Why do people find the need to market as "free alternative to xyz" when its a basic utility? I take it as an instant signal that the dev is a copycat and mostly interested in getting stars and eyeballs rather than making a genuinely useful high quality product.
Just use handy: https://github.com/cjpais/Handy
Really good to know Handy exists; it's the first I'm hearing about it. I use a speech-to-text app that I built for myself, and I know at least one co-worker pays $10 a month for (I think) Wispr. I think it's possible there was no intention to market, and the creator simply didn't know about Handy, just like me.
