(Don't forget to comment on my online class idea.)
I just found this great resource called AutoCrit. It analyzes your writing to catch words and phrases repeated and overused in your manuscript.
From the contest judging and freelance editing jobs I have done, I know that other writers as well as myself have a tendency to repeat words and/or phrases, not just our “hot words.”
For example, “pop” is not a word I use often, but I might write something like:
I went to the local mom and pop grocery to grab a soda pop, and then I popped out of town.
The free version is very limited and will only catch overused words, repeated phrases, and sentence variation. You can also only submit 800 words 5 times in one day.
The paid versions offer more, included repeated words (which would catch the “pop” above), dialogue tags, first words, and names and pronouns.
The free version itself is amazing. The cost for the lowest level of membership isn’t bad, just $20 for one year, and it analyzes the things that I have the most problems with—pronouns, repeated words, and first words.
Check it out for yourself. Even just using the free version once a day will help you with your writing.
(disclaimer: I don't get any cutbacks or kudos from Autocrit, I just think it's a great resource.)
