What Is Windows Recall?
At its core, Windows Recall is an AI-powered visual timeline of your computer usage:
Periodic Screen Captures: When enabled, Recall captures high-frequency visual snapshots of your desktop (roughly every few seconds) while the PC is actively in use.
Local AI Indexing: An on-device Neural Processing Unit (NPU) runs Optical Character Recognition (OCR) and computer vision to index text, images, and app contexts across these snapshots.
Visual Search Timeline: This creates a searchable, scrollable historical timeline allowing users to query natural language prompts (e.g., "Find that blue PDF invoice I looked at last Tuesday") to retrace past activity.
