Construction drawing checker found 28 of 30 planted errors in 10 minutes

One drawing sheet can stand for 4 identical floors. The bill priced 1.

Mistakes like that hide in every construction drawing package, and someone has to find them by hand before a firm can quote. For a landscape package, that's about 2 weeks.

So I built Landsight.

You drop the developer's folder in as it came: CAD drawings, scans, Excel bills, backups. It gives every file a verdict, counts and measures what's drawn, and checks the bill against the drawings, the firm's price list and the building code. Then it drafts the change request and the reply to the developer.

Every number traces back to the drawing it came from, and nothing counts until a person confirms it.

We planted 30 errors in a sample package. It found 28, flagged 2 for a person and missed none. About 10 minutes instead of 2 weeks.

Under the hood:
- Muse Spark 1.3 reads what geometry can't settle and writes the prompts SAM 3.1 uses to measure colour plans.
- Muse Wonder learns each firm's habits.
- And because drawings are under NDA, there's a private mode on Muse Spark Open, Meta's open weights, with the same result.
