Best Chrome Extensions for Teachers and Educators

Modern teaching increasingly happens through a browser — Google Classroom, learning management systems, video conferencing, and digital content creation tools all live online. The right Chrome extensions for teachers reduce administrative friction, improve student engagement, and make the technical side of teaching invisible so you can focus on the work that matters. Here are the top extensions for educators in 2026.

1. Screencastify — Create Video Lessons

Screencastify is the most widely used screen recorder in education. It integrates directly with Google Classroom and Google Drive, making it easy to record video lessons, tutorial walkthroughs, and assignment feedback. Students receive a video link in Classroom without any upload hassle on the teacher's end. The free tier is limited to 30-minute recordings, which covers most lesson needs.

2. Google Read&Write — Support All Learners

Read&Write (by Texthelp) supports students with dyslexia, learning disabilities, and English Language Learners by adding text-to-speech, picture dictionaries, and vocabulary tools to Google Docs and web content. Teachers can grant students access to the extension as an accommodation, creating a more inclusive classroom without separate technology setups. The school license makes it available across an entire class or school.

3. Pear Deck — Interactive Presentations

Pear Deck turns Google Slides presentations into interactive lessons where students respond to questions in real time on their own devices. Teachers see every student's response aggregated on their screen, making it easy to identify misconceptions quickly. The formative assessment data from each lesson is automatically saved to a spreadsheet. Pear Deck's Chrome extension integrates directly into Google Slides.

4. Kami — Annotate PDFs and Documents

Kami lets students annotate PDFs, images, and Google Docs with highlights, sticky notes, text boxes, drawings, and audio comments — all in the browser. Teachers assign documents through Google Classroom, students annotate them directly in Kami, and submissions return to Classroom with full annotation preserved. It eliminates the print-annotate-scan cycle that slows down paper-heavy assignments.

5. Mote — Voice Comments in Google Classroom

Mote adds a microphone icon to Google Classroom and Google Docs comment sidebars. Record a voice comment in seconds and it appears as a playable audio clip for the student. Voice feedback is faster to give than typed comments, more nuanced, and often more impactful — students respond better to hearing their teacher's voice than reading text notes. The free plan allows a limited number of voice comments per month.

6. Loom — Personalized Student Feedback

Loom is Mote's big sibling: instead of just audio, Loom records your screen and camera simultaneously. Record a personal feedback video for a student, showing their work on screen while you narrate your comments. Research on personalized video feedback shows significantly higher student engagement with feedback compared to written comments. The free plan allows 25 videos per month.

7. Dualless — Split Browser Into Two Windows

Teachers who use a single monitor often need to have a lesson plan, presentation, and student view visible simultaneously. Dualless splits your browser into two configurable side-by-side windows, simulating a dual-monitor setup on a single screen. Essential for virtual teaching from a laptop without external monitors.

8. Google Dictionary — Vocabulary Support

Google Dictionary shows the definition of any word in a popup when you double-click it. For content-heavy subjects where students encounter unfamiliar vocabulary, teaching students to install this extension empowers them to self-serve vocabulary lookups rather than interrupting the lesson flow for definitions.

9. Grammarly — Professional Teacher Communications

Grammarly helps teachers communicate professionally in emails to parents, colleagues, and administration. Clear, error-free writing reflects professional competence and builds trust with families. The free version is sufficient for most teachers' needs.

10. uBlock Origin — Cleaner Classroom Browsing

uBlock Origin removes ads from every website, making web-based research cleaner and safer for classroom use. Projection-based lessons benefit especially from an ad-free browsing experience that avoids potentially inappropriate ad content appearing on screen.

Conclusion

The best Chrome extensions for teachers share a common goal: reducing the technology friction between a great teaching idea and its execution. Screencastify, Pear Deck, Kami, and Mote together create a comprehensive digital teaching toolkit that works entirely within the browser.
