Why does SciSpace work better with text-based PDFs?+
SciSpace's AI reads the text layer of the PDF. Scanned documents stored as images require OCR processing before the text can be extracted and analysed.Source: SciSpace ↗
What should I do if my PDF is too large for SciSpace?+
Compress the PDF below 100MB using the tool above. For very long monographs or books, split by chapter and upload each section separately for better analysis accuracy.Source: SciSpace ↗
Why is my scanned PDF not working in SciSpace?+
Scanned PDFs are stored as images rather than text. SciSpace may require OCR processing to extract text from them. Run OCR on the document first, then re-upload.Source: SciSpace ↗
Does compressing a PDF affect SciSpace's research analysis?+
No. SciSpace reads the text layer of the PDF. Compressing image quality reduces file size without affecting the text content used for AI analysis and citation extraction.Source: SciSpace ↗
