Deck Check turns one sentence into a deck framing plan where every joist is checked by code.

Type "12 by 16 deck off the back of the house, hot tub in the right corner." Muse drafts the framing plan: deck size, hot tub zone, joist size and spacing. A deterministic span checker (simplified IRC 2021 R507.6 table, Southern Pine #2, with a load adjustment above 50 psf) marks every joist red or green. Muse then fixes only the red joists, and the checker re-verifies. Muse never approves its own work.

The model proposes. The code approves.

Demo moment: press "Add hot tub" on existing framing. The joists under the tub go red (6 failing). Muse resizes them in one fix round, and the checker confirms 6 → 0, in 2 calls and about 27 seconds. Muse then writes the cut list and a short permit note from the verified plan.

Why it matters: a deck that's fine for a barbecue can fail under a 100 psf hot tub. Deck Check makes that failure visible before anything is built.

Honesty line: this is a demo span table, not an engineering stamp. Hot tub decks need a licensed engineer.
