iPhone voice memos sorted
I record everything on my phone in M4A. Profi PDF just eats them up and spits out perfect text. Saves me hours of re-listening.

Great for interviews
The speaker separation is legit. I threw in a messy 3-person interview and it actually figured out who was who.

Fast and cheap
Compared to hiring a human transcriber, this is a no-brainer. 99% accuracy for a fraction of the cost and time.
