The AI operating system for auto shops.
Intake, diagnostics, estimates, scheduling, payments. Every step a shop runs, in one AI system.
Your whole floor, on one board.
Every car in the shop, its next step, and the money attached.
Book a demo to see it on your own cars.
Every handoff stays connected.
Everything you just clicked is one record. The complaint becomes the diagnosis, the diagnosis becomes the quote, and the approved quote becomes the job, without anyone retyping the story.
One job. One signal.
Every handoff updates the floor and the customer automatically, from check-in to collected payment.
Diagnostic copilot
Feed it the codes from whatever scan tool you already run. It weighs them against 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 that updates as the work moves, with a text at each step and two-way texting back to the shop.
Meet the AI workforce.
Four AI agents, on shift around the clock.

The things shops ask first.
Straight answers. If yours isn't here, book a demo: see it live and ask anything.
Yes. CarSignal covers intake, diagnostics, estimates, scheduling, texting, and payments in one place, so most shops retire two or three tools when they switch.
It takes the juggling off their plate, not their job. CarSignal absorbs the phone tag, the booking back-and-forth, and the appointment handling that eats a service writer's day, and every conversation lands in your console where the team can step in anytime. Your front desk gets its time back for the customers standing right in front of them.
Migration is free and done for you: customers, vehicles, and history come over, and CarSignal runs alongside your current system until you're ready. Nothing gets ripped out on day one.
The same day. Create the shop, set your hours and labor rate, and you can check in your first car in minutes, with the booking page, texting, and payments included. Data migration from another system happens in the background while you work.
It reads the trouble 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.
No. CarSignal works with the scan tool you already own: enter the codes and the diagnostic copilot takes it from there. Check-in reads the VIN or plate with your phone camera, no extra gear. A direct plug-into-the-car connection is on our roadmap.
Yes. Techs get a mobile app for the bay: their jobs for the day, photos straight into inspections, and status updates that move the board in real time. The desk and the floor stay on the same page without anyone walking a clipboard around.
Nothing goes to a customer without a human deciding it should. Diagnoses are recommendations your tech confirms, quotes are drafts you review before sending, and every AI message the receptionist sends is visible in your console the moment it happens.
Yes. The AI receptionist picks up calls and texts on your shop's own number: after hours, when the counter is slammed, or full-time if you want. It answers real questions, captures the lead, and books the appointment; anything it can't handle lands on your board with the full conversation attached.
No. Your shop gets its own registered business line (or keeps texting from the number customers already know). Conversations are two-way: when a human takes over the thread, the AI steps aside.
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, and it's the full shop in your pocket, not a stripped-down tech app. Check cars in with the camera (plate or VIN scan), build and send quotes, order parts, take payments, and watch the floor from anywhere.
Parts ordering runs through PartsTech (your existing supplier accounts and pricing), payments through your own Stripe account, and paid invoices sync to QuickBooks. Your shop keeps its relationships; CarSignal does the typing.
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.
No contract, cancel anytime, and your data is yours: customers, vehicles, history, and invoices export cleanly. And the first 30 days are guaranteed: if we haven't won your shop over, every fee is refunded and we move your data back, free.
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.
