Video Intelligence Extractor

Download YouTube subtitles and turn transcripts into AI summaries, opportunity insights, and reports.

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.
