Example: all of Frankenstein, one page
We opened the complete Project Gutenberg Frankenstein (75,379 words) in the generator and chose One page. Look for what an agent expects: names in capitals the first time, present tense throughout, every turning point in order, and the ending stated plainly in the last paragraph.
On a polar expedition, Captain WALTON rescues VICTOR FRANKENSTEIN from a drifting ice floe. Frankenstein is exhausted and pursuing a gigantic being across the Arctic. As he recovers aboard Walton’s ship, he warns the captain against the reckless ambition that has ruined his life, then recounts his history. Raised in Geneva amid a loving family, Frankenstein grows close to his cousin ELIZABETH and his friend HENRY CLERVAL. At university in Ingolstadt, he becomes consumed by natural philosophy and discovers how to give life to dead matter. Working in secret, he assembles a giant humanlike creature and animates it. Horrified by its appearance, he abandons it. The creature disappears, while Frankenstein falls gravely ill and Clerval nurses him back to health. When Frankenstein returns to Geneva, his young brother WILLIAM has been murdered. He sees the creature near the crime scene and realizes it is the killer, but keeps silent, convinced nobody will believe his story. A miniature taken from William is found on JUSTINE, a beloved family servant, and she is convicted after a coerced confession. Frankenstein knows she is innocent but cannot save her. Her execution deepens his guilt and leaves his family grieving. In the Alps, the creature confronts Frankenstein and tells his own story. Newly alive, he learns to speak and read by secretly observing the De Lacey family, whom he aids in their poverty. He hopes their kindness will extend to him, but when he reveals himself, they flee in terror. Rejected and driven into rage, he burns their cottage. Later, after saving a girl from drowning, he is shot by a man who assumes he means her harm. Near Geneva, he tries to seize William as a companion, but the boy recoils and names Frankenstein as his father. The creature kills him and plants the miniature on Justine. He demands that Frankenstein create a female companion, promising to leave humanity with her forever. Frankenstein reluctantly agrees. Frankenstein travels to a remote Orkney island to make the second creature. But fearing the pair might reject each other, produce offspring, or threaten humanity, he destroys his unfinished work. The creature witnesses this and vows revenge, promising to be with Frankenstein on his wedding night. Soon afterward, he murders Clerval. Frankenstein is arrested in Ireland, where the body is found, but is acquitted when witnesses establish he was on the Orkneys at the time. He returns to Geneva and marries Elizabeth, misreading the creature’s threat as a promise to kill him. On their wedding night, the creature murders Elizabeth instead. Frankenstein’s father dies from grief, and Frankenstein, briefly imprisoned as a madman, escapes and swears to hunt his creation. His pursuit carries him across Europe and Russia and onto the polar ice. Walton’s crew, trapped by ice and afraid to continue north, compel the captain to turn back. Frankenstein dies before he can reach the creature. The creature enters the cabin, mourns his creator, and admits that remorse has not undone his crimes. He says he will travel to the northernmost reaches and burn himself on a funeral pyre so no one can repeat Frankenstein’s experiment, then leaps from the ship onto an ice raft and disappears into the darkness.

Notice it starts with Walton's ship, the way the novel does. A human editor might open with Victor instead; that is the kind of choice you should still make yourself.
The synopsis rules agents expect
Agents and editors differ on length, so check each agency's submission page. On the rest they mostly agree:
- Tell the ending. "Don't worry about spoilers. And do include how it ends," writes former agent Nathan Bransford. London's DHH Literary Agency asks for "no cliffhangers".
- Third person, present tense, even if the novel is first person or past tense.
- Capitalize each main character's name the first time it appears. Bransford calls this optional; Jane Friedman and Jericho Writers recommend it.
- Few names. Agent Ammi-Joan Paquette suggests naming just two or three characters in a one-page version.
- Plain, neutral language. No rhetorical questions, no themes, no sales talk. That belongs in the query letter.
| Source | Recommended length |
|---|---|
| Jane Friedman | One or two pages, about 500–1,000 words, single spaced |
| Jericho Writers | About 500–800 words; a UK “one page” is 400–500 words at 1.5 spacing |
| Nathan Bransford | 1.5 to 4 pages single spaced; 1.5 to 2.5 is the sweet spot |
| Writer's Digest (Paquette) | Long form: about one page per 10,000 words of manuscript |
| DHH Literary Agency | A single page |
Synopsis, query, blurb or logline?
| Name | Who reads it | Ending? | Length |
|---|---|---|---|
| Logline | Agents, producers, anyone you pitch in person | No | One sentence |
| Query letter | Agents, before anything else | No | About 300 words |
| Blurb | Readers, on the back cover and Amazon | Never | 150–200 words |
| Synopsis | Agents and editors deciding whether the plot works | Always | About 500–1,000 words |
Before you send it: a five-minute check
- Is the ending in the last paragraph, stated plainly?
- Can a stranger tell what the main character wants, what stops them and how they change?
- Are only two to four characters named?
- Does it fit the agency's length? Switch between One page and Two pages if not.
- Have you rewritten the sentences that don't sound like you? Read it aloud once.

Querying agents in another country?
Choose the agent's language under "Write it in" and the synopsis is written in that language from your manuscript. If they ask for sample chapters too, our AI novel translator translates the whole manuscript in one go, with names kept consistent from the first chapter to the last. Have a native reader check both before you send them.
FAQ
Synopsis questions
Can AI write a synopsis?
Yes. It is good at the part writers find hardest: squeezing a whole novel into one page without losing the plot. Treat the result as a solid first draft and rewrite it in your own voice before you send it.
What is the format of a synopsis?
Plain prose paragraphs, third person, present tense, with each main character's name in capitals the first time. It follows the story in order and ends with the ending. Agents usually expect Times New Roman 12 point.
How long should a synopsis be?
One page, about 500 words, is the safest default. Some agents accept two pages (about 1,000 words). Always follow the agency's own submission guidelines.
Should a synopsis include the ending?
Yes, always. Agents want to see that the story resolves. Never end a synopsis on a cliffhanger; that is what a blurb does.
Is there a free AI synopsis generator?
This one is free with no sign-up, and it reads a whole manuscript from a Word, PDF, EPUB or text file. A quick Cloudflare check keeps bots out; most people never see it. If many people use it in the same hour you may be asked to try again a little later.
Is it legal to use AI to summarize my book?
Summarizing your own manuscript raises no copyright problem. Some agents and publishers ask whether AI was used in a submission, so read their guidelines and edit the synopsis so it is yours.
Is my manuscript stored?
No. Your text is sent to the AI model to write the synopsis and is not saved by PageTranslate.
How long does it take?
Usually 15 to 30 seconds, even for a full-length novel. Our whole Frankenstein example took 13 seconds.
