Best 20+ AI Code Assistant to use in 2025

JetBrains AI is a set of AI-powered tools built directly into JetBrains development environments. It includes two main parts: AI Assistant and Junie.

Claude Code is a terminal-based AI assistant that understands your entire codebase and helps you code faster. You simply describe what you want in plain English, and it writes the code, makes changes across multiple files, and runs tests to verify everything works.

PearAI is an AI-powered code editor designed to make programming easier and faster. It is based on Visual Studio Code, so if you have used that editor before, PearAI will feel familiar. The main difference is that PearAI includes AI tools that understand your code and help you write better programs.

Forgecode is a lightweight AI pair programmer that lives in your terminal. Unlike heavy coding tools that require special setup, Forgecode works where you already code. You simply type commands or questions, and it helps you write, debug, review, and understand code.

Kilocode is a tool that brings AI assistance directly into your code editor. You can ask it to write code, fix problems, or explain things in plain language. It works as an extension for VS Code and other similar editors like Cursor and JetBrains.

CodeEdit is a native code editor for macOS that helps you write and edit code in any programming language. It is built to be lightweight yet powerful, similar to how Apple builds its own apps. Unlike editors like VS Code that run on Electron, CodeEdit uses native Mac technology for better speed and efficiency.

Roo Code is a smart coding helper that lives inside VS Code. Think of it as having multiple AI assistants working together on your code. One assistant can plan the structure of your app, another can write the actual code, and another can find and fix problems.

Tabby is an AI tool that helps you write code by giving smart suggestions in real time. You can install it on your own computer or server, and it connects to your favorite code editor. As you type code, Tabby predicts what you might write next and offers helpful suggestions.

Aider is a tool that lets you have conversations with AI about your code, right from your command line. You can ask it to add features, fix bugs, write tests, or improve your code structure. Unlike other AI tools, Aider edits your files directly and commits changes to Git for you.

Void is an AI-powered code editor that helps you write better code. You can type questions, and it gives you answers with code suggestions. Unlike other editors, Void does not store your code on someone else's server. Everything stays under your control.
