This product does provide a bit more of a structured approach without any of the self-hosting/coding difficulty which I think would have a wider market appeal.

Typically I'm not the one to suggest this on hobby projects being made into a product bc you gotta make money somehow to support this and I respect that to some appreciable degree.

Personally, AI for writing is in the same corner as the other pathologies you've listed (popularity counts etc), so it's not for me. But some folks will see that differently.

Other than that, I really like it. I hope this becomes a trend, and stays this way.

Personally this kind of thing is just always gonna be self hosted or local only, but I see the appeal for folks who don't have that option

Brief off-topic greybeard cloud yell: I hate that we've all adopted the colloquial use of "algorithm".

Although it's interesting to imagine whether software is even possible with "no algorithm" :)
