About AI Prompt Architect

AI Prompt Architect is the prompt engineering platform built for production AI. Instead of ad-hoc chatting, engineers use structured frameworks like STCO (Situation, Task, Constraints, Output) to build testable, version-controlled prompts that perform consistently across GPT-4o, Claude, and Gemini.

Key features:

  • Prompt Scoring: Automated quality scoring on structure, clarity, and completeness.

  • Multi-model Evaluation: Test prompts across OpenAI, Anthropic, and Google models simultaneously.

  • CLI + MCP Integration: 50% discount for AI agents using the CLI or MCP server.

  • Enterprise Library: Organise, share, and govern prompts across teams.

  • BYOK Security: Bring Your Own Key architecture means keys never touch our servers.
