Callout uses AI to review construction drawing PDFs against 33+ building codes across 7 engineering disciplines. Upload your drawings, select applicable codes, and get structured findings with exact code citations, severity ratings, and suggested resolutions in under 60 seconds. Built for licensed Professional Engineers and Architects.

MeltPlan is the AI-native planning engine for the built environment, bringing code compliance, cost, schedule, and value engineering into one connected system. It helps architects, engineers, and contractors make faster, more confident decisions before construction begins — with transparent reasoning, verifiable sources, and workflows built for real project execution.

Melt Takeoff by MeltPlan is an AI-assisted takeoff service for construction estimators that combines AI speed with expert estimator verification. It delivers accurate quantities plus detailed allowances for scope not shown on drawings, with interactive outputs and clean Excel exports—helping contractors bid faster with confidence.

AI that generates construction blueprints

A subject-level checker for drawing sets that compares a submittal against a prototype (a reference set encoding the organization's brand or design standards).This collapses what is normally a slow, inconsistent manual review into a list of pre-located, pre-justified deviations, so reviewers spend their time accepting or rejecting findings instead of hunting for them.

Compares your review comment log against a submittal PDF and automatically classifies each comment with customizable verdicts such as resolved, not resolved, or investigate. Each comment is matched to the exact location on the drawing and flagged with a bounding box highlight, giving reviewers a direct path to the evidence without manually cross-referencing spreadsheets and drawings.
