check?
Tiling, flooring, painting, drywalling, decking, concrete work, and general renovation. The checker works best when the quote lists materials with quantities and unit prices.
Is my quote data kept private?
Yes. Quotes are processed securely and stored anonymised (no names, addresses, or contractor details). Aggregate data is used only to improve MaterialCalc benchmarks.
How accurate is the AI analysis?
The AI is a sanity-check tool, not a certified estimate. It catches common quantity errors and obvious pricing outliers. Always get a second human opinion before signing a large contract.
Do I need an account to use it?
You can run one free check without an account. Sign in to run unlimited checks and save your results to a project.
Can it check prices in my local currency?
The checker uses relative benchmarks (e.g. "price per m² is 2× typical range") rather than absolute prices, so it works in any currency.
