Show HN: We developed an AI tool to diagnose car problems

We built AutoAI – an AI tool that tells you what's wrong with your car in plain English.

Just enter:

Your car’s make/model/year

The OBD2 error codes (optional) (like P0420, P0171, etc.)

Any symptoms you're noticing (e.g. “rough idle” or “weird sound when starting”)

And we’ll tell you:

The most likely issue

How to verify it yourself

Whether it’s a DIY fix or shop-worthy

No more endless Googling or forum-hopping. Built for car owners, tinkerers, and pros who want fast, reliable answers. Powered by a repair-trained AI using real-world automotive data.

We’re trying to make diagnostics smarter, not replace your mechanic – just make you way more informed before spending money.

Would love feedback or crazy edge-case inputs to improve it.
