Depths, accuracy and what a plan includes

Three depths. Ultra brief is a few paragraphs, medium covers the argument section by section, and detailed keeps chapter-level structure. Read aloud they run roughly six, fifteen and forty-five minutes.
No. You can summarise a book in its original language, or summarise the translation once you have run one. Many people summarise first precisely so they can decide whether the full translation is worth it.
The free plan includes one book summary and one short summary listen a month. Starter includes twenty summaries, Pro sixty. Allowances reset at the start of each month.
Yes, and summary narration is included in the plan rather than bought per book. That is the difference from a whole-book audiobook, which is priced by how long it runs — see AI audiobooks.
It is generated from the book's own text, so it does not invent a plot the book does not have. It is still a machine reading: good for deciding, discussing and orienting yourself, not a substitute for the book if the detail matters.
Three depths
The three lengths exist because there are three different decisions you might be making. Picking the wrong one wastes the summary.
What the book is and who it is for, in a few paragraphs. The one to use when triaging a list of twenty titles down to three.
The argument with its main turns, section by section. Enough to discuss the book, and enough to decide whether to translate it in full.
Chapter-level coverage that keeps the structure of the original. The one to use when you need the content rather than the verdict.
Summary narration
Every summary can be read aloud with the same voices as a full audiobook. Six, fifteen or forty-five minutes depending on the depth — and it is included in your plan.
The free plan includes one summary and one short summary listen a month.

Three hundred pages is a serious commitment in a language you read slowly. A summary at the depth you choose tells you what the book is, what it argues and whether it is worth your hours — in six minutes rather than six evenings.
Summaries first
Most abandoned books were abandoned because they were the wrong book, and that only became obvious around chapter four. A summary moves that discovery to the front.
