About
Callout is an AI-powered SaaS that performs first-pass construction drawing reviews against building codes. Professional Engineers and Architects upload PDF drawing sets, select from 33+ supported codes (IMC, IBC, ASHRAE, NFPA, NEC, IPC, ASCE, ACI, AISC, and more), and receive structured findings with severity ratings, exact code section citations, and suggested resolutions in under 60 seconds.
Key features: multi-discipline review across 7 engineering disciplines in a single pass, PE calibration that adapts to each engineer's judgment over time, firm standards library for custom requirements, jurisdiction amendment uploads for local code checking, confidence ratings on every finding, and full review history with CSV, Excel, and PDF export.
Credit-based pricing starting at $0.13 per sheet. No subscriptions, no seat licenses. 50 free credits on signup. Built by a licensed Mechanical PE.

About
Piper is the AI operating system for preconstruction, built for general contractors' pursuit and estimating teams.
Piper connects drawings, specifications, addenda, quotes, estimates and company knowledge so teams can generate scopes, level bids and review risk — with every finding linked back to the drawing, spec clause or addendum it came from.
Scope Generation: turn drawings, specifications, addenda and company standards into source-backed trade scopes, so you know exactly what you are asking each trade to carry.
Bid Leveling: compare subcontractor bids against the intended scope, so the low number does not hide an expensive gap.
Final Bid Review: review the estimate against the project behind it, and focus senior attention on what still deserves judgment.
Survey: turn your company's experience into a repeatable survey that captures what the team learns on every project.
Piper is not a takeoff or estimating calculator, and it does not replace estimator judgment.
