What is PromptPerfect

PromptPerfect is Jina AI’s prompt optimization and testing platform for developers and power users of ChatGPT, Claude, GPT API, and similar. It turns rough, ad-hoc prompts into clearer, more effective prompts.

Main features

• Prompt optimization: Paste your prompt and get an improved version with clearer task, format, and constraints.
• Multi-model testing: Run the same prompt across several models and compare quality, consistency, and latency.
• Templates and best practices: Scene-based templates (e.g. summarization, coding, role-play); you can adapt them.
• Versioning and evaluation: Save prompt variants and compare them with simple metrics or human labels (A/B style).

Best for
