How to Write a Blurb with AI

Blurb writing has always been my personal nightmare. I’ve written entire books faster than I’ve managed to wrangle one of those tight, punchy paragraphs that are supposed to turn a browser into a buyer. If you’ve ever found yourself dreading this step, you’re in good company.

From the very beginning, I knew I needed help. Hiring a professional blurb writer was out of my budget, and even when I did manage it, the results were hit or miss.

Nobody knows your book quite like you do, and it turns out nobody else can always nail the heart of your story on the first (or third) try.

What finally saved me was learning how to write blurbs with AI. Not only did I start getting better blurbs, I suddenly had options: a stack of versions to test, tweak, and run past readers. That changed everything.

Here’s exactly how I write a blurb with AI, step by step, and how I know when it’s actually good enough to use.

Why Blurbs Matter (and Why Most of Us Hate Writing Them)

The blurb is the first impression your book makes, often before a reader even glances at the sample. It’s your book’s sales pitch and its front door, all rolled into a few tight paragraphs.

If the blurb doesn’t grab them, nothing else will. Most of us know that, which is why writing one feels so intimidating.

For authors, it’s personal.

We know every twist, every layer, every reason this book matters. Boiling all of that down to a few lines that make someone want to buy is a whole different skillset. It’s no wonder we dread it.

Blurbs demand clarity, confidence, and emotional punch, but the process often feels like wrangling a wild animal with oven mitts.

What Actually Goes Into a Strong Blurb

After years of wrestling with blurbs, I’ve learned there are a few things you can’t skip if you want your blurb to actually convert.

First, you need to get the tropes up top.

I used to bury them somewhere in the middle, thinking I was being clever, but all it did was make the right readers miss what they came for.

If your book is grumpy/sunshine or secret baby or sports romance, say so immediately. It’s about setting expectations and hooking the people who love those exact things.

Then comes the hook.

Your first line isn’t just a formality. It’s your one chance to keep someone from scrolling away.

This is where you grab attention with something specific to your story, not just a recycled one-liner. Think less “Will they risk it all for love?” and more “Harper only signed up for one fake date, not a season with the team’s biggest flirt.”

Heat level and tone have to be clear.

If your book is steamy, readers should pick up on it before they’re halfway down the page.

Same goes for emotional, funny, or suspenseful. Let your blurb match the book’s real mood.

Now, the core conflict is what holds everything together.

Ask yourself:

  • WHAT is the main character’s problem?
  • HOW are they trying (and failing) to solve it?
  • WHY can’t the couple be together from the start?

And don’t forget to end on a question. The last line should leave readers wanting answers. It’s not just about teasing the plot, but making sure the person reading needs to know what happens next. Something like, “Can she keep her secret when the world’s watching?”

How I Use AI to Write a Blurb (Step by Step)

No magic tricks here. Just a system that keeps me out of blank page hell. AI is my secret weapon, but it only works if you set it up right.

Step One: Start with a tight outline.

I always begin with a one-paragraph-per-chapter outline. Nothing fancy, just a clear road map that covers the story arc and big emotional beats. This helps the AI see what matters, not just who kisses whom.

Step Two: Gather the right examples.

Before I bring in the AI, I collect two or three blurbs from recent bestsellers in my genre or niche. I don’t bother with blurbs from ten years ago or ones that feel nothing like my book. I want examples that match my heat level, my POV, and the tropes I’m working with. These become the blueprint for what I want.

Step Three: Spell out your essentials.

I list the things the AI must include. Tropes, POV, heat level, any detail unique to my story. This is the part most people skip, but it saves a lot of pain later.

Step Four: Give clear instructions.

I paste everything into the AI—the outline, the example blurbs, and my list of must-haves. Then I make the request specific. I don’t say, “Write a blurb.” I ask for multiple versions and I’m clear about what matters:

  • Start with a strong hook.
  • Hit the tropes up top.
  • Keep it under 200 words (though do notes, most LLMs can’t count).
  • Match the tone and POV of my examples.
  • End with a question or mini cliffhanger.
Step Five: Review, combine, and edit.

The AI always gives me a range and I pull the best bits, stitch them together, and rewrite anything that feels too generic or off-brand. If nothing works, I nudge the AI with more feedback or new examples and go another round.

Ready for the actual prompt I use? Here’s how I set up the request.

My Actual Blurb Prompt

Here’s exactly how I ask the AI for what I need. You can tweak the details for your genre, POV, or tone, but this is the core of my process:

<Insert Book as an attachment or Outline of Book>

Read <Book Title> attached / Read the [outline] above.

Then read the below examples of blurbs from the same genre:

[Example Blurbs]

Example Blurb 1: <Insert Example Blurb 1>

Example Blurb 2: <Insert Example Blurb 2>

Example Blurb 3: <Insert Example Blurb 3>

[/Example Blurbs]

Now, using the book details and [example blurbs] above, write five compelling blurbs for <Insert Book Title> in first-person POV from <Main Character>’s perspective.

Each blurb should:

  • Open with a hook that highlights the main tropes and immediately grabs attention.
  • Establish the main character’s problem and how they’re trying to solve it.
  • Clearly define the romantic conflict—what’s keeping them apart and why.
  • Highlight the emotional push and pull between the characters—the longing, the fear, the need, and the resistance.
  • Signal the heat level and tone naturally through voice and word choice.
  • End with a mini-cliffhanger that leaves readers desperate to know what happens next.
  • Include the hero’s status in a way that feels natural.

Remember, the best blurbs make the reader feel something, whether it’s tension, heartbreak, desire, or laughter. Don’t just set up the plot, make them care.

Write each blurb in <first person>, <present/past> tense from <character> POV. Remember it needs to be hooky, really emphasising the tropes in a natural way and hook the readers with a mini-cliff hanger that leaves them desperate to know what happens next.

Remember to use the [example blurbs] to inform formatting. We want short easy to read sentences and paragraphs.

Re-read the [example blurbs] and identify why those blurbs work to sell a book and hook readers in. The blurb must incite emotion. The mini-cliffhanger must be whether she can resist him. Each blurb should be 200 words.

Common Pitfalls to Avoid

Using AI for blurb writing is a massive time-saver, but it comes with its own set of traps. Here’s what I see most often (and what I’ve done myself more than once):

  • Letting the AI flatten your style. If your blurb sounds like it could belong to any other book in your genre, it needs another pass. Always edit for your voice and the unique flavor of your story.
  • Overstuffing. There’s a temptation to squeeze every subplot and every character into the blurb. Resist. You want clarity, not confusion. Stick to the main arc, the emotional hook, and the biggest stakes.
  • Missing the hook. If the first line isn’t grabbing attention, readers are scrolling on by. Don’t let the blurb open with backstory or worldbuilding—lead with something that makes readers care.
  • Ignoring the tropes and heat level. Hiding your tropes or playing coy about the book’s tone only hurts you. The right readers are looking for what you offer—make it easy for them.
  • Trusting word count. AI is notorious for ignoring length requests. Always check that the blurb is tight and scannable, not a rambling mini-synopsis.
  • Settling for “good enough.” Just because the AI gave you five blurbs doesn’t mean you’re done. Test, tweak, and swap lines until it actually sounds like a blurb that will sell your book to the right readers.
  • Treating the AI as infallible. Sometimes, the best blurb is the one you kitbash from multiple drafts, or the one you build from a single killer line buried in the middle of version three.
