About this app

Summary AI helps you turn long text, PDFs, documents, articles, books, photos, scanned pages, and YouTube links into clear TLDR summaries, quick summaries, study notes, quizzes, flashcards, key points, outlines, and notes.

Use Summary AI as a TLDL, TLDW, TLDV, TLDR, TL;DL, TL;DW, TL;DV or TL;DR app to understand long content faster without reading, watching, viewing, or listening to everything.

Create an AI summary, PDF summary, photo summary, YouTube summary, scan summary, document summary, article summary, book summary, synopsis, outline, quick summary, or study notes from your own content.

Summarize many types of content:
• PDF summary for reports, papers, ebooks, and study files
• Document summary for DOCX, PPTX, EPUB, ODT, and TXT files
• Article summarizer for web pages, blogs, and long online articles
• YouTube summary from video links
• Book summary for popular books and written material
• Photo summary from scanned pages, printed text, notes, and documents
• Scan summary from camera photos, pages, worksheets, and paper notes
• Text summarizer for typed or pasted text

Type directly, paste text, import files, open links, share content from other apps, or take a photo with your camera. Summary AI extracts the content and turns it into structured results automatically.

Choose the format that fits your goal:
• TLDR summary
• TLDL summary
• TLDW summary
• TLDV summary
• Extract summary
• Quick summaries
• Highlighted key points
• Bullet points
• Abstract overview
• Synopsis
• Outline
• Paraphrase
• Rewrite
• Keywords
• Translation
• Quiz
• Flashcards
• Concept map
• My notes
• Chat with your text or summary

For studying, Summary AI can generate study notes, quizzes, and flashcards from your own text or summary. Test your understanding, review important ideas, and prepare for exams without rereading the same material again and again.

For work, summarize PDF reports, meeting notes, documents, research material, long emails, web pages, and articles. Get the main points faster and focus on decisions instead of reading every detail.

For reading and research, create a book summary, article summary, PDF summary, document summary, synopsis, or outline to understand the structure, key ideas, and important takeaways.

The chat feature lets you ask questions about your content. Clarify confusing sections, explore ideas, request examples, rewrite parts, or go deeper into a topic without leaving the app.

My notes lets you write, edit, and save your own notes inside the app. Keep personal thoughts, add context, store important takeaways, or turn a TLDR summary into your own study notes.

Summary AI also includes a curated catalog of popular book summaries. Use them before reading a book, after reading it, or when deciding what to read next.

1. Add text, a PDF, document, link, YouTube video, photo, scanned page, or book

What I like best about this app is that it doesn't just summarize text or articles. It offers additional very useful features. My favorite ones are the options to create quizzes or flashcards based on the text. However, I'm not a fan of the graphic user interface (which looks very outdated and clunky) and the fact you have to subscribe as opposed to paying a one-off fee.

This app sucks. You need to watch an ad to unlock the whole summary, and that takes an extra 30 seconds, which isn't good for a time saving app. Also, after a certain number of summaries, you need to watch another ad just to get the summary at all. I understand you need money, but you can at least make the ads skippable! One star all the way!

We are sorry for this, but to continue work on this free app we need revenue from Ads. If you don't want to see the Ads you can subscribe. Thanks for your understanding!

Just good. A few of the options (like summarizing a webpage into simpler terms) are not working for me; the app just reprints the first few hundred words or so from the original webpage. What does work, works well -- but I ended up using the "chat" feature to get what I needed. I can already do that with any AI chatbot around. Promising, but uninstalling for now. Will take a look again someday.
