# 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.

Every layer of the prompt stack.

From the first rough idea to a deployed multi-step agent — and every diff, score, and dollar in between.

Prompt Optimization Engine

Rewrite rough ideas into structured, model-portable prompts using the ROCITRCOQEV framework.

Dynamic Clarification

We ask the questions that actually move quality — audience, format, constraints, target model — before rewriting.

AI Agent Builder

Compose persona, system prompt, tools, schemas, guardrails, and memory into reusable agents.

Multi-Model Testing Lab

Run the same prompt across Claude, GPT, Gemini, and Groq side-by-side. Compare speed, cost, and quality.

Workflow Builder

Chain prompts into deterministic workflows: research → summarize → draft → publish. Variables, branching, webhooks.

Prompt Memory

Save brand voice, writing style, favorite frameworks, and reusable context blocks. Every new prompt gets your fingerprint.

Versioning + Scoring

Git-style version history, diff viewer, and a 0–100 prompt score across 8 dimensions.

Analytics

Token usage, model effectiveness, cost-per-prompt, and team performance — all in one dashboard.

Before → after.

Real rough inputs, restructured into production-grade prompts.

FAQ

Which LLMs does Prompt OS support?+

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.

Do I need my own API keys?+

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.

How is this different from PromptPerfect or FlowGPT?+

Prompt OS is an end-to-end operating system: optimize, score, version, run multi-model, memory profiles, agents, workflows, and analytics — under one roof.

Can I self-host?+

Yes. The platform runs on Postgres + Node and ships with a single Docker Compose file. Bring your own provider keys.

Is my data used to train models?+

No. We never train on user prompts. Provider calls obey each provider's contractual policies (Anthropic, OpenAI, etc.).
