Gains:
- Ability to produce the summary, synopsis, back cover text (blurb) and single-sentence summary (logline) of a text in different lengths with the support of artificial intelligence.
- Ability to adapt AI output according to publisher/reader expectations for spoiler balance, arousing curiosity and accurate promotion
- Ability to check whether the promotional text produced by artificial intelligence reflects the reality of the text
The most difficult part of a text to write is often the shortest. Telling a 100,000-word novel on a single page, or even in a single sentence; condensing an article into one paragraph; Making readers love a book on its back cover - these are separate arts. Artificial intelligence (AI) is a powerful aid in compression and reframing: it can produce synopses, synopses, blurbs, and loglines of varying lengths. But it is up to the author to decide what to highlight, how to balance spoilers, and whether the introduction reflects the truth of the text. In this unit, we will cover these short but critical text types.
Let's get to know the types
Each promotional text has a different purpose, length and audience. Let's define it to avoid confusion:
Summary: It is a text that conveys the content of a text objectively and completely; usually includes the ending. Its purpose is to inform (e.g. executive summary of a report, abstract of an article).
Synopsis: It summarizes the plot of a fiction from beginning to end, including its turns and ending. Used for presentation to the publisher; It is written for the decision maker, not for the reader.
Blurb (back cover text): Marketing copy that persuades the reader to buy; It arouses curiosity but NEVER reveals the ending. Its purpose is to capture, not to explain.
Logline (single sentence summary): This is the formula that summarizes the story in a single, striking sentence; It is usually in the structure of "who + what wants + what obstacle". It's like an elevator speech.
The table below compares these types:
Genre
length
Does it explain the ending?
Who is the reader?
Summary
short-medium
Yes
information seeker
Synopsis
1-3 pages
Yes
Publisher/agency
Blurb
100-200 words
No (never)
potential buyer
Logline
one sentence
no
Everyone (hook)
Caution: Confusing these types is a common mistake. Putting the ending in Blurb kills sales of the book; Not including the ending in the synopsis will make the publisher angry (because they want to evaluate the ending). Tell the AI clearly which type you want and whether it will explain the ending.
Producing summary and synopsis
The biggest risk of AI when summarizing a long text is not being able to distinguish the important from the unimportant: sometimes it highlights a side detail, burying the main argument. So it is necessary to tell him what is the center.
Your role: summary assistant. Below is an article. My main claim: [single sentence]. The 3 most important supporting points: [n1, n2, n3]. Task: Produce a summary of 3 different lengths: 1) single sentence, 2) 50 words, 3) 120 words. Make sure to keep the main claim and 3 supporting points; omit side details.Do not add any information that is NOT in the text; do not exaggerate or add interpretation.
For the synopsis (fiction, publisher pitch):
Your role: synopsis assistant. Below is the plot summary of my novel.Task: Write a 1-page synopsis for the publisher. Includes: main character and his desire, central conflict, turning points, climax, and ENDING. Present tense, use third singular. Let the event and cause-effect come to the fore, not the emotion. The event that is not in the text is FAKE; just convey the actual plot.
Blurb and logline: the subtlety of marketing
Blurb is the most artistic type of promotion because it has to say little and create a lot of curiosity. A good blurb introduces the setup, establishes the tension, then stops just as he's about to explain the solution. AI is good at generating multiple blurb variations; you choose the most attractive one and adjust it to the reality of the text.
Your role: book marketing copy writer.Genre: [genre]. Tone: [tone]. Main character: [x]. Basic conflict: [y]. Curiosity hook: [question that attracts the reader]. Task: Write 3 different blurbs, 120 words each. Rule: NEVER reveal the END; Arouse curiosity but do not solve. Promising an event/genre that is NOT in the text (misleading promotion is prohibited).
For logline:
Task: Write 3 different loglines for the story below. Structure: [who] wants [what] but [obstacle/cost]. Make it striking and clear; do not reveal the ending; Avoid clichés.
Tip: To test a blurb, ask yourself: "Would someone reading this text find what was promised when they opened the book?" If the answer is no, blurb is misleading — it should be fixed, no matter how attractive it is. Charm cannot come before honesty.
