What languages does Summio support?

Question 3

What can Summio summarise?

Accepted Answer

Four sources: full-length books, YouTube videos of any duration, web articles, and PDF documents. Every summary is generated by AI in the language you choose.

Question 4

Does Summio work offline?

Accepted Answer

Generating new summaries and using Dialogue requires an internet connection because the AI runs in the cloud. Once a summary is created, you can re-read it offline inside the app.

Summio is free to download and includes a free tier. Premium is $4.99 per month or $39.99 per year. Max is $9.99 per month or $79.99 per year. Yearly plans save 33% versus monthly. All payments are processed by Apple.

Question 7

Is Summio a Blinkist alternative?

Accepted Answer

Yes, but with a wider scope. Blinkist offers a curated catalogue of book summaries; Summio summarises any book, YouTube video, long-form article, or PDF you point it at — on demand, in 27 languages, with chat over the full source text.

Question 8

Does Summio summarise YouTube videos?

Accepted Answer

Yes. Paste any YouTube URL — lecture, podcast, talk, or playlist. Summio fetches the transcript and produces a clean editorial summary with timestamps preserved. You can chat with the full transcript afterwards.

Question 9

Can Summio summarise PDFs?

Accepted Answer

Yes. Upload research papers, manuals, reports, even scanned books. OCR runs automatically when needed. The PDF stays inside your account and never leaves it. You get a structured summary plus an inline chat over the full document.

Question 10

How accurate are Summio AI summaries?

Accepted Answer

Every claim in a Summio summary points back to a passage in the source. If the engine cannot ground a claim, it is not printed. AI is not perfect — Summio is a reading companion, not a substitute for the original work for medical, legal, or financial decisions.

Question 11

Is Summio available on Android?

Accepted Answer

Not at launch. Summio is iPhone and iPad only on iOS 18 and later. An Android version is on the roadmap but does not yet have a date.

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.

Question 13

Can Summio turn summaries into audio or a podcast?

Accepted Answer

Yes. Every summary can be played as natural audio narration, chapter by chapter — listen on a commute, a walk, or while doing chores, just like a podcast.

Question 14

Does Summio help you remember what you read?

Accepted Answer

Yes. The learning companion uses spaced recall and gentle reminders to bring the key ideas back before you forget them, so a finished summary actually sticks.
