Question 4

Does Summio work offline?

Accepted Answer

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.

Question 5

How much does Summio cost?

Accepted Answer

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.

Question 7

Is Summio a Blinkist alternative?

Accepted Answer

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.

Question 8

Does Summio summarise YouTube videos?

Accepted Answer

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.

Question 9

Can Summio summarise PDFs?

Accepted Answer

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.

Question 10

How accurate are Summio AI summaries?

Accepted Answer

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.

Question 11

Is Summio available on Android?

Accepted Answer

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.

Question 12

Who built Summio?

Accepted Answer

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.
