Hang in there. I've yet so see an even modestly successful business that didn't have this or some other bleak problem at one point in time. I'm sure they exist, I just haven't seen one yet :D
My gut says this one can be turned around. Even if 90% of people just happily prefer ChatGPT for this (which I'd doubt), the remaining 10% is still a lot to fund a small venture very well. Just gotta find them effectively.
Even the "giving up" route can be pretty juicy, there's companies that pay decent money for a "distressed asset". And there's also investment firms (like mine) that go for a minority stake and help turn things around.
