I use Blip basically every day. And there were some hiccups where I really felt that I'm missing this easy way to just speak my thoughts. The founder went with me on a call and helped me fix the issue. And in the end it was a backend-domain that my company network was blocking, which we had to whitelist.
So far I've had a good experience with Blip. Not all translations are always correct from the beginning, but this is to expected. It's still way faster to just speak than to type every single word.
