Common Issues
Summary missing important points?
Try 'Detailed' summary mode for more comprehensive coverage. The AI prioritizes the most frequently mentioned and contextually important information.
Processing taking too long?
Very long documents are processed in segments. Wait for the progress indicator to complete. For extremely large files, consider splitting the document first.
