PromptOps

PromptOps is a native iOS prompt engineering studio for builders who treat AI prompts as production code — not throwaway text in a chat box. Build prompts with structure. Test them across multiple AI models. Score them with rule-based and model-graded evaluators. Track every version. Bundle them into ordered chains. All on-device, with your own API keys. WHY PROMPTOPS Most prompt tools are web apps with someone else's database, someone else's keys, and someone else's pricing. PromptOps runs entirely on your iPhone or iPad with the API keys you already have. No accounts. No servers. No middlemen. WORKS WITH THE MODELS YOU ALREADY USE • OpenAI (GPT-4o, GPT-4, GPT-3.5) • Anthropic (Claude family) • Google (Gemini) • xAI (Grok) • Ollama (local models on your network) • Any OpenAI-compatible endpoint (Groq, Together, Fireworks, Azure, custom) PROMPT ENGINEERING ESSENTIALS • 47 production-ready templates across writing, coding, research, data, agents, RAG, vision, and more • {{variable}} placeholders with types, defaults, and validation rules • Categories and tags for organizing your library • Automatic versioning on every edit — full history, instant rollback • Draft → Published → Deprecated lifecycle • Streaming responses where supported EVALUATE LIKE A PROFESSIONAL • 14 built-in evaluators including json_valid, regex_match, contains, schema_valid, exact_match, similarity, and model-graded scoring • Build evaluation suites with weighted rules and pass thresholds • Run suites against test datasets to catch regressions • Compare scores across versions and models PRO FEATURES • Skills — ordered bundles of prompts that run as a parallel batch or as a chain, where each step's output feeds the next • Side-by-side Compare — run the same prompt across two models or two versions and diff the output • Regression Check — replay every prior execution against a new version and see what changed • Sync — push and pull your prompt library to GitHub or iCloud • Custom providers — add any OpenAI-compatible API PRIVACY-FIRST Your prompts, executions, and API keys never leave your device. PromptOps collects no data. API calls go directly from your iPhone or iPad to the AI provider you've configured. Keys are stored in iOS Keychain.
