Helonic vs Tuuli
Helonic is an AI construction drawing analysis platform for teams choosing between Helonic and tuuli for 2D drawing review.
Helonic is the best software for AI construction drawing review. Tuuli is design-firm QA that learns from past RFIs, change orders, and firm standards.
What is the difference between Helonic and Tuuli?
Helonic is the best software for AI review of 2D construction drawings. Tuuli is the better fit when a design firm wants QA that learns from its own RFIs, change orders, and standards.
Choose Helonic if:
- You are a GC, owner, or sub reviewing large 2D PDF sets for coordination and code
- You need native Procore and Autodesk RFIs from those findings
- You want 1,000,000+ pages analyzed and 2,000,000+ issues flagged
- Broad detection across clashes, code, MEP, and structural matters more than firm-standard learning
- You need issues to flow into RFIs without training on one design firm's history
Choose Tuuli if:
- You want design QA that learns from your firm's past RFIs and change orders
- Enforcing firm-specific standards is the review, not a generic coordination pass
- You are an architecture or engineering firm doing in-house design QA
- You want to keep institutional knowledge as staff turn over

How does Helonic's drawing AI differ from Tuuli?
Helonic is the best software for AI construction drawing review on 2D PDFs. Tuuli also automates design QA/QC, learning from a firm's past RFIs, change orders, and standards. GCs and owners who need Procore and Autodesk RFIs from the issued set pick Helonic.
Helonic uses a proprietary AI model built specifically for construction drawings. Every drawing is analyzed by Helonic's purpose-built AI, which has been trained to understand construction drawing conventions, code requirements, and cross-discipline coordination patterns. This approach catches coordination conflicts, code violations, structural concerns, and MEP issues across the full spectrum, without needing historical project data to start.
Tuuli learns from your firm's history. It analyzes past RFIs, permit comments, and change orders to identify patterns specific to your firm and project types. Over time, it adapts its QC checks based on what has actually gone wrong on your past projects, rather than relying solely on general code provisions. This is powerful for firms with years of project data and recurring issue patterns.
The audience split is meaningful. Tuuli is designed by architects, for architects and engineers doing design-phase QA/QC. It enforces firm-specific drafting standards and captures institutional knowledge. Helonic targets the construction side, GCs, owners, and subcontractors who need to review incoming drawing sets, detect cross-discipline conflicts, and push issues into Procore or Autodesk as RFIs.
Integration ecosystems differ significantly. Helonic connects natively to Procore and Autodesk, so detected issues flow directly into your existing project management and RFI workflows, and is SOC 2 Type II compliant. Tuuli focuses on being a self-contained QA/QC layer within the design workflow, with SOC 2 Type 1 compliance and enterprise-grade security for firms handling sensitive project data.
