AI Summarizer
AI Summarizer extracts the text of a PDF (up to the first ten pages) and asks your configured AI model for a structured summary with key points. It is designed for long reports where you need the substance before reading the whole document.
How to use AI Summarizer
- Connect your own API key in the AI panel at the top of the tool.
- Upload the PDF you want summarised.
- Run the tool and read the generated summary in the output panel, then copy it if you need it elsewhere.
Where AI Summarizer is useful
- Getting the gist of a 40-page industry report quickly.
- Preparing talking points from a research paper before a meeting.
- Triaging a long document to decide whether a full read is needed.
Formats, algorithms and limits
Text is extracted locally with PDF.js and only the extracted text — never the file itself — is sent to the AI provider you configured. The extraction covers the first ten pages, and the request is capped in length, so very long documents are summarised from their opening sections.
Troubleshooting and honest limits
- Scanned PDFs have no text layer and produce an empty summary; extract or OCR the text first.
- Treat the summary as a reading aid, not a source: verify any figure or quote against the document itself.
- For documents longer than ten pages, split the file and summarise the sections you care about.
Frequently asked questions
Is my document uploaded to a server?
The PDF stays in your browser and is parsed locally. Only the extracted text of the first ten pages is sent to the AI model you connected, using your own API key.
Why is the summary empty?
The file is most likely a scan without a text layer. Extract the text first, or use a document that was exported digitally.
How much of a long document is covered?
The first ten pages of extracted text. For a large report, split it into sections and summarise each part separately for fuller coverage.
Do I need an account on this site?
