Not a prompt guessing at your building. The actual model, on the actual site.
Bring the model in from Revit, Archicad, SketchUp, or IFC. Harth works alongside your CAD, not instead of it. Your CAD stays where the building becomes precise.
Work on the real siteWork on the real site
Place the project by latitude and longitude, on 3D satellite terrain, with the surrounding buildings imported. Trace the lot boundary from the map. The agents query against that geometry, not a description of it.
Agents that read the 3D modelAgents that read the 3D model
Around forty discipline-specific skills, loaded when the work calls for them; structure and framing, envelope and thermal, interiors and space planning, analysis and compliance. Ask in plain language. The agent works on the actual elements, and you can watch it happen in the scene.
Project Research that sticksProject Research that sticks
Deep research runs inside the project and keeps what it finds. Upload PDFs, Word files, and markdown. Push a highlighted passage straight into the agent. Context doesn't reset between sessions.
Checks against the modelChecks against the model
Takeoffs, schedules, egress, and code checks, run against real geometry. Harth flags what needs a look. The architect verifies.
Build in the browserBuild in the browser
Construction mode with per-story dimensions, grid snapping, alignment and layers. Place parametric objects from the library, apply materials, edit an element inline. Nothing to install and no version conflicts.
On site, in context, anywhere in the world.
The model sits on real terrain at real coordinates, with the neighboring buildings around it. Every render comes off that geometry, so what the client sees is the building you actually drew.

The team works together. The client sees what you send.
Work side by side in the model. Comment where the decision is. Share exactly what's ready and nothing else.

Boards collect only what you choose to show.
You can build walls, slabs, and stories directly, or start from a 3D template. Most practices model in CAD and bring it in.
