Hide parts of an image and test yourself on what is underneath. Flashka’s AI auto-detects likely labels and creates the hidden regions for you.
🏁 Where you can create them
From PDF view: use the Occlusion Tool and press O to start dragging masks over the image.
From Flashcards view: open Add Card and choose Image Occlusion. You can also upload a new image here.
🛠️ Edit and customise
Delete any auto-created mask you do not need.
Resize or move masks by dragging their edges.
Draw new masks anywhere to add more prompts.
💸 Cost
Free feature. No credits required.
💡 Tips
Keep one fact per mask for clean recall.
If an area feels crowded, split it into multiple smaller masks.
