What’s New Version 3.13.1
Improved model reasoning performance.
Description
Your AI mechanic, running entirely on your phone.
Ask any car question and get instant, accurate answers grounded in a curated automotive database covering 400+ vehicle models from 1976 to 2025.

The AI model now ships inside the app. No more download setup on first launch open the app and start asking questions immediately.
Pick your trim when setting up a vehicle (STI, Si, SS, Type R, etc.) and the AI uses it to surface engine-specific specs and procedures instead of generic model-level answers. A WRX STI now gets EJ257 answers, not blended WRX content.
IMPROVED:
- Smarter underlying AI model with better diagnostic reasoning
- Cleaner vehicle database
- Vehicle picker now shows your saved cars first for one-tap re-select
