Check every number before it goes out.
Every quantity links to the lines it came from, assumptions cite their sheet, and checks put what needs you first. Fix it in the same workspace and the list updates.
Click a number, see where it came from.
Every quantity has a trace
Click it and the plan shows the lines behind it.
One layer at a time
Focus a layer and check it against the drawing.
Checks come first
Gaps like an opening with no header are listed at the top.

Every quantity shows its formula.
Nothing is a black box
See each input that went into a count.
Your rules, in the formula
The spacing and waste you set are the ones it uses.
Check it line by line
Follow any number from the plan to the list.
When the plans leave it open, the AI says so.
Cites the sheet
Plate heights and header notes point to where they were read.
Read from the plans
The legend, notes and sections, not guesses.
Yours to change
Fix anything that’s off and the list updates.
Ask why a number is what it is.
Ask it plainly
The way you’d ask the estimator at the next desk.
Answers with sources
Each answer points to the sheets behind it.

Ask from the same workspace you check in.
Questions about QA/QC
Who checks the takeoff?
You do. The AI drafts it and flags what needs a second look, and you approve the list before it goes out.
What do the checks look for?
Gaps in the draft, like an opening with no header. They come up first, so you start where your eye is needed.
What happens when I fix something?
Fix the trace and the material list updates. There’s no separate file to keep in sync.
Why check at all?
First drafts are typically 80–95% accurate to final quantities. AI can still get something wrong, so every number is built to be checked.
Start from a finished draft.
Upload a plan set and see the takeoff — and the proof — for yourself.
