Both read PDFs without a BIM model. Helonic is a drawing review product. MeltPlan is a set of estimating and precon tools, one of which reviews documents.
MeltPlan rows come from meltplan.com as of October 2026.

"Not listed" and "no certification named" mean MeltPlan's public pages don't describe the item. They are not a confirmed absence. Confirm with the vendor for your evaluation.

MeltPlan calls itself an AI-first preconstruction platform for general contractors. According to meltplan.com, the platform covers the work from concept to GMP through separate products: Melt Bid, Melt Review, Melt Takeoff, and Melt Code, with Melt Schedule also mentioned.
MeltPlan publishes its own accuracy figure of 95% or better on preconstruction tasks. That's a vendor number; ask how it was measured and test it on a job you've already bid.
Melt Review is built around GC precon deliverables. The Melt Review page describes three outputs: design acceptance criteria checks against AIA phase-appropriate criteria, a sheet-by-sheet design change narrative between issuances, and precon reports listing sole-source items, mockups, and testing requirements. Findings export as a BCF file for the design team.
Helonic is built around the findings list. Every review returns issues in ten categories, from coordination and code compliance to fire safety, accessibility, and dimensions. Each finding carries a high, medium, or low severity and the page coordinates of the spot on the sheet. Helonic has completed more than 1,000 reviews across more than 1,000,000 pages and flagged more than 2,000,000 issues.
If your estimators need the sole-source list before buyout, Melt Review does work Helonic doesn't. If your project team needs a duct-through-beam conflict on M-201 tracked to an RFI, that's Helonic's job. The guide to reviewing construction drawings lays out which checks belong in each pass.
They approach code from opposite ends. Helonic checks the drawings against the model codes IBC, NEC, NFPA, and ADA Standards and against state and local adopted codes such as the CBC, inside the same review as coordination, and each finding names the sheet and code section. See Helonic's code compliance checks.
Melt Code is a research assistant. You ask a code question and get cited requirements and decision trees for your project, and MeltPlan says it reasons across local amendments. Its page describes research, decision trees, and reusable checklists rather than a scan of your drawing set.
In Helonic, a reviewer accepts or edits each finding before anything is created in Procore or Autodesk Construction Cloud. The approved finding becomes an RFI with the sheet reference attached, through the Procore integration or the Autodesk integration.
MeltPlan sends Melt Review findings to the design team as BCF files. Its homepage lists integrations with Google Workspace, Microsoft 365, SharePoint, Box, and BuildingConnected. Procore isn't on that list, so ask MeltPlan how findings reach your RFI log if that's where your team works.
MeltPlan prices on square footage. Its pricing page describes usage-based billing on the square footage you run through the platform, unlimited seats and projects, and lower rates at higher volume. Quotes are custom. Helonic pricing is also custom, based on project volume and team size.
MeltPlan says customer data is encrypted at rest and in transit, isolated per organization, and never used to train its models. Its public pages, including its security disclosure policy, don't name a certification. Helonic is SOC 2 compliant, with TLS 1.2 or higher in transit and AES-256 at rest; details are on the security page.
Run both on a set you've already reviewed by hand. Give each tool the same PDFs, then count findings a reviewer confirms on the sheet, false alarms, and whether each location lands on the problem.

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: MeltPlan details come from meltplan.com, including the Melt Review, Melt Code, pricing, and security disclosure pages, read in October 2026. Helonic facts come from the Helonic press facts page. Rows where MeltPlan's public pages say nothing are marked that way rather than assumed absent.
