Question 1

Can I really summarize a book just from a photo of the cover?

Accepted Answer

Yes — for any well-known published book. Upload a clear photo of the cover and Gemini 3.1 Flash Lite recognizes the title/author, then uses its training knowledge to generate the summary. If the book is too obscure or the cover is unreadable, you'll see a friendly message asking you to use title + author mode or paste text instead.

Question 2

What's the difference between the 4 input modes?

Accepted Answer

(1) Title + Author: just type — best for classics and bestsellers. (2) Photo of Cover: snap/upload the book jacket — AI reads it. (3) Upload: PDF, EPUB, or DOCX file — we extract and summarize the actual text. (4) Paste Text: drop excerpts or full chapters you already have.

Question 3

What are the 6 summary depths?

Accepted Answer

Blurb (1 paragraph hook) · Executive (3 paragraphs) · Chapter-by-Chapter (structured per chapter) · Full Synopsis (10-15 paragraphs comprehensive) · Study Guide (for book reports — themes, analysis, essay angles) · Reading Notes (key takeaways + highlighted quotes).

Question 4

What extras are included?

Accepted Answer

Every summary includes: Character list (role + 1-line description, for fiction) · Theme analysis (3-5 major themes with evidence) · Key quotes extracted · 8 discussion questions (book-club style) · 3 similar book recommendations.

Question 5

How is this different from Blinkist?

Accepted Answer

Blinkist has 7,000+ curated books locked behind $14.99/mo. We let you summarize ANY book you can name or scan — recent, obscure, academic, self-published, niche — not just Blinkist's curated list. Plus 3 free uses, no account needed.

Question 6

How long of a book can I upload?

Accepted Answer

PDF/EPUB/DOCX up to 20MB (typically 600+ page novels fit). For truly massive academic tomes, the Chapter-by-Chapter mode focuses on each chapter's key points.

Question 7

What languages are supported?

Accepted Answer

40+ output languages. You can summarize an English novel in Spanish, or a Japanese book in English — cross-lingual works on known books.

Question 8

Can I export the summary?

Accepted Answer

Yes — copy to clipboard, download as .txt, or export to .md (Markdown) for pasting into Notion / Obsidian / Google Docs.

Question 9

Is this accurate for academic books?

Accepted Answer

For well-known academic works (e.g., 'Thinking, Fast and Slow', 'Sapiens', course-standard textbooks), yes. For highly technical or obscure works, upload the PDF for direct text-based summarization instead of relying on recall.

Question 10
