Best practices for getting the best summaries with Copilot

Although Copilot's artificial intelligence is highly efficient, It usually delivers better results when provided with context and clear details about what is expected from the brief.Among the most effective recommendations for guiding AI are:

  • Explicitly indicate who the summary is intended for and its purpose (for example, whether it is for a high-level meeting or an internal report).
  • Request the inclusion of certain topic areas or key questions that need to be answered in the summary.
  • Specify the level of depth required, adjusting the length according to the audience that will read it.
  • Ask for specific examples of suggested questions to facilitate further analysis.

Current technical limitations of Copilot-generated summaries

Despite its advantages, Copilot has some important technical restrictions to be aware of.:

  • Automatic summaries are only available if you have a Microsoft 365 Copilot license and the document is stored in OneDrive or SharePoint. If the file is saved elsewhere, the summary must be activated manually..
  • The document must be at least 20 words long for Copilot to generate a summary, as shorter files don't contain enough information for the AI ​​to synthesize.
  • The maximum word limit is approximately 1,5 million words, which is equivalent to about 300 pages for the most detailed version of the abstract. For standard or short summaries, the limit is considerably lower., but it is still sufficient for most professional or academic uses.
  • Although Copilot is capable of processing the entire document content, it sometimes fails to generate direct citations for each extracted argument, something that is being progressively improved in updates.

These limitations should be considered especially in corporate or educational environments where documents can vary greatly in size and format. However, within these limits, the functionality covers virtually all common summarization needs.
