Most schoolwork now happens in a browser, from essays in Google Docs to research across dozens of tabs. The extensions below target the parts of that workflow that go wrong most often: sloppy grammar, too many open tabs, distracting sites during study time, and long readings that are easier to listen to than read.
Writing and grammar checkers
Grammarly checks spelling, grammar and tone as you type across Google Docs, Gmail and most websites, and its free tier catches the majority of common mistakes. LanguageTool is a strong alternative, especially for students writing in languages other than English, since it supports grammar checking in more than twenty languages.
Staying focused during study time
BlockSite blocks distracting websites and can schedule focus periods so social media and games aren't reachable during study hours. StayFocusd limits how much time you can spend on chosen sites per day, then blocks them once your allowance runs out, which suits students who don't want a site blocked entirely, just limited.
Managing tabs and reading material
OneTab collapses every open tab into a single list with one click, freeing up memory and reducing the visual clutter of research spread across dozens of tabs. Read Aloud converts any web page or PDF into speech, useful for reviewing long readings while doing something else, or for students who retain information better by listening.
