PhoMo

PhoMo is an AI-powered idea generator built with n8n and Google Gemini. This guide shows you how to install, run, and keep workflows saved.

1. Install n8n

Option A: Node.js (quick start)

Requires Node.js >=18.

npm install -g n8n
n8n

Option B: Docker (recommended, saves workflows)

docker run -it   --name n8n   -p 5678:5678   -v ~/.n8n:/home/node/.n8n   n8nio/n8n

• n8n UI: http://localhost:5678
• The -v ~/.n8n:/home/node/.n8n ensures workflows and credentials are saved.

2. Get a Google Gemini API Key

1. Open https://aistudio.google.com/
2. Create a new API key
3. Copy it (looks like AIza...)

3. Add Credentials in n8n

1. Go to http://localhost:5678
2. Click Credentials → New
3. Choose Google PaLM / Gemini API
4. Paste your API key and save

4. Import PhoMo Workflows

1. Download from repo’s N8N folder:
   • PhoMo_context-N8N.json
   • PhoMo_image-N8N.json
2. In n8n: Import → From File → choose each file
3. Link your Gemini credential when asked

Now you have 2 workflows:

• Text idea generator
• Image generator

5. Run the Workflow

1. In the workflow editor, click the Webhook node → copy the test URL (example: http://localhost:5678/webhook-test/idea-request)
2. Send a request:

curl -X POST http://localhost:5678/webhook-test/idea-request   -H "Content-Type: application/json"   -d '{
        "action": "choose",
        "query": {
          "scope": "การศึกษา",
          "purpose": "พัฒนาหลักสูตร",
          "addition": "ใช้เทคโนโลยี AI"
        }
      }'

You will get an AI-generated JSON response.
Run the image workflow the same way for images.

6. Make Workflows Live

• Toggle workflow Active (top right)
• Use the production webhook (example: http://localhost:5678/webhook/idea-request)

7. Run the PhoMo Website

1. Download the repo files and replace your_webhook with your webhook url

   my-site/
   ├─ index.html
   ├─ service.html
   ├─ contact.html
   ├─ css/
   ├─ js/
   ├─ img/
   ├─ N8N/
   

2. Run the site locally:

Python (comes pre-installed on macOS/Linux/Windows):

cd my-site
python3 -m http.server 8000

Open: http://localhost:8000

Node.js:

npm install -g serve
serve .

Open the given URL (usually http://localhost:5000)

VS Code (if installed):

• Install Live Server extension
• Right-click index.html → Open with Live Server
