## What is PDF Dictionary?

Keep unfamiliar words close to the page where you found them. PDF Dictionary brings reading, lookup and learning into one place.

READ FOR FREE
Import and read PDFs, use the system dictionary, get basic word or sentence translations, and copy text or translations. Tap words on iPhone and iPad, or use a pointer on iPad and Mac. Read supported web pages, save pages as PDFs, and download PDF links directly to the app’s Downloads folder.

LEARN WITH PRO
Save expressions with their context in vocabulary notebooks. Use a notebook for each PDF or choose your own folder; each PDF remembers its destination. Practice meaning and spelling quizzes. Add underlines, highlights and pen notes. Pro also removes banner and app-open ads on iPhone and iPad.

Web AI needs internet and your own ChatGPT or Claude account. External subscriptions and usage limits are separate from Pro. ChatGPT requires your permission before the app sends selected text and nearby sentence context; optional auto-send can send later selections. Turn ChatGPT text sharing off in the Web AI menu. For Claude, use Copy Prompt, paste the prompt into the chat and send it yourself. The app does not automatically insert or send text to Claude. The provider’s privacy policy applies.

BEFORE YOU READ
Basic translation may require language-model downloads. Availability varies by device and language pair. Download supported models before offline translation. Lookup accuracy and support depend on document text quality. Scanned or protected PDFs and web pages may have limits.

Pro offers yearly and monthly subscriptions that renew automatically until canceled. Manage or cancel in your App Store account.
