EchoX - Transcribe and Summarize YouTube & Vimeo

About

Streamline your research with EchoX: Transcribe, summarize, and chat with YouTube & Vimeo videos or local TXT/PDF documents directly in your browser using your own AI keys.

EchoX is the ultimate intelligence companion for researchers, marketers, and smart people. Extract transcripts from YouTube and Vimeo in seconds, upload your own local files, generate insightful summaries, and ask specific questions about the content using your own OpenAI or Google Gemini API keys – fast, cost-effective, and privacy-focused. Available in English & German.

🚀 Key Features:

1️⃣ Universal Extraction & File Uploads
• Multi-Platform Support: Works seamlessly on both YouTube and Vimeo. Automatically detects available captions/subtitles.
• Local File Support: Bring your own documents into the mix! Upload .txt or .pdf files to summarize them alongside your videos.
• Instant Export: Copy or download the full transcript as a clean text file (.txt) with a single click.
• MetaData & Timestamps: Optionally include video title, channel name, publication date, description, and exact video timestamps in your text. In your generated summaries, these timestamps automatically turn into clickable deep links, jumping straight to the exact moment in the video for perfect referencing.

2️⃣ AI-Powered Summarization & Chat (BYOK)
• Tailored Summaries: Generate deep insights exactly how you need them. The AI creates structured documents based on the exact instructions of your selected prompt.
• Iterative Refinement & Versioning: Not completely satisfied? Instruct the AI to refine its previous output (e.g., 'Make it shorter' or 'Focus more on aspect X'). EchoX stores your session's generation history in an elegant accordion view, so you can seamlessly iterate without ever losing previous versions.
• Interactive Q&A: Have a quick follow-up question? Use the integrated chat to converse directly with the video transcript or document and get instant, context-aware answers.
• Bring Your Own Key: Connect your personal OpenAI ChatGPT or Google Gemini API keys. You pay only for what you use, directly to the provider.
• Model Flexibility: Switch between cost-efficient models for quick overviews or high-intelligence models for deep analysis.
• Smart Chunking: Automatically handles long texts by splitting them into logical chunks. A smart alert warns you if token limits are exceeded during batch processing, allowing you to seamlessly increase the limit on the fly.
• Rich Export: Copy your generated insights, download them as a .txt file, or export them perfectly formatted to MS Word.

3️⃣ Customizable System Prompts
• Built-In Templates: Don't settle for generic outputs. Use our carefully crafted defaults like "Deep Dive Summary", "Pre-Watch Check", "Step-by-Step Guide", "Fact Check" or "Simple Summary".
• Create Your Own: Define custom prompts with dynamic placeholders like {{title}}, {{author}}, {{date}}, and {{url}} to match your specific workflow.
• Import/Export: Share your best prompt engineering setups with colleagues via simple text file (.txt) import/export.

4️⃣ Batch Analysis & Flexible Workspace
• Playlist Workflow: Process multiple videos and documents in a queue.
• Combined Mode: Merge the insights of multiple sources into one single summary document – perfect for researching a topic across several videos and PDFs.
• Dark Mode: Toggle the beautiful dark theme for late-night research or to perfectly match your OS setup.
• Full-Screen Tab Mode: Work quickly in the compact extension popup, or expand EchoX into a dedicated browser tab for a distraction-free reading and chatting experience.

🔒 Privacy First: Your data stays yours.
• Client-Side Only: EchoX operates locally in your browser. Uploaded PDFs are parsed securely on your device using Mozilla's open-source PDF.js—never sent to external servers.
• No Middleman: Your API keys are strictly stored in your device's secure local storage (chrome.storage.local) and are sent directly to OpenAI or Google only for processing.
• No Tracking: We do not track your browsing history, analyze your content consumption, or send transcripts to our servers.
