Introduction – The Lecture After-Life
A single 50-minute lecture can hold more high-yield facts than an entire textbook chapter—yet most of it evaporates the moment students leave the hall. According to a 2024 EDUCAUSE survey, 71 % of undergraduates re-listen to recorded lectures, but fewer than 15 % ever translate that audio into usable study aids. “Study Buddy” closes the gap: an AI toolkit that turns any lecture recording into concise revision notes plus an interactive slide deck in under four minutes. Upload a .mp3 from Zoom, an .m4a from your phone, or even a YouTube lecture link, and walk away with searchable notes and bite-sized slides you can annotate, share, or cram from on the bus ride to the exam.
Core Pipeline – From Audio to A+ in Four Moves
1.Whisper-Grade Transcription
A multilingual speech-to-text engine trained on 50 accents and 28 academic domains delivers 97 % word accuracy—even over chalk-and-talk audio.
2.Summarization Engine
Extracts key concepts, formulas, dates, and citations while filtering out filler words (“um,” “you know,” “any questions?”).
3.Dual Output
• Revision Notes: 250-word bullet summary, APA/MLA citations, glossary of new terms.
• Slide Deck: 8–12 branded slides with charts, diagrams, and speaker notes.
4.Interactive Layer
Clickable timestamps, embedded quiz questions, and optional AR flashcards for mobile review.
Supported Inputs
• Zoom, Teams, Google Meet recordings
• iPhone Voice Memos (.m4a)
• Android Recorder (.3gp, .mp3)
• YouTube lecture URLs
• Handwritten scans + audio overlay (OCR + audio fusion)
Step-by-Step Workflow (4-Minute Cycle)
Step 1 – Upload or Link
Drag the file or paste a YouTube URL. The dashboard auto-detects duration, language, and speaker count.
Step 2 – Choose Study Mode
• Cram Notes – bullet summary only
• Slide Review – bite-sized visuals
• Spaced Repetition – Anki-ready flashcards
• Interactive Lecture – clickable slides with polls
Step 3 – Configure Brand & Style
Pick school colors or dark/light theme once. AI applies consistent fonts and alt-text.
Step 4 – Generate & Review
Typical metrics:
• 45-minute lecture → 10 slides + 200-word notes in 3 minutes 20 seconds.
• 20-minute micro-lecture → 6 slides + 150-word notes in 90 seconds.
Step 5 – Export & Sync
Download PDF, open in Google Slides, or push to Notion, OneNote, or Anki. All assets sync to your phone via the Study Buddy mobile app.
Deep-Dive: AI Features Students Rely On
Timestamped Notes
Every bullet links back to the exact second in the audio—tap to replay the explanation.
Formula & Diagram Extractor
Handwritten equations or whiteboard sketches are vectorized and dropped into slides as editable MathML or SVG.
Citation Finder
Detects references like “Smith, 2023” or “Figure 3 from the Lancet” and auto-creates footnotes in APA, MLA, or Chicago style.
Quiz Generator
AI writes 3–5 multiple-choice or fill-in-the-blank questions per slide, exportable to Kahoot, Quizlet, or H5P.
Accessibility First
• Live captions in 38 languages
• High-contrast themes for dyslexia-friendly reading
• Keyboard-only navigation and screen-reader labels
