# ROLE B2B SaaS founder writing to a Chamber of Commerce exec director on behalf of an AI chatbot company. # OBJECTIVE Book a 15-min intro call to demo the chatbot for member businesses. # CONSTRAINTS ≤140 words, no emojis, no buzzwords, one clear CTA. # OUTPUT FORMAT Subject line + plain-text email + 1 follow-up draft.
From the first rough idea to a deployed multi-step agent — and every diff, score, and dollar in between.
Rewrite rough ideas into structured, model-portable prompts using the ROCITRCOQEV framework.
We ask the questions that actually move quality — audience, format, constraints, target model — before rewriting.
Compose persona, system prompt, tools, schemas, guardrails, and memory into reusable agents.
Run the same prompt across Claude, GPT, Gemini, and Groq side-by-side. Compare speed, cost, and quality.
Chain prompts into deterministic workflows: research → summarize → draft → publish. Variables, branching, webhooks.
Save brand voice, writing style, favorite frameworks, and reusable context blocks. Every new prompt gets your fingerprint.
Git-style version history, diff viewer, and a 0–100 prompt score across 8 dimensions.
Token usage, model effectiveness, cost-per-prompt, and team performance — all in one dashboard.
Real rough inputs, restructured into production-grade prompts.

Claude, ChatGPT (GPT-4o family), Gemini 1.5/2.x, Groq (Llama, Qwen), DeepSeek, Perplexity, Midjourney, Stable Diffusion, and any generic LLM. Optimization is model-portable by default.
No — Prompt OS ships with provider keys for the bundled lab. You can also bring your own keys per organization for unlimited runs and accurate billing.
Prompt OS is an end-to-end operating system: optimize, score, version, run multi-model, memory profiles, agents, workflows, and analytics — under one roof.
Yes. The platform runs on Postgres + Node and ships with a single Docker Compose file. Bring your own provider keys.
No. We never train on user prompts. Provider calls obey each provider's contractual policies (Anthropic, OpenAI, etc.).
