Can Apple Intelligence summarize documents?
Yes. On a supported iPhone, iPad, or Mac, Apple Intelligence can read a document and write a summary on-device, so the file stays on your device. Inscribe uses this to summarize PDFs, Word files, spreadsheets, and long recordings locally, with a downloadable offline model as a fallback when Apple Intelligence is not available on your device.
What "on-device" actually means here
The summary is produced by a model running on your own hardware. Your document is not uploaded to a server for processing, and there is no account to create. In Inscribe, recording, transcription, summaries, and document Q&A run on-device, so the text you feed in and the summary you get back do not pass through a cloud AI provider.
Two honest caveats: optional iCloud sync exists and is off by default, and the app records anonymous usage analytics with no account attached. The part that matters for a sensitive document is the part that stays local: the reading and summarizing itself.
Which files can it summarize?
- PDF reports, papers, and contracts
- Word, Excel, and PowerPoint files
- Plain text and pasted notes
- Images, where on-device OCR reads the text first
- Recordings, which are transcribed on-device and then summarized
Apple Intelligence vs a cloud summarizer
| What happens to your file | Cloud summarizer | Inscribe (Apple Intelligence + offline model) |
|---|---|---|
| Where the summary is generated | On a remote server | On your device |
| File uploaded for processing | Yes | No |
| Account required | Usually | No |
| Works with no internet | No | Yes |
| PDF, Office, images, recordings | Varies | All of them |
How the offline fallback works
Apple Intelligence needs a recent device and a supported language. When it is not available, Inscribe can use a small model you download once (Qwen 3, about 400MB) that runs entirely offline. You choose a model or let Auto pick the best one available. Either path keeps the work on-device, so a document you would never paste into a website can still be summarized on a plane or with Wi-Fi off.
Summary styles you can pick
A single long file rarely needs a single kind of summary. Inscribe can produce a few different shapes from the same document:
- Concise, a short paragraph that captures the gist
- Bullets, the main points as a scannable list
- Structured, headings with grouped detail
- Action items, the decisions and to-dos pulled out
- Outline, the document's skeleton for study or review
Because the summary sits next to the original text, you can read the short version first and jump into the full document only where you need to.
Beyond the summary: ask it questions
A summary answers "what does this say?" Sometimes you need "what does it say about clause 7?" instead. After a file is imported, you can chat with it on-device: ask a question, get an answer grounded in the document, and follow up. Ask Inscribe can also search across your whole library, so a question can pull from several files at once, all locally.
How to summarize a document with Apple Intelligence
Open Inscribe, bring in the file you want to shorten, and let it summarize on-device. You choose the summary style, and if your device does not support Apple Intelligence, the downloadable offline model handles it instead. The steps below walk through it, and the finished summary exports to PDF or text with the original attached.
A note on languages
Summaries work across the 15 languages Inscribe supports, including English, Spanish, French, German, Italian, Portuguese, and Japanese. This is summarizing text in the language it is already written in. There is no translation feature, so a French document is summarized in French, not turned into English.

Frequently Asked Questions
Does Apple Intelligence summarize PDFs offline?
Yes. On a supported device the summary is generated on-device, so a PDF can be summarized with no internet. When Apple Intelligence is unavailable, Inscribe uses a downloadable offline model that also runs locally.
Is my document uploaded when it gets summarized?
No. The reading and summarizing happen on your device. The file is not sent to a cloud AI provider for processing, and no account is required to use it.
Which file types can be summarized?
PDF, Word, Excel, PowerPoint, plain text, images (via on-device OCR), and recordings, which are transcribed first and then summarized. All processing stays on-device.
What if my iPhone does not support Apple Intelligence?
Inscribe falls back to a small offline model you download once, about 400MB. It generates the summary locally, so you still get on-device summaries without a supported Apple Intelligence device.
