Lecture Notes Summarizer

WHAT IT DOES

Lecture Notes Summarizer extracts lecture notes, class slides, and educational content from any page and uses advanced AI to generate a structured summary with key concepts, definitions, important dates, and a study guide organized for easy review and exam preparation. It identifies the most important information from your notes and presents it in a clear, scannable format that makes studying more efficient.

WHERE IT RUNS

This tool operates as a userscript within the BotGentz extension framework, running directly in your browser on any website. It works on lecture notes, class slides, course materials, educational websites, and virtually any academic content. The tool integrates seamlessly into your workflow, appearing as a draggable panel that stays accessible as you study and prepare.

HOW TO USE

Click "Scan Page" to automatically extract the lecture content from the current page. The tool intelligently identifies key concepts, definitions, and important information. Configure your summary settings: choose your preferred summary depth (Brief, Standard, or Detailed), toggle key definitions and terminology inclusion on or off, and toggle study guide format with review questions on or off. Click "Summarize Lecture" to send the content to the AI backend. Within moments, you'll receive a structured summary of the lecture. Use the "Copy Summary" button to save it for studying.

TECHNICAL OPERATION

Lecture Notes Summarizer employs a multi-strategy extraction pipeline that first checks for selected text, then attempts WebMCP (navigator.modelContext) when available—a W3C proposal for structured page content access—and falls back to DOM-based content detection using prioritized selectors for lecture containers, educational sections, and content areas. The user's depth preference, definition inclusion, and study guide formatting settings are encoded as system-level instructions in the prompt sent to the AI. The text is truncated to 8000 characters and transmitted via GM_xmlhttpRequest to the AI backend. The AI, specifically prompted as an educational content summarization specialist, analyzes the content to identify: main topics and their hierarchy, key concepts and their relationships, important definitions, supporting examples, dates and chronological information, and recurring themes. It then organizes this information into a structured format with proper hierarchy, includes key terms with definitions when enabled, and generates review questions that test comprehension of the main concepts. Each request is authenticated with a subscription key and counts against your monthly usage cap.

THE PANEL

The Lecture Notes Summarizer panel is fully draggable and remembers its position between sessions using GM_setValue. It snaps to the edge of the viewport for a clean interface and can be collapsed to a small icon when not in use. The panel is resizable to accommodate longer content. Press Escape to quickly close or collapse the panel. The design is optimized for productivity with a dark theme, clear visual hierarchy, and responsive controls that adapt to your workflow.

PLEASE NOTE

This tool requires the free BotGentz extension installed in your browser and an active subscription to access the AI backend. AI-generated lecture summaries are intended as study aids and should be reviewed for accuracy against the original content. The tool may not capture all details, nuances, or examples from the original lecture. Always verify critical information from your course materials. No page data is stored or transmitted beyond the content you explicitly submit for summarization. All processing occurs through secure HTTPS connections, and your subscription key is never exposed to the page context.
