Drawing of what Data Prima does. Arrives, and is filed into the project folder: e-mail inbox, scanned mail, new documents; dictation, meetings, notes, calls. The project folder holds basic project data, sketches, documents, plans, meeting notes and all documents, and beside them the CAD model: Revit, Archicad, AutoCAD, Prima CAD. Editable for every project: guidelines, standards, rules. Office templates: plans, reports, building descriptions and everything else you want to make. All of it flows into one node, where your prompt joins, written in a small window and sent to a leading frontier AI. Safe: 100% GDPR-compliant, EU AI Act. Then you check, verify, judge: AI explains its result and names the source, and you say yes or no. The result, for example: changes in CAD, renderings, collages, documents such as descriptions and documentation, calculations, e-mails; basically everything that runs on your machine.

Made for people who work in construction planning, architecture, engineering and construction.

Data Prima revolutionizes work for industrial designers, interior designers, CAD drafters, design engineers, engineers and architects.

  • It is not stored in third countries (USA, China).

  • It is not used for training AI models.

“Our day was still 20% creative, 80% uncreative work.”

Leading architecture firm, Graz, Styria, AustriaNovember 2026

Before: 20% creative work, 80% uncreative work.

Nothing is changed without your approval.

Practical use cases.

  • Mails

    Incoming e-mails and letters are assigned to the right project, automatically or only after your confirmation. You decide. Outgoing e-mails never leave the office without your approval.

    inbox → assignment → project
    draft → approve → sent

  • Templates

    Your office’s templates are the law, for design and for content. The AI follows them, for plans, reports and everything else you make.

    template → draft → document

  • Expert reports

    Expert reports are written from your office’s own template. Every statement carries its source. For your check, you show the sources right in the finished document.

    findings → template → report

  • Building descriptions

    Building descriptions are written from the model and your office’s own template.

    model → template → description

  • Sketch to CAD

    Scanned existing plans and sketches are brought into the CAD model and can be reused as a 3D model, depending on the quality of the original without any rework.

    sketch → scan → cad model → 3d

  • CAD model changes

    Change, ask and check the model through one text field. You see every change in 3D first. It is written to the CAD only after you apply it.

    text field → 3d preview → apply → cad

  • Calculations

    Numbers come from calculations, not from the language model. Every result shows its derivation.

    values → calculation → result

Works with the CAD you have.

  • Revit
  • Archicad
  • AutoCAD
  • Allplan
  • Prima CADOur own 3D modelling tool, completely free.
“Not a single decision, idea or concept at Data Prima came from AI. It did the work though.”
