Delegate

Hand off the calc.

Give AI engineering tasks using the web app, sending an email, or from Claude on your desktop/phone. The AI model can use clearspan's tested engineering tools, the same ones you would use yourself. The AI does not need to do its own math.

Privacy

Your projects stay yours.

Project redaction strips client names and project identity before anything reaches the model. The AI sees a beam, not your business.
