Every student follows your lesson, in their own language.
Classroom Captions turns your speech into on-screen captions and translates them in real time, inside Google Docs, Slides, or any web page you teach from.

Captions on the board for the whole room, and on each student's own screen in the language they read.
A captioning tool that actually fits a classroom.
Built by a teacher around how lessons really run: sign in with Google, press start, and keep teaching while every student reads along.
Press start. That's the whole workflow.
Your plan, your AI Coin balance, your languages, and your live class all sit in one popup. Pick Basic Mode (included, unlimited) or AI Mode when you want sharper recognition of tricky terms like "stoichiometry", counted per minute from your coin balance.
One class code, all year long.
Post a permanent code like CHEM3 in Google Classroom or Canvas. Students save it once, pick their language, and auto-connect every time you start captions, on a phone, tablet, or Chromebook. No student accounts, ever. They can even raise a hand digitally: questions arrive on your screen translated into English.
Place it where it won't cover your work.
Each language gets its own draggable, resizable caption box. Grab one and slide it anywhere on the screen; your slides, diagrams, and demos stay fully visible while everyone keeps reading.
Size, color, and transparency, live.
Slide the text size up for the back row, pick box and font colors that fit your room, and dial in transparency so captions sit lightly over your content. A live preview shows every change as you make it, and students get their own font-size slider on their end.
A record of every class, ready for Drive or home.
Every session saves on its own. Edit out names or misheard words, push it to Google Drive as a formatted Doc, or send parents a link that shows the lesson in their language for 7 days. You can also upload a recording and get a timestamped transcript back.
Vocabulary that translates correctly
Pin your subject's terms so words like "stoichiometry" come through right every time. A chemistry list ships built in.
Co-teaching
A co-teacher or aide with their own subscription can caption into your room; each line carries the speaker's name.
Accommodation room
Open a separate room where a student runs their own captions for a read-aloud test, on their own screen.
Student response mode
Tap the people icon and the mic listens in a student's language, translating their answer back to English.
Conference mode
Flag a class as an all-day event and its room stays live for 24 hours: PD days, assemblies, parent nights.
Content filter
An optional filter checks finished captions and replaces anything flagged before students see it.
Teacher Dashboard
Sign in on the web to see your plan, classes, and usage, buy AI Coin packs, and manage billing without opening the extension.
QR join codes
Show a QR code on the board and students join by pointing a camera at it. The typed code still works too.
Session summaries
Stop captions and see the class at a glance: minutes captioned, coins used, lines delivered.
Up and running in minutes.
You install once and start talking. Students join with a code and pick a language. Room sharing is handled for you: nothing to configure, no IT tickets.
You, the teacher
Install from the Web Store and sign in with your Google account. Your 10-day free trial starts automatically.
Open any page, click once, and start teaching. Captions show up instantly.
Name your class, post the code in Google Classroom or Canvas, and you're done for the year. Students reconnect on their own every time you go live — and if a student has more than one class live at once, they just pick which room they're in.
Your students
The same one-click install from the Web Store. No account, no payment, nothing to sign up for.
Type it or scan the QR code. Their class is saved from then on, one per teacher.
Your captions appear on their screen whenever you're running them, with a font-size slider and an ask-a-question button.
One simple plan.
Everything a teacher needs for $6 a month — or $64.80 a year (save 10%). AI Coins add premium recognition and translation when you want them. Students always join free.
Teacher plan — $6/mo
Sign in with Google and try everything. Cancel anytime from Manage plan, no questions asked.
Prefer annual billing? $64.80 a year instead of $6 a month — the same plan, 10% off. Pick it when you subscribe.
Live captions, translation into 100+ languages, permanent class codes, live Q&A, transcripts, vocabulary: all included.
Nothing to set up and nothing for IT to configure. Your class code works the moment you sign in.
Save any session to Google Drive or share a 7-day link parents can read in their language.
AI Coins — pay as you go
Premium recognition that nails technical vocabulary. A 50-minute period runs about $5. Nothing to set up: just flip the switch and teach.
1 coin per AI-translated line, and 1 coin per minute of any recording you upload for a transcript.
Buy packs right from the popup, or sign in to your teacher dashboard on the web and buy them there. Coins never expire.
Out of coins mid-lesson? Captions switch to the included Basic Mode without missing a word.
