You should be using voice-to-text. I use Wispr Flow. That is my enthusiastic recommendation, alongside my belief that people and tasks differ; talking is not the right interface for everything. - Source: dev.to / 26 days ago
There are some great tools out there for this, like Wispr Flow (Paid) or Handy (Free). But for now, I'm just using native dictation. - Source: dev.to / about 1 month ago
I'll use Raycast Dictation throughout this article, but the same approach works with other tools such as VoiceInk, superwhisper, or Wispr Flow. Pick whichever one suits you best! - Source: dev.to / 4 months ago
