Prompt Optimizer

Active
GitHub TypeScript NOASSERTION

Description

An AI prompt optimizer that helps users write better prompts and achieve improved AI results.

Key Features

  • One-click Intelligent Optimization — Input simple prompts; AI auto-generates optimized versions with multi-round iteration
  • Dual Mode Optimization — Supports both system prompt and user prompt optimization for different scenarios
  • Multi-model Integration — Supports OpenAI, Gemini, DeepSeek, Grok, Zhipu AI, SiliconFlow, and more
  • Image Generation Optimization — T2I, I2I, and multi-image generation with Gemini, Seedream, Grok models
  • Advanced Testing Mode — Context variable management, multi-turn conversation testing, and Function Calling support
  • Client-side Security — All data stored locally; direct interaction with AI providers; no intermediate servers

Use Cases

💡 Optimize ChatGPT or Claude system prompts to improve AI output quality and consistency
💡 Write more effective instruction prompts for AI coding agents like Cursor and Copilot
💡 Test and evaluate different prompt versions through comparative analysis to find the best approach
💡 Optimize text-to-image prompts for more precise and expected image generation
💡 Manage and reuse prompt assets in team collaboration with version history and import/export
