About

PromptSmith is a professional-grade, privacy-first AI extension designed for developers, prompt engineers, and power users. Unlike standard AI tools that lock you into a subscription, PromptSmith acts as a transparent "shell"—you provide the API key (OpenAI, Claude, or Local LLM), and we provide the ultimate workbench to refine, manage, and execute your prompts.

🔧 Key Features
1. Bring Your Own Endpoint (BYOE) & Model Agnostic Connect directly to your preferred AI providers. Whether it's the latest GPT-4 via OpenAI, Claude 3, or a private Local LLM proxies, PromptSmith connects to any standard API endpoint. You pay the provider directly—no middleman markups.

2. "Strategy" Engine: Built-in Optimization Don't just chat; engineer your output.

Auto-Optimization: Use our built-in "Refinement Strategy" to instantly polish vague ideas into high-quality, structured prompts before sending them to the AI.

Custom Workflows: Create and save your own Strategies (combining custom System Prompts + User Prompts) for recurring tasks like code review, translation, or SEO analysis.

3. Local-First Privacy Your data belongs to you. PromptSmith stores your API keys, chat history, and custom strategies locally in your browser. We never transmit your data to our servers.


🚀 Why You Should Install PromptSmith
Stop Paying "AI Tax": Most extensions charge you $20/month just to resell you cheap API access. With PromptSmith, you use your own keys, paying only for what you use (often less than $5/month for heavy usage).

Better Results, Less Frustration: The raw API is powerful but hard to control. Our "Strategy" feature acts as a quality assurance layer, ensuring your prompts are optimized before you spend tokens on them.

Total Freedom: You are not limited by a vendor's model choice. Switch between a local model for free privacy and a cloud model for complex reasoning in seconds.

Forge your intelligence. Install PromptSmith today.
