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.
- 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.
Transcribe and Summarize Audio with Whisper and GPT from Google Drive to Notion
This n8n workflow automates the process of transcribing audio files from Google Drive using OpenAI's Whisper, summarizing the transcription with an OpenAI GPT model, and then publishing the results to Notion.
What it does
- Monitors Google Drive: Listens for new or updated audio files in a specified Google Drive folder.
- Downloads Audio: Retrieves the audio file from Google Drive.
- Transcribes Audio (Whisper): Sends the audio file to OpenAI's Whisper API for transcription into text.
- Summarizes Transcription (GPT): Uses an OpenAI Chat Model (GPT) to generate a concise summary of the transcribed text.
- Publishes to Notion: Creates a new page or updates an existing one in Notion with the original transcription and the generated summary.
Prerequisites/Requirements
- n8n Account: A running n8n instance (cloud or self-hosted).
- Google Drive Account: Configured with n8n credentials and a designated folder for audio files.
- OpenAI API Key: An OpenAI API key with access to Whisper and GPT models.
- Notion Account: Configured with n8n credentials and a Notion database/page where the results will be published.
Setup/Usage
- Import the Workflow: Download the provided JSON and import it into your n8n instance.
- Configure Credentials:
- Google Drive Trigger: Set up your Google Drive OAuth2 credentials. Specify the folder ID you want to monitor for audio files.
- Google Drive Node: Use the same Google Drive credentials to download the file.
- OpenAI Node: Set up your OpenAI API Key credential. This will be used for both Whisper transcription and GPT summarization.
- Notion Node: Set up your Notion API Key credential. Configure the database ID or page ID where you want to publish the transcriptions and summaries.
- Activate the Workflow: Once all credentials are set and configurations are complete, activate the workflow.
Now, whenever a new audio file is added or updated in your specified Google Drive folder, the workflow will automatically transcribe, summarize, and publish it to Notion.
