Numas Field

The digital site survey for surveyors, engineers, architects and technical consultants: you survey on site, the app documents with evidentiary value, and the PDF comes out already signed.

AI report draft — with your own key

The AI module generates a draft of the technical report from your survey data. It's optional and uses your personal key (Claude, OpenAI or Gemini): no Numas subscriptions, you pay only usage to the provider. Read the guide: how to get and set up the key →
