PromptStudio is an all-in-one platform for prompt creation, testing, and refinement. It brings together tools for authoring, context weighting, A/B testing, versioning, and analytics into a single cohesive workspace. Building on lessons from my earlier projects PromptBox and Prompt Canvas, it evolves them into a cleaner, more comprehensive tool for AI-native work. The platform supports both structured textual editing and visual composition, ensuring experimentation is both creative and reproducible.

A unique aspect of PromptStudio is its local-first AI runtime. Instead of depending solely on cloud APIs, it leverages WebGPU to run a local DeepSeek R1 model directly in the browser, enabling faster feedback loops, lower latency, and greater privacy. This approach allows users to stream tokens live, ground responses in their own documents, and inspect how prompts are being compiled and executed, all without leaving their device.

The project is still in development, but the vision is clear: make prompt engineering structured, visual, and reproducible, while showing how lightweight models and modern browser capabilities can empower a new generation of AI-native tools. UI/UX revisions and advanced model usage in R&D currently.
