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.

GitHub features and specs

  • collaboration
    GitHub provides a platform for multiple developers to work on the same project concurrently, facilitating collaboration through features like pull requests, code reviews, and issues tracking.
  • integration
    GitHub integrates seamlessly with various third-party tools and services, such as CI/CD pipelines, project management tools, and many development environments, enhancing productivity and workflow efficiency.
  • version_control
    Utilizes Git for version control, allowing users to track changes, revert to previous versions if necessary, and manage different branches of development, ensuring code stability and history tracking.
  • community
    With millions of developers and a vast repository of open-source projects, GitHub fosters a robust community where users can contribute to projects, seek help, share knowledge, and collaborate broadly.
  • availability
    GitHub is a cloud-based platform, which means that projects are accessible from anywhere with an internet connection, providing flexibility and convenience to developers globally.
  • documentation
    GitHub allows for comprehensive project documentation through README files, wikis, and GitHub Pages, making it easier for users to understand project context and contribute effectively.

Possible disadvantages of GitHub

  • cost
    While GitHub offers free plans, more advanced features and private repositories come at a cost, which might be a barrier for some individuals or small teams.
  • steep_learning_curve
    For newcomers, especially those unfamiliar with Git, the learning curve can be quite steep, making it challenging to utilize all of GitHub's features effectively.
  • privacy_concerns
    Given its expansive, open nature, users must be cautious with sensitive or proprietary information. Even with private repositories, there is a latent concern over data privacy and security.
  • interface_complexity
    The user interface, while powerful, can be overwhelming and complex for beginners or those not deeply familiar with version control concepts.
  • performance_issues
    Occasionally, GitHub may experience downtime or performance issues, which can disrupt workflow and prevent access to repositories temporarily.
  • limited_storage
    GitHub imposes limitations on storage space and file size within repositories, which can be restrictive for projects requiring large datasets or binaries.

Questions & Answers

As answered by people managing GitHub 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.

The Top 10 GitHub Alternatives
However, like any (human) product, the platform has its limits, downsides, and critics.

Another criticism concerns the price tag: some users have pointed out that GitHubโ€™s pricing model is too inflexible. Moreover, some...
