Evaluate a plan built with another tool
A core function of the engine is symmetric: the same rules that generate a house can grade one you already have. Bring a floor plan — drawn by hand, exported from another app, or found online — and the engine models it and tells you how it holds up: code issues, tight clearances, and where it departs from best practice.
Shown below on published designs the app may legally model — Jay Osborne's open-source farmhouse designs (freefarmhouse.com, CC BY-SA 4.0) and public-domain classics like the 1928 Home Builders Catalog. Each card is our model of the published plan, credited to its source — not the original drawings, and not one of our generated designs. Reader confidence flags how faithful the model is.
Evaluate your own plan
Upload a 2-D floor-plan drawing — PNG, JPG, WebP, GIF, or PDF — or paste a link to one. The AI reader models it (coarse rooms + connectivity, never a copy of the artwork), then the engine grades the model against the same cited rules as everything else here.
Your file is read once and never stored. Results are advisory and only as good as the reader's model of the drawing — check its footprint + room list before trusting the scores.
