AI-Assisted Plan Review for AHJs and Third-Party Reviewers
Helonic is an AI construction drawing analysis platform for Plan Reviewers doing Pre-Permit Review.
Apply the same code rigor to every submittal regardless of reviewer workload.
What is pre-permit review for plan reviewers?
Pre-permit review for plan reviewers is the code-compliance and completeness check they apply to a permit submittal before a building department issues approval. AI-assisted review helps reviewers maintain consistent depth across the submittal volume by handling the dimensional and citation-based checks that pattern-match well, leaving reviewer attention for the judgment-heavy items.
Why do plan reviewers struggle to keep review depth consistent?
Plan reviewers have to enforce code the same way on every submittal, but workload and volume often force them to skip items. Some reviewers see every detail; others see only the headline items. AI-assisted review provides a baseline of consistent depth so every submittal gets the same systematic check.

Can this replace plan reviewers?
Helonic augments plan reviewers rather than replacing them. Code interpretation, professional judgment, and negotiation with applicants still require human reviewers.
Does this work for jurisdictions with local amendments?
Helonic supports custom rule packs for jurisdiction-specific amendments.
Is the audit trail admissible for appeals?
Helonic produces a structured record of checks performed. Whether it's admissible in appeals depends on jurisdiction policy.
