Translation module

Guys, please help me solve a problem. There is a module or plugin—I don't remember exactly—but the essence is that it allows you to translate or change words on a Drupal website page. I clearly remember that after installing it, an icon appears at the bottom right of the screen, and when you click on it, a table pops up showing all the words on the page, where you can edit them. Please help if anyone knows this plugin or module. Thank you in advance!
