Frequently Asked Questions About Rationale Generation

Answers to common inquiries regarding content input and output formats for our AI diagnostic tool.

How does the AI ensure the rationales provided for all options are accurate?

The AI analyzes the semantic context of the source material you upload, cross-referencing the correct answer's derivation and the logical fallacy or incorrect premise associated with each distractor option to build relevant explanations.
