If you want to concentrate on the story and inspiration behind your comic while letting the computer handle the art, SkyReels could be a good option. The tool uses AI algorithms to maintain consistency in character designs and backgrounds so you can concentrate on the story. It's got features like image reference mode, detail control and two-character composition, and offers a free version and several paid tiers.
Another good option is ComicsMaker.ai. This web-based tool automates much of the comic creation process with AI tools like Page Designer, Text to Image, Image to Image and ControlNet. It also has Pose Creation, Inpainting and Region Prompting for photorealism. The service lets you download comics as PDFs or CBZs, and you can use it for commercial purposes under the Creative ML OpenRAIL-M license.
If you want to try a wider range of comic styles and layouts, AI Comic Factory could be the way to go. The service, which relies on the Hugging Face Space, can generate comics with automatic consistency in characters and multiple style choices. You can also upload your own images to fine-tune your comics, and there are several pricing levels depending on your needs.
Last, Dashtoon is a relatively easy-to-use service that can turn your story into a comic. Its tools include a character library, multiple style choices and AI tools to convert storyboards, remove backgrounds and upscale images. It also has a way to publish and monetize your comics through the Dashtoon Reader app, so it's good for both experienced artists and those who are new to the medium.
