36 findings from 14 public sources
The #1 finding on record here
How it works
Three steps, about a minute.
Step 1
Enter an address
We find it on the map, then pull sixteen public data sources live: flood maps, the national traffic noise model, contamination lists, permits, transit, 311 reports, and more. You watch each source answer.
Step 2
Get six scores
Every finding is weighted into six scores from 0 to 100: noise, light, change, hazards, connectivity, and pulse. Plus the three things you are least likely to know already. No overall score, on purpose: the report informs your decision, it doesn't make it for you.
Step 3
Keep the record
You get a share link and a print-ready PDF. The six scores and the top finding are free. One payment unlocks everything. No account, no subscription.
What's inside

Questions
Answered plainly.
Where does the data come from?
Every layer is a public record: FEMA flood maps, EPA contamination and air quality lists, the government's national traffic noise model, OpenStreetMap and federal rail and airport data, Census housing facts, MBTA schedules, and Boston's permit, development, 311, and police report feeds. Every finding cites its source and the date we pulled it. Check the bottom of the sample report.
How accurate is it?
Honest answer: as accurate as the public record it cites, and we show our work. Noise figures are modeled estimates, good for spotting problems, not measurements. So we always pair them with real distances to the actual road, rail line, or runway. Every finding shows when its data was pulled. Flood findings link to FEMA's own map viewer so you can double check the zone yourself. A report is information for your decision. It is not an inspection, an appraisal, or a guarantee.
What's deliberately not in a report?
Anything that scores a neighborhood by who lives there. We never score, filter, or phrase findings on protected classes. Census data is used for housing facts only, like building age and renter share, and incident reports appear as rates with context.
Where does it work?
Any US address gets the core checks: flood risk, contamination, air quality, radon, modeled traffic noise, nearby airports and rail crossings, walkability, and housing facts. Reports go deepest in Greater Boston, where we have the most local records: building permits, planned development, 311 complaints, police reports, and MBTA transit. Where a check doesn't cover your address, the report says "not checked here" in plain sight, never hidden.
What does it cost? Do I need an account?
$19, once, per address. The six scores and the top finding are free before you pay. No account. The report link is yours, and the PDF comes with it.
Why is there an hourly limit on new reports?
Groundtruth runs on free public data services from agencies like FEMA, the EPA, and the Census Bureau. To stay a good citizen of those services, each visitor can generate 3 new reports per hour. Reports you already generated stay available at their links.
What if the report tells me nothing new?
You'll know before you pay. The six scores and the single most important finding are free, so you can see whether the record holds something worth knowing before spending $19. If the free preview shows nothing useful, you've spent nothing.
