What Is an AI Video Summarizer?

An AI video summarizer is a software that watches and analyzes a video and generates a summary of its key ideas, topics, or segments. Some tools simply extract highlights from spoken content, while others can recognize visual scenes or speaker transitions.

These tools are designed to:

Help students summarize lecture videos for study

Allow professionals to extract meeting action items

So, yes. AI can watch a video and summarize it, though the method depends on the tool.
