Need help on this wording Comparision / usage website

[aarvindravichandran]

Hi, I’m trying to develop this new site, the concept is whenever someone types any words in the “Bullet Point - 1” text box, it should compare each word with the left top text box and it should print the output in the left bottom text box, like how many times the words used and if the words used in any of the Bullet Point boxes the word should strike through and show the count of use. Like exactly in the image. I’m new to coding, hope someone will help.
