Callout uses AI to perform first-pass construction drawing reviews against building codes and standards. Upload your PDF drawing sets, select from 33+ supported codes across 7 engineering disciplines (mechanical, structural, architectural, electrical, plumbing, energy, fire protection), and receive a structured list of findings in seconds.

Each finding includes a severity rating (Critical, Major, Minor, Advisory), confidence level (High, Medium, Low), exact code section citation, and a suggested resolution. Licensed PEs review each finding and accept, reject, or edit it. Over time, Callout learns from those decisions and adapts future reviews to match each engineer's judgment, without any model fine-tuning.

Key features:

-Multi-discipline single-pass review: check drawings against codes from all 7 disciplines in one run -Firm standards library: add plain-English firm-specific requirements that get checked alongside model codes -Jurisdiction amendments: upload local or state code amendments and cross-reference them against base codes -Confidence ratings: each finding signals how reliable the citation is, helping PEs triage efficiently -Export and sharing: CSV, Excel, and PDF export, plus read-only shareable report links for team collaboration -Organization support: shared credit pools, role-based access, firm-level calibration, and audit logging

Pay-per-use pricing with no subscription. Credits never expire. 50 free credits on signup, no credit card required. Built by a licensed Mechanical PE.

Questions & Answers

As answered by people managing GitLab and Callout.app.

What makes your product unique?

Callout.app's answer:

Callout learns from each engineer's decisions. When a PE accepts, rejects, or edits a finding, that feedback shapes future reviews to match their judgment. Over time, each engineer gets a personalized review profile without any model training. Combined with firm-specific standards, jurisdiction amendments, and multi-discipline single-pass review across 33+ codes, no other tool offers this combination.

Why should a person choose your product over its competitors?

Callout.app's answer:

Most tools in this space are either digital markup tools (Bluebeam, PlanGrid) that don't analyze drawings, or code lookup tools (UpCodes) that don't review uploaded plans. Callout is the only tool that takes a PDF drawing set, reviews it against building codes from all 7 engineering disciplines in one pass, and returns structured findings with exact code citations and severity ratings. It's also pay-per-use with no subscription, so you only pay when you use it.

How would you describe the primary audience of your product?

Callout.app's answer:

Licensed Professional Engineers and MEP firms who review construction drawings for code compliance. The typical user is a PE at a small to mid-size engineering firm who reviews mechanical, structural, electrical, plumbing, or fire protection drawings and wants a faster first pass before stamping.

What's the story behind your product?

Callout.app's answer:

Built by a licensed Mechanical PE who spent too many hours doing manual code compliance reviews. The idea was simple: AI is good at cross-referencing documents, and building code review is fundamentally a cross-referencing task. Callout started as a tool to speed up the founder's own review workflow and grew into a product for the broader engineering community.

Which are the primary technologies used for building your product?

Callout.app's answer:

Next.js, Anthropic Claude API, Supabase (PostgreSQL), Stripe, and Vercel.

Best GitHub Alternatives for Developers in 2023
While GitLab features an extensive set of capabilities, this can also serve as a weakness since beginners may find the developer tool overwhelming to begin with.
