Best Chrome Extensions for Students
A student browser has three jobs: stay on task, capture what you read, and get through long material fast. Three or four extensions cover all of it; more than that becomes its own distraction.
How we picked
- • Free or student-priced

What to know before choosing
Start with focus. A blocker that makes leaving a study session slightly inconvenient is more effective than one that is impossible to bypass, because the goal is interrupting autopilot rather than building a prison. Pair it with a highlighting and note tool so reading produces something reusable instead of a browser history you will never revisit.
For citations, a reference-manager connector is non-negotiable once you are writing anything assessed: capturing metadata at the moment you find a source saves hours of reconstructing bibliographies later. Finally, a lecture or paper summariser is the biggest time saver on long recordings and dense PDFs — use it to triage, never as a substitute for reading what turns out to matter.
