How to summarize a PDF with AI
Summarize with AI reads the text of your document and writes a summary with its main ideas, relevant figures and the limitations it mentions, in no more than 800 words. You download it as a PDF, ready to read, share or file alongside the original.
It is handy for getting the gist of a report, an article, a call for applications or a contract before reading it in detail. It is a Naiara Plus feature: anyone can see the tool, but you need to be signed in with an active subscription to use it.
Step by step
- Sign in with your Naiara Plus account.
- Upload the PDF you want to summarize.
- Choose the summary language: English, Spanish, French, German, Italian or Portuguese.
- Process and download the summary PDF.
Document limits and requirements
The AI handles up to 10 pages and 40,000 characters of text per document. If your PDF is longer, pull out the part you need with Extract pages or Split PDF and summarize each block.
The PDF must contain selectable text. A scan is an image with nothing to read, so run it through OCR PDF first. The summary language can differ from the document's, which also makes it useful for understanding a text written in another language.
Privacy and reliability
To generate the summary, the text extracted from the PDF is sent to the AI provider; the tool tells you so before you use it. If the document contains especially sensitive data, consider redacting it first with Redact PDF and applying OCR to the result.
An automatic summary can miss nuance or misread a sentence. Use it as a reading guide and check any figure, deadline or condition against the original before making a decision.
