For law firms, title companies and lenders

You receive the survey. Someone still has to read it against the commitment.

Proofle runs that comparison as a structured first pass — a checklist of 86 items, each with a one-line reason, usually one to five minutes; large surveys take longer. It runs in your browser: nothing to install. It is a first pass, not a certification — your reviewer's call is still the call.

80,000+documented corrections from sealed production surveys

Why Proofle

The standard defines what a survey must contain. Tens of thousands of surveys taught us how they fail.

Proofle is grounded in tens of thousands of sealed production ALTA/NSPS surveys and in the corrections those surveys actually required in title review: certifications that omit a party, legal descriptions that drift from the commitment, encroachment notes at odds with the drawing, monumentation and notes that contradict one another. It is refined from our own production work — never from your documents.

The result is a structured first pass in minutes, current to the 2026 ALTA/NSPS standard. It is the same check a surveyor runs inside Civil 3D before delivery. Its accuracy is measured every week against an experienced reviewer's rulings on real surveys and printed on every report, and every finding states its basis.

What it reviews

Where surveys actually go wrong

Proofle reviews the survey and title commitment against a checklist derived from documented corrections — not merely the published standard — across the full ALTA/NSPS requirements and the Table A items you select. Among the areas it examines:

Survey requirements

Table A items: The optional Table A items you selected for the survey — checked in scope.
Basis of bearings: That the basis of bearings is stated and consistent with the survey.
Flood zone: That the flood note identifies the zone and the FEMA panel and community.

Title cross-checks

Certification: Whether the certification names the parties it should, including the title insurer.
Schedule B exceptions: That title-commitment exceptions are addressed and dispositioned on the survey.
Legal description: Flags potential mismatches between the legal description and the title commitment for your review.

Drawing details

Monumentation: That boundary corners are monumented and the monumentation is noted.
Encroachments: Presence of the encroachment statement when it's called for by scope.
…and more: Surveyor identity and licensure, scale and north arrow, adjoiners, access, and the rest of the checklist.

Each item resolves to FAIL, RECOMMEND, PASS, or N/A with a short, plain-language reason — surfaced for your review, never decided for you.

Zone, panel number and date are given, but the note does not expressly state that the property is not located in a Special Flood Hazard Area; add that sentence.

How to trust it

Built to assist your judgment — and to respect your data

Proofle is built on a single premise: a structured first pass, with the professional's judgment governing every determination.

An aid, not a replacement

Proofle provides assistive first-pass review only — not a substitute for licensed professional review. Every finding is a prompt for professional judgment: you confirm, dismiss, or correct each one, and independently verify every output. Where the document does not support a determination, the item is returned for your confirmation rather than decided.

Your documents aren't retained

Documents are processed and not retained. They are never used to train or improve SI models.

Your drawing is never modified

Proofle reads your survey to review it. It never writes to, edits, or alters your drawing — the review is delivered as a separate report, and your file remains exactly as you saved it.
