Summarizer AI

Summarizer AI, also called Document Summarizer AI, is an iPhone and iPad app that uses AI to summarize PDFs, web articles, pasted text and scanned paper documents. It produces summaries in seconds in the length, format and language the user chooses. The app is aimed at students, professionals and researchers, and at anyone with a long reading list who wants the main points of a text without reading all of it.

There are four ways to add material: paste an article URL, paste text such as notes, emails or essays, upload a PDF, TXT or RTF file, or scan paper pages with the camera, where built-in OCR reads the printed words. The user then picks a length, from 2–3 sentences to one paragraph or a detailed summary, and a format: flowing paragraph, bullet points, key takeaways or action items.

Summaries come back in the document's own language, with 30 languages supported, from Japanese to Hindi, including English, Spanish, French, German, Italian, Turkish and Arabic. Recent summaries are saved on the device for quick access, and on supported iPhones Summarizer AI uses on-device Apple Intelligence. The developer, Deniz Cagilligecit, states that no data is collected from the app, and no account or sign-up is needed to use it.

Summarizer AI includes a number of free summaries every day. Summarizer Pro adds unlimited daily summaries, full-length documents, PDFs and scans up to 4× longer, the key takeaways and action items formats, and the developer's most advanced AI model. Pro costs $6.99 a week or $29.99 a year, or $79.99 as a one-time lifetime purchase. The app requires iOS 15.0 or later and also runs on Macs with an Apple M1 chip or later.
