Rev.com is how I keep up on current events, as I don't have much time to scroll through social media. At Rev.com, you truly make your own hours, and I love that flexibility. It's a great side job, or if you really can pump those keys away it can be a great main source for income as well, but that requires a lot of dedication and a good typing speed. I wish it paid a bit more, but it works for me perfectly since I have a full-time working significant other. We make it work.
A lot of the available work is very difficult audio, which decreases your words per minute drastically, resulting in pretty low hourly rate. Also, I've had projects graded improperly. The corrections made to my project were far worse than my errors. It was eventually corrected, but I had to go through several people with my complaints.
Rev is a fun and freeing company to work for. Once you pass a short assessment of your skills with speaking and writing English, grammar, punctuation, listening comprehension, etc, you're able to finish the learning process with Rev's captioning software and begin claiming captioning work.
