Premise & Conclusion Identifier

Paste a passage, name the conclusion, list the premises. The tool flags conclusion- and premise-indicator words it sees in the passage and runs structural sanity checks (no circularity, conclusion not invented from thin air). It does not grade whether the premises actually support the conclusion — that judgment is yours.

Used in: Foundations of Logical Reasoning (especially “Arguments and Their Parts”). The full lesson walks through what counts as a premise vs. a conclusion, with worked examples.
