Accuracy & limitations
HyNote uses latest-generation AI to extract and condense PDF content. Results are most accurate for machine-readable, well-structured PDFs with clear text.
Accuracy may degrade on low-quality scans, heavily formatted tables, handwritten notes, or documents with complex multi-column layouts. OCR-processed documents may introduce character errors that affect summary quality.
Do not rely solely on AI-generated summaries for legal, financial, or medical decisions. Always verify critical claims, numbers, and obligations against the original source document.
For best results: upload native/digital PDFs rather than scanned images, ensure text is selectable in the original file, use higher-quality scans (300+ DPI) for scanned documents, and select the 'Key Takeaways' summary type for longer documents.
