Might be related to https://github.com/storytold/artcraft, they posted it a while ago. I can imagine there's demand for quick storyboarding in the filmmaking / content creation world.
That said, turning a tool into a profitable business is another story entirely; if one person can turn an idea into working software with the help of AI, dozens more can too. So I'm also curious, not just from idea to software, but from software to business and millions of income.
People have gone down this road of selling niche tools many times in the past in film making. There are a lot of pitfalls.
For starters not many people need story boarding.
When someone is actually doing a project that is big enough to need story boarding, they are going to have some infrastructure and making a wrapper around prompting image generation is not going to be far fetched.
The narrow window of productions that are doing story boarding but think they need a tool to wrap image generation and have no one to script some tools themselves is pretty small.
Elaborate? Legitimately curious
