About AI Summarizer

Long contracts, dense research papers, hundred-page board reports — AI Summarizer reads the whole thing and gives you the key points in the length you choose. Perfect for triage, study, or quick stakeholder briefings.

Pick from very short (100 words, two paragraphs) up to detailed (1500 words, executive briefing). We extract the text from your PDF (scanned PDFs need OCR first), pass it to a leading LLM, and stream back a clean summary as a .txt file.

AI Summarizer — frequently asked questions

Everything you need to know.

Which AI model do you use?

We use a leading frontier LLM. For privacy-sensitive Business customers we offer self-hosted models — ping us if you need that option.

Will the summary be accurate?

Yes for documents that have clear, well-structured prose. Heavily tabular or numeric documents (financial reports, scientific datasets) benefit from a specific prompt — contact us for the Business AI API.

Do you use my PDF to train AI?

Never. Uploads are processed in isolated workers, used only to produce the summary, and deleted within 60 minutes. We never train AI on customer documents.

How long can the input PDF be?

Up to your plan's max page count (100 free / 2000 Pro / 5000 Business). Very long PDFs are chunked and stitched.

Can I summarise in a different language?

Yes — the summary will be produced in the same language as the source PDF, or specify a target language via the Advanced JSON.
