  2. 2.Load the document and split it into manageable sections using recursive character splitting
  3. 3.Send each chunk to OpenAI's language model chain for intelligent summarization
  4. 4.Merge all partial summaries into a unified final summary

Use cases

  • Extract key points from contracts and legal documents efficiently
  • Convert long meeting transcripts into concise executive summaries

Requirements

  • Valid OpenAI API key with appropriate permissions
  • Text or document files in processable formats
  • Data limits configured to prevent excessive API usage costs
