Frequently asked questions
Does this tool upload my data?
No. The calculation runs locally in your browser.
Is this a replacement for specialist scientific software?
No. It is intended for quick calculations and screening; validate critical results with your established workflow.
Does a passing result guarantee a chemically valid molecule?
No. This is deliberately a lightweight syntax-level check and is not a valence or chemistry-engine validator.
