ULTRACODEAI - IntelliJ AI Assistant (Ultra-fast, Local + Cloud LLMs)

An IDE-first AI copilot for IntelliJ IDEA with chat, diagnostics, and project-aware insights.

🚀 Overview

UltraCodeAI is an IntelliJ IDEA plugin that embeds an AI coding copilot directly in the IDE:

Multi-model chat with streaming responses
Real‑time Diagnostics tab powered by IntelliJ inspections
Project‑aware Insights (RAG-ready structure)
One clean, native, tabbed tool window: Chat • Diagnostics • Insights

It works with both local models (privacy-first) and cloud models (frontier capabilities), and is built 100% in Java for deep IntelliJ integration.

🌟 Key Features

Feature	Description
🤖 Unified Chat UI	A single, tabbed interface for AI chat, code diagnostics, and project insights. No more cluttered windows.
🔌 Multi-LLM Support	Connect to local LLMs for privacy or cloud LLMs for power. Switch between them effortlessly.
⚡ Streaming Responses	Get token-by-token responses for a real-time, interactive chat experience.
🔍 Live Code Diagnostics	The "Diagnostics" tab automatically analyzes your open file, providing AI-powered explanations and fixes for errors and warnings.
💡 Hover-to-Explain	Simply hover over any piece of code—a variable, function, or class—to get an instant AI-generated explanation.
🧠 Context-Aware Prompts	Easily add files, directories, or code snippets to your prompt context. The AI knows what you're working on.
🛠️ RAG-Enhanced Insights	Built with a Retrieval-Augmented Generation architecture to provide project-aware insights and more accurate answers.
🎨 Native Look & Feel	A beautiful UI built with JetBrains Swing components that respects your IDE theme and feels like a part of IntelliJ.

🚀 Features & Tech

Configuration & Setup 🛠️

Settings: UltraCodeAI → provider selection (local/cloud) → API keys → appearance/cost/context preferences → MCP/Web Search/RAG toggles
Access: : View → Tool Windows → UltraCodeAI

Core Usage 🎯

Chat: Open tool window → type prompt + code context → real-time streaming
Context: Right-click files → "Add To Conversation" → directory/token calculation
Diagnostics: Auto-populate from IntelliJ analyzer → click navigation
Insights: RAG-powered contextual recommendations

Architecture Components 🏢

UltraCodeAIToolWindowFactory:** 3-tab UI + Chat send-button → PromptExecutionService.executePrompt()
PromptExecutionService: Command processing → strategy selection → execution → cancellation → cleanup
ResponseListener:** onTokenReceived + onComplete interface
UltraCodeAIDiagnosticsService: IntelliJ daemon analyzer → Diagnostics tab callback

Extension Points 🔗

Providers: Custom local/cloud services (chatmodel/) - Strategies: New PromptExecutionStrategy variants - RAG: Indexer/retriever for Insights - WebView: JCEF/HTML+Prism rendering - Actions: Editor/project context integration

Roadmap 🗺️

Click-navigate diagnostics - AI fix suggestions - Rich JCEF chat rendering - Provider presets - Smart model recommendations - Full RAG + local embeddings
