Gav's Customs
AI Car Diagnostics
Describe what your car is doing, out loud. Check Engine listens and tells you what's likely wrong, whether it's safe to drive, and roughly what the repair costs.

Tap once and talk the way you'd talk to a friend in the garage — "there's a clicking when I turn", "it shakes over sixty". No mechanic vocabulary required. Stop talking and it answers within a few seconds, out loud, in a real human voice — with big karaoke-style captions that light up word by word as it speaks. The whole conversation stays on screen, and the mic opens again on its own, so it's a back-and-forth rather than a search box.
On first launch it asks how mechanically inclined you are, from 1 ("where's the hood latch?") to 10 ("I rebuild engines for fun"), and pitches every answer to that.
A plain verdict — safe, drive with caution, or do not drive — never buried in hedging.
A rough US repair range, so you know roughly what you're walking into.
When a fix needs them, Tools and Parts buttons appear — every part linked to a search you can shop.
Checked against the NHTSA public database for your year, make and model.
Type a code like P0301 and get what it means, how serious it is, and how it's fixed.
Every diagnosis saved on your device, so you can look back at past repairs.
