Built-in Tools

The Agent can automatically look up site-specific seismic parameters from USGS maps in real-time during your calculation workflow.Example: “Get the seismic parameters for 123 Main Street, Seattle, WA and design per ASCE 7-22”
Retrieve site-specific wind speed data automatically based on location and building parameters.Example: “Determine the basic wind speed for a Risk Category III building in Miami, FL”
The Agent observes patterns in your prompts and deliverable structure to refine its output over time. It learns your preferred formatting, variable naming conventions, and typical calculation presentation order.
Privacy Note: Your style profile is unique to your account and is not shared or used for global model updates.
What the Agent Learns:
  • Your preferred formatting for calculation headings
  • Common variable names you use
  • Typical order you present checks in Mathcad sheets
  • Your firm’s calculation structure and organization
  • Preferred level of detail in code references
Example: If you consistently use f_c instead of fc for concrete strength, or prefer to show “Design Summary” sections at the top of calculations, the Agent will adapt to match your style over time.

Included Modules

Mathcad Module

Supports Mathcad Prime 9+ onlyGenerate, edit, validate, and QC Mathcad calculation sheets with full code traceability and unit safety.
Capabilities:
  • Create new calculation sheets from scratch
  • Edit existing Mathcad files
  • Validate calculations against building codes
  • Perform QC checks on deliverables
  • Migrate hand calculations to digital format
  • Generate professional PDF outputs
What You Get: All generated .mcdx files are fully editable in Mathcad Prime. You can modify inputs, add checks, or adjust formatting as needed.

Frequently Asked Questions

Stru AI supports Mathcad Prime 9 and later versions. Earlier versions are not compatible.
Yes! Upload your templates to your Private Knowledge Base, and the Agent can use them as starting points for new calculations.
Simple calculations: 30-60 secondsComplex calculations with multiple checks: 2-5 minutesTime varies based on complexity and number of Agent tool calls.
Absolutely! All generated .mcdx files are fully editable in Mathcad Prime. You can modify inputs, add checks, or adjust formatting as needed.
Always review Agent output with professional engineering judgment. If you find an error:
  1. Report it to us at bhosh@stru.ai
  2. Provide feedback in your next prompt to correct the approach
  3. The Agent will learn from the correction
Remember: The Engineer of Record is responsible for all deliverables.
Yes! Your request quota is shared across your entire team (as many seats as needed). See the Pricing page for details.
Currently, Stru AI focuses on US codes (ACI, AISC, ASCE, IBC, etc.). International code support is planned for future releases. Contact us to discuss your specific needs.
During Beta:
  • Stricter guardrails maintain quality
  • Some advanced features have usage limits
  • We actively incorporate user feedback
  • Pricing for certain module features may be waived
You’ll be notified before any changes to features or pricing.
