StudyInk - my lecture slides, rewritten as a study book by Gemma on my laptop

Описание и применение

StudyInk преобразует презентации лекций в структурированные, сканируемые заметки, используя Gemma 4 на локальном ноутбуке, без облачных платежей.

Задача

Students need concise, scan‑ready study notes from large lecture slide decks, but slides are designed for presentation, not revision.

Результат

StudyInk transforms lecture decks into a structured, scan‑ready study book on the student’s laptop, eliminating cloud costs and providing instant slide references.

Рабочий процесс

• Drop a .pptx or .pdf deck into StudyInk
• LibreOffice headless converts .pptx to PDF
• PyMuPDF extracts slide text, speaker notes, and a small picture of each slide
• StudyInk identifies figures by detecting images and vector shape clusters
• Gemma 4 (E4B) classifies each figure crop (diagram, flowchart, table, chart, screenshot, or decorative) and extracts text if needed
• Gemma 4 writes concise notes: gist, short points, step flows, comparison tables, captions, index cards, sticky notes, and self‑check questions
• Each point is footnoted with the source slide number; clicking opens the original slide
• The notebook is stored in IndexedDB; the uploaded deck is deleted from temp storage
• StudyInk runs as a native Mac app with a bundled Node runtime; it starts Ollama if needed and unloads the model on exit

Доказательства

Drop in a lecture deck (.pptx or .pdf) and it becomes a chapter of a study book

Источник

Gemma looks at every figure. This is the vision half of Gemma 4. For each crop it decides: diagram, flowchart, table, chart or screenshot (keep it, and caption it)

Источник

Every point has a footnote. Gemma tags each point with the slide it came from ([s12]), and the book turns that into a numbered footnote. Click one and the actual slide opens
