# The nameplate, read from a photo.

The technician photographs the nameplate. Brand, model, serial number and refrigerant are read by AI, and the equipment is found or created in your database.

What goes wrong today

## One serial number copied wrong, and everything else follows.

- References are copied by hand, often with a mistake.
- The nameplate photo exists, but nobody links it to the equipment.
- Your equipment database ages: unknown models, duplicates, units on the wrong site.
- When quoting, the exact part cannot be found.
- Refrigerant tracking needs information nobody recorded.
- Unknown equipment means a technician goes back.

The demo · example, fictitious data

## A nameplate photo, an up-to-date equipment record.

Pick a nameplate. On the right, what the tool reads and what it does in your database, with what a person must decide when the plate is damaged.

Demonstration with fictitious data. At your company, the tool writes into your equipment database.

How it works

## From photo to record, no copying.

01

### Photograph

The technician takes a photo of the plate, even at an angle or with glare.

02

### Read

AI reads brand, model, serial number, year, refrigerant and capacity.

03

### Match

The tool finds the equipment in your database, or proposes a new record.

04

### Flag

Anything unreadable or ambiguous goes to a person instead of being guessed.

What it costs you

## Your reports have a cost. Work it out.

Technicians, jobs per week, minutes of writing and re-typing: the calculator gives you an order of magnitude in hours and euros per year.

Free · no commitment

## A written plan, for your company.

Tell me which documents slow you down. I'll send back the two or three worth automating, and the shortest path to a tool that runs.

Thank you, received. I'll reply within two business days.

Frequently asked

## What people ask me before we start.

### What if the plate is damaged or dirty?

The tool reads what is readable and flags the rest. A person completes or chooses, and the correction stays on the record.

### Does it work for every brand?

Reading works on what is written on the plate, whatever the brand. Matching with your database is tuned to your equipment during the diagnostic.

### Where does the information go?

Into your equipment database and the service report. The prototype shows it alongside; writing into your software is built afterwards.

### Who has it already?

An HVAC company with around twenty technicians: nameplate reading is part of the mobile app, which also works offline.
