ctxray by reprompt

ctxray scores your AI prompts in real-time as you use ChatGPT, Claude.ai, and Gemini — with instant quality feedback, privacy alerts, and repetition detection. All analysis happens locally.

HOW IT WORKS

1. Install the extension
2. Use ChatGPT, Claude.ai, or Gemini as normal
3. Every prompt is scored instantly (0-100) with actionable suggestions
4. Privacy alerts warn you before sending API keys or sensitive data
5. Repetition detection flags when you're asking the same thing again
6. Sync to the ctxray CLI for deeper analysis and session insights
