Atlasly vs Ritn3D

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 Atlasly says its earlier REST contract has been withdrawn, its OpenAPI document has no callable operations, and the REST API is not ready for client generation.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.

Ritn3D converts 2D floor plans into interactive 3D models that users can explore, walk through, and share. It accepts PDF, JPG, and PNG plans, including CAD exports, scans, and photos of printed plans. Neural networks detect walls, doors, windows, and rooms; users can review and adjust the layout before model generation. The site says most conversions take under two minutes, depending on plan complexity. Shared models open in a browser viewer without requiring recipients to install the app or log in. The free plan includes three renders per month, a bird’s-eye view, standard textures, and sharing with up to five people. Pro costs $9.99 a month and includes 20 renders per month, walkthroughs, furniture, Full HD, sharing with up to 50 people, no watermark, and 90-day cloud sync. Pro+ costs $19.99 a month, with 40 renders and 10 GLB or STL downloads monthly; extra downloads cost $3.99 each. Free renders remain available for seven days. Each upload currently creates one floor, and hand-drawn or heavily annotated plans may need manual corrections. Ritn3D is listed for Android, iOS, web, and Windows.
