Summarize the YouTube video in the current tab with Gemini, using your own API key. YouTube Quick Summary — AI Video Summaries An extension that uses Google's Gemini AI to summarize the content of Youtube videos. Summarize any public YouTube video with Gemini AI. Bring your own free API key. No account, no tracking, no data collected. Stop watching a 40-minute video to find out whether it's worth 40 minutes. YouTube Quick Summary reads any public YouTube video with Google's Gemini AI and gives you a TL;DR plus 4–8 concrete key points — usually faster than you could skim the comments. It runs entirely in your browser using your own free Gemini API key. There is no server, no account, no sign-up, and no data collection of any kind. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TWO WAYS TO SUMMARIZE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ FROM THE TOOLBAR Open a video, click the extension icon, hit Summarize. Works on regular videos, Shorts, and youtu.be links. ▸ WITHOUT OPENING THE VIDEO Click the ⋮ (three-dot) menu on any thumbnail — home page, search results, the sidebar, the watch page — and choose "Summarize". A clean panel opens over the page. Decide whether to watch before you spend the time. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • A 2–3 sentence TL;DR covering what the video is about and what it concludes • 5–8 bullet points, each one specific and information-dense • Concrete claims, numbers and names — not vague filler No captions required. Gemini watches the actual video, so videos with no subtitles work fine. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SUMMARIES ARE SAVED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every summary is cached in your browser, so you never pay to summarize the same video twice. • Open a video you've summarized before and the summary appears instantly — no API call • Browse your full history, newest first, from the popup • Search across titles and summary text to find that one video again • Delete individual summaries, or clear the lot in one click • Keeps your 100 most recent summaries automatically ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY — READ THIS PART ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This extension collects nothing. Not "anonymized" data, not "aggregate" analytics. Nothing. • No account, no login, no backend server — there is nowhere for your data to go • No analytics, no telemetry, no tracking, no ads • Your API key is stored locally in your browser and sent only to Google's Gemini API, in a request header — never in a URL, never to the developer • Your summaries are stored locally and never uploaded • Zero third-party requests. The extension makes exactly one kind of outbound call: to Google's Gemini API. It doesn't even load video thumbnails, which is why the history list is text-only by design • Fully open source — read every line before you install it The permission to access youtube.com exists for one reason: to add the "Summarize" row to YouTube's ⋮ menu and to draw the summary panel. The YouTube page never sees your API key — the key is held by the extension's background worker, in a separate context the page cannot reach. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SETUP (2 MINUTES, ONE TIME) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Go to aistudio.google.com/apikey and sign in with a Google account 2. Click "Create API key" and copy it 3. Click the YouTube Quick Summary icon, open settings, paste the key, click Save That's it. Google's free tier is enough for normal personal use. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY BRING YOUR OWN KEY? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Because the alternative is worse. A summarizer with a built-in key needs a server to hide that key behind, and a server that sees every video you summarize. That server costs money, which means a subscription, an ad, or your data as the product. BYOK removes all of it. You talk to Google directly, you see exactly what your usage costs, and there is no middleman — including the developer. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ GOOD TO KNOW ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Public videos only. Private, unlisted, age-restricted, region-blocked and members-only videos can't be read by Gemini — that's a limit on Google's side, not something an extension can work around • Google's free tier caps YouTube video input at 8 hours of video per day. Ordinary use won't come close • Long videos take longer. Gemini processes the whole thing; the request gives up after 3 minutes • Summarizing from the ⋮ menu keeps running while you browse. Summarizing from the toolbar popup does not — Chrome closes popups when they lose focus, which cancels the request. Use the ⋮ menu if you want to keep clicking around • Light and dark themes, following YouTube's theme on the page and your system setting in the popup ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ OPEN SOURCE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Source: https://github.com/adrian1715/video-summarizer No build step, no bundler, no dependencies, no minified blobs. What's in the repository is what runs in your browser — you can read all of it in an afternoon.
