Finch vs Planix

Finch is a building-design platform for generating plans, exploring options with real-time data, and producing project outputs. Its Plan Library draws on past projects, firm knowledge, accessibility rules, local codes, and constraints as a basis for design generation. The AI agent Archie handles repetitive precision tasks such as placing doors, checking compliance, and updating linked units. Finch produces floor plans, area calculations, and BIM geometry, with exports to traditional BIM tools. It documents workflows with Rhino, Revit, Grasshopper, and Autodesk Forma; listed application versions include Rhino 8, Rhino 7.24+, Rhino 6 SR35+, and Revit 2023–2027. Finch is available as an extension and on macOS, the web, and Windows. The Free plan costs nothing for one user. Basic costs €79 a month for one user and lists a 14-day trial. Enterprise costs €14,500 a year, billed annually for at least three seats.

Planix turns a plain-English project brief into dimensioned 2D floor plans, an interactive 3D model, and preliminary engineering outputs. A mathematical solver places walls, rooms, and columns. The pipeline supplies country-aware structural defaults, a bill of quantities, a cost estimate, and engineering notes for review by a licensed engineer. Users inspect walls and openings in a browser WebGL viewport and download AutoCAD-compatible DXF and PDF files; listed export formats also include IFC, OBJ, and STL. Planix Analyze accepts IFC, PDF, DXF, Excel, image, CSV, and DWG files for preliminary structural or civil analysis. Planix Connect is a Windows desktop agent for installed AutoCAD, with AutoCAD 2018+ and Revit 2021+ compatibility listed; Revit and SketchUp support is beta. Connect does not yet support structural drawings inside AutoCAD or Revit, mixed-use buildings, or irregular plots. Files use private storage and signed download URLs. The Free plan costs nothing and allows 10 plan generations monthly.
