Who It’s For

This template is ideal for:

• Researchers: Transcribe and summarize interviews, lectures, or research recordings.
• Content Creators: Convert podcasts or videos into transcripts and social captions/show notes.

How It Works

This four-step workflow performs the following:

• Step 1: Trigger: New Audio in Google Drive
  Automatically triggers when a new audio file (MP3/WAV) is uploaded to a specified Google Drive folder.The file is then downloaded for processing.

• Step 2: Transcribe Audio with Whisper
  The audio file is sent to OpenAI’s Whisper model for high-accuracy transcription.

• Step 3: Summarize Transcript with GPT-4
  The transcript is passed to GPT-4, which generates a clean, concise summary.

• Step 4: Store Summary in Notion
  A new Notion page is created with the generated summary and optional metadata (file name, upload time, etc.).
