AI on the Job Site: What Field Techs Actually Want

There is a persistent gap between what gets built for the trades and what tradespeople ask for. The requests are consistently more boring and more useful than the roadmap.

What gets asked for

"Just tell me the number." Not an essay. Not five options with caveats. The number, and where it came from, so it can be checked.

"Work without signal." Said in some form by nearly everyone. Basements, mechanical rooms, rural service calls. A tool that fails offline fails at the exact moment it is needed.

"Let me photograph it." Nameplates, error codes, control boards, panel interiors. Typing a model number correctly with cold hands is genuinely difficult, and the information needed is written right there on the equipment.

"Don't make me log in again." Session expiry on a rooftop is a small disaster.

"Tell me when you don't know." This one comes up more than expected, and always from experienced techs. They have been burned by confident wrong answers and would rather have an honest gap.

What does not get asked for

Voice assistants. Job-site hardware. Anything described as an agent. AR overlays.

Some of that may arrive eventually. None of it is the current bottleneck, and building it first means shipping something impressive that does not get used on Tuesday morning.

The apprentice pattern

The use we did not anticipate: senior techs handing the app to apprentices.

Not to replace teaching — to answer the fifteenth "why" of the day so the senior tech can keep working. And critically, to give the apprentice a way to check themselves before asking, which builds judgement faster than being told.

This changed what we optimise for. An answer that explains the reasoning is more valuable than one that just states the conclusion, even though the conclusion is what was asked for.

What this should change

If you are building for the trades, the implications are unglamorous:

• Offline capability is a core feature. Design for it from the start; it is very hard to retrofit.
• Photo input is not a nice-to-have. It is often the fastest path to the right answer.
• Brevity is a feature. Long answers are read as noise.
• Refusals build trust. Every honest "I cannot tell you that without a measurement" earns credibility for the answers you do give.
• Ship the calculators. They get used more than the AI, and they are the thing that works when everything else does not.

The pattern underneath all of this: tradespeople are not skeptical of AI because they are behind. They are skeptical because they are accountable for the outcome. Build for accountability and adoption follows.
