I was working on a TV script when I noticed that the word "look" was used a few more times than it should've been. The repeated words weren't close together, they were pages apart, so it was hard to detect his kind of word "echo".
I usually make short films or illustrated books but since I also have some programming experience, I decided to make a tool to help me detect my word patterns in screenplays in an easy and automatic way.
A long week of work later and I had a functioning version of the tool you see now.
This script tool gathers all the action, dialogue and parenthetical elements from a Final Draft® screenplay and figures out the frequency counts for all the words from these elements in your script.
Use this tool with common sense, sometimes a much-repeated word has artistic reasons for existing such as a particular character's speech patterns or whatnot.
But on the other hand, breaking out the thesaurus and varying your word usage can often yield better results and provide a more captivating reading experience.
Either way I hope you find that this tool helps you improve your screenplays.
Good luck, Scott
