It starts with the air.
Everything a building's climate does traces back to the state of its air. Psychro AI turns that foundation into tools, guides, and an assistant that all speak HVAC.
First principles
From the state of the air to the energy bill.
Psychrometrics describes the state of the air. It captures the heat, the moisture, and the energy held in both.
Every HVAC system exists to move that state from where it is to where a space needs it to be.
And how far it has to move it, hour after hour, is most of what a building spends its energy on.
The toolkit
A growing set of HVAC tools.
The toolkit will continue to grow.
Psychrometric chart
Plot air states from any two properties, design conditioning processes, overlay weather data, and read it all back in HVAC terms.

The toolkit will continue to grow.
The assistant
An assistant that actually knows HVAC.
Not a generic chatbot with an HVAC label. It is grounded in the fundamentals and the standards engineers actually use, and it is fluent across the tools and the writing here, so the help fits how the work is really done. When you are on the chart, it can read your state points too.
It knows the tool you have open, and on the chart, the state points in front of you. Answers fit what you are working on.
Answers lean on HVAC fundamentals and recognised standards, in the same house style as the writing.
It speaks HVAC: enthalpy, humidity ratio, sensible vs latent.
The library
HVAC engineering, worked through.
Long-form technical notes on the systems behind comfort: heat pumps, hydronics, ventilation, and the psychrometrics that ties them together. Worked examples, real numbers, no filler.
