One of the best options is the Custom Story Creator, an AI-powered tool to create original graphic novels. The tool lets you create comics or anime with AI algorithms that can craft fast-paced action and dramatic dialogue. It can handle more than 92 languages, including Japanese and Korean, so you can get the right words in characters' mouths. The tool also comes with an XR Reader app for Meta Quest 2 and Pro headsets for an AR/VR experience.
Another good option is ComicsMaker.ai, an online tool that automates much of the comic creation process with AI. It's got a variety of tools, including Page Designer, Text to Image and ControlNet to turn your ideas into comic art. There are also tools like Pose Creation and Character Training for maximum realism. The service lets you download comics as PDFs or CBZs and can let you make money off them through a community gallery.
If you prefer a more straightforward tool, Dashtoon has a tool with a focus on consistency and control. It's got a character library and a range of styles, along with AI tools to turn storyboards into comics. You can publish and sell your comics through the Dashtoon Reader app, so it's good for both beginners and more experienced artists.
