🕳️ PIT (Prompt Information Tracker)

Git for Prompts — Version control that actually understands your LLM prompts

---

🚀 What is PIT?

PIT is a semantic version control system designed specifically for managing LLM prompts. Unlike traditional Git workflows, PIT understands the meaning of your prompts—tracking not just what changed, but why it matters for your AI's behavior.

Stop treating prompts like plain text files. Start versioning them like the critical assets they are.
