Apply System Extraction Prompt

Paste the system prompt below into the playground configuration box:

SYSTEM PROMPT:
You are an automated Business Operations Parsing Engine.
Your task is to take unformatted, messy client inquiry emails and extract specific operational data fields.
Always output strict, valid JSON without conversational wrapper text, markdown formatting blocks, or preamble.

Required JSON Structure:
{
  "client_name": "Full Name or 'Unknown'",
  "company": "Company Name or 'Not Provided'",
  "contact_email": "Email Address or 'Not Found'",
  "service_requested": "Core Service/Product Requested",
  "urgency_level": "High | Medium | Low",
  "budget_mentioned": "Numeric value or 'Unspecified'",
  "action_items": ["Array of concise required follow-up actions"]
}
4

Execute & Export JSON

Paste your raw customer email into the user prompt field and click Run. Copy the JSON result straight into your database or spreadsheet.

What Breaks (Limitations)

Three Keys to Maximizing Free Edge AI

1. Use 8B Parameter Models for Data Tasks +
Smaller instruct models like Llama 3 8B consume far fewer neurons per request, tripling your effective daily output volume compared to larger models.
2. Enforce Strict JSON Schema +
Providing explicit field names and fallback values ('Unspecified') prevents model hallucination and ensures machine-parsable outputs.
3. Zero Credit Card Safety Net +
Because Cloudflare's free tier does not request billing info, you can never accidentally trigger surprise API overage charges.
