Frequently asked
How does this compare to a shop?
Most shops charge $80–200 just to read your codes and tell you what is wrong. RedlineAi gives you a grounded diagnosis — likely cause, what to check, cost range, and where to buy the part — starting free on Bronze.
What is a credit?
One credit = one AI diagnosis. Each plan includes a set number of credits per month that reset on the 1st, plus a one-time bonus the first time you reach that tier. Bonus credits are used before your monthly allowance.
What is the difference between the plans?
Bronze is free (2 diagnoses/month, owner mode, free OBD code lookup). Silver adds saved history, Amazon part links and the Recall Checker. Gold adds the Garage, VIN Decoder and advanced Code Lookup. Diamond unlocks Shop & Tech Advisor modes and the live OBD reader (plug into your car) with live sensor data inside diagnoses.
Is RedlineAi accurate?
Every diagnosis is cross-checked against real NHTSA recall and owner-complaint data for your exact year, make and model, and comes with an honest confidence score. It is AI-assisted guidance, not a replacement for inspection by a licensed mechanic on anything safety-related.
Can I cancel anytime?
Yes. Subscriptions can be cancelled anytime — you keep full access until the end of your billing period, then move to the free Bronze plan. Annual plans save roughly 16–17% versus paying monthly.
