If I had a penny for every time I saw an AI written text about someone emphasising being a manual labourer of X years, talking about having built an App, in a post which is clearly written by AI, which use English not being their native language as an explanation for the AI usage, I'd have two pennies, which isn't a lot, but it's weird it happened twice.
Honestly, there's more mature projects that already do all that, and I wouldn't really see a reason to switch to a possibly vibe coded project, especially if I planned to use it for anything important. Also, most alternative messengers suffer from the network effect - most people won't switch to a new messenger if they're already using another, even if that other has clear deficiencies.
Also, this whole 'I'm a woodsman that wrote a word processor' thing feels like marketing copy. This isn't shark tank, you don't need a sob story. If your app is good, and you work on it consistently, people might join you in working on it and using it.
