Honest comparison
PerCode.ai vs Calcs.com (formerly ClearCalcs)
A strong browser-based structural platform with load linking — but no AI, structural-only, and your project data lives in their cloud.

Where PerCode is different
Their gaps: No AI. Structural only. Not for complex/high-rise; learning curve; perf on low bandwidth.
Table stakes we match
- Load linking / load-path propagation (treated as P0).
- Zero-friction trying — run a real calc in the browser in under a minute.
