Support

Ingest Air is a small app made by one person. If something isn't working, email me and I'll actually read it.

It helps to include your device and OS version, the file format you were opening (PDF, EPUB or MOBI), and what you saw on screen.

Common questions

The app says Apple Intelligence isn't available

Ingest Air uses Apple's on-device model, so it needs a device that supports Apple Intelligence with the feature switched on. Check:

Device: iPhone 15 Pro or later, an iPad with A17 Pro or M-series, or a Mac with Apple silicon.
OS: iOS/iPadOS 26 or later, or macOS 26 or later.
Setting: Settings → Apple Intelligence & Siri, and make sure it is on.
Language: your device language must be one Apple Intelligence supports.
Download: the first time you enable it, the system downloads the model. That can take a while, and Ingest Air will say the model isn't ready yet until it finishes.

Summarizing a long book is taking a while

Ingest Air reads the entire book rather than skimming it, so a long book takes several minutes. Progress is shown section by section so you can see it moving.

You can leave the screen, and finished sections are saved as it goes — if you quit part way through, reopening the document resumes rather than starting again.

A PDF failed with "no text" or asked to run text recognition

Some PDFs are images of pages rather than text — typically scans. Ingest Air will offer to run text recognition on the document, which happens on your device. It is slower than reading a normal PDF, roughly a second a page.

If recognition still finds nothing, the scan may be too low-contrast or too low resolution to read.

A book failed to summarize

Try the Try Again button first. Any sections already finished are reused, so a retry is usually quick.

Apple Intelligence occasionally declines to process particular passages. If a specific book fails repeatedly, please email me the title — that's genuinely useful and I can often fix it.

Can I use a different, larger model?

Not in Ingest Air — it uses Apple's on-device model only, which is what lets it ship with no network access and no downloads.

Its sibling app, Ingest for Mac, runs larger open-weight models locally instead. It is heavier and slower, but stronger on long or difficult books.

How do I delete a document?

On iPhone and iPad, swipe left on it in the library. On Mac, right-click it and choose Delete, or select it and press the Delete key. If several failed, the trash button in the toolbar clears all of them at once.

This removes the app's stored summary and text. Your original file is never touched.

Where is my data stored, and is any of it uploaded?

Everything stays in the app's private storage on your device. Nothing is uploaded — Ingest Air ships without the network entitlement, so the operating system will not allow it to make any network request at all. See the privacy policy for the full detail.

Which file formats are supported?

PDF, EPUB, and MOBI. Some newer Kindle files (KFX, and DRM-protected purchases) cannot be opened by any third-party app and are not supported.

Reporting a bug

Email support@ingestair.space with what you did, what you expected, and what happened instead. If it involves a specific document, the title and format help a great deal. Please don't send the file itself unless I ask — you own it, and I'd rather not have a copy.
