Helonic vs Structured AI

PDF-first analysis for construction teams vs BIM-centric QA/QC for design engineering firms, different tools for different roles.

Quick summary

Choose Helonic if:

You work primarily with 2D PDF drawings
You are a GC, owner, or subcontractor
You need Procore and Autodesk field integration
You want proprietary AI built for construction drawing accuracy
You need to generate RFIs from findings

Choose Structured AI if:

You are a design engineering firm using Revit
You need QA/QC directly inside BIM workflows
You want the AI to learn your firm's standards
You need document automation (Word, Excel, SharePoint)
SOC 2 compliance is a hard requirement today

Key differences

These platforms serve fundamentally different roles in the construction lifecycle. Structured AI, backed by Y Combinator, positions itself as an "AI workforce for construction design engineering." It lives inside the BIM environment, Revit, Word, Excel, SharePoint, and automates QA/QC for design engineering firms. Helonic is built for the teams that receive those drawings: GCs, owners, and subcontractors who need to review 2D PDFs quickly and push findings into field tools.

The BIM vs PDF divide is the fundamental split. Structured AI thrives when your team works in Revit and needs QA/QC automation during the design phase. It can learn your firm's specific standards and flag deviations automatically. Helonic works with the output of that design process, the 2D PDF drawing sets that get issued for construction. Most GCs and subs never touch a Revit model; they work from PDFs, and that is where Helonic operates.

Custom standards vs proprietary AI validation represent two different philosophies. Structured AI learns your firm's specific drafting standards and checks against them. Helonic takes a different approach: its proprietary AI model was built specifically for construction drawings, trained to detect coordination conflicts, code violations, and cross-discipline issues. One approach is about internal consistency; the other is about comprehensive issue detection.

Field integration vs design integration. Helonic connects to Procore and Autodesk for downstream workflows, turning findings into RFIs, syncing with project management. Structured AI integrates upstream into Revit and Office tools for the design production process. They occupy different positions in the project timeline.

Frequently Asked Questions

I work in Revit all day. Should I use Structured AI instead of Helonic?

If you're a design engineer producing drawings in Revit, Structured AI is purpose-built for your workflow, it integrates directly into your BIM environment and learns your firm's standards. Helonic is designed for the teams reviewing those drawings after they're issued as PDFs. Many projects benefit from both: Structured AI in design, Helonic in construction.

Can Helonic work with BIM models?

Helonic is optimized for 2D PDF analysis and does not directly process Revit or IFC models. This is intentional, most GCs, owners, and subcontractors work from issued PDF drawing sets, not live BIM models. If you need BIM-native QA/QC, Structured AI is the better fit for that specific use case.

Could a team use both Helonic and Structured AI on the same project?

Yes, and it could make sense for large projects. The design engineering firm could use Structured AI to QA/QC their Revit models and documents before issuing drawings. The GC could then use Helonic to review the issued PDF set for coordination issues, code compliance, and cross-discipline conflicts, catching anything that slipped through or emerged between disciplines.

How do the two platforms compare on security and compliance?

Both Helonic and Structured AI are SOC 2 compliant. Helonic is SOC 2 Type II certified, which is the standard most enterprise procurement teams require for handling sensitive design data.

Which platform is better for a general contractor?

Helonic. General contractors work with 2D PDF drawing sets, need Procore/Autodesk integration for RFI workflows, and want fast multi-discipline review without touching BIM software. Structured AI's Revit-centric approach and design engineering focus make it a poor fit for typical GC workflows.

Manas is the co-founder and CTO of Helonic, where he leads engineering and AI research for construction drawing analysis. He works directly with structural, MEP, civil, and fire protection engineers to translate the way they review drawings into AI systems that flag the issues that actually matter in the field. Before Helonic, he built machine learning pipelines for technical document understanding and has spent the last several years interviewing licensed design engineers and discipline leads to ground product decisions in real practice rather than industry assumptions.
