While our algorithms do a good job distilling the majority of documents into their key facts and findings, sometimes they struggle! If you find that a particular document does not upload, try one of the following:

• If the document is a scanned PDF image, run it through OCR software first. There are both free and commercial software available for this.
• If the document is a complete book, try breaking it down into separate chapters, and upload one chapter at a time
• If the document is very large or many pages long, try breaking it down into smaller files and upload each of these separately
• If the document contains many figures and images, try switching off Extract Figures in Settings > Import.
• Send us the PDF and we’ll investigate
