The basics
Get a corpus
CorpusKit Reader comes with a few sample corpora built in. For more, Browse Catalog for free corpora to download, Import a .corpus from Files or iCloud Drive, or make your own with CorpusKit Studio.
Open one
Tap a corpus in your library to load it. Loading happens once, on your device.
Ask a question
In Chat, type a question in plain language. The Reader finds the passages that actually answer it — by meaning, not just keywords. On devices with Apple Intelligence, it also writes a short answer grounded only in those passages. Every answer shows its sources so you can check them.
Read in context
Switch to Read to browse the source by chapter, or tap through from any answer to the exact passage in the text.
Save what you find
Bookmark passages to keep them in Saved, and jump back to any of them in the text with Read in Context.
Good to know
- Everything runs on your device. Your questions and what you read never leave it — search and answers work fully offline.
- The catalog opens in your browser; you download a
.corpuswith your own tools, then open it in the Reader. There's no account and no tracking. - Grounded, on-device answers require a device that supports Apple Intelligence. On other devices you still get the most relevant passages, ranked.
