How PlanProof works
Follow one building project from the first drawings to years after move-in. At every step, PlanProof does the same job: it measures, it proves, and it never guesses.
Measure
Drop in the plans. Get every number, with proof.
Blueprint and AutoCAD takeoffs
Upload a blueprint PDF or an AutoCAD DXF and get a complete material list, with a quantity for every line.
The Drawings view
See your own plans with the evidence painted on — tap any number and look at exactly where it was measured.
Plan Health
If the plans aren't good enough to measure, we tell you exactly what's missing — we never guess.
Site scans for renovations
Renovating instead of building new? Scan the rooms with your phone and get measurements of what's already standing.
Buy
Know what it should cost before you spend it.
Prices and supplier quotes
Every material on the list gets a price, so your takeoff becomes a budget you can act on.
Quote Guard
Check a supplier's quote against what the plans actually show — line by line, before you sign.
Living Ledger
Write down what you commit to spend; we compare it to the estimate, trade by trade, and flag overruns early.
Pro-forma
A cost sheet you can hand a lender, where every dollar traces back to the plans.
Build
Everyone on the project sees exactly their part.
Team sides
Everyone gets their own view: the contractor sees only their trades, the customer sees progress, the lender sees money next to evidence, the architect sees plan health, and the insurer sees what the home is made of.
Schedule forecast
See how many crew-days each trade needs, so you know how long the build should take.
Walk it in AR — coming soon
Every successful takeoff already builds a true-scale model of the measured walls. The on-site AR walk-through ships once it earns the same trust as the numbers.
Live in it
The home keeps its own record, for life.
Home Record
A permanent, shareable record of what was built — the rooms, the walls, and the materials inside them.
HomeCare
A maintenance rhythm based on what the home is actually made of, not a generic checklist.
Recall watch
If a product used in the home is recalled, the record says so.
The deep end is open.
Everything above rests on an evidence chain you can inspect — nothing is a black box to you.
Adversarial proof audit
An independent pass tries to break every number before you see it; you can read each attempt.
Exact refusals
When plans aren't measurable, you get the precise reason — scale, missing schedules, unreadable sheets.
Open data
Signed exports and machine-readable output plug into your own estimating and lending systems.
When PlanProof can't prove a number, it says so instead of guessing — that's the whole point.
