A plan check comment (also called a correction or redline) is an issue a building department's plan reviewer flags on your submitted construction drawings. Each comment must be resolved and resubmitted before the permit is issued. Comments typically cite a code section, missing information, or an inconsistency between sheets or disciplines. More comments mean more resubmittals, and a slower permit.
The fastest way to fewer comments is a thorough pre-submission review of the entire set, drawings, specs, and applicable codes, so issues are resolved on paper before the reviewer ever sees them. That is exactly what AI plan checking does: it flags code gaps, spec-vs-drawing conflicts, and coordination issues with evidence for each, so your team fixes them first.
