Features

⚡ Code Optimization

Improves your code automatically. Converts blocking code to non-blocking variants, replaces delay() with millis()-based implementations, and more.

🔍 Code Explanation

Explains complex commands, hardware registers, and library functions in plain language — perfect for beginners and experts alike.

📝 Automatic Documentation

Adds meaningful comments to your existing code with a single click.

🔧 Error Analysis

Paste a compiler error and get a clear explanation plus a concrete fix. Works with Arduino IDE and VS Code diagnostics.

❓ Ask AI

Ask anything — with or without selected code. Follow-up questions keep the context alive.

🐛 Debug Help

Serial Monitor output analysis
Hardware diagnostics for common wiring problems
Timing analysis (blocking vs. non-blocking)

💬 AI Chat

Multiple persistent chat sessions, just like in your browser — but right inside the IDE. Attach files, reference your sketch, and continue where you left off.

🤖 Custom Agents

Define your own AI workflows: error checking after compile, code review, documentation generation — with access to build output, sketch files, and external resources.

🚀 Agentic Coding

The AI reads, modifies, and writes your project files directly — no copy-pasting required. It can even compile and fix errors autonomously in a loop.

📊 Offline Code Analysis

Get structural information about your current file without any API call.

✨ Inline Completion

AI-powered code suggestions as you type (optional, configurable).
