Add your READMEs, wikis, logs, and transcripts to your notebook

Your most useful project knowledge does not always live in a polished document. It might be captured in a README, project wiki, system log, meeting transcript, research export, or a simple text file.

Copilot Notebooks can now use Markdown (.md), rich text format (.rtf) and plain text (.txt) files as references—helping you bring more of the content your work runs on into one focused workspace. 

Add the files to a notebook, chat with Copilot, and generate grounded insights and useful artifacts from your project context.

 

 

Bring structured knowledge and raw data together

Markdown often contains the structured knowledge behind a project: READMEs, technical documentation, project wikis, architecture notes, release notes, and runbooks.

Plain-text files often contain raw data: system logs, exported transcripts, ticket dumps, customer feedback, and working notes.

Rich Text Format (.rtf) files preserve formatted notes and documents—such as reports, drafts, and exported content.

With support for Markdown, rich text, and plain-text files, Copilot Notebooks helps you bring together documentation, notes, logs, and transcripts into a single workspace for deeper insight and outcomes.

Scenarios to try

Here are a few ways to get started in notebooks:

  • Turn a transcript into action: Add an exported meeting transcript and ask, “What did we decide, who owns each action, and what remains unresolved?”
  • Find patterns in feedback: Add a plain-text export of support tickets and ask, “What are the most common issues, and which themes appear to be emerging?”
  • Investigate an incident: Add a README and system log, then ask, “Compare the expected behavior with what happened before the failure.”
  • Get up to speed on a new project: Add a project wiki, meeting transcripts, release notes, and working notes, then ask, “What do I need to know to contribute effectively to this project?”

How it works

Add a .md, .txt, or .rtf file as a reference in Copilot Notebooks, then chat with Copilot about its content.

There is no need to reformat a log, convert a transcript into a traditional document, or manually summarize a long README first. Copilot can reason over the files in the context of the notebook and provide answers grounded in the source material.

Feedback

We want to hear from you. Try bringing a README, project wiki, log, transcript, or another text-based source into a Copilot Notebook—and let us know which scenarios help you move from complex files to useful work.

More to come

We’ll continue expanding the range of content you can bring into Copilot Notebooks—including new and emerging input types—so you can work with more of the context that matters to you.

This feature is rolling out to all Copilot Notebooks users starting this week.
