Evidence over conclusion
A finding with no source wording is a guess. Each line in the report points back to the sentence in the quote it came from, so the homeowner can verify it before signing.
ScopeCheck compares trade quotes line by line
An AI-assisted quote comparison product for UK homeowners: add two to five quotes for the same job and get one report showing what each includes, what is missing and what to ask the trader — before paying a deposit.

01 / Challenge
The problem worth solving.
Getting several quotes for a home job is easy; choosing between them is not. One trader includes VAT, another adds it later; one lists scaffolding, another leaves it out. The difference is usually only visible after the deposit is paid.
02 / Approach
From ambiguity to a working system.
- 01
Built intake around the quotes people already have: pasted text, PDFs or up to four photos per quote, with a free two-quote preview that needs no account.
- 02
Checked every quote against the homeowner's own saved job list rather than against the other quotes, so the shortest quote is not automatically read as the cheapest.
- 03
Tied each finding to the exact wording in the source quote, with assumptions and unclear tax treatment flagged instead of resolved silently.
- 04
Separated quoted prices from the estimated cost of missing work, then benchmarked totals against named, dated UK price guides where a suitable reference exists.
- 05
Shipped the commercial layer: guest previews, one-off paid plans taken through Paddle, PDF export and read-only report links that can be switched off.
03 / Technical decisions
Never adjust a price
VAT is labelled included, added on top, not charged or not stated. Quotes on different bases are flagged rather than quietly equalised, so the comparison stays auditable.
Paid only by the homeowner
The product takes no commission from traders, so a report has no commercial reason to soften what it finds.

05 / Constraints
What the demonstration does not claim.
- ScopeCheck does not find traders, inspect the property, certify work or give legal, tax or surveying advice.
- Estimated costs of missing work are benchmarked from published UK price guides, not trader offers, and are not guaranteed savings.
- An AI model reads the quotes and can misread a page or miss a detail, so the source wording and the trader's written answer remain the record.
- The report shown here is illustrative — trader names and details are changed.
