Comprehensive AI drawing set analysis versus automated submittal review and RFI processing. Two tools targeting different stages of the construction document workflow.

Quick summary

Choose Helonic if:

You need full drawing set analysis across all disciplines
Proprietary AI analysis is important for detection accuracy

Drawing sets vs documents

Helonic and Ichi Automation apply AI to construction documents in fundamentally different ways. The distinction comes down to scope: Helonic analyzes entire drawing sets holistically, while Ichi processes individual documents like submittals and RFIs.

Ichi Automation excels at automating the submittal review and RFI response workflow. When a submittal comes in, Ichi compares it page-by-page against the relevant specs and codes, flagging non-compliant items in 10–15 minutes. For RFIs, it pulls from project history and code references to draft responses in 10–20 minutes. This is a focused, high-throughput automation tool designed for architects and jurisdictions who process large volumes of individual construction documents.

Helonic takes a whole-set approach, analyzing drawings across all disciplines simultaneously. Rather than processing one document at a time, Helonic looks at the relationships between architectural, structural, mechanical, electrical, and plumbing sheets to detect cross-discipline clashes, coordination gaps, and code violations that only become visible when drawings are reviewed together. Helonic's proprietary AI was purpose-built for construction drawings, reducing false positives through deep domain expertise.

Both tools have Procore integration, but they use it differently. Ichi pulls submittals and RFIs from Procore for processing. Helonic pushes analysis results and generated RFIs into Procore, and also connects to Autodesk for drawing sync. For GCs and owners who need to verify the quality of an entire drawing set, Helonic provides the broader analysis. For architects and reviewers drowning in submittals, Ichi offers targeted automation.

Frequently Asked Questions

What's the difference between drawing review and submittal review?

Drawing review (Helonic) analyzes the construction drawing set itself, floor plans, sections, details, schedules, looking for coordination issues, code violations, and missing information across disciplines. Submittal review (Ichi) checks that products and materials submitted by contractors comply with the project specifications and applicable codes. They're sequential steps: drawings define what to build, submittals verify the products used to build it.

Can Helonic and Ichi Automation be used together on the same project?

Yes, and they complement each other well. Use Helonic early to analyze the drawing set for issues before construction begins, then use Ichi to automate submittal reviews and RFI responses as the project progresses. The tools cover different phases and document types with minimal overlap.

How do their Procore integrations differ?

Ichi pulls submittals and RFIs from Procore to process them through its AI review engine. Helonic pushes analysis results into Procore, including generated RFIs from detected issues. Helonic also integrates with Autodesk for drawing management, while Ichi focuses exclusively on the Procore ecosystem.

Which tool is better for general contractors versus architects?

Helonic is designed for GCs, owners, and subcontractors who need to verify the overall quality and coordination of a drawing set. Ichi targets architects, engineers, and jurisdictions who need to process high volumes of submittals and RFIs efficiently. The right choice depends on your role and which document workflow bottleneck you're trying to solve.

How fast are results from each platform?

Ichi is optimized for speed on individual documents, 10 to 15 minutes for submittal reviews, 10 to 20 minutes for RFI analysis. Helonic's analysis time depends on drawing set size since it processes all sheets and cross-references across disciplines, but results are typically available within minutes of upload for standard drawing sets.

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.
