Features

Everything a Tech Needs. In Your Pocket.

AI-powered diagnostics, live vehicle data, and voice control -- built for the bay, not the boardroom.

Tap Code, Get AI Diagnosis

Read a DTC, tap it. Wrench auto-reads related sensors, correlates live data with the code, and tells you exactly what's happening -- with confidence levels and cost estimates.

8-Module OBD Scanner

Scans PCM, TCM, ABS, BCM, SRS, IPC, HVAC, and TPMS. Select which modules to scan. Visual topology map shows every module at a glance.

Voice-Controlled

Full hands-free diagnostics. Talk to Wrench with earbuds under the hood. It listens, diagnoses, and speaks back. Built for greasy hands.

Live Data + Graphing

Stream PIDs in real-time. Record data, tap any reading to see trend graphs with min/max. Auto-alerts when values go critical.

Pre/Post Scan Reports

Insurance-ready reports with one tap. Every module scanned, codes found, freeze frame data, and what changed between pre and post repair.

Service Resets

Oil life, TPMS relearn, throttle relearn, battery registration, brake pad reset, and more. Bi-directional controls built in.

Emissions Readiness

Check all readiness monitors in one tap. MIL status, DTC count, every monitor. Know if it'll pass before you send it.

Community Fixes

"What actually fixed this code on this exact car?" Real techs sharing real fixes. Crowdsourced and growing with every diagnosis.

Freeze Frame + Recalls

Auto-reads freeze frame data when codes are found. NHTSA recalls and complaints load automatically alongside your codes.

LIVE AI DIAGNOSIS

AI That Watches the Data With You

Other scanners read codes. Wrench analyzes your live data stream in real-time and tells you what's actually wrong — with evidence.

🔧
Live AI Diagnosis
Real-time analysis in progress...
2012 Acadia 3.6L, won't rev past 2500 RPM, stalls
Starting capture on VVT/Timing data...
📡 Switching to VVT / Timing PIDs
🚨 CRITICAL FINDINGS:
  • Knock Retard: 18.6° (normal: 0-3°)
  • All 4 cams frozen — not responding to ECM commands
  • Engine in protection mode — limiting RPM
⚠️ LIKELY: VVT system failure
Next: Check VVT solenoid oil screens for debris
What about timing chain?
Chain stretch would show gradual retard on both banks equally. Your data shows sudden freeze with normal oil pressure. More consistent with VVT actuator failure than chain stretch.

Confidence: ⚠️ LIKELY (78%)

What Makes It Different

Watches Live Data
AI analyzes your data stream in real-time during capture, not after
📊
Confidence Levels
POSSIBLE → LIKELY → CONFIRMED. No premature diagnosis
🔄
Auto-Switches PIDs
AI requests the exact data it needs and the scanner switches automatically

Our Story

Built by a Shop Owner, for Shop Techs

Every feature exists because a real tech needed it on a real job.

Built in the Bay, Not in Silicon Valley

Wrench was born in a repair bay in Manlius, New York -- not a Silicon Valley conference room. Built by a shop owner who got tired of clunky, overpriced diagnostic software designed by people who have never turned a wrench.

After years of watching techs waste time walking back and forth to the shop computer, digging through forums, and fighting outdated interfaces, the answer became obvious: build a smart co-pilot that lives in your pocket.

No fluff. No bloat. No features dreamed up in a boardroom.
