Shorten Any Text Online — AI Book Summaries, Key Points and Notes
A chapter-by-chapter book summary, an article digest or lecture notes — in about a minute, at exactly the length you need.
How to get a summary in 3 steps
Paste an article, report or lecture transcript — or just name the book and author if it's a well-known work.
Pick a card: short summary, chapter by chapter, key ideas as a list, or structured notes. State the target length in the prompt — from three sentences to a page.
Ask it to expand a particular chapter, simplify the language or add takeaways — the AI adjusts the summary right in the conversation.
Part of the Zerocoder platform
One tool of a platform where AI generates websites, images, video, text and documents — under one subscription.
Summaries help students before exams, readers keeping a journal, and anyone who deals with long documents at work. The Zerocoder AI shortens text without losing the point: it pulls out key theses, retells books chapter by chapter and turns lectures into structured notes. A summary is also a great starting point for other work: the report generator shapes material into an academic structure, the AI text generator expands your outline into full prose, and it's worth running the final draft through the spelling and grammar checker. First credits are free. For structured study notes on a topic, use the dedicated notes generator.
Why AI summarizing beats sentence extraction
Older summarizers worked extractively: they picked "important" sentences out of the text and stitched them together, which is why the result often fell apart logically. A language model works differently — it rebuilds the condensed text in its own words while preserving cause-and-effect links, so the summary reads as a coherent piece. Compression is adjustable on demand: "one sentence", "10 bullet points", "one page". A useful trick is asking for two levels at once — a three-sentence digest first, then a detailed retelling — and reading only as deep as you need.
Book summaries: where the AI is strong and where to verify
The model handles classics and well-known non-fiction confidently: it knows the plot of major novels and the ideas of bestselling titles from its training data. With rare, brand-new or niche books, names, dates and the order of events can come out wrong — that's a model hallucination. The rule of thumb: if the summary feeds a grade or a work decision, verify key facts against the source, or paste excerpts of the book into the request — when summarizing your own text, the AI sticks to it without inventing anything. You can also ask the model how confident it is in the details.

FAQ
Can I shorten a text to an exact word count?
Yes — state the target in the prompt: "under 100 words", "5 sentences", "half a page". The AI holds the limit quite precisely, and if the result runs long, just ask it to compress once more.
Can it make notes from a webinar recording?
Yes, if you have a text transcript — paste it and the AI builds notes with headings, definitions and takeaways. Split a long transcript into chunks of 10–15 thousand characters and ask it to merge the notes at the end.
How accurate is a summary of my own text?
When you paste the full text, the AI works only with what you gave it and adds nothing of its own — that's the most reliable mode. Check that the emphasis matches yours, and ask it to strengthen a specific point or restore a missing fragment if needed.
Can it summarize in another language, or translate as it goes?
Yes, the AI condenses texts in dozens of languages and can combine tasks — for example, summarize a French article directly in English. Just name the output language in the prompt.
What's the difference between a summary and notes?
A summary is a coherent condensed retelling of the content. Notes are a structured document with headings, definitions, lists and takeaways — handy for revising before an exam. Pick the matching card and the output format changes accordingly.
Will it help me prep for a literature exam?
Yes: a chapter-by-chapter retelling restores the plot quickly, and a key-ideas list brings back the themes. But essays and oral answers need details and quotes, so treat the summary as a map of the book, not a substitute for reading it.
