How AI Summarizer works
When you open a PDF in your browser, the tool extracts the text and sends only that text to an AI model for summarisation. If the AI service is unavailable, the browser creates a key-sentence summary locally. Long documents are broken into sections, each summarised, then combined into a final output. The original file never leaves your device.

Questions
AI Summarizer: common questions
Is AI Summarizer free?
Yes, the tool is completely free to use. There are no hidden charges, subscriptions or fees for any of its features.
Are my files safe when I use AI Summarizer?
Your PDF is opened only in your browser. Only the extracted text is sent to the AI model; the file itself is never uploaded or stored on our servers.
Does AI Summarizer work on a phone?
Yes, it works in any modern mobile browser. You can open a PDF, summarise it and view the results directly on your phone.
What file formats can I summarise?
The tool accepts standard PDF files. It extracts the text from the PDF and then creates the summary, so any PDF that can be opened in a browser is supported.
Is there a limit to how much text can be summarised?
There is an hourly usage limit per visitor to protect the AI service, and very large files depend on your device’s memory. If a file exceeds those limits, you may need to split it into smaller sections.
