"content": "## Store Notion's Pages as Vector Documents into Supabase\n\n**This workflow assumes you have a Supabase project with a table that has a vector column. If you don't have it, follow the instructions here:** [Supabase Vector Columns Guide](https:\/\/supabase.com\/docs\/guides\/ai\/vector-columns)\n\n## Workflow Description\n\nThis workflow automates the process of storing Notion pages as vector documents in a Supabase database with a vector column. The steps are as follows:\n\n1. **Notion Page Added Trigger**:\n - Monitors a specified Notion database for newly added pages. You can create a specific Notion database where you copy the pages you want to store in Supabase.\n - Node: `Page Added in Notion Database`\n\n2. **Retrieve Page Content**:\n - Fetches all block content from the newly added Notion page.\n - Node: `Get Blocks Content`\n\n3. **Filter Non-Text Content**:\n - Excludes blocks of type \"image\" and \"video\" to focus on textual content.\n - Node: `Filter - Exclude Media Content`\n\n4. **Summarize Content**:\n - Concatenates the Notion blocks content to create a single text for embedding.\n - Node: `Summarize - Concatenate Notion's blocks content`\n\n5. **Store in Supabase**:\n - Stores the processed documents and their embeddings into a Supabase table with a vector column.\n - Node: `Store Documents in Supabase`\n\n6. **Generate Embeddings**:\n - Utilizes OpenAI's API to generate embeddings for the textual content.\n - Node: `Generate Text Embeddings`\n\n\n7. **Create Metadata and Load Content**:\n - Loads the block content and creates associated metadata, such as page ID and block ID.\n - Node: `Load Block Content & Create Metadata`\n\n8. **Split Content into Chunks**:\n - Divides the text into smaller chunks for easier processing and embedding generation.\n - Node: `Token Splitter`\n\n\n\n"

}How to Use an n8n Template
1
Create a New Workflow
Click "New Workflow" in your n8n dashboard to get started.
2
Copy & Paste Template
First, copy this template:
Click here to copy the JSON
.
Then, in n8n, click the three dots (···) → "Import from file" and paste the JSON code.
3
Customize the Nodes
Go through each node in the workflow to update inputs like spreadsheet IDs, email addresses, or message content. Adjust field mappings to match your data.
4
Grant Access
For nodes that connect to external apps (like Google Sheets or Slack), you'll need to grant access. Connect your accounts using OAuth or an API key and save the credentials in the node.
5
Test It
Run the workflow by clicking "Execute Node" for each step or "Run Once" for the whole thing. Check the right sidebar to inspect data and debug any errors (they'll show up in red).
6
Activate Workflow
Once everything works as expected, click the "Activate" toggle to turn your workflow on. You're all set!
