Yes. You can start in the Web app or download the iOS app from the App Store. A free tier is available; paid plans increase eligible usage limits and features.

What languages does Summio support?

Summio supports 27 interface languages including English, Spanish, French, German, Portuguese, Italian, Russian, Arabic, Japanese, Korean, Simplified Chinese, and Traditional Chinese.

What can Summio summarise?

Four source types: eligible catalogue books, public YouTube videos with usable transcript context, compatible public articles, and compatible text-based PDFs within product limits. For eligible sources, a supported output language can be selected.

Does Summio work offline?

Generating summaries and using AI chat requires an internet connection. The Web app is online; offline availability in the iOS app depends on content already saved on that device.

Can I cancel anytime?

Yes. Manage or cancel through the provider used for purchase: App Store subscription settings for Apple purchases, or the Web billing portal for eligible Stripe purchases. Access normally continues through the paid period, subject to the provider terms shown at checkout.

How much does Summio cost?

Summio includes a free tier and paid Premium and Max plans. Current price and renewal terms are shown at checkout. Web purchases are processed through Stripe; purchases in the iOS app are processed by Apple.

Is Summio a Blinkist alternative?

Summio may fit readers who want summaries for eligible catalogue books, public YouTube videos with usable transcript context, compatible public articles, and compatible text-based PDFs. Chat uses the summary and available source context; Summio does not distribute full copyrighted books. Verify Blinkist's current product on its site before comparing.

Does Summio summarise YouTube videos?

Yes. Paste an eligible public YouTube lecture, podcast, or talk URL. Supported videos with available transcript context can be summarised, timestamps appear when available, and chat can use the available transcript context.

Can Summio summarise PDFs?

Yes. Upload a compatible text-based PDF up to 50 MB and 1,000 pages. Image-only scans need OCR before upload. Eligible files can produce a structured summary plus chat with available document context; see the Privacy Policy for data handling and provider terms.

How accurate are Summio AI summaries?

Citations point to relevant source sections or passages when available. AI can still err — Summio is a reading companion, not a substitute for the original work for medical, legal, financial, or academic decisions.

Is Summio available on Android?

Summio has a Web portal that can be used from a compatible browser, plus an iOS app for supported Apple devices. A native Android app is not currently advertised.

Summio is built by a small independent team. It is not part of a larger publisher. Contact: support@summio.org for support and privacy@summio.org for privacy questions.

Common questions

Is there a maximum video length?

Processing depends on the public video, available transcript, and current product limits. Very long or unsupported videos may not be accepted.

Does it work with playlists?

Support depends on the URL and current product limits. If a playlist URL is not accepted, add an eligible public video individually.

What if the video has no captions?

A supported, available transcript is required for this flow. Videos without usable transcript context may not be accepted.
