YouTube Transcription, Summary & Fact Check

BYOK YouTube auditor: transcribe, summarize & fact-check videos in multiple languages using your own Gemini API key.

With the explosion of AI-generated content, YouTube is now flooded with videos that spread misinformation, inaccurate data, and unverified claims. It has become increasingly difficult for viewers to distinguish fact from fiction. This extension is designed to restore trust in your video-watching experience through three powerful, sequential core features: 1. Transcribe (Dual-Path Extraction) Get highly accurate text layouts from any video. The extension automatically detects and grabs the existing YouTube captions. If no captions are available, it seamlessly leverages Gemini to perform advanced AI-powered transcription. Works on any non-membership YouTube video — lectures, news segments, documentaries, commentary, and Shorts. 2. Summarize (Argument Dissection) Don't waste time on fluff. This feature dissects the generated transcript, instantly extracting the core arguments, main points, and essential takeaways to give you a clear, concise summary. 3. Audit (Fact-Checking & Verification) Take your research to the next level. The AI goes deep into every extracted argument, conducting real-time web searches to cross-reference and verify the claims. It then compiles the results into a comprehensive Audit Report embedding an Evidence Table with cited sources, letting you assess the video's accuracy and the channel's overall credibility at a glance. ⚡ Smart Efficiency & Cost Optimization Built for power users who demand maximum performance with minimal API expenses, the extension includes advanced budget and data management tools: • Support YouTube Shorts & No-caption Videos: Leverage Gemini's multimodal video analysis to generate transcripts for videos without official captions and YouTube Shorts, with high accuracy. • Cross-Device Syncing & Merging: Access your research anywhere. Seamlessly sync and merge your transcripts, summaries, and fact-check reports across multiple devices. • Persistent History (Token Saver): Never pay for the same video twice. The extension securely stores your past analyses in a complete history log, letting you re-read reports instantly without re-querying the AI or wasting tokens. • Multi-Model Routing: Drastically slash your token expenses. You can assign different AI models to different tasks—for example, utilizing a fast, low-cost model for transcription, while reserving a heavy-duty model for deep fact-checking. • Token Tracker & Cost Predictor: Keep full visibility over your budget. The built-in dashboard automatically monitors your token usage in real-time and predicts estimated costs before running a task. • Multi-Lingual Support: Available in 10 languages: English, Traditional & Simplified Chinese, Japanese, Korean, French, Spanish, Portuguese, German, and Russian. • 5-Metric Channel Credibility Matrix: Automatically track and log the reputation (weighted scoring of claims' Occurrence, Completeness, Precision, Attribution, Objectivity) of your frequently visited channels. The extension scores and records channel reliability based on a specialized 5-scoring matrix over time. 🔒 Privacy First: Bring Your Own Key (BYOK) We prioritize your data privacy above all else. This extension operates on a strict "Bring Your Own Key" model: • BYOK: Use your own API key from Google or other official providers for AI transcription, AI summary, and AI fact check (audit). Basic caption extraction works without one. No subscription fee and unlimited usage. • No Intermediate Servers: Your API keys and data are stored locally in your browser's secure storage. All AI requests are sent directly to the official providers such as Google. We never middleman, collect, or store your keys or prompts. • Direct Verification: Your web search and fact-checking workflows happen entirely between your browser and the AI ecosystem, ensuring absolute confidentiality for your research. Stop watching blind. Don't let AI-generated misinformation mislead you. Take control of the facts and ensure what you learn is accurate. Every video you audit makes your feed smarter and your judgment sharper.
