Video Intelligence Extractor

Video Intelligence Extractor lets you save YouTube captions and turn transcripts into structured AI reports. Whether the captions were uploaded by the creator, auto-generated by YouTube's speech recognition, or auto-translated into your language, this extension grabs the transcript and can export it as subtitles or analyze it into a report. ★ KEY FEATURES • One-click subtitle download — SRT, VTT, or TXT. • All caption types — manual, auto-generated (ASR), and auto-translated tracks. • Any language — original track, or translate into any of YouTube's ~125 target languages. • AI reports — generate knowledge summaries and opportunity radar reports from the transcript. • Bring your own AI key — connect OpenAI, OpenRouter, DeepSeek, Zhipu, Kimi, or your own endpoint. • Visual HTML export — dashboard-style cards, pie/bar charts, keyword cloud, and evidence views. • Report language follows your subtitle/translation choice. • Right-click menu and remembered default format. • Localized UI — English, 中文(简/繁), 日本語, 한국어, Español, Français, Deutsch, Português, Русский. ★ HOW TO USE 1. Open any YouTube video and click "Download subtitles" below the player. 2. Pick a track, an optional translation language, and a format — then Download. 3. For an AI report: open AI settings, add your provider/model/API key, then click "Generate report". ★ PRIVACY • No accounts, no tracking, no ads, and no servers of our own. • Subtitle downloading runs entirely in your browser. • The AI report feature is optional. Only when you configure an AI provider and click "Generate report" is the transcript sent — directly from your browser to the AI endpoint you chose. We never receive it; that provider's own policy governs it. • Your API key is stored locally and cleared when the browser session ends. • Full policy: <你的隐私政策URL> ★ NOTE Not affiliated with YouTube or Google LLC.
