Airchat seems really promising! Fun to test it today. The concept is based on voice messages, but not like Clubhouse. Far from it, actually.
The posts are actually spoken into as an audio message. Then, the audio message is converted to text. To consume content, you can either read or listen through the feed.
I love it. It's a bit unusual to speak messages among people, but at the same time, I just think of it as a kind of phone call.
