Atlasly vs Planix

Atlasly provides early-stage site intelligence for architects, including first-pass screens of planning, flood, heritage, and related constraints. Its floor plan generator turns prompts into schematic 2D concept diagrams for ideation, not construction drawings. The free tool allows three generations per day without signup; free outputs are PNG, while DXF and DWG exports require an account. Atlasly says automated reports generate PDF site packs in under 60 seconds. Walkability AI provides pedestrian-network isochrones, four persona presets, weighted amenity categories, site comparisons, and GeoJSON, Shapefile, and SVG exports. Users can access Claude and ChatGPT through Atlasly’s hosted MCP server, and a Forma Site Design extension is listed. Atlasly says its earlier REST contract has been withdrawn, its OpenAPI document has no callable operations, and the REST API is not ready for client generation. The Starter plan is free, while Professional is £15 a month billed annually and Teams is £159 a month billed annually; both paid plans include a 14-day trial. Atlasly is a product of Parallel Labs Ltd, which works from Manchester, United Kingdom.

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.
