Generating leads / users for image to word / text conversion website (AI tool)

I'm trying to try out the website / project that I made, that allows users to convert Images / photos / pdf's to Word and text documents.
The job is to try and engage in conversations on Facebook, Reddit, and other platforms to try and get people to use the website - It's free for now so should be pretty easy, I'm trying to get some people to incorporate it into their daily toolbox
