PromptOT is a prompt management platform for AI teams. Build prompts from structured, typed blocks — role, context, instructions, guardrails, and output format — instead of managing raw text strings. Every edit creates a versioned snapshot with instant rollback. Deliver compiled prompts to any application with a single API call using environment-scoped keys that separate development from production. Teams collaborate across roles: engineers define structure, domain experts and product managers edit content directly without touching code. Built-in AI co-pilot helps improve prompt quality through conversational editing. Supports webhook notifications for CI/CD integration and 23 MCP tools for use with Claude Desktop, Cursor, and ChatGPT. Free tier available, no credit card required.
