A lot-size number can include the roof, driveway, and patio. Review the actual lawn in your service scope, with available parcel lines for context and maintained grass outside the parcel identified separately.

FOR PEST CONTROL BUSINESSES
Put lawn area behind the outdoor estimate.
Use reviewed lawn square footage as one input to outdoor pest-control estimates. Confirm the areas included in the service; lawn area is not the same as a building perimeter or every treatment surface.
Review it. Adjust it. Come back to it.
Rate a result and correct its polygons when an edge is off. Reopen the measurement in your property history before the next estimate or service conversation. Shadows, trees, and older imagery can affect the result; an aerial estimate does not replace field verification or confirm a legal boundary.

Scores reflect outline agreement on one user-corrected property, not surveyed accuracy or a guarantee. *Gemini Pro used a larger output budget.
The takeaway
Astra and Gemini Pro scored similarly in this small test. Astra completed maps sooner under its tested settings, so it remains our current choice. Every measurement still benefits from a quick human review.

How we scored it & full results
The quality index is mean polygon overlap with the corrected outline, expressed on a 0–100 scale. It measures shape agreement only—not speed, reliability, or real-world accuracy. An 82.9 score does not mean 82.9% measurement accuracy. This internal study was run by OpenLawn and has not been independently audited.
Astra and Opus include both their initial and repeat reference runs. Other scored models have one reference run. Astra ranged from 75.2 to 90.7; Opus from 75.1 to 76.2. These observed ranges are not a confidence interval. Different settings and unequal repeat counts limit comparisons.
Each model received the same saved aerial, parcel, mapping prompt, drawing tools, parser, and area calculation. Corrected polygons were withheld; no SegFormer hints were used. The prompt was developed for Astra. The initial configuration used medium reasoning and 2,400 output tokens per turn. Gemini Pro's scored configuration used 8,192 tokens; its initial configuration did not finish. Astra low-reasoning runs are kept in the full results, not mixed into this chart.
Astra's initial mean model-pipeline time was 46.4 seconds; Gemini Pro's adjusted mean was 123.9 seconds. These timings exclude address lookup, queueing, browser rendering, and saving. Provider load and cache warmth were not controlled.

Failures, compatibility retries, and all repeat runs remain in the download. Only one property has a corrected reference, and none have surveyed ground truth. Inputs and full artifacts are not public, so this is not a fully reproducible public evaluation.

A FEW GOOD QUESTIONSBefore your
Before your
next estimate.
What is OpenLawn?
OpenLawn is AI lawn measurement software for lawn care and pest control businesses. Enter a customer property address, review mapped lawn square footage, and save the measurement to support estimating and service planning.
Who is OpenLawn built for?
OpenLawn is built primarily for lawn care and pest control businesses that need lawn-area estimates for customer properties. Owners, estimators, and service teams can review the mapped area before using it to inform their own quotes and service plans.
How do I measure a customer property online?
Create an OpenLawn account, enter the customer property address, and select the right match. The agent loads the aerial and available parcel boundary, then outlines lawn regions and calculates an estimate. Review the mapped areas and confirm the intended service scope before using the result.
Is lawn area the same as lot size?
No. Lot size includes the house, driveway, sidewalks, patios, beds, and other surfaces. OpenLawn maps grass rather than treating the entire parcel as lawn. Street-side service grass and inferred maintained extensions may be outside the parcel and should be reviewed separately.
How accurate is AI lawn measurement?
Accuracy depends on image resolution and age, shadows, tree cover, address placement, and parcel alignment. OpenLawn provides a reviewable estimate, not a guaranteed accuracy percentage. Check the overlay and verify important measurements on site. Our published model benchmark is a small internal comparison, not independently surveyed accuracy.
Does OpenLawn work in the United States and Canada?
OpenLawn accepts U.S. and Canadian addresses. Our parcel dataset covers the United States; Canadian measurements use visible property features where parcel data is unavailable. Aerial detail varies by location. An inferred working outline is an estimate, not a verified property line.
How many free lawn measurements do I get?
Every new account receives five free AI lawn measurements, with no credit card required. The allowance is shared across that account’s devices and workspaces. A completed AI analysis uses one measurement; model failures return the reserved credit. Reopening saved results does not use a measurement.
Can I use it for lawn care estimates?
Yes. Use reviewed lawn square footage as an input to mowing and lawn-care estimates, then apply your own pricing. Check exclusions, access, slopes, obstructions, and service requirements separately. OpenLawn measures lawn area; it does not calculate the final quote for you.
Can pest control businesses use OpenLawn?
Yes. Pest control teams can use reviewed lawn square footage as one input when estimating outdoor services. The current workflow maps lawn, not building perimeter length or every possible treatment surface. It does not identify pest activity, recommend products, calculate application rates, or generate treatment plans.
Can I correct an AI lawn measurement?
Yes. Review and rate the completed measurement. If areas were missed or included incorrectly, use the polygon correction controls to adjust the mapped lawn and review the revised estimate.
Which AI model does OpenLawn use?
Agent View uses GPT-6.1 Sol by default for lawn mapping. After a completed Sol measurement, you can remeasure the same property with GPT-6 Astra using another measurement credit and compare the saved results. Both models combine aerial imagery with available parcel context and draw reviewable lawn polygons. Model output is an estimate.
Can another AI agent use OpenLawn?
Yes. Install the OpenLawn skill in an agent that supports SKILL.md instructions and browser control. It guides the agent through the signed-in address-to-measurement workflow and reading saved results. It uses your OpenLawn account and the same measurement allowance.
