Track and visualize daily moods with GPT-4o, Wolfram Alpha, Sheets, and Slack

Overview

This workflow, "Mood Graph Studio," offers a comprehensive solution to track and visualize your emotional well-being. By simply inputting a single sentence about your mood, this template uses AI to perform a sentiment analysis, generates a visual graph via Wolfram Alpha, provides personalized feedback, and logs everything to Google Sheets.

It is designed for anyone interested in mindfulness, self-reflection, or quantified self-tracking.

How It Works

The workflow is divided into two main API functionalities and a manual trigger for easy testing.

1. Analyze a Single Mood (/mood endpoint)

• An AI Agent (OpenAI) quantifies your mood text into valence (positivity) and energy (activity).
• A query is sent to Wolfram Alpha to generate a simple linear graph based on the score.
• A second AI Agent provides short, encouraging advice in Japanese.
• The complete entry is logged as a new row in Google Sheets.
• Returns a JSON response containing the full analysis and the graph image.

2. Generate Mood History Graph (/history endpoint)

• Retrieves historical mood data for a specified user from Google Sheets.
• A Code node formats the data into a time-series plot query.
• Wolfram Alpha generates a line graph visualizing the mood trend over time.
• The resulting graph is automatically posted to Slack.

How to Set Up

1. Credentials

You must add your own credentials for the following services in the respective nodes:

• OpenAI: Used in both Chat Model nodes.
• Google Sheets: Used in the "Log Mood" and "Get History" nodes.
• Slack: Used in the "Send History" node.

2. Wolfram Alpha App ID

This workflow uses the HTTP Request node to call the Wolfram Alpha API.

• Get a free App ID from the Wolfram|Alpha Developer Portal.
• Paste your App ID into the appid parameter value in both Generate...Graph nodes.

3. Google Sheet Configuration

• Create a new Google Sheet.
• Paste the Sheet ID into the Document ID field in both Google Sheets nodes.
• Crucially, ensure the first row has the following headers exactly (case-sensitive): userId, moodText, valence, energy, createdAt, wolframQuery, feedback

How to Use

For Testing: Use the Manual Trigger. Modify the sample text in the "Set Test Data" node and click "Execute Workflow" on the canvas.

For Production: Activate the workflow. Send POST requests to the Production URL of the Webhook nodes.
