Hi opryshok,
Welcome to needgap. Problems are the first class citizen here, So title and description are limited only to the problems and how you think it can be solved if you don't already have a product.
If you have a product already, then you can promote it only in the comments of a problem, explaining how it solves the problem.
Hence the problem title, description was edited. Feel free to explain how your product solves this problem in the comments.
