Helonic is built for automating plan check on issued drawing sets. Archidian scores permit intake and sheet completeness before you file.
Helonic is the better buy when the set still needs coordination and code review. Archidian is the better buy when the only job is intake hygiene before the permit counter.
Helonic reviews the issued package for coordination and code. Archidian is organized around permit intake, title blocks, and completeness scoring.
| Feature | Helonic | Archidian |
|---|---|---|
| 2D PDF upload | ||
| Cross-discipline coordination | Not a documented focus | |
| Cited code findings | IBC, ADA, NFPA, NEC, and more | Selected IBC and ADA checks |
| Sheet completeness / title blocks | ||
| Primary job | Producer-side plan check | Permit intake hygiene |
| Procore / Autodesk RFIs | Not publicly documented | |
| AHJ-style comment preview | Not the primary job | Intake scoring |
Feature rows marked "not publicly documented" reflect Archidian's published materials as of this comparison. Confirm directly with the vendor.
Helonic is built for automating plan check on issued 2D PDFs. Archidian scores sheet completeness, title blocks, and selected IBC and ADA checks before you file. That is intake hygiene. It is not a cross-discipline coordination pass that writes RFIs into Procore or Autodesk. Helonic's code compliance check is the cited-code half of that producer-side pass.
Buy Archidian when the bottleneck is the permit counter. Buy Helonic when the bottleneck is an unread architectural, structural, and MEP package. The category ranking that includes both is software that automates plan check.
PlanCheckPro is the closer permit-preview peer. If the search was AHJ comment preview, read Helonic vs PlanCheckPro. This page is the Archidian brand query only.
Milind is the co-founder and CEO of Helonic, where he leads product and go-to-market for AI-powered construction drawing analysis. He works closely with general contractors, project managers, estimators, and owners to understand how drawing quality drives project outcomes - and where AI can reduce RFIs, change orders, and rework. Milind has interviewed hundreds of construction professionals across project delivery roles, from preconstruction estimators at ENR top-400 contractors to facilities directors at institutional owners, and uses those conversations to shape both product direction and the way Helonic talks about the work.
How this page was researched: This comparison reflects Archidian capabilities described in Helonic's 2026 plan-check category research (permit intake, sheet completeness, title blocks, selected IBC and ADA checks) set against Helonic's documented 2D PDF review, Procore and Autodesk RFI export, and code plus coordination findings. Rows without public documentation from Archidian are marked as such.
