Where it wins
- Plain-language prompts produce dimensioned 2D plans and interactive 3D models
- Engineering workbooks, quantities, and code-aware checks extend beyond layouts
- DXF, IFC, PDF, OBJ, and STL exports support design and 3D workflows
Where it doesn't
- The free tier is limited to 10 plan generations per month
- Outputs are preliminary and require professional review before construction
- Web-only access may not suit desktop-first design teams

Our verdict on Planix

Planix is a web-based architecture tool for architects, engineers, drafters, and self-builders. Users describe rooms, plot size, orientation, and country in plain language, then receive a dimensioned 2D floor plan, an interactive 3D building model, a preliminary structural layout, engineering notes, quantities, and cost estimates. Chat-based modifications support iterative design changes, while upload-based preliminary engineering analysis extends the workflow beyond initial planning.

Planix uses a freemium model. The free tier provides 10 plan generations per month, making it accessible for early concepts, feasibility work, and experimentation with prompt-based planning. The product also includes a Pro plan. Its web delivery keeps the core workflow browser-based, while Planix Connect provides local CAD control for teams that need a closer connection to CAD processes. Export support covers DXF and IFC for CAD and BIM workflows, along with PDF, OBJ, and STL for documentation and 3D use.

The standout feature is the combination of conversational design changes with engineering-oriented outputs. A single project can move from plain-language requirements to a floor plan, 3D model, preliminary structural layout, bill of quantities, and engineering workbook. Code-aware checks and country input add useful context, but the results remain preliminary and need professional review before construction or permitting. Planix suits users who want a free starting point with technical outputs; teams requiring final engineering approval, construction documentation, or a desktop-first environment should choose a more specialized tool.
