I just needed a short radio recording transcribed and went to Otter.ai but it wanted me to subscribe again, I had the pro subscription in the past and it wanted me upgrade. They do have a free service limited to 30 minutes. However, I really don't want to be mucked about, I just need an easy to access transcription service and with a one time payment this did a very fast and accurate job. For the price I cannot complain! The summary and the mind map feature is both interesting and useful too.
