Who It’s For

This template is ideal for:

• Students: Automatically turn lectures or study group audio into summarized notes.
• Professionals: Log meeting notes and summaries directly into your Notion workspace.

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.).

Setup Instructions

• Step 1: Google Drive Trigger Connect your Google Drive account. Select the folder you want to monitor. This node detects new file uploads and passes the file for download.

• Step 2: Download File Downloads the new audio file for transcription. Step 3: Transcribe Recording (OpenAI Whisper) Connect your OpenAI API Key. Ensure this node receives the binary audio file. It will return the transcription as plain text.

• Step 3: Transcribe Recording (OpenAI Whisper) Connect your OpenAI API Key. Ensure this node receives the binary audio file. It will return the transcription as plain text.

• Step 4: Summarize Transcript (GPT-4 via AI Agent) Use your OpenAI API Key. Configure a summarization prompt like: “Summarize the following transcript in a clear and concise manner:” Connect the output from Whisper into this GPT-4 prompt.

• Step 5: Notion Integration Connect your Notion account. Choose or create a database to store summaries. Map the GPT output (summary) to a “Text” or “Rich Text” property. Optionally include metadata like filename, file upload date, etc.
