It's ideal for marketing consultants who need to fact-check client reports, content researchers verifying sources, product managers planning new features, master's students structuring literature reviews, and PhD candidates finding citations.
Real use cases

In professional settings, it turns scattered thoughts into clear documents like business proposals, internal reports, and weekly newsletters.
