Still stuck on GPT-3 and DALL-E 2. Results look prehistoric compared to modern generators.
Art styles are laughably basic.
Total relic from 2020. Don't waste your time.
Plots make zero sense and images are distorted.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Enter a single story idea of up to about 300 characters and receive a complete mini-novel.
Artwork is generated alongside the text so each chapter comes with matching visuals.
Pick from styles including digital art, cinematic, fantasy, colourful water painting, and painterly Van Gogh-inspired options.
Books are short by design, making them quick to read and easy to share as gifts.
Confirm your address and the finished book is generated and sent to you as a readable web page.
InstaNovel AI takes a very small input — up to roughly 300 characters of story prompt — and expands it into a compact illustrated book of four to six chapters. The service pairs a large language model for the prose with an image model for the artwork, so the text and the pictures are generated together as one package. You choose from a set of visual styles such as digital art, cinematic, fantasy, colourful water painting, or a Van Gogh-inspired look.
Delivery is deliberately simple. After you submit a prompt and confirm your email, the mini-novel is written and sent to that address, and it is rendered as a small mini-website you can read in the browser rather than a downloadable file. The stated use cases are inspiration, entertainment, language practice, and quirky personalised gifts such as a birthday present built around someone's inside joke.
The product runs on a credit-based freemium model: your first book is free and no credit card is required, while additional books and faster turnaround come from premium plans. The team notes that free-tier waiting times can be long during periods of high demand. The tool is currently English-only, with more languages stated as planned, and it is built by a small independent developer.
Build a short illustrated story around a friend's name or an inside joke for a birthday or celebration.
Turn a stray premise into a finished short story to see whether the concept has legs.
Use simple, short illustrated English stories as approachable reading material.
Generate a mini-novel just for entertainment and share the result with friends.
