FOR TECHNICIANS

Diagnose Smarter. Not Harder.

Whether you're 2 years in or 20 — Wrench makes you faster, more accurate, and harder to replace.

Built for Every Tech

Whether You're Learning or Leading

🎓

New & Growing Techs

You're learning fast but there's SO much to know. Every car is different. Every problem has 10 possible causes. You need experience you don't have yet.

  • Don't know what normal looks like? Wrench does.
  • Not sure which PID to watch? Wrench auto-selects.
  • Afraid to call the wrong diagnosis? Wrench shows its reasoning so you can learn WHY.
  • Level up faster than techs who don't have AI backing them up.

Master Techs

You already know cars. You don't need a computer to tell you what's wrong. But you DO need speed. The faster you diagnose, the more hours you flag.

  • Skip the 30 minutes of data hunting — Wrench finds the pattern in seconds
  • Voice control — don't put down your tools to type
  • Document everything automatically — CYA for comebacks
  • Focus on fixing, not hunting. That's where the money is.
What You Get

Built for the Bay, Not the Boardroom

🧠

AI Watches Data WITH You

Start a capture, and the AI analyzes every PID in real-time. It catches the fuel trim drift, the knock retard spike, the O2 sensor that's lazy — while you're still under the hood.

📊

Confidence Levels

POSSIBLE → LIKELY → CONFIRMED. Wrench doesn't throw parts at problems. It builds a case, shows you the evidence, and lets you make the call.

🔄

Auto PID Switching

Tell the AI what symptoms you're seeing and it requests exactly the right PIDs. No scrolling through 200 parameters to find what matters.

🗣️

Voice-First

Your hands are covered in coolant. Just talk. "What's the fuel trim doing?" "Switch to misfire data." "What do you think is wrong?"

📸

Photo Analysis

Snap a picture of another scanner's screen, a wiring diagram, or a part number. Wrench reads it and adds it to the diagnosis.

Session History

Every diagnosis saved. Every data capture logged. Pull up last Tuesday's Acadia diagnosis in 2 seconds. Show the service writer exactly what you found.

Live Data Diagnosis Session
2018 Ram 1500 5.7L — analyzing hesitation...
2018 Ram 1500 5.7L, customer says it hesitates on acceleration. No codes.
No codes but drivability complaint — let's look at live data. Starting capture on Engine Basics + Fuel Trims...
📡 Auto-switching PIDs
⏱ Capture: 38.4s | 76 samples
📊 FINDINGS: STFT B1: oscillating +8% to -6% (unstable) STFT B2: stable at +2.1% (normal) LTFT B1: +11.3% (compensating lean) MAP: 14.2 psi (normal) Fuel Pressure: 58 psi (normal) The asymmetry between banks is significant. Bank 1 is hunting — the ECM keeps adjusting fuel but can't settle.
⚠️ LIKELY: Intake manifold leak — Bank 1 side
Evidence: Unilateral lean condition, fuel pressure normal rules out pump, oscillating STFT = active leak Suggested test: Propane enrichment test around Bank 1 intake runners. Watch STFT — if it snaps to 0% when you hit the leak, you've found it. Confidence: ⚠️ LIKELY (79%)
