More context on this question
Frequently asked questions about CarShake tend to cluster around the same few concerns: is it really free, does the documentation actually hold up in disputes, how long does a scan take, and what happens when the other party denies responsibility. The short answers above cover the headline; this section gives you the deeper context that determines whether CarShake will actually work for your situation.
How CarShake actually works in practice
CarShake is a free valet-damage-proof and vehicle-handover app. The core workflow takes 60 seconds: you open the app, run a guided 8-angle walkaround scan of your car, and CarShake time-stamps and geo-locates every photo automatically. You then generate a QR handover receipt that the valet, attendant, or service advisor can scan to acknowledge the vehicle condition at the moment of transfer. When you get the car back, you run the same 8-angle scan and CarShake produces a before/after diff that isolates any new damage that appeared during the handover window.
The output is designed to be court-admissible: a clean, time-stamped, geo-located evidence packet that shows exactly when and where any damage occurred. That is the documentation that converts a he-said-she-said argument with a valet company into a resolved claim.
Why documentation timing matters
The single most important thing to understand about vehicle damage disputes is that timing is everything. Damage that occurs while someone else has custody of your car is presumptively their responsibility — but only if you can prove the condition of the car at the moment you handed it over and at the moment you got it back. Without time-stamped pre- and post-handover scans, the operator will almost always claim the damage was pre-existing or happened after you left the lot. With those scans, the dispute tends to resolve in a single conversation.
Valet damage disputes are commonly he-said-she-said without photo evidence. When damage appears and you cannot prove the car's condition at handover, the valet operator's standard defense — "it was already like that" — is difficult to refute. CarShake exists because a 60-second scan before and after handover gives you the documentation that converts an argument into a resolved claim. The free tier lets you try the workflow before committing to a paid plan.
