## About

Langtail is a platform that helps developers build, test, and deploy applications powered by LLMs faster. With Langtail, you can go from prototype to production-ready apps in less time.

Key features:
• Collaborative workspaces - Invite your team to collaborate on prompt engineering and app development. 
• No-code LLM Playground - Prototype, debug and test prompts without writing code. Supports OpenAI models, more providers coming soon.
• Centralized logs and analytics - Get insights into your LLM's performance, costs, and usage patterns. Essential for monitoring and debugging.
• Prompt evaluation - Create test suites with inputs and expected outputs. Use deterministic evaluators to verify LLM responses.
• Prompt deployment - Deploy prompts as API endpoints separate from your codebase. Manage multiple environments like prod, staging and dev.
• Vendor-agnostic - Avoid lock-in and switch between LLM providers easily. 

Langtail provides the tools to make your LLM-powered apps more predictable, performant and maintainable, whether you're building chatbots, document Q&A, text summarization, AI copilots, or workflow automation.
