AI Summarizer FAQ

Is Synt's AI summarizer free?

Yes — in your browser at app.synt.app or as an app on iOS and Android. You can create your first summaries without paying; Pro unlocks unlimited summaries and longer documents.

Can I use it on my computer, without installing anything?

Yes. Go to app.synt.app in any browser, create a free account and you get the same summaries, quizzes and flashcards as in the app; your material syncs between your phone and your computer.

What can the AI summarizer process?

Plain text you paste in, PDF files, and photos of printed pages or handwritten notes. Synt extracts the content and produces a structured summary of the key ideas.

How long can the text or document be?

Synt handles everything from a single paragraph to full textbook chapters and research papers. Long documents are analyzed section by section so nothing important is lost.

How is Synt different from asking a chatbot?

Synt is built for studying: summaries are structured around key concepts, and you can turn any summary into flashcards or a practice quiz with one tap — something generic chatbots don't do.

Does it work in my language?

Yes. Synt summarizes content in English, Spanish, Italian, Portuguese, French, German and many more languages, and answers in the language of your document.
