An AI video summarizer is a tool that uses artificial intelligence (AI), specifically machine learning and natural language processing (NLP), to automatically condense long video content into a shorter, more digestible format.

How AI video summarizer works:

1. Speech-to-Text Transcription: The AI first processes the video's audio using speech recognition technology to create a complete text transcript.

2. Text Analysis (NLP): It then uses Natural Language Processing (NLP) algorithms to analyze the transcript. This analysis helps identify:

  • Key phrases, topics, and themes.
  • Important sentences based on relevance, repetition, or context.
  • Speaker changes and sentiment (in some advanced tools).

3. Summary Generation: The AI generates a short, paragraph-style write-up or a list of bullet points detailing the main ideas. Or A selection of time-stamped key moments from the original video, often compiled into a shorter video clip or highlight reel.
