How to Use an AI Book Idea Generator

Book ideas often begin as a spark: a few intriguing words overheard in conversation, the impression left by a painting, or a dilemma at the heart of a news story. The next step is to take that fleeting spark and shape it into a fully formed story idea, which is where an AI book idea generator—such as QuillBot’s free AI book generator—can help.

How to come up with a book idea

Books often hinge on a central character who strives for something but finds that an obstacle is standing in their way. Here are some ways of coming up with ideas for a protagonist, what they desire, and the conflict that compels the reader to turn the page.

Central character

Your inspiration for a main character could be:

  • Someone you know
  • An interesting-looking person in a painting, photograph, or internet image
  • Your impressions of a stranger you observe on a train or in a café
  • An intriguing public figure
  • A famous or overlooked individual from a historical period that fascinates you

Desire

Central characters in a novel often long for things like:

  • Love, belonging, or acceptance
  • Power, status, or recognition
  • Freedom or independence
  • Wealth or material comfort
  • Revenge or justice
  • Knowledge, truth, or understanding
  • Adventure, excitement, or escape
  • Safety, stability, or peace

Conflict

What stands in the way of your character’s desire might be:

  • Another person with opposing goals
  • Social expectations, prejudice, or stigma
  • Laws, rules, or institutions that restrict them
  • Family obligations or loyalties pulling them in another direction
  • Their own fears, flaws, or self-doubt
  • A rival, enemy, or competitor
  • Circumstances beyond their control (poverty, war, natural disaster)
  • A moral dilemma that forces them to choose between what they want and what is right

Using an AI book idea generator
