What you get, even on Bronze
- A Case for every problemThe symptom, the code or the quote becomes a Case. New evidence can change the answer.
- Grounded in NHTSA dataEvery diagnosis is cross-checked against recalls and owner complaints for your year, make and model.
- Your car’s recordEvery Case and repair stays on your car’s history: what worked, and what didn’t.
- Free lookups, alwaysOBD code lookup, the VIN decoder, the recall checker and quote checks never use a diagnosis.
Fair questions
- How does this compare to a shop?
- Most shops charge $80–200 just to read your codes and tell you what is wrong. RedlineAi builds a Case from your car’s evidence: the likely causes, what the evidence supports, what to check next, and parts that fit, 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, your saved diagnosis history, the VIN Decoder, Recall Checker and OBD code lookup, and one saved vehicle in the garage). Gold adds Amazon part links, shop-quote justification, step-by-step AI repair guides and an unlimited garage, with 30 diagnoses a month. Diamond adds Live OBD · Beta: plug a standard Bluetooth LE adapter into your car and see live sensor data, not just the code (real-car validation is ongoing; supported data varies by vehicle and adapter), 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 shows what the evidence supports and what is still missing before you approve a repair. 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.
