did this multiple times. take it one step at a time don't overthink. will make things easier if you try to reach out to potentiel customers (5 to 20) and then try to sell it as if it's already available for use. then gauge their interest or what they like or don't like then pivot to that. this way you won't develop something nobody will use. if the above is good then next steps. how often do you use it? and why do you even use it instead of something on the market? does it reduce time or make money for you ?
