What Data Prima does.

What Data Prima doesAlong one axis arrive the e-mail inbox, scanned mail and new documents, and dictation, meetings, notes and calls. They are filed into the project folder: basic project data, sketches, documents, plans, meeting notes, all documents, and inside it the CAD model (Revit, Archicad, AutoCAD, Prima CAD). Along the second axis come the guidelines, standards and rules, editable for every project, and the office templates for plans, reports, building descriptions and everything else you want to make. At the node your prompt joins from a small window, sent to a leading frontier AI. Safe. 100% GDPR-compliant, EU AI Act. Before anything leaves: you check, verify, judge. AI explains its result and names the source, and you answer yes or no. Out comes the result: for example changes in CAD, renderings, collages, documents (descriptions, documentation), calculations, e-mails; basically everything that runs on your machine.Basic project dataSketchesDocumentsPlansMeeting notesCAD modelRevit, Archicad,AutoCAD, Prima CADProject folderall documentsDictationMeetingsNotesCallsE-mail inboxScanned mailNew documentsarrives and is filedinto the project folderEditable forevery projectGuidelinesStandardsRulesOffice templatesPlansReportsBuilding descriptionsand everything elseyou want to makeYour prompt|Leading frontier AISafe. 100% GDPR-compliant,EU AI Act.You check, verify, judge.AI explains its resultand names the source.whysourcethe resultfor exampleChanges in CADRenderingsCollagesDocuments: descriptions, documentationCalculationsE-mailsBasically everything thatruns on your machine.

Your prompt

Leading frontier AI

Safe. 100% GDPR-compliant, EU AI Act.

You check, verify, judge.

AI explains its result and names the source.

the result

for example

  • Changes in CAD
  • Renderings
  • Collages
  • Documents: descriptions, documentation
  • Calculations
  • E-mails

Basically everything that runs on your machine.

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

100% safe data.

You own your data.

  • Files stay on your office’s own machines.

  • Folders are indexed, not copied.

  • Client data never goes through consumer AI subscriptions.
  • It is not stored in third countries (USA, China).
  • It is not used for training AI models.

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

Practical use cases

  1. 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

  2. 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

  3. 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

  4. Building descriptions

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

    model → template → description

  5. 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

  6. 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

  7. 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.
