Cheaper than one trip to the shop.

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.
How many diagnoses do I get?
Each plan includes a set number of AI diagnoses per month, which reset on the 1st, plus a one-time bonus batch the first time you reach that tier. The bonus is used before your monthly allowance. Looking up an OBD code and checking a repair quote are always free and never count against it.
What is the difference between the plans?
Bronze is free (5 diagnoses/month, owner mode, follow-up chat on every diagnosis, the VIN Decoder and Recall Checker, one saved vehicle in the garage, and free OBD code lookup). Gold adds saved diagnosis history, Amazon part links, shop-quote justification, step-by-step AI repair guides, an unlimited garage, advanced Code Lookup and advanced vehicle data (specs + torque values), with 30 diagnoses a month. Diamond is built around the Live OBD reader — plug into your car and see your engine’s live sensor data in real time, not just the code — with 100 diagnoses a month. The Shop plan (for shops & mechanics) adds the Shop & Tech Advisor diagnosis modes, labor-cost estimates, unlimited diagnoses and team seats.
Is there a Family plan?
Yes. Gold and Diamond each offer a flat Family plan — one subscription that covers up to 3 people. Gold Family is $15.99/mo with 45 shared diagnoses; Diamond Family is $28.99/mo with 150 shared diagnoses. Every member gets the full tier features and everyone draws from one shared monthly pool. Family plans bill monthly. Pick "Family" on the Gold or Diamond card above to get started.
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.
