Build and Deploy Production-Ready Prompts

The Helicone Prompt Editor enables you to:

  • Design prompts collaboratively in UI
  • Create templates with variables and track real production inputs
  • Connect to any major AI provider (Anthropic, OpenAI, Google, Meta, DeepSeek and more)

Version Control for Your Prompts

Take full control of your prompt versions:

  • Track versions automatically in code or manually in UI
  • Switch, promote, or rollback versions instantly
  • Deploy any version using just the prompt ID

Prompt Editor Copilot

Write prompts faster and more efficiently:

  • Get auto-complete and smart suggestions
  • Add variables (⌘E) and XML delimiters (⌘J) with quick shortcuts
  • Perform any edits you describe with natural language (⌘K)

Real-Time Testing

Test and refine your prompts instantly:

  • Edit and run prompts side-by-side with instant feedback
  • Experiment with different models, messages, temperatures, and parameters

Auto-Improve (Beta)

We’re excited to launch Auto-Improve, an intelligent prompt optimization tool that helps you write more effective LLM prompts. While traditional prompt engineering requires extensive trial and error, Auto-Improve analyzes your prompts and suggests improvements instantly.

How it Works

  1. Click the Auto-Improve button in the Helicone Prompt Editor
  2. Our AI analyzes each sentence of your prompt to understand:
    • The semantic interpretation
    • Your instructional intent
    • Potential areas for enhancement
  3. Get a new suggested optimized version of your prompt

Key Benefits

  • Semantic Analysis: Goes beyond simple text improvements by understanding the purpose behind each instruction
  • Maintains Intent: Preserves your original goals while enhancing how they’re communicated
  • Time Saving: Skip hours of prompt iteration and testing
  • Learning Tool: Understand what makes an effective prompt by comparing your original with the improved version

Using Prompts in Your Code

If you’ve created a prompt in the UI, you can use the Generate API for a simplified integration that works with multiple LLM providers.
