Overview

Live on-device captions for the lecture tab, with your notes, screenshots, and AI answers in one side panel.

SideNote is a study notebook for online lectures. Captions, notes, and screenshots all live in one panel next to the video. โ–  Live captions SideNote listens to the tab you are watching and turns it into captions. Start, pause, resume, and stop are all under your control. Captions stack up and follow along automatically. Scroll up to reread something and the auto-follow stops; scroll back to the bottom and it resumes. You can copy the whole transcript at once. โ–  Captions over the video Turn them on and the captions sit on top of the video, the way normal subtitles do. โ–  Screenshots with the note you took at that moment Press [Capture] and the current screen is saved. If a video is playing, SideNote crops the shot to the video area and records the playback position (12:34, say). Every capture can carry its own note, so "what I thought about this slide" stays attached to the slide. A general note for the whole lecture is saved automatically as you type. โ–  Ask the AI Send a question and SideNote captures the screen you are looking at, then hands it to Chrome's built-in AI together with the captions you just heard. It can also summarise the whole transcript, pull out key terms, and build a study file (HTML) from everything collected so far. That AI runs inside Chrome too, so neither your question nor the screen leaves your computer. โ–  One notebook per video Move to a different video and captions restart on their own. Old captions never bleed into the new video, and the previous video's captions, notes, and captures stay in [History] where you can reopen them any time. โ–  Still there when you come back Reload the page or close and reopen the side panel and everything is still there. Return to the same lecture page and SideNote picks up that notebook again. โ–  Nothing leaves your computer Speech recognition runs through Chrome's built-in on-device recognizer, on your machine. Audio, captions, notes, and screenshots are never uploaded. No account, no sign-in, no payment, no ads. โ–  Translate the lecture as you watch Watching an English lecture but want Korean captions? Open [Caption settings] and set the caption language to Korean. What is being said is shown in that language, in the panel and on the video overlay. Pick the language that is being spoken and captions stay exactly as spoken. Translation uses Chrome's built-in translator, which runs on this computer. No API key, no per-use cost, no server. Chrome downloads the translation model for your language pair the first time you use it, and support varies by device and language pair. โ–  Choose your languages The spoken language can be English, Korean, Japanese, Chinese, Spanish, French, German, Italian, Portuguese, Russian, Hindi, Arabic, Indonesian, Vietnamese, Thai, Turkish, Dutch, Polish, or Swedish. The interface language is yours to pick in the top right of the panel โ€” English, Korean, Japanese, Simplified Chinese, or whatever your browser uses, and light or dark appearance sits in the same corner. Chrome downloads the on-device speech pack for your chosen language the first time you use it. โ–  Who it is for ยท Anyone taking notes while watching lecture recordings or MOOCs ยท Anyone who wants a text record of a lecture video that has no subtitles ยท Anyone tired of screenshots in one folder and notes in another โ–  How to use it 1) Play a lecture video. 2) Click the SideNote icon on that tab. The panel opens on the right. 3) Press [Start captions]. Allow tab audio sharing when Chrome asks. โ–  Notes ยท On the first run you may wait a moment while Chrome downloads the speech pack for your language. ยท Captions come from automatic recognition, so they are not 100% accurate. Use them as a study aid. ยท Captions cannot be made for silent tabs or chrome:// pages. ยท Translation needs Chrome's built-in translator. If your Chrome or language pair does not support it, captions still work and only the translation is skipped. ยท Chrome 139 or newer is required (on-device speech recognition arrived in that version).
