Free AI Car Damage Detection App & Auto Repair Estimator
Carithm is a free AI car damage detection app and photo estimator. Upload a picture of a dent, scratch, cracked bumper, broken light, or damaged wheel and our AI vehicle damage assessment tool flags the visible damage, then gives you a ballpark US repair cost range in about five seconds. No account, no email, and no native app to install: this auto repair estimate AI tool runs directly in your iPhone (iOS), Android, or desktop browser.
Before you call a body shop or an insurer, you mostly want to know whether this is a $150 problem or a $1,500 one. That's what this is for.
One honest caveat up front: it reads photos, not X-rays. It can't see what's happening behind the panel, and that matters more than you'd think.
- No account, email, or signup
- Works on iPhone, Android, and desktop
- Built around US repair pricing

How the AI car damage scan works
- Take or upload a photoDaylight works best. Get the whole damaged area in frame.
- The AI looks for visible damageDents, scratches, cracked bumpers, broken lights, cracked glass, and wheel or tire damage.
- You get a US repair cost rangeA ballpark based on what the photo shows. The range is wide on purpose, because real quotes vary by shop, region, and what's behind the panel.
What our AI car damage recognition tool can spot in a picture
Depending on how clear the shot is, the vehicle damage scanner can usually pick out:
- Dents and dings: from a shopping cart tap to a proper hail-damaged hood. Our AI dent detection catches both.
- Scratches, key marks, and scuffs: including paint transfer and clear-coat damage for automotive scratch detection.
- Cracked or chipped glass: the kind of windshield chip that's cheap now and expensive in six weeks.
- Broken headlights and taillights: cracked lenses, hanging brackets, that sort of thing.
- Cracked bumpers: your standard fender-bender collision damage estimation.
- Bent or creased body panels: doors, fenders, hoods, and quarter panels.
- Wheel and tire damage: flats, curbed rims, obvious bends.
That's the visible stuff. The less visible stuff is where things get more interesting, and it's worth reading before you trust any number, including ours.
How much does car damage repair cost? US ballparks by damage type
Here are rough US ranges for common damage. Treat them as a sense of scale, not a quote.

Why two similar-looking dents cost differently
A dent is not a dent. Two cars can roll into the shop with what looks like the same ding and walk out with very different bills, depending on:
- Paintless dent repair vs. conventional repair: if the paint isn't cracked, PDR is usually far cheaper.
- Panel replacement vs. repair: sometimes it's genuinely cheaper to replace a panel than fix it.
- Aluminum vs. steel: aluminum panels generally cost more to repair.
- Paint blending: matching a modern metallic or pearl finish often means blending paint into the panels next to the damage, not just the damaged one.
- OEM vs. aftermarket parts: original manufacturer parts cost more than aftermarket equivalents.
- Sensors and cameras: a bumper hiding a parking sensor or camera adds recalibration cost on top of the bodywork.
- Local labor rates: shop rates vary a lot by region, and that alone can shift a quote by hundreds of dollars.
What a photo can't tell you
Here's the annoying part about auto body damage: a lot of the cost isn't in what you can see. A bumper can look like a $300 scuff-and-buff and turn into $1,200 once the shop pulls it off and finds a cracked mounting bracket or a parking sensor that's no longer sitting where it should.
Things a photo genuinely cannot show you:
- Bent structural components behind the visible panel
- Broken mounting brackets or clips
- Parking sensors or cameras built into a damaged bumper
- Whether ADAS calibration will be needed after the repair
- Damage to the bumper's internal foam or reinforcement bar
- Mechanical or alignment issues from the same impact
None of that makes the estimate useless. It just means it's a floor, not a ceiling. If the shop's quote comes in higher than what you saw here, that's not automatically a red flag. It might mean they found something the camera couldn't.
How to take a car damage photo the AI can read
The estimate is only as good as the photo, so a few things help a lot:
- Shoot in daylight or good indoor lighting. Hard shadows and glare hide damage and confuse the read.
- Get the whole damaged area in frame, not just the worst-looking inch of it.
- Take one close-up of the damage and one wider shot showing where it sits on the car.
- Keep it in focus. A blurry photo of a bad dent reads worse than a sharp photo of a bad dent.
- Don't crop out the surrounding panel. Context matters for judging severity.
- If the damage wraps around a corner or spans two panels, take a couple of angles.
When people use an AI car damage checker
Someone hit my car in a parking lot
You want to know roughly what you're looking at before you decide whether it's worth chasing down insurance info, filing a claim, or just paying for it yourself. The estimate gives you something to work from. It won't tell you who's at fault or settle a dispute. That's still a conversation with insurance or the other driver.
I scraped my bumper
Bumper scrapes are deceptive. The plastic itself is often the cheap part. The clips, brackets, and anything mounted behind it (sensors, cameras) can quietly add hundreds of dollars. If your scrape is near a sensor cluster or camera housing, budget for the possibility that it's more than a scuff-and-buff.
