Every finding in the plan check panel can carry two buttons. Fix applies the change itself. Explain writes a short architect’s note on why the finding matters, in plain language.
Both are part of Pro. Explain costs one AI credit; Fix costs none.
Fix
“Fix it automatically — the change is checked against every rule before it’s applied.” That check is the point: the editor works out the change, applies it to a scratch copy, re-runs the whole plan check on the result, and only offers it if nothing else broke. A fix that solved a door swing by pushing a bed under a window would never reach you.
Fixes are ordinary edits — ⌘Z takes one back like anything else.
Not every finding has one. Some problems have too many reasonable answers for the editor to pick between, and it says nothing rather than guess.
Explain
The note answers why does this matter? — the thing a drawing cannot tell you and a rule name only hints at. It is a couple of sentences, written for this finding on this plan, and it is worth spending a credit on the ones you disagree with: either you learn something, or you dismiss it knowing what you are dismissing.
Hide the note puts it away again.
Credits
Pro includes 200 AI credits a month. Explain uses one. There is no way to overspend by accident — when the month’s allowance is gone the button says so (“Monthly AI allowance used up — more credits next month”) and nothing is charged.
What this doesn’t do
- It does not redesign the plan. Fix moves what is wrong; it does not rethink the layout. For that, see furnishing a room or generating a plan from a brief.
- It is not a code consultation. The note explains the rule Gridsnap applied, which is common residential practice, not the code where you live.
- No conversation. There is no chat — a finding, a note, a fix.
