I built Nitpicks initially because I was tired of PMs sending me small screen recordings with changes they wanted, so that it automatically implemented them for me.
Then, I was very surprised by the good results that it was producing so I decided to convert it into an actual product others can use. It is really useful for non-technical people in a product team. The whole team can now contribute to the product even if they have no idea of how to code, it's just a click and record the screen.
I would love to see you trying it out and sharing your feedback. Feel free to reach out directly to the email at the footer of the page.
