Updated on | Sign up for learn to code tips


The past couple of years have truly felt like the beginning of the AI renaissance. Along with the general influx of AI tools for purposes like art and writing, there has been an explosion of AI that can write code.

These AI coding tools aim to enhance the productivity and efficiency of developers, providing assistance in various aspects of the coding process.

Programs that focus on AI for code generation are often able to complete your code or write new lines for you to eliminate busywork.

And in addition to AI that codes for you, there are also AI coding assistants that can help you learn to code yourself.

But since there are a growing number of AI-assisted coding tools out there now, how do you pick the best AI for coding based on your needs?

In this article, we’ve rounded up a list of 19 of the best AI coding tools and assistants you may want to try—and given you a quick overview of the most popular ones—so you can decide which is best for you.

Let’s learn about the best AI to write code!

What Are AI Coding Tools?

First things first: what does it take for a tool to qualify as an AI coding assistant? Essentially, by “AI coding tools” we mean AI that codes for you or helps you write code in some way.

For instance, it might:

  • 💻 Generate the code for you
  • 🤖 Autocomplete your code
  • 📝 Give you advice, instructions, or feedback
  • Etc.

The best coding AI tools often provide features such as code completion, error detection, code suggestion, and sometimes even automated code generation. 

Having an AI coding assistant can also be like coding with a tutor or another programmer by your side. If you’re using a tool like ChatGPT for programming, you can ask it specific questions to help you solve problems or get unstuck. They can also introduce you to common coding patterns and help you learn new programming languages.

Jeff W. tweets: “It has been good for learning new languages too because it can so patiently deep dive on things you need further explanation of, 100% personalized and in context.”

Daniel Kuntz shared how he believes AI-assisted coding helps programmers grow and develop their skills, despite frequent misconceptions to the contrary. “‘AI coding tools make you a bad engineer’ No, they actually help you learn faster by dramatically shortening the trial and error feedback loop.”

Ultimately, instead of thinking of it as AI that writes code for you, try to reposition it as AI that writes code with you. You’ll still need the right skills and knowledge to use them successfully!

1. GitHub Copilot

What is Copilot? This popular AI coding assistant, advertised as “your AI pair programmer,” basically acts as an autocomplete tool. In function, it’s kind of like when Gmail suggests the rest of your sentence and you can accept it or not.

Created by Microsoft-backed OpenAI, GitHub Copilot may possibly be the most well-known AI tool specifically for coding. Visual Studio Code users can also use it as a VSCode copilot through an extension.

GitHub Copilot

💰 Price: $10/month or $100/year for an individual plan.

Is GitHub Copilot free in any cases? Yes: it’s free for verified students, teachers, and maintainers of popular open source software. Plus, everyone can sign up for a free trial to see if they like the AI Copilot first.

🤔 When & how to use it: As programmers write code, GitHub Copilot provides intelligent code suggestions in real-time.

It predicts entire lines or blocks of code based on the context of what you’re writing. It can see all the code in your project, so it knows (for example) if you’re using React components or TypeScript, etc.

It learns from context and can translate developers’ instructions from natural language comments into code.

Copilot AI can be an especially great shortcut for writing repetitive or boilerplate code, since it learns from how you use it.

🗣️ What do real coders say? 

  • Many coders say they use ChatGPT-4 in conjunction with Copilot.
  • This Redditor says: “It’s also very good at explaining how code works and writes awesome commentary on functions, variables, etc. Right now you still have to guide it and do the backbone of the programming, but if you hit a snag when debugging or want some more common algorithms, boilerplate code, etc – it’s awesome at writing them for you.”

This is one of the most popular AI coding tools among real coders.

Cursor

💰 Price: Free, or an upgraded version for $20/month

🤔 When & how to use it: You can chat with your project, make code changes, spot and fix bugs, and a lot more.

🗣️ What do real coders say? 

  • This Redditor says: “Not only can you feed it the entire code base, you can reference document links that it will pull from when generating code. Take NiceGUI for example which was created after sept first. Type @, select new doc, paste the link, and now the model knows NiceGUI. Seriously, try it.” 
  • This Redditor: “Same; been using Cursor for a short month maybe, VERY pleased. It’s not perfect, and a few minor UI issues are annoying, but the over-all product is miles ahead of anything I’ve ever used before.”

4. Aider

Another fan favorite among real coders, Aider is a ChatGPT-powered coding tool that lives in your terminal. You can even AI pair program with it, using just your voice.

It can read one or multiple files of your codebase and can edit them and git commit with the changes in your prompt.

Aider

💰 Price: Free

🤔 When & how to use it: It allows you to edit code stored in your local git repository. Aider is unique in that it lets you ask for changes to pre-existing, larger codebases.

🗣️ What do real coders say? 

  • According to this Redditor: “Open source, ability to work with your local repo, fantastic user experience. After using a handful of commercial coding assistants with zero luck at getting actually usable code, aider instantly worked for me.”
  • This Redditor says: “Aider is the best one I have used so far. With GPT4 the code is correct 90% of the time and plenty fast. Yes it is a terminal application, but it is smarter than Cursor or any of the other ones I have tried. I find myself using a combination of aider to write major blocks of code and Cursor to fix minor things.”
  • Twitter user Rupert Rebentisch: “Aider, a GPT-based command-line coding assistant, is my new favorite tool. It’s like having a personal coding tutor available 24/7.”
