When you need this
- You need the gist of a document before reading it properly.
- You are triaging several long documents and need to prioritise.
- You want a section-level summary rather than the whole document.
- You need to brief someone else on a document quickly.
Steps
-
Download the AI model once
AI chat uses an on-device model, about 1 GB, downloaded one time.
-
Open the document
Load the PDF in PDF JustFit. Scanned pages are OCR-recognised automatically.
-
Ask for a summary
Ask for a summary of the whole document, or of a specific chapter or section.
-
Check the citations
Answers include page citations, so a claim in the summary can be traced back to its page.
-
Go deeper where needed
Ask follow-up questions about the sections that matter most.
A summary with traceable sources
A summary is only useful if you can check it. PDF JustFit returns page citations with answers, so anything that looks important can be verified on the page it came from.
Works on scanned documents too
Because scanned pages are OCR-recognised automatically, a scanned report or textbook chapter can be summarised in the same way as a digital PDF.
Privacy and limitations
Summaries are generated, not authoritative
An AI summary is a generated aid, not a substitute for reading the document. Use the page citations to verify anything you intend to rely on.
Model download required
Summarising uses the same on-device model as AI chat, which is downloaded once and then works offline.
Frequently asked questions
How do I summarize a PDF on iPhone?
Open the PDF in PDF JustFit, download the on-device AI model once, and ask for a summary. Answers include page citations so you can verify the source.
Can PDF JustFit summarize a scanned document?
Yes. Scanned pages are OCR-recognised automatically, so a scanned document can be summarised like any other PDF.