Checking whether a body shop's repair quote is fair
Run a photo of the damage through the estimator and compare the range to the quote. If the numbers are in the same neighborhood, that's a reasonable sign the quote is fair. If they're far apart, ask the shop what's driving the difference. It's usually hidden damage, paint blending, or parts priced OEM instead of aftermarket. An itemized estimate (parts, labor hours, paint, calibration) makes that conversation easy.
I need photos for an insurance claim
Claims generally go smoother with the same handful of shots: one wide shot showing the whole car, a mid-range shot of the full damaged panel, and a close-up of the damage itself. Take them in good light, then run the close-up through the estimator to see whether the damage is anywhere near your deductible before you decide to file.
I'm buying a used car
This is where I'd be more cautious. A photo estimate can flag obviously repaired panels, like mismatched paint, uneven gaps, or overspray, but it can't prove prior collision history on its own. Pull a vehicle history report and, if anything looks off in person, have a body shop or independent mechanic take a real look before you buy.
I'm returning a rental car
Practices vary by company and location, but it's a good habit to photograph the car yourself before you hand back the keys: timestamped, all sides, close-ups of anything questionable. If a damage charge shows up later that you don't recognize, your own documentation puts you in a much better position to dispute it.
Free consumer damage scanner vs. enterprise inspection software
Search for AI vehicle damage detection and many of the results are built for insurers, dealerships, and rental fleets, sold by contract or per inspection, often as an AI car damage detection API or SDK. Carithm sits at the other end: a free, consumer-facing auto repair estimate AI tool for one car, one photo, and one ballpark.
If you run a fleet or a claims operation, you'll want purpose-built vehicle damage assessment software with structured reports, vehicle damage tagging, and audit trails. If you just want to know whether a dent is worth worrying about, this photo estimator is the quicker route.
When to just get it looked at in person
Some situations are worth skipping the estimate and going straight to a shop or mechanic:
- The damage is near a sensor, camera, or badge cluster on the bumper or grille.
- The car pulls to one side, or anything feels different after the impact.
- There's a warning light on the dash that wasn't there before.
- You're buying the car and the seller can't explain a repaired-looking panel.
- The damage is anywhere near a wheel well, suspension component, or the frame rail.
A photo can't settle any of that. It just tells you where to point a professional.
Frequently asked questions
Is this AI car damage estimator free?
Yes. No account, no email, no catch. Upload a photo and get a free AI car damage detection estimate and rough repair range with nothing to sign up for.
Is there an AI car damage detection app, or do I need to download anything?
No download needed. This auto repair estimate AI tool runs directly in your browser on iPhone (iOS), Android, and desktop. On a phone you can pick a photo from your gallery or take a new one with your camera.
Can a photo actually tell me how much my repair will cost?
It can give you a reasonable range based on what's visible. It can't account for hidden damage, so treat it as a floor rather than a final number.
How accurate is AI car damage detection for small dents and scratches?
It depends mostly on the photo. Clear, well-lit, in-focus shots of the whole panel work best. Shallow dings on curved glossy panels, hairline scratches, and dark paint in harsh sun or glare are hard for any camera-based system, and for the human eye too. If a read looks off, retake the photo from another angle in softer light and compare.
Can the AI detect windshield, headlight, and wheel damage?
Yes, when the damage is visible: cracks and chips in glass, cracked or broken light housings, curbed or bent rims, and flat tires. It can't tell whether a windshield chip will spread or whether a replacement will need camera recalibration.
Can the AI see damage underneath the bumper?
No. It only reads what's in the photo. Anything behind the plastic, such as brackets, sensors, and structural components, is invisible to it, same as it would be to you looking at the car.
Why is my estimate different from the body shop's quote?
Usually it's hidden damage the shop found once they got hands on the car, or a difference in parts pricing (OEM vs. aftermarket) and local labor rates that a photo can't factor in.
How can I check whether a body shop's repair quote is fair?
Upload a photo of the damage to get a ballpark, then compare it with the quote. If they're in the same neighborhood, the quote is probably reasonable. If the shop's number is much higher, ask for an itemized estimate covering parts, labor hours, paint and blending, and any sensor recalibration, and consider a second quote.
Should I repair the dent or replace the panel?
That depends on the panel's condition, material, and how the paint is holding up. It's a call best made by a shop that can see the damage in person, not from a photo alone.
Can I use this before filing an insurance claim?
You can use it to get a sense of whether the damage is worth claiming versus paying out of pocket. It's not something you can submit to an insurer as an appraisal.
Should I file an insurance claim for minor damage?
If the repair estimate is close to or below your deductible, paying out of pocket is usually cheaper, and a claim for minor damage can raise your premium for several years. How much depends on your insurer and state, so check your policy before deciding.
Can I use this to check a used car before buying?
It can flag obvious signs like mismatched paint or an odd panel gap. It can't confirm or rule out prior accident history, so pair it with a vehicle history report and, ideally, an in-person look.
Why does a small-looking dent sometimes cost so much?
Usually paint. If the clear coat is cracked or the color needs blending into neighboring panels to match, that can cost more than fixing the dent itself.
What happens if I damage a rental car?
Rental companies bill you for new damage found at return unless it's covered by a damage waiver, your personal auto insurance, or credit card protection. Photographing the car yourself before you return it helps document its condition.
