AI role (our label)AI-firstAI-first
What it doesAI construction drawing analysis platform whose spec-analysis feature reads the full project manual (CSI MasterFormat Divisions 00-49, also the older 16-division format and SectionFormat 3-part specs, including MasterSpec and SpecLink-based books) alongside the drawing set and flags spec-vs-drawing conflicts: material mismatches, finish and hardware schedule vs spec section discrepancies, equipment vs performance specs, items specified but not drawn and drawn but not specified, fire-rating and acoustic mismatches, referenced sections or standards that do not exist, Division 01 requirements not reflected on the drawings, and incomplete submittal requirements. Each finding cites the spec section and sheet with a severity rating (vendor description). The vendor's FAQ says the AI flags candidate issues and the spec writer decides; it describes the AI as strongest on quantitative cross-references and weakest on intent. Pricing page lists Procore integration that pushes issues as RFIs, custom checklists and on-premise deployment on higher tiers. The spec page's spec-writer anecdote is labeled by Helonic as synthesized from interviews, so we do not treat it as a customer quote. Vendor says it is backed by Y Combinator.AI plan check for construction drawings and specs: code compliance (e.g. IBC, ADA, IECC, plus uploaded local ordinances), cross-discipline coordination, spec-vs-drawing conflicts, and constructability. Findings are prioritized by severity with sheet snippets and code references. The vendor states AI findings can be wrong or incomplete and should be verified. Vendor-stated turnaround: usually hours, same day.
