Here's what has worked for me on day 0:

What problem does your tool solve? Write a blog on "how to solve/do XYZ".

Share an easy and free way to solve the problem without using your tool. Then introduce your tool and share its advantages and drawbacks. Be genuine and honest, don't oversell it. Acknowledge alternative tools and solutions.
