What is the difference between PlanSnapper and Datamaster?

PlanSnapper is a browser-based tool for calculating ANSI-compliant GLA from existing floor plan images and PDFs. Datamaster is a separate tool with different core functionality. The right choice depends on whether you need to measure from a floor plan or perform a different task.

Can PlanSnapper replace Datamaster?

It depends on your workflow. PlanSnapper focuses on GLA calculation from floor plans — uploading an image, tracing the perimeter, and getting square footage. If Datamaster serves a different purpose in your process, the two tools may complement each other rather than compete.

Which is better for ANSI Z765 GLA calculation — PlanSnapper or Datamaster?

PlanSnapper is purpose-built for ANSI-compliant GLA calculation from floor plan images. It handles PDF uploads, perimeter tracing, and automatic area calculation in a browser with no install required. Whether Datamaster offers equivalent GLA functionality depends on its feature set.

How much does PlanSnapper cost compared to Datamaster?

PlanSnapper and Datamaster have different pricing models — one may charge per user, per project, or via annual subscription, while the other may offer a free tier or pay-per-use option. Check the comparison table above for current pricing details and which offers better value for your volume of work.

Which is easier to use — PlanSnapper or Datamaster?

Ease of use depends on your starting point. PlanSnapper tends to fit one type of user or workflow, while Datamaster is designed for another. If you are working from an existing floor plan PDF and need to calculate square footage quickly, a browser-based tool like PlanSnapper may reduce the learning curve entirely — no software installation required.

Do I need PlanSnapper or Datamaster if I already have a floor plan PDF?

If you already have a floor plan as a PDF or image, you may not need either tool. PlanSnapper lets you upload the PDF directly and trace walls in your browser to calculate GLA — no software installation required. Both PlanSnapper and Datamaster are most useful for creating sketches from scratch or capturing measurements in the field.

Which works better for calculating GLA — PlanSnapper or Datamaster?

Both PlanSnapper and Datamaster can support GLA calculation, but the workflow differs. One may require field measurement and sketch entry while the other may allow importing existing floor plans. If your starting point is an existing PDF or image floor plan, PlanSnapper provides a faster path — upload, trace, and get the GLA figure without entering either tool's workflow.

How do PlanSnapper and Datamaster handle existing floor plan PDFs?

Neither PlanSnapper nor Datamaster is primarily designed to import and calculate square footage from an existing PDF floor plan. Both tools are built around creating or capturing floor plans from scratch. If you already have a PDF floor plan, PlanSnapper lets you upload it directly, trace the walls, and get an accurate GLA figure without redrawing anything.

Which is better for occasional users — PlanSnapper or Datamaster?

PlanSnapper and Datamaster are both specialized tools with learning curves that reward regular use. Occasional users often find dedicated subscription tools hard to justify. For someone who needs to calculate square footage a few times a month, PlanSnapper is designed for exactly that — no training required, no annual contract, upload and measure in minutes.

PlanSnapper vs DataMaster: Different Tools, Different Jobs

DataMaster and PlanSnapper are both used by residential appraisers, but they solve completely different problems. DataMaster pulls comparable sales data and helps with adjustments. PlanSnapper measures square footage from floor plan images. Here is how they differ and why many appraisers use both.

The short version

DataMaster: A data tool that pulls MLS comparable sales into your TOTAL or ClickForms appraisal report, normalizes the data, and helps you calculate adjustments. It is about comps and valuation — not measurement.
PlanSnapper: A browser-based tool for uploading a floor plan image or PDF and calculating ANSI Z765-compliant gross living area (GLA). It is about measurement — not comps or valuation.

PlanSnapper vs DataMaster: at a glance

	PlanSnapper	DataMaster
Primary function	Floor plan measurement and GLA calculation	Comparable sales data and adjustment support
Used for	Measuring square footage from an existing floor plan	Pulling comps, normalizing MLS data, calculating adjustments
Appraisal form integration	No (export PDF; use alongside form software)	Yes (integrates with TOTAL and ClickForms)
MLS data access	No	Yes (core feature)
ANSI Z765 GLA calculation	Yes	No (uses MLS-reported data)
Platform	Browser (any OS)	Windows (TOTAL / ClickForms plugin)
Price	$9 day pass / $29/mo	~$39-79/mo (varies by MLS market)

What DataMaster does

DataMaster connects to your local MLS and pulls comparable sales data directly into TOTAL or ClickForms. Instead of copying and pasting comps by hand, DataMaster populates the grid automatically -- address, sale price, square footage, bedroom count, and dozens of other fields. It also includes market analysis tools and adjustment support to help appraisers justify their adjustments with data.

For high-volume appraisers, DataMaster saves significant time on the comp selection and data entry side of the report. It is one of the most popular TOTAL plugins.

What PlanSnapper does

PlanSnapper solves a different problem: measuring GLA from a floor plan you already have. If a listing agent provides a CubiCasa scan, or you download a floor plan from the MLS package, or the client hands you an architect drawing -- PlanSnapper lets you upload that image, trace the perimeter, set a scale reference from one known dimension, and get an ANSI Z765-compliant GLA figure in under two minutes.

PlanSnapper does not pull comps, does not connect to MLS, and does not integrate with form software. It does one thing: measure square footage from a floor plan image, accurately, in the browser, with no install.

Why appraisers use both

These tools cover different parts of the appraisal workflow and do not overlap. DataMaster handles the comp side; PlanSnapper handles the measurement side.

A common workflow: use DataMaster to pull comps and populate the grid in TOTAL, use PlanSnapper to verify the subject property GLA from a CubiCasa or Matterport floor plan, then reconcile the two before finalizing the report. Neither tool replaces the other.

Already have the floor plan?

Upload any floor plan PDF or image and calculate ANSI Z765-compliant GLA in minutes. Works with CubiCasa, Matterport, iGUIDE exports, and any floor plan image.
