Questions
I'm not a mechanic — can I still use this?+
Yes. That's who Wrenchify is built for. Type the code your scanner showed, or just describe what the car is doing, and you get the likely causes and how to check each one in plain English. No shop manual required.
Do I need a credit card to start?+
No. The free Driveway plan stays free — sign up with email or Google and you're in.
What do I get for free?+
5 full lookups a month (trouble codes, symptoms, or step-by-step how-tos), 2 saved vehicles, VIN camera scanning, 3 Bluetooth scans, service reminders, and real recall and service-bulletin checks from NHTSA. Weekend Wrench is $4.99/mo for 40 lookups and 10 vehicles; invoicing starts on Pro Tech.
Is it useful if I already turn wrenches for a living?+
Yes. Trouble codes (DTCs), factory service bulletins (TSBs), open recalls, flat-rate labor hours, and customer invoices are all in one place, on your phone, in seconds.
Can I switch plans later?+
Yes. Upgrade or downgrade anytime; changes take effect the next billing cycle.
How accurate is it?+
Diagnostics come from a large AI model tuned to factory-style repair procedures. Recalls and service bulletins are pulled live from NHTSA, not generated by AI. Always verify against the vehicle in front of you.
