🧾 Generate Project Summary from meeting transcript

Who’s it for 🤝

  • Project managers looking to automate client meeting summaries
  • Client success teams needing structured deliverables from transcripts
  • Agencies and consultants who want consistent, repeatable documentation

How it works / What it does ⚙️

  1. Trigger: Manual or webhook trigger kicks off the workflow.
  2. Get meeting transcript: Reads the raw transcript from a specified Google Docs file.
  3. Generate summary: Sends transcript + instructions to OpenAI (gpt-4.1-mini) to produce a structured project summary.
  4. Convert to HTML: Transforms the LLM-generated Markdown into styled HTML.
  5. Prepare request: Wraps HTML and metadata into a multipart request body.
  6. Create Google Doc: Uploads the new “Project Summary” document into your Drive folder.

How to set up 🛠️

    • Google Docs & Drive OAuth2 credentials
    • OpenAI API key (gpt-4.1-mini)