The most critical control: fidelity to reality
The most dangerous tendency of AI in all these genres is to add what is not in the text for the sake of appeal. When summarizing a novel, AI can invent a non-existent turn of events; in a blurb it can make the book look more action-packed than it is; It may promise the wrong type in a logline. Result: the reader feels deceived, bad comments come, trust is lost. That's why the final check of every promotional text is one question: does it reflect the truth of the text? The promotion is the showcase of the book; Showing goods that are not on display is the most expensive mistake.
The power of the logline: the core of everything
The one-sentence logline is not just a promotional tool; It is also a compass. If you cannot tell a story in one sentence as "who + what wants + what obstacle/cost", it often means that the center of the story is not yet clear. That's why experienced writers establish the logline very early in the writing, rather than at the end, and return to it throughout the writing: "does this scene I wrote serve the central conflict in the logline?" AI is a good counter for logline experiments; But the sharpest logline often comes from your attempt to squeeze the essence of the story into your own words. Take the AI's suggestions as a starting point, then weigh each word for yourself: does each word point to the center of the story or is it ornamental?
Tip: Read your logline to a friend and ask “would you like to read this book?” ask. If the sentence doesn't spark curiosity, the problem is often not in the introduction, but in the fact that the core of the story isn't sharp enough.
three mini cases
Case 1 — Length flexibility. A researcher needed the same article as a tweet, an abstract, and an executive summary. He gave YZ the main claim and support points and had it produced in three lengths; checked each one for accuracy and published it. Work that would take hours has been reduced to minutes.
Case 2 — Misleading blurb. One writer used the AI-generated blurb as is; blurb was promoting the book as a thriller, whereas the book was a quiet family drama. Readers left negative comments saying "this is not the promised book". The comments improved when the author rewrote the blurb according to reality. Lesson: charm can't trump reality.
Case 3 — Contrived return. An author had the synopsis of his novel written by AI; AI added a "betrayal twist" that was never in the book because he wanted to make the synopsis more interesting. The author captured this and removed it. It's a good thing he checked; A false plot would be presented to the publisher.
Weak prompt / Strong prompt
Weak prompt:
Write a nice back cover text for my book.
The result: an obscure, factual, perhaps misleading text.
Powerful prompt:
Your role: book marketing copywriter. Genre: family drama (NOT action). Main character: A 50-year-old carpenter. Main conflict: confrontation with his daughter returning after many years. Tone: warm, melancholic. Curiosity hook: why didn't they talk for years?Task: 3 blurbs (120 words each). OPENING the ending; DO NOT ADD an event/genre that is not in the text. Write a note "to which reader does it appeal" under each one.
The difference: genre, tone, real event, and the ban on "fabrication" is clear; It turned out both attractive and honest.
Common mistakes
- Mixing genres. Putting an ending in Blurb or removing an ending from the synopsis defeats the purpose.
- Adding what is not in the text for the sake of appeal. Misleading promotion destroys trust and reviews.
- Not telling the AI the main claim. AI cannot find the center, it highlights the side detail.
- Being satisfied with one version. It is much more powerful to ask for several variations and choose the best one.
- Bypassing the truth fidelity check. The showcase must display the goods inside correctly.
In summary
Summary, synopsis, blurb and logline; They are separate works of art, each written for different purposes, lengths and readers. AI is a powerful aid in generating compression and variation: it tries different lengths in minutes. But it is the writer's job not to mix genres, to balance spoilers, and most importantly, to ensure that the introduction reflects the reality of the text. Charm can never trump honesty. AI compresses text; You decide what stands out and fidelity to truth.
Application task
Select a text (article or fiction). First, write the main claim/gist of the story yourself in one sentence. Ask AI for three length summaries and three blurb variations with the templates in this unit. Check each output with the question "has anything been added that is not in the text?" and “does it reflect reality?” Check with questions. Choose one of the blurbs and rework it according to the truth of the text.
checklist
- [ ] Have I clearly specified the type I want (summary/synopsis/blurb/logline) and whether it will open the ending?
- [ ] Have I given the main claim/gist to the AI myself?
- [ ] Have I checked whether an event/promise has been added in the output that is not in the text?
- [ ] Did I make sure I didn't reveal the ending in Blurb?
- [ ] Have I verified that the description reflects the truth of the text?
- [ ] Did I ask for multiple variations and choose the best one?
