Frequently Asked Questions
How does Cluster AI preserve citations and formulas during humanization?
Before rewriting, the Factual & Citation Preservation Agent identifies and tokenizes all LaTeX math, numbers, dates, URLs, and academic citations (e.g., '[Smith et al., 2024]') into immutable tokens that cannot be modified.
