Thanks for the answer!
The script is for this website:
https://gartic.com.br/It's a brazilian guessing game.
The room have a theme, and i have all names from this theme. When the player is drawing, he can give a tip in the screen to make easy. So, my script get this tip and search for similar names for me.
I don't think the website have a function for detect this. But, is possible to them get print of my screen, so i put a show/hide function on a original button of the website, to show the script only when i need it.
Thank you!
Here is a print:
