Summio — AI要約・単語カード・クイズ

ページ、PDF、動画をAIで要約し、単語カードやクイズに変換します。

Summio turns anything you read into something you actually remember. Open the side panel on any article, PDF, image or YouTube video and get a TL;DR plus the key points in seconds — with the source kept, so you can always check it. Then, in one tap, turn that summary into flashcards or a quiz. WHAT IT DOES • Summarize anything — webpages, PDFs (unlimited pages on Premium), images and screenshots, YouTube videos, and text you paste in. • Flashcards, automatically — every summary can become a deck. Cards are scheduled with SM-2 spaced repetition, so they come back right before you would forget them. • Quiz yourself — generate a multiple-choice quiz from any page and see what actually stuck. • Exam Oracle — predict the questions most likely to come up from the material you have saved. • Ask your sources — chat with a summary and get answers grounded in that page. • Track it — weekly goals, streaks and review history. • Export — Markdown, Notion, Anki. • 13 languages, and you can set the summary output language separately from the interface. ALSO ON IPHONE Summio AI Study is on the App Store. Summarize on your laptop, review the flashcards on the bus — summaries, decks and progress sync across the extension and your phone on the same account. FREE AND PREMIUM Free gives you 20 text summaries a day plus quota-limited image, PDF, chat and export access. Premium removes the limits: unlimited summaries, unlimited PDF pages, and the full study toolkit. 7-day free trial, no credit card. Premium is $9/month or $86/year on the web. Subscribing inside the iPhone app is $10.99/month or $99.99/year — the difference is the App Store commission, and either one unlocks Premium everywhere. PRIVACY Summio only reads a page when you ask it to. There is no background scraping and no selling of your data. Full policy: https://summio.app/privacy
