Focus for Google Docs helps you enter the writing flow by decluttering Google Docs and adding a pomodoro timer. It is great for minimalists, those who want to avoid getting distracted, and those who want to write for 20-minute blocks with 5-minute breaks in between.
Click the pomodoro timer in the bottom-right of the Google Doc to enter focus or start a pomodoro session.
Click the extension icon to modify the settings.
Note: Chrome version of at least 102 is required. If you have Chrome version 94 or earlier, you will have to upgrade Chrome for Focus for Google Docs to work.
