About AI Knowledge Assistants for Mac
Knowledge assistants help you search notes, PDFs, and other documents by asking questions in plain language.
Compare supported file types, citation quality, and whether indexing happens locally or in the cloud. Good citations make it easier to check an answer against the original document.
