The Smart Operating System for Auto Shops.
Intake, diagnostics, estimates, scheduling, payments. Every step a shop runs, in one AI system.
From booking to paid, in one flow.
No jumping between a scan tool, a quote app, a calendar, and a card reader. CarSignal carries the car through every step of the job.
Book & check in
Customers book online or get checked in at the counter. The car, VIN, history, and complaint open as one job.
A second set of eyes
Plug in the scanner. AI reads the codes, symptoms, and history and offers a likely fix with a confidence score. You're still running the bay.
Quote & approve
AI writes a plain-English report and an itemized quote. The customer approves from their phone in one tap.
Repair & get paid
Order parts, do the work, and keep the customer posted with auto-SMS. Invoice and collect payment in a tap.
Everything the floor needs. Nothing it doesn't.
One AI-native workflow that replaces the scan tool, shop-management software, CRM, payments, and marketing stack. Built for the shop floor.
One pipeline, every job
Every repair moves through the same lifecycle — from key-drop to paid invoice. Auto-SMS fires at each step, so the customer always knows where their car is.
Your own OBD2 scanner — built in
The CarSignal dongle plugs into any vehicle and reads deep: every module on the car, not just the engine. It pulls the VIN, codes, live data, and freeze-frame automatically — so the copilot diagnoses from real data, on any make or model.
Diagnostic copilot
Reads scan data, the customer's complaint, and the car's history — then recommends the repair, with OEM-grounded reasoning and the exact steps to confirm it.
- Load-test the battery at rest — expect a fail under load.
- Verify charging voltage 13.5–14.8V at idle.
- Re-register the new battery to the BCM, clear P0A93.
Customer-ready estimates
Every quote leads with a plain-English explanation, then itemizes parts and labor. The customer approves or declines each line from their phone.
Your alternator isn't charging the battery reliably — the warning light and a slow crank point to it. Replacing it now avoids a no-start and a tow.
Repair Buddy
AI chat grounded in OEM data for the car in front of you — torque specs, fluid capacities, and component locations, on demand.
Customers always in the loop
Every job gets a live status page — updating as the work moves, with auto-SMS at each step and two-way texting back to the shop.
Win customers back
Automated declined-service follow-ups, recall lookups, and service reminders — plus a booking page that fills the schedule. Two-way texting built in.
Runs the whole shop
Pipeline, clients and full history, scheduling, service catalog, parts and inventory, financials, and payments — the back office, handled.
Priced per shop, not per seat.

The things shops ask first.
Straight answers. If yours isn't here, a real person will get back to you the same day.
Yes. CarSignal covers intake, diagnostics, estimates, scheduling, and payments in one place, so most shops retire two or three tools when they switch.
It reads the scan codes, the customer's complaint, and the car's service history, then weighs them against patterns from similar jobs. You get a ranked list of likely causes — each with a confidence score and the specific test that confirms it. The tech always makes the call; the AI just gets them there faster.
Almost none. CarSignal walks new techs through the basics in a few minutes, and a built-in AI helper sits in the corner of every screen with full context of your shop and the app, ready to answer how-to questions as they come up.
Yes. Every shop runs in its own isolated workspace, data is encrypted in transit and at rest, and your customer records are never used to train shared models without your say-so.
We're two founders who grew up in mechanic shops. We've watched our families run the back office on paper, sticky notes, and a half-dozen apps that don't talk to each other.
Run your whole shop
on one signal.
