How it works
Describe the problem
Tell TechAssist Pro what you're working on. Snap a photo of the nameplate, error display, or problem area — the AI sees what you see.
Follow exact steps
TechAssist Pro identifies the equipment and walks you through diagnosis — one numbered step at a time, with the exact tool, setting, and expected reading for each check.
Fix it. Save it.
Root cause identified, fix applied, system back online. Every resolved session is saved as a reusable procedure you can reference on future calls.
Not a chatbot. A field mentor.
Every response tells you which tool to grab, which setting to use, where to probe, what the reading should be, and what it means when it's wrong. Built for techs working alone in tight spaces.
Sequence of operations
Knows the exact startup and shutdown sequence for each system — not generic advice, the real SOO for that specific make and model.
Tool-specific instructions
Tells you which meter to grab, what mode to set, where to place the probes, and the expected reading range.
Adaptive diagnosis
Adjusts the next step based on what you report. Wrong reading? It pivots to the most likely cause and narrows down from there.
Photo and video analysis
Snap a photo of the nameplate or the problem. The AI identifies the equipment and incorporates what it sees into the diagnosis.
Session history
Every resolved session is saved. Review past diagnoses, reference successful fixes, and track your growth across system types.
Gets smarter over time
Every resolved session improves the system. The more technicians use it, the faster and more accurate it becomes for everyone.

If your industry is automating, the trades are hiring. Electricians, HVAC techs, and plumbers are in record demand — and there aren't enough of them. You don't need a 4-year degree. You need reps. TechAssist Pro gives you reps.

What techs are saying
I used TechAssist Pro on a VRF system I'd never touched before. The AI walked me through the entire commissioning — step by step, with the exact readings I should expect. Fixed it in one visit.
Marcus T.
HVAC Technician, 6 years
I went from zero trade experience to passing my EPA 608 in 4 months. I study on TechAssist Pro every night. It explains things the way a patient mentor would — not a textbook.
Sarah K.
Career changer, former retail manager
My journeyman showed me the app and now I use it on every service call. The photo analysis is wild — I snapped a pic of a tankless water heater error code and it told me exactly what to check.

Is this replacing trade school?
TechAssist Pro accelerates your learning. Real techs use it during apprenticeships to diagnose faster, pass exams sooner, and earn more in their first year. It's not a replacement — it's an unfair advantage.
Do I need any tools or equipment to learn?
No. Learn mode teaches you through conversation, scenarios, and quizzes. You don't need any tools, equipment, or prior experience to start. When you're ready for hands-on work, the AI tells you exactly which tools you'll need.
Does this work on my phone?
Yes. TechAssist Pro works on any phone, tablet, or computer — no download required. Add it to your home screen for a native app feel, or use it directly in your browser on the job site.
Can I use this on an actual job site?
Yes. Diagnose mode is built for exactly that. Take a photo of the equipment nameplate, describe the issue, and the AI walks you through step-by-step troubleshooting with specific tool instructions.
What's the difference between Free and Pro?
The 7-day free trial gives you full Pro access with no card required. After the trial, Pro is $29.99/mo — or $19/mo forever if you're one of the first 200 founding members. Pro includes unlimited diagnose sessions, photo and video analysis, voice mode (hands-free), live camera feed, and saved procedures.
How does the 7-day free trial work?
No credit card required to start. You get full Pro access for 7 days. If you continue, you're charged after the trial ends — at the founding rate of $19/mo if spots remain, otherwise $29.99/mo. Cancel anytime before day 7 and you're never charged.
