Stori3D is a 3D building studio that runs in the browser. Design a building here, from the first wall to the drawing set, or bring in the model you already have from Revit, Archicad or SketchUp. Then send your client one link: they walk round the model, pin comments on the spot and step inside in VR, with no account and no app.

What's inside:

- Walls that join, rooms that measure themselves, and parametric doors, windows, roofs and stairs

- Plans, sections and elevations from the model, on sheets with your title block, issued as one PDF

- Grids, beams, ramps, lift shafts and parking bays for flats over a car park

- Path-traced renders on your own graphics card, with no render credits

- Walkthrough tours, scroll stories and MP4 video for presenting

- Live co-editing for teams, everyone with their own undo

- IFC in and out, and DXF or PDF drawings to trace over

- Works with Claude, Codex, Cursor and other AI tools over MCP

Built on a forked three.js editor, WebGPU with a WebGL fallback, and Firebase, with an open MCP server (stori3d-mcp on npm).
