- Integration relies on a proprietary entitlement check API that verifies user ownership of the digital asset before allowing the document to be indexed in the notebook's vector database.
- The 'Audio Overview' feature utilizes text-to-speech synthesis models that process the extracted book content to generate conversational, multi-speaker audio summaries.
- The system supports inline citation mapping, which links model output tokens back to specific page offsets and paragraph indices within the source e-book file.
