Brainstorming Session: YouTube Subtitle Extraction & AI Summarization Bookmarklet
Session Date: September 5, 2025 Topic: YouTube subtitle extraction and AI summarization bookmarklet for Android Chrome Participant: User Facilitator: Mary (Business Analyst)
Executive Summary
Session Goals:
- Broad exploration initially to discover creative possibilities
- Focus on technical feasibility and user experience
- Target audience: Mobile users watching educational YouTube content
- Technical constraints: Android Chrome, JavaScript bookmarklet, no special permissions
Phase 1: Broad Exploration - What If Scenarios
Core Vision Clarified
- Primary Function: AI summary of YouTube auto-generated subtitles using Claude.ai subscription
- User Journey: Visit youtube.com video → activate bookmarklet → get AI summary
- Output Format: New page with structured summary
User Requirements Identified
Summary Structure Desired:
- Overview - Video explanation for beginners
- Essential Points - Key takeaways
- Value Proposition - Why watch this video
- Beginner Summary - Accessible explanation of the topic
- Sharing Capability - Share the generated summary
Phase 2: User Experience Journey Mapping
User Journey Flow
- Activation Moment: Any time during video viewing (typically after pausing)
- Processing Time: User willing to wait for Claude.ai processing time
- Page Structure: New page opens with summary, original video remains accessible
- Sharing Options:
- WhatsApp: WhatsApp-formatted text
- Email: HTML format
- Clipboard: HTML format
Detailed User Flow
- User watches educational YouTube video on Android Chrome
- User pauses video when ready for summary
- User activates bookmarklet
- New page opens with Claude.ai processing
- User receives structured summary in new page
- Video remains accessible in original tab
- Multiple sharing format options available
Phase 3: Technical Constraint Exploration - Creative Solutions
Technical Solutions Identified
1. Subtitle Extraction Strategy:
- Inspiration from https://www.downloadyoutubesubtitles.com
- Bookmarklet functionality to download auto-generated YouTube subtitles
- Extract subtitle data directly without requiring special permissions
2. Claude.ai Integration (RPA Approach):
- JavaScript automation to simulate human interaction
- Automatically input extracted subtitle text into Claude.ai textbox
- Programmatically trigger chat button click
- Mimics human workflow for seamless integration
3. Mobile Formatting Requirements:
- Readable, spaced layout for mobile consumption
- Easy-to-follow structure
- Clean, uncluttered presentation
- Optimized for Android Chrome viewing
4. Sharing Implementation:
- Clipboard integration for manual paste functionality
- User can paste content into any desired platform
- Maintains formatting flexibility across different sharing contexts
Phase 4: Convergence & Prioritization - Solution Architecture
Detailed Technical Discovery
Subtitle Extraction API Identified:
- Base URL:
https://www.downloadyoutubesubtitles.com/?u=[YouTube_URL] - Direct download endpoints discovered:
- Auto-generated English:
https://www.downloadyoutubesubtitles.com/get2.php?i=VIDEO_ID&format=txt&hl=a.en&a= - Manual English:
https://www.downloadyoutubesubtitles.com/get2.php?i=VIDEO_ID&format=txt&hl=en&a=
- Auto-generated English:
- Challenge: CAPTCHA verification for human users
- Solution: User intervention for CAPTCHA when needed
Prioritized Solution Architecture
Selected Component Combination:
- A1: Leverage downloadyoutubesubtitles.com API with CAPTCHA handling
- B1 (Primary): RPA automation (fill textbox + click) in Claude.ai
- B2 (Fallback): Manual paste if RPA fails
- C2: Output displayed in Claude.ai tab with results
Implementation Strategy
- Extract YouTube video ID from current page
- Call subtitle API with user CAPTCHA intervention if needed
- Open Claude.ai in new tab
- Attempt RPA automation to input text and generate summary
- If RPA fails, provide clipboard copy for manual paste
- Display structured summary in Claude.ai interface
Idea Categorization
Immediate Opportunities (Ready to implement)
- Basic bookmarklet creation - Extract video ID and create subtitle API calls
- CAPTCHA handling workflow - Guide user through manual intervention when needed
- Claude.ai tab opening - Simple window.open() to claude.ai with new chat
- Clipboard fallback - Copy formatted text when RPA automation fails
Future Innovations (Requires development/research)
- Advanced RPA automation - Sophisticated Claude.ai interface manipulation
- Multi-language support - Extend beyond English subtitles
- Batch processing - Handle multiple videos in sequence
- Custom prompt templates - Different summary styles for different content types
Moonshots (Ambitious concepts)
- CAPTCHA bypass techniques - Automated CAPTCHA solving
- Direct Claude.ai API integration - Official API instead of RPA
- Browser extension evolution - Full-featured extension vs bookmarklet
- Cross-platform compatibility - iOS Safari, desktop browsers
Action Planning
Top 3 Priority Ideas
-
MVP Bookmarklet (Priority 1)
- Rationale: Core functionality with manual fallbacks
- Next steps: Code basic video ID extraction and API calls
- Resources needed: JavaScript development, API testing
- Timeline: 1-2 weeks for working prototype
-
RPA Automation for Claude.ai (Priority 2)
- Rationale: Key differentiator for seamless experience
- Next steps: Research Claude.ai DOM structure, test automation
- Resources needed: Advanced JavaScript, DOM manipulation
- Timeline: 2-3 weeks after MVP
-
Enhanced User Experience (Priority 3)
- Rationale: Mobile optimization and sharing features
- Next steps: Design mobile-friendly interface, implement sharing
- Resources needed: UI/UX design, mobile testing
- Timeline: 1-2 weeks after core functionality
Reflection & Follow-up
