PowerPoint and Image Flashcards: Turn Slides and Photos into Study Decks

Lecture slides pile up fast. By midterm, you've got hundreds of PowerPoints with diagrams, tables, bullet points, and visual content that standard text extraction can't handle properly. Images from textbooks, annotated diagrams, handwritten notes—visual study materials are everywhere.

MemoForge now processes both PowerPoint presentations and direct image uploads using advanced vision AI. Diagrams, tables, multi-column layouts, handwritten annotations—the AI sees what you see and extracts meaningful flashcards.

Why Visual Processing Changes Everything

Traditional OCR (text recognition) struggles with real lecture slides:

• Multi-column layouts get scrambled
• Diagrams and flowcharts lose meaning
• Tables become unreadable text blobs
• Handwritten annotations disappear

Vision AI is different. It understands spatial relationships, interprets diagrams, reads tables correctly, and preserves the connection between text and visuals.

The result: flashcards that actually capture what your slides teach.

Supported File Types

PowerPoint Presentations

Slides are converted to high-resolution images (200 DPI) before AI processing, preserving all visual elements.

Image Files

Upload up to 20 images per processing job for batch flashcard generation.

Perfect Use Cases

Medical and Science Slides

Anatomy diagrams, biochemical pathways, histology slides—visual-heavy content that loses meaning when reduced to text:

• Anatomy: Labeled diagrams become anatomical flashcards with structures, relationships, and clinical relevance
• Biochemistry: Pathway diagrams convert to step-by-step process cards
• Histology: Microscopy images become identification and characteristic cards
• Pharmacology: Mechanism of action diagrams become drug cards

Lecture Slide Decks

Professor's PowerPoints often pack more information into visual layouts than pure text extraction captures:

• Complex tables with comparison data
• Flowcharts showing decision processes
• Diagrams with labeled components
• Multi-column lists and hierarchies

Vision AI preserves these relationships in generated cards.

Textbook Diagrams and Figures

Screenshot key figures from your textbooks:

• Process diagrams with numbered steps
• Comparison tables
• Labeled anatomical or technical illustrations
• Maps, charts, and visual data

Each figure becomes multiple targeted flashcards.

Handwritten Notes and Whiteboards

Photographed whiteboard notes or handwritten study sheets:

• Formulas and equations
• Quick diagrams and sketches
• Mind maps and concept webs
• Annotated problem solutions

The AI reads handwriting (when reasonably legible) and extracts key information.

How PowerPoint Processing Works

1. Upload your .pptx or .ppt file (up to 100 MB)
2. Slides convert to high-resolution images (200 DPI for optimal quality)
3. Vision AI analyzes each slide — text, diagrams, tables, layouts
4. Structured flashcards generated — respecting visual relationships
5. Download and study — export to Anki with proper formatting

Processing time scales with slide count. A 50-slide deck typically processes in 3-5 minutes.

How Image Batch Processing Works

1. Upload multiple images (up to 20 per job, 25 MB each)
2. Vision AI processes each image — visual content understood in context
3. Flashcards generated across all images — coherent deck from multiple sources
4. Review and export — combined deck ready for study

Perfect for processing a set of textbook screenshots, anatomy atlas pages, or photographed whiteboard notes.

Tips for Best Results

Image Quality Matters

Higher quality input = higher quality output:

• Resolution: Clear, readable images (avoid heavily compressed JPEGs)
• Lighting: Even lighting without harsh shadows or glare
• Focus: Sharp focus on text and diagram elements
• Cropping: Trim unnecessary margins and background

Slide Design Considerations

Slides with clear structure process better:

• Headings: Clear slide titles help organize card topics
• Bullet points: Well-structured lists convert to discrete facts
• Diagrams: Labeled components become identifiable flashcard targets
• Tables: Properly formatted tables become comparison cards

Prompt Specificity

Guide the AI with specific learning goals:

❌ "Make flashcards from these slides"

✅ "Create anatomy flashcards from these slides. For each labeled structure, include: name, location, function, and clinical significance. Use the diagram relationships to create 'what connects X to Y' cards."

✅ "Generate pharmacology flashcards. Focus on: drug class, mechanism of action, indications, and side effects mentioned. Create comparison cards for drugs in the same class."

Batch Images Thoughtfully

When uploading multiple images:

• Group related images (same topic/chapter)
• Include context images (introductory slides with definitions)
• Order matters less than content coherence
• Don't mix unrelated topics in one batch

Content Examples

From an Anatomy Slide

Input: Labeled diagram of the heart chambers

Generated Cards:

• "What are the four chambers of the heart?" → "Right atrium, right ventricle, left atrium, left ventricle"
• "Which chamber receives deoxygenated blood from the body?" → "Right atrium (via superior and inferior vena cava)"
• "What separates the right and left ventricles?" → "Interventricular septum"

From a Comparison Table

Input: Slide comparing Type 1 vs Type 2 diabetes

Generated Cards:

• "Onset age: Type 1 vs Type 2 diabetes" → "Type 1: Usually childhood/adolescence. Type 2: Usually adulthood (increasingly younger)"
• "Insulin production: Type 1 vs Type 2" → "Type 1: Little to none (autoimmune destruction). Type 2: Normal or elevated initially, declining over time"

From a Process Flowchart

Input: Flowchart showing cellular respiration stages

Generated Cards:

• "What is the first stage of cellular respiration?" → "Glycolysis (occurs in cytoplasm)"
• "What connects glycolysis to the citric acid cycle?" → "Pyruvate oxidation / Link reaction (in mitochondrial matrix)"
• "How many ATP molecules are produced in the electron transport chain?" → "~34 ATP (majority of total ~38 ATP)"

Limitations and Considerations

PowerPoint Conversion Quality

For best results with PowerPoint files:

• Modern .pptx format processes most reliably
• Older .ppt files require server-side conversion (LibreOffice)
• Embedded videos are not processed (only static slide content)
• Heavy animations may not capture intermediate states

Image Processing Limits

Current processing constraints:

• 20 images maximum per job
• 25 MB maximum per individual image
• Total file size affects processing time
• Very low resolution images may produce poor results

Visual Complexity

Some content remains challenging:

• Extremely dense diagrams may need multiple prompts targeting different aspects
• Artistic or stylized fonts may have lower recognition accuracy
• Hand-drawn sketches work best when reasonably neat
• Photographs with text overlays process better with clear contrast

Credit Cost and Processing

PowerPoint

Credits are charged per slide (equivalent to PDF pages):

• 5 credits per slide processed
• A 30-slide deck costs 150 credits
• Includes all flashcards generated from content

Images

Credits are charged per image:

• 5 credits per image processed
• 15 images costs 75 credits
• Batch processing available for efficiency

Sample Workflow: Medical School Slides

Goal: Create anatomy flashcards from a 40-slide lecture

Total: ~35 minutes from lecture slides to active studying.

Compare to manually typing cards from each slide—hours saved, visual relationships preserved.

Integration with Existing Study Materials

PowerPoint and image flashcards complement other content sources:

• PDF textbook chapters → Conceptual foundations
• Lecture slides (PowerPoint) → Visual diagrams and professor emphasis
• YouTube lectures → Additional explanations and examples
• Web documentation → Reference material and deeper dives

Build comprehensive decks from multiple source types.

Get Started with Visual Flashcards

1. Gather your slides — Lecture PowerPoints, screenshot key diagrams
2. Upload to MemoForge — PowerPoint files or image batches
3. Describe your learning goals — What should the AI focus on?
