(Don't take what follows as a judgement of your product. i haven't tried it and it may be amazing!)

What you are struggling with is simply a fact of life for any entrepreneur.

Get an idea, work on it, launch and discover if there is a market fit. IF no, move to next idea, start process over. Almost every great business has examples of pivoting from the original product or service and trying other ideas until landing on the one that hits.

You've built a tool. call it a your "prototype". first test case is you. do you like using it? does it truly make your life easier and more productive? IF your answer is meh, then put it aside and move on to other things.

It's depressing to leave an idea for dead. It's your baby and you love it, but it may just not be that idea's time, you may be able to come back to it at a later date with new eyes and find a way. Regardless, the journey of building something is of value to you - you can't help but learn from the experience and apply those lessons to the next endeavor.

Also, I'll state the obvious here... Building a tool for the market and building a company to sell it are two very VERY different things.

The fact that you hit the wall when it came time to take your product to market might be an indicator for you. Maybe your are Woz and you just need to find your Steve.

If this try is a failure, continue to believe in yourself and never give up.

So many successful entrepreneurs are serial failures, until they aren't.
