This page is designed to help you find out whether Neolemon is good and if it is the right choice for you.
Neolemon makes cartoon storytelling easy. Create cartoon characters from a description, a photo or your own art, keep them consistent on every page, and publish your illustrated children's book.
ChatGPT and Midjourney are great for single images. Neolemon is built for the whole book: the same character on page 27 as on page 3, plus the trim, bleed, cover wrap and 300 DPI files that KDP accepts. Compared with hiring an illustrator, it takes days and $29 a month instead of months and thousands of dollars.
First-time authors with a finished story, KDP self-publishers building a series, parents making personalised books from family photos, and teachers. About 60% publish on KDP.

Writers with a story and no way to illustrate it. Most paying customers are first-time or self-taught authors who already have a manuscript, often one they’ve carried for years, and want a finished picture book. About 60% publish on Amazon KDP, and many go on to build a series. Others are parents making a personalised book from family photos as a gift, and teachers creating classroom stories. What they share: they see themselves as storytellers, not artists or AI experts, and they need the same characters on every page.
The core image generation uses proprietary AI models optimized for character consistency, leveraging reference-based conditioning rather than text-only prompting. The platform runs as a web application with cloud-based processing, requiring no software installation.
Four reasons.
It covers the whole book. ChatGPT and Midjourney are great for single images. Neolemon is built for page 27 matching page 3, then the layout, text, speech bubbles and print-ready KDP file, all in one place. You change one thing at a time. Separate editors for pose, expression, outfit, camera angle and background change only what you ask for, and the rest of the page stays put. It’s made for writers, not AI experts. Describe what you want in plain words, in any language, typed or spoken. A free 37-minute masterclass builds a complete book live. Your book stays yours. Your work is never used to train AI, and paid plans include full commercial rights for KDP, IngramSpark and print services.
Neolemon is rated 4.7 on Trustpilot, and first time authors have successfully published books on Amazon.
Neolemon takes a children’s story all the way to a finished, publishable book, not just a set of pictures. You create a character once, from a description, a photo or your own art, and it stays the same on every page while you change its pose, expression, outfit, camera angle or background. Then you lay out pages with text and speech bubbles and export a 300 DPI print-ready PDF with trim, bleed and a cover wrap sized for Amazon KDP, or share the book as a flipbook or a narrated video. Most AI image tools stop at the image. Neolemon covers everything between the first character and the file KDP accepts.
Neolemon began as Consistent Character GPT, a custom GPT inside ChatGPT that went viral and reached 1 million uses. Its users kept asking for the same things: more control over each image, more convenience, more accurate characters from page to page, and above all an easy way to turn those story ideas into a finished children’s book. So husband-and-wife founders Sachin Kamath and Diana Zdybel built a dedicated platform, first as ConsistentCharacter.ai and now as Neolemon. Today it covers the whole journey: create a character, keep it consistent across every scene, lay out the pages, and export a print-ready book for Amazon KDP or share it as a flipbook or narrated video. Neolemon is bootstrapped, profitable and built from Portugal. More than 23,000 storytellers use it, working toward a mission of one million stories that spark curiosity and build empathy.
