Common questions

Is Summio cheaper than 4 Minute Books?+

4 Minute Books is free; Summio Premium is $39.99/year, but Summio adds open input from books, YouTube, articles, and PDFs plus a saved offline library.

Does Summio have audio narration?+

Not yet. Summio is text-first — every summary is a structured editorial read with chapters, quotes, takeaways and citations. If audio narration is the deciding feature for you, audio-first apps may suit better. Audio is on the Summio roadmap.

Can I import my 4 Minute Books highlights into Summio?+

4 Minute Books does not offer a public export of highlights at this time. With Summio you can paste any book title, YouTube URL, web link, or PDF directly — there is nothing to migrate. Your library lives inside Summio and follows your Apple ID.
