On the plus side I have now the solution to my personal problem and learned a ton about building an AI based app.
Yep, I built my SaaS for exactly this reason as the top priority - to solve a problem for myself. Anything after that would simply be a bonus.
I'm building persumi.com for writing/blogging, and rizz.farm for doing lead generation on Reddit.
Built persumi's MVP in three months in my spare time, and rizz.farm in six weeks in my spare time (but haven't launched it).
I built both projects out of my own needs - persumi for replacing my own blog, and rizzfarm for promoting persumi, hehe.
Might start a 3rd one soon (as I like to tinker) though I haven't found a problem to solve yet. :)
