# Chrome Web Store listing — Live Classroom Captions (v2.23.1) ## Short summary (132-char field) Live captions with translation, plus draw and annotate on Docs, Slides, Word, PowerPoint, Canva, and any webpage. For teachers. ## Full description Live Classroom Captions turns your speech into live captions and translates them in real time, so every student can follow your lesson in a language they understand. What your students get: Choose the languages your class needs and translated captions appear on screen as you teach, so a student who reads Spanish, Vietnamese, Tagalog, Khmer, or one of 130+ other languages can follow along instead of falling behind. Your own teaching language counts as a language too, so you can run captions in English alone — what a Deaf or hard-of-hearing student needs — without translating anything. Turn on Room Sharing (a one-time setup) and students also see your captions on their own phones, tablets, or Chromebooks, each in the language they pick. You share one join code, post it in Google Classroom or Canvas, and each student pastes it into the extension once and stays connected all year. A student with several teachers keeps a saved class list and taps to switch between them. Captions appear on a student's device only after they tap Start for your class, and stop when you stop presenting. Students can also send you a question right from their caption view, without raising a hand. What you do as the teacher: Start captions from the toolbar and a caption overlay appears on whatever tab you're presenting, whether that's a Google Doc, a slideshow, a video, or a simulation. Your words appear in English as you speak, with each translation beside them in its own color-coded box. Drag the boxes, resize them, and style them so they sit where they won't cover your content. The captions keep running as you move between tabs. Student questions collect in a movable panel on your screen, so you can answer them when it fits your lesson. Draw and annotate on anything: Mark up your lesson right on top of a Google Doc, a Google Slides deck, a Word document, a PowerPoint deck, a Canva presentation, or any webpage. Ink anchors to the content, so your notes stay put while you scroll a document or move through slides. * Tested and confirmed on Google Docs, Google Slides, Microsoft Word on the web, Microsoft PowerPoint on the web, Canva presentations, and ordinary web pages — including full-screen presenting in Slides, PowerPoint, and Canva. * Pen, highlighter, and a precise eraser. On a touch screen, wipe with your palm like a real whiteboard. * Sketch a rough line, circle, square, or triangle and it snaps into a clean shape. Triangles come out as the kind you drew: right, isosceles, or equilateral. * Insert shapes, a Cartesian graph with adjustable increments, a ruler, and a protractor. Resize, recolor, fill, group, lock, and layer them. * Arrows have a handle at each end: drag either one to swing the arrow around and stretch it in a single motion, and put a head on one end or both — the second head gives you an equilibrium arrow. * Whiteboard mode gives you a blank surface to write on, with your caption boxes still visible on top. * Presenting in Google Slides, PowerPoint, or Canva? Keep drawing in fullscreen. Change slides with your keyboard, a presenter remote, or the pen toolbar's own arrows without leaving Draw mode — and each slide keeps its own ink. More for real classrooms: * Student response mode: tap the people icon and the mic listens in a student's language, then translates their answer back to English so the whole class can follow. * Accommodation room: open a separate room where a student runs their own captions for a read-aloud test, independent of your main session. * Custom vocabulary: add the terms your subject uses so they translate correctly every time. Some subject specific vocabulary packs are already offered for free! More can be added upon request. * Your choice of recognition: use the free built-in speech recognition, or connect an OpenAI API key for higher accuracy with technical terms - this is a cost to you. Transcripts: Every session saves automatically as a transcript you can edit. Connect Google Drive and each session also saves as a formatted Google Doc with a single click to authorize, no setup required. The extension can only see the files it creates; it never touches the rest of your Drive. Privacy: Audio is processed in your browser by Chrome's built-in speech recognition. This extension never records, uploads, or transmits your audio. Only the resulting text is used. See the privacy policy for details. Try it free: Every feature is unlocked for 10 days. No ads, ever.
