Alex Sidebar’s agents are specialized AI assistants, each trained for specific development tasks. Alex automatically selects the right agent for your workflow for autonomously handling your development tasks!
Agent mode is now always on! Claude Sonnet 4 is the recommended model for its superior code generation capabilities, but you can now use other supported models including:
  • Claude 3.5 Sonnet
  • Gemini 2.5 Pro
  • Gemini 2.5 Flash
  • OpenAI o3
  • OpenAI o4 Mini
  • OpenAI GPT 4.1
  • DeepSeek R1
  • DeepSeek V3 (03.24)
Choose your preferred model from the model selector while maintaining all agent capabilities.

Quick Actions

Build & Fix Errors

One-click automatic build, error detection, and fix application. Alex continuously rebuilds until your project compiles successfully.

Smart Automation

Let agents handle repetitive tasks while you focus on core development work.

Multi-Model Support

Switch between different AI models while maintaining agent capabilities and context.

​
Understanding Agents

Agents work best by:
  • Learning your project structure and patterns
  • Maintaining contextual understanding across sessions
  • Automatically building and running your app after changes
  • Detecting and fixing compilation errors in a continuous loop
  • Taking screenshots for verification and debugging
You can make agents more effective over time by providing more notes about your project and coding preferences. Learn more about project notes here.

Getting Started

1

Toggle Auto-Apply

Press Command + Shift + A to toggle auto-apply for code changes. When enabled, code suggestions will be automatically applied to your files.
2

Project Introduction

Use voice or text to describe your project:
"This is an iOS app using SwiftUI and MVVM architecture. 
The main features include user authentication and data persistence."
3

Let Agent Learn

The agent will:
  • Analyze project structure
  • Study coding patterns
  • Build contextual understanding
  • Use regex search to find relevant code patterns

​
Automatic Build & Run

Alex Sidebar’s agent automatically builds and runs your project after making changes, creating a seamless development experience.
While the agent handles most errors automatically, always review the final changes to ensure they align with your project’s requirements.

​
Best Practices

Clear Communication

Provide specific requirements and context for best results

Iterative Development

Break complex tasks into smaller, manageable steps

Review Changes

Always review and test agent-suggested modifications

Maintain Context

Keep project notes updated for better agent performance
