Photograph anything that looks off.
A crack in drywall. A door that sticks. A grout line that won't behave. Anything. Don't think about whether it "counts."
A house is alive. In its first twelve months it loses water, shifts foundations, and learns the climate. Some of that movement is normal. Some of it is warranty. Most homeowners can't tell the difference — until it's too late to file.
The same vision model that runs in the mobile app, embedded right here. Drop a photo of any crack, gap, pop, or stain — the model returns a verdict in 3–5 seconds with case, severity, warranty section, and a drafted claim letter.

We built this around the only tool homeowners actually have on hand: their phone. Take a picture. Drop a pin on the floorplan. We do the rest — classification, timeline, draft warranty language, and a record your builder can't pretend not to receive.
A crack in drywall. A door that sticks. A grout line that won't behave. Anything. Don't think about whether it "counts."
Drywall crack vs. settlement crack vs. structural. Cosmetic vs. claim-worthy. Confidence scores, not vibes.
Your house, top-down. Every issue lives at a spot, at a date. Re-photograph the same spot in a month — we'll align them for you.
We draft the warranty language, attach the evidence, time-stamp the submission. Your builder gets a record. You get receipts.
We designed for the moment you actually notice the problem: standing in your hallway, phone in hand, wondering if it's nothing or something. Tap the shutter. Watch the model think. Get an answer you can act on.
Runs in any browser. Installs to your home screen as a PWA.
Below is the live HBR mobile PWA running in an iframe — same code that ships to your phone. Tap a room, capture a photo, run the 9-stop walkthrough, watch the AI verdict come back. Nothing is faked.
Camera capture works on a real phone via the device camera. On desktop it falls back to a file picker.
No menus. No nested folders. The way you think about your house is room-by-room — so that's the navigation. Click a room to see every photograph, every note, every issue you've recorded there. Tap a marker to open the record.
Photograph a crack today. Photograph it again in 90 days. We align the two images, measure the change, and tell you whether it's stabilizing, drifting, or accelerating. This is the evidence builders can't argue with — and the homeowner usually doesn't have.

Width 11 mmAnyone can be friendly at closing. We measure what happens after — how many claims a builder receives, how fast they respond, how often they fix it right the first time. The data is real, attributable, and built from the same homeowners who actually live in the houses.
Honest builders love this. The rest of the industry will too, eventually.
— from the founders
Twelve years later I still remember the sound the floors made the first dry winter. Wood that had been green-stamped 17% moisture content was, by February, somewhere south of 8%. A house that had been plumb and tight in summer was suddenly full of small honest gaps. None of them were anyone's fault. Some of them were.
Telling those two categories apart took a contractor friend, a structural engineer cousin, and a stubborn afternoon with calipers. Most people don't have those friends. Most builders count on it.
We built Homebuilder Review because the technology finally exists to give every new homeowner the eye of an inspector and the memory of a clipboard — without either. Take the picture. The model knows the difference. The timeline does the rest.
The same evidence that gets a claim acknowledged voluntarily is the evidence your state's contractor licensing board, the Better Business Bureau, and (in the worst case) a small-claims judge will ask for. HBR's record — dated photos, same-spot progression, warranty-section citation — is built to be admissible. Most builders honor the warranty when they see the paper trail. A few don't; for those, the paper trail is what wins.
Yes. Vision models miss things and over-call things. We surface confidence on every classification, show the three checks that drove it, and tell you when the photo is too dark or too far away to be reliable. We bias toward "watch" over "claim" on the boundary — re-photographing is free; a false claim is expensive social capital with your builder. When confidence is below 75%, we say so out loud.
Yes, but the warranty math is different. Interior fit-and-finish is yours; common-area structural is the HOA's. HBR labels each defect with the warranty section it falls under, so you know which ones you can file yourself and which need to go through the board. We don't (yet) auto-route to your HOA's portal — file copies are on you.
Photos and addresses live encrypted at rest on Cloudflare R2 in a bucket your account owns. AI inference happens against the Anthropic API; we don't train on your images. You can export everything as a single PDF + ZIP at any time, and delete the account in two clicks. HBR is not for sale to your builder's insurance company. Ever.
You should — at the 11-month walkthrough. HBR isn't a replacement for a human inspector at the high-stakes milestones; it's the continuous record you keep between visits, so your inspector arrives with a year of photographs instead of a blank pad. Inspectors love HBR users. They walk in with 80% of their findings already pre-categorized.
Only when you file a claim. HBR doesn't notify your builder otherwise. When you do file, the letter is sent from your email address with the photos attached — your builder sees a thoughtful, well-documented homeowner, not a notification from an AI service.
