Digitize Business Cards to Notion Database with Gemini Vision OCR

This n8n workflow automates the process of extracting information from business card images using Google Gemini Vision AI and then organizing that data into a Notion database. It simplifies the task of digitizing physical business cards, making networking more efficient.

What it does

1. Triggers on Form Submission: The workflow starts when a new submission is received via an n8n Form Trigger. This form is expected to include an image file of a business card.
2. Extracts Text with Gemini Vision: It sends the submitted business card image to Google Gemini Vision AI. Gemini Vision then performs Optical Character Recognition (OCR) to extract all text from the image.
3. Processes Extracted Data: A Code node then takes the raw text output from Gemini Vision and processes it. This step is crucial for parsing the unstructured text into structured data fields (e.g., Name, Company, Title, Email, Phone).
4. Adds to Notion Database: Finally, the structured business card information is added as a new item to a specified Notion database.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Notion Account: A Notion workspace and a database set up to store business card information (e.g., with properties for Name, Company, Title, Email, Phone, etc.). You'll need to create an integration and obtain an API token for Notion.
• Google Gemini API Key: Access to the Google Gemini API with Vision capabilities. You'll need an API key for authentication.

Setup/Usage

1. Import the Workflow:
   • In your n8n instance, go to "Workflows".
   • Click "New" or "Import from JSON".
   • Paste the provided JSON workflow definition.
2. Configure Credentials:
   • Notion: Create a new Notion credential. You'll need your Notion API token and the ID of your business card database.
   • Google Gemini: Create a new Google Gemini credential using your API key.
3. Configure the "On form submission" Trigger:
   • Activate the "On form submission" node. This will generate a unique webhook URL.
   • Share this URL or embed the generated form where you want users to upload business card images.
4. Configure the "Code" Node:
   • The "Code" node contains JavaScript logic to parse the text extracted by Gemini Vision. You might need to adjust this script based on the typical layout of your business cards and the specific fields you want to extract.
   • Example fields to extract (and map to Notion):
     • Name
     • Company
     • Title
     • Email
     • Phone Number
     • Website
     • Address
5. Configure the "Notion" Node:
   • Select the Notion credential you created.
   • Choose the "Database Item" resource and "Create" operation.
   • Map the output fields from the "Code" node (e.g., {{ $json.name }}) to the corresponding properties in your Notion database.
6. Activate the Workflow: Once all nodes are configured and credentials are set, activate the workflow.

Now, whenever a business card image is submitted via the n8n form, the workflow will automatically process it and add the digitized information to your Notion database.
