+# **App Name**: PromptVerse
+
+## Core Features:
+
+- Prompt Creation: Create and save new prompts with a user-friendly interface, offering options to format the prompt and add context notes.
+- Prompt Organization: Organize prompts using tags and categories. Include hierarchical categories.
+- Robust Search: Enable powerful search functionality to quickly find prompts by keywords, tags, or categories.
+- One-Click Copy: Allow users to copy prompts to the clipboard with a single click for easy use in other applications.
+- AI-Powered Tagging: Suggest relevant tags for the prompt using AI. The AI tool should extract important keywords from the prompt to improve searchability and organization.
+
+## Style Guidelines:
+
+- Primary color: Deep indigo (#4B0082) for a professional feel with a hint of creativity.
+- Background color: Dark slate gray (#303030) to implement a sleek dark mode theme.
+- Accent color: Electric purple (#BF40BF) for interactive elements and highlights to guide the user.
+- Body and headline font: 'Inter' sans-serif for a modern, machined, objective, neutral look.
+- Use minimalist icons that are easily recognizable on a dark background. Prefer sharp, geometric designs for a modern feel.
+- Implement a grid-based layout, similar to Google Keep, for organizing prompts. Use subtle shadows to create a frosted glass effect (similar to Apple Vision Pro). Utilize a card-based interface for each prompt.
+- Subtle animations on hover and click events. Smooth transitions between pages or sections. A brief 'copied to clipboard' confirmation that elegantly fades in and out when copying prompts.
