Yes. Summio is free to download from the App Store and includes a free tier. Premium and Max subscriptions unlock unlimited summaries, Dialogue, and advanced Practice.

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 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.

Does Summio work offline?

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.

Can I cancel anytime?

Yes. Subscriptions are managed through your Apple ID and can be cancelled at any time in Settings > Apple ID > Subscriptions on your iPhone. You keep access until the current period ends.

How much does Summio cost?

Is Summio a Blinkist alternative?

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.

Does Summio summarise YouTube videos?

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.

Can Summio summarise PDFs?

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.

How accurate are Summio AI summaries?

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.

Is Summio available on Android?

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.

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.

Can Summio turn summaries into audio or a podcast?

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.

Does Summio help you remember what you read?

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.

Domande frequenti

C’è un limite di durata del video?

In pratica no: Summio gestisce video di diverse ore. Le lezioni molto lunghe possono richiedere uno o due minuti di elaborazione.

Funziona con le playlist?

Sì. Incolla l’URL della playlist e Summio crea una raccolta in cui ogni video è riassunto separatamente con link incrociati.

Cosa succede se il video non ha sottotitoli?

Se mancano i sottotitoli di YouTube, Summio genera automaticamente una trascrizione dall’audio. L’accuratezza dipende dalla qualità audio.
