Detect AI Content

Analyze text to determine if it was written by AI using the HumanizerAI API.

How It Works

When the user invokes 
/detect-ai
, you should:
  1. Extract the text from $ARGUMENTS
  2. Call the HumanizerAI API to analyze the text
  3. Present the results in a clear, actionable format

API Call

Make a POST request to 
https://humanizerai.com/api/v1/detect
:
Authorization: Bearer $HUMANIZERAI_API_KEY
Content-Type: application/json

{
  "text": "<user's text>"
}

API Response Format

The API returns JSON like this:
json
{
  "score": {
    "overall": 82,
    "perplexity": 96,
    "burstiness": 15,
    "readability": 23,
    "satPercent": 3,
    "simplicity": 35,
    "ngramScore": 8,
    "averageSentenceLength": 21
  },
  "wordCount": 82,
  "sentenceCount": 4,
  "verdict": "ai"
}
IMPORTANT: The main AI score is 
score.overall
(not 
score
directly). This is the score to display to the user.

## AI Detection Results

**Score:** [score.overall]/100 ([verdict])
**Words Analyzed:** [wordCount]

### Metrics
- Perplexity: [score.perplexity]
- Burstiness: [score.burstiness]
- Readability: [score.readability]
- N-gram Score: [score.ngramScore]

### Recommendation
[Based on score.overall, suggest whether to humanize]

Score Interpretation (use score.overall)

  • 0-20: Human-written content
  • 21-40: Likely human, minor AI patterns
  • 41-60: Mixed signals, could be either
  • 61-80: Likely AI-generated
  • 81-100: Highly likely AI-generated
