Alex

The Most Powerful AI Agent for Xcode

Free Trial

Description

Alex is an AI-powered assistant designed specifically for Xcode, enabling iOS developers to build projects, fix bugs, add Swift packages, and run apps in Simulator with ease. It streamlines the development workflow by delivering features such as AI-driven debugging, smart code completion, seamless code manipulation, and instant code search, while providing robust privacy by processing all sensitive data locally.

Supporting integration with both local and hosted AI models, Alex allows developers to automate repetitive tasks, generate Swift code from images, and quickly manage packages or commands without leaving the Xcode environment. None of your code or project data is collected or stored externally, ensuring a private and secure development experience optimized for speed and efficiency.

Frequently Asked Questions

How do chat credits work in Alex?

On paid plans, you receive a set number of chat credits each month, with each AI message or agent follow-up deducting one credit. You can purchase top-ups for additional messages, and top-ups roll over while monthly credits do not.

How is image generation billed in Alex?

Each generated image costs 2 chat credits, and every additional image increases the cost by one credit per image.

How does Alex protect my code and data?

Alex does not relay your code through external servers and allows you to use any OpenAI-compatible endpoint, including local models. All sensitive data, such as chat history and custom prompts, are stored locally and not collected or trained on.

Can I use my own AI models with Alex?

Yes, you can override the AI model endpoints in Alex to use your own compatible models, including local options for increased privacy.

Is there a device limit on Alex plans?

The Unlimited plan has a 1 device limit, while information about other plans’ device limits is not specified.
