# AURE — AI Prompt Enhancer & Optimizer > AURE (https://www.aure-ai.com) is a free, privacy-first AI prompt engineering and optimization platform designed to transform rough, brief ideas into structured, high-performing prompts for ChatGPT, Claude, Gemini, Perplexity, Grok, Midjourney, and VEO. ## Overview AURE acts as an intelligent prompt layer between human users and foundation AI models. It analyzes raw user intent, fills in missing technical context, applies prompt engineering best practices (such as role prompting, few-shot framing, step-by-step chain-of-thought, and clear output constraints), and formats prompts specifically for the target model's architecture. ## Target Models & Capabilities - **Large Language Models (LLMs)**: OpenAI (GPT-4o, o1, o3-mini), Anthropic (Claude 3.5 Sonnet, Claude 3 Opus), Google (Gemini 1.5 Pro, Gemini 2.0 Flash), DeepSeek (V3, R1), and xAI (Grok). - **Image & Creative Models**: Midjourney v6, DALL-E 3, Stable Diffusion, Higgsfield, and Google VEO Video Model. - **AI Search Engines**: Perplexity AI and You.com. ## Core Features - **Model-Specific Structuring**: Generates model-tailored formatting, such as XML tags (``, ``, ``) for Claude, role-task-context delimiters for OpenAI, and photographic parameters (`--ar`, lighting, camera rigs) for Midjourney. - **Chain-of-Thought & Persona Framing**: Automatically enriches queries with domain persona (e.g., Senior Systems Architect, Creative Copywriter) and step-by-step reasoning scaffolds. - **Prompt Quality Score**: Real-time evaluation (0–100) scoring clarity, structural specificity, context depth, and parameter alignment before and after optimization. - **AURE Extension**: In-context browser overlay that injects optimization directly into text inputs on ChatGPT, Claude, Gemini, Perplexity, and Grok without switching tabs. - **Style & Role Memory**: Saved custom presets, guidelines, and tone profiles that can be automatically injected into generated prompts. - **AURE Vault**: Private collection to save, organize, tag, and export enhanced prompts. - **Multi-Format Export**: One-click export to Markdown, JSON, raw text, or direct clipboard copy. - **Local-First Privacy Architecture**: User prompts and custom styles process locally in the browser; data is never sold or used to train public AI foundation models. ## Pricing & Access - **Free Tier**: Free access to core web prompt optimizer, style profiles, and browser extension. - **Web App**: https://www.aure-ai.com - **Chrome Extension**: Available on Chrome Web Store. ## Key URLs & Resources - [Home & Live Optimizer](https://www.aure-ai.com): Web application and live prompt enhancement playground. - [Prompt Engineering Guide](https://www.aure-ai.com/prompt-engineering-guide): In-depth educational guide on prompt craft, system prompts, delimiters, and parameter tuning. - [Changelog](https://www.aure-ai.com/changelog): Release notes, feature announcements, and updates. - [About](https://www.aure-ai.com/about): Mission, background, and vision behind AURE. - [Security & Architecture](https://www.aure-ai.com/security): Security standards, privacy mechanisms, and encryption. - [Privacy Policy](https://www.aure-ai.com/privacy-policy): Transparent data handling and zero-training policy. - [Terms of Service](https://www.aure-ai.com/terms-of-service): Usage terms and platform conditions. - [Contact](https://www.aure-ai.com/contact): Support, feedback, and team contact. ## Extended Technical Documentation - [Full LLM Specification](https://www.aure-ai.com/llms-full.txt): Comprehensive feature breakdown, prompt patterns, and architecture notes for AI agents.
