RedlineAi vs OBD Vault

Your car just threw a check-engine light. RedlineAi tells you what's wrong, what it costs to fix, and whether you can do it yourself — before you ever set foot in a shop. RedlineAi turns your phone into a professional-grade OBD-II scanner and pairs it with AI that actually explains what your codes mean. No mechanic markup. No guesswork. LIVE OBD-II SCANNER Plug in any Bluetooth LE OBD-II adapter and read your check-engine light in seconds: - Stored, pending, and permanent trouble codes (P, B, C, and U) - Live engine data — RPM, speed, coolant temp, engine load, throttle, intake air - Your VIN, communication protocol, and battery voltage - One-tap export or share, plus a demo mode to try with no adapter INSTANT AI DIAGNOSIS Every code is matched to a clear, plain-English diagnosis: the most likely cause, an honest repair-cost estimate, what to check first, and exactly where to buy the part. RECALL CHECKER Enter your VIN and instantly see open safety recalls for your exact vehicle — so you never miss a free factory fix. YOUR GARAGE Save every vehicle, track service history and mileage, and get reminders before maintenance is due. Never miss an oil change again. COMPLETE CODE LIBRARY Look up any OBD-II trouble code, explained in plain language — severity, symptoms, common causes, and typical fixes. ASK AI ANYTHING Chat with an AI mechanic about any noise, warning light, or repair quote and get a straight answer in seconds, day or night. STEP-BY-STEP REPAIR GUIDES For DIY fixes, follow clear instructions with the tools, parts, and time you'll need — and keep the labor cost in your pocket. FAIR-PRICE ESTIMATES See what a repair should actually cost in your area before you walk into a shop, so you never overpay again. Works with common BLE OBD-II adapters (Vgate iCar Pro BLE 4.0, Veepeak BLE+, and similar). A Bluetooth Low Energy ("Bluetooth 4.0") OBD-II adapter is required for live scanning and is sold separately. RedlineAi is built for everyday drivers. Diagnostic guidance is informational and doesn't replace a certified mechanic for safety-critical repairs. Stop guessing. Start driving with confidence. Download RedlineAi today.

OBD Vault reads vehicle data through a compatible ELM327 Bluetooth Low Energy (BLE) or Wi-Fi/TCP OBD-II adapter. An adapter and a vehicle are required for live readings and new scans. Bluetooth Classic adapters are not supported on iPhone. Available readings depend on your vehicle, ECU and adapter. Wi-Fi recording requires OBD Vault to remain open with the screen on; it pauses when you leave the app or lock the screen. You can keep the Live Data screen open while recording. SCAN AND UNDERSTAND Read confirmed, pending and permanent diagnostic trouble codes, supported sensor readings and emissions readiness information. Review stored freeze-frame data when the ECU provides it. Code explanations and suggested checks are guidance; they do not identify a confirmed root cause or certify that a vehicle is safe to drive. LIVE DATA AND TRIPS View supported live readings such as engine RPM, speed and coolant temperature. Record trips, review distance and sensor history, and keep diagnostic scans separate from trip records. View ECU-reported fuel flow when supported, or an estimate when the required readings and fuel profile are available. Recalculate estimated fuel use for saved trips when the necessary sensor history was recorded. VEHICLE PROFILE When VIN is unavailable, optionally select your make, model and engine before your first scan. Search an offline catalog of 433 makes and 10,871 models. Engine choices are tied to the selected model and show capacity, fuel and available power. Manual entry remains available for missing variants. YOUR HISTORY, OFFLINE Save scans and trips on your phone without an account. Review saved history locally. File export requires active paid access. Clearing fault codes is a separate manual action that requires confirmation and shows the ECU response. VEHICLE PLANS, CLOUD AND YOUR OWN AI Local scanning, live data and history for one vehicle are free. Paid plans cover a total of 1, 3 or 10 vehicles and include cloud synchronization, access from your own AI assistant through Model Context Protocol (MCP), and file exports. Choose monthly, annual or lifetime access. Monthly and annual subscriptions renew automatically until canceled in your store account. Lifetime is a one-time purchase. Current prices and purchase terms are shown in the app. Sign in to synchronize saved records across devices. Your external assistant and account must support adding an MCP connector; set up that connection separately in your assistant. The app shows setup guidance after your first successful scan. OBD Vault does not run an AI model, and its connector cannot send commands to your vehicle. OBD Vault supports standard OBD-II diagnostics and selected manufacturer-specific control units and readings where a supported reference is available. Coverage depends on your vehicle, ECU and adapter. It does not provide comprehensive manufacturer coverage, ECU coding or active tests. It is not a replacement for inspection or advice from a qualified technician. Vehicle data by VehiclesDB (vehiclesdb.com).
