How to use the ebook idea generator

  1. Name your topic and your reader. The narrower, the better: "strength training for women over 40" gives sharper ideas than "fitness".
  2. Pick your goal. A lead magnet, a paid ebook, a book that builds your authority, or a companion to a course each call for a different kind of idea.
  3. Say how much you know. Beginners get ideas they can write honestly, like a starter checklist or a learning journey. Experts get ideas that teach their method.
  4. Get ten ideas, each with a title, an angle, a format and a rough length. Copy the ones you like, or press Make this in Koobe to start the book with that idea filled in.

How to choose an ebook idea

A good ebook idea is one you can write well, that a specific reader wants, and that fits what you're trying to do. Before you pick, check each idea against these questions:

  • Is the reader clear? "New managers promoted from their own team" is a reader. "Anyone interested in leadership" isn't.
  • Does it solve one problem? Ebooks that promise one result are easier to write, easier to name and easier to sell.
  • Can you write it from experience? Your own stories, numbers and mistakes are what make the book worth reading.
  • Do people already look for it? Search the topic on Amazon and see what's selling, read the reviews of similar books, and note what readers say is missing.
  • Is it the right size? A focused 30-page guide often beats a 200-page book nobody finishes. Our guide to how long an ebook should be helps you plan it.

Ebook idea examples

Strength training for women over 40: Form First

For busy beginners who’ve never lifted, written by an expert as a paid ebook. One of the ten ideas: “Form First: How to squat, hinge, push, pull and carry safely, with the common mistakes to avoid.” A visual technique guide with cue cards, 60 to 80 pages.

Same niche, a different angle: Gym Language Decoded

From the same run, a much smaller idea: “Sets, reps, tempo, RPE and every other term explained in plain English.” An illustrated glossary of 20 to 30 pages, suggested as a gentle first product.

Side hustles for nurses: Rules Before You Start

Asked for lead magnet ideas, the generator suggested a 4 to 6 page checklist of questions to ask an employer and licensing board before starting anything. Its own note: point readers to official sources rather than give legal advice.

Ebook idea generator FAQ

How do I pick a good ebook topic?

Pick something you know well, for a reader you can describe in one sentence, that solves one clear problem. Then check that people already look for it: search Amazon for similar books and read their reviews to see what readers wish were there. Run the generator a few times with different readers or goals and compare the ideas side by side.

How long should my ebook be?

As long as it takes to keep its promise, and no longer. Lead magnets are often a few thousand words, while practical how-to ebooks often run 20,000 to 40,000 words. Each idea here comes with a suggested length, and our guide on how long an ebook should be has typical ranges by type.

Can I write an ebook on a topic that already exists?

Yes. Most good ebooks cover topics that already have books. What makes yours worth buying is the angle: a specific reader, your own method or examples, or a format the others don’t offer, like a workbook instead of a long guide. That’s why every idea here comes with an angle, not just a topic.

Can an ebook work as a lead magnet?

Yes. A short ebook, checklist or workbook is one of the most common lead magnets: people get it free in exchange for their email address. Choose “Lead magnet” as the goal for ideas sized for it, or use the lead magnet generator for hooks, outlines and opt-in copy.

How do I know if people will want it?

You can’t know for sure, but you can look for signs. Search the topic on Amazon and see whether similar books sell and get reviews, look at the questions people ask in forums and groups, and ask a few people from your audience which idea they’d want. The reasons the generator gives are opinions, not market research.
