Software developers have to keep track of a lot of information at once. While deciding the best way to approach a problem and develop software, they must remember which lines of code they’ve already used, keep code straight, and never forget to close a parenthesis or bracket. 

AI coding tools simplify this process by reducing human error and keeping track of coding grammar and functions. This frees software developers to spend more of their time on the creative aspects of coding rather than the foundational nuances of it. By reducing human error, auto-completing source codes, or writing functional codes that get software developers started on a project, coding AI technology improves the efficiency and accuracy of the software development process. 

Here’s what you need to know about using AI tools for coding in 2023. 

What Are AI Coding Tools? 

AI coding tools, also known as AI coding assistants or no-code AI tools, help software developers write, edit, and refine code. 

AI coding tools are designed to improve coding generation efficiency and accuracy. Developers can use AI-generated code to pull codes together more quickly while reducing human error. 

Keep in mind that AI coding tools are just that — tools. They are designed to assist skilled software developers, not to replace developers in the workplace. AI coding tools don’t have the creativity, flexibility, or human understanding needed to create ethical and functional software from scratch. But by using artificial intelligence coding alongside a skilled software developer, you can produce improved software faster than if you used a developer’s skills alone. 

How AI Helps Coders

There are two major types of AI coding tools: tools that write secure code for developers based on developers’ prompts or tools that auto-suggest how to complete a line of code in real-time based on what the developer has already written. Both types of tools are designed to help developers achieve existing goals. 

Coding AI tools are not intended to come up with the vision for software, and they’re not designed to understand the nuance of everything a company needs software to do. They’re designed to automate coding as much as possible so developers have more time to think of the best way to accomplish more nuanced tasks while sticking to a deadline.

Below are the top 11 best AI coding tools to help developers write better code in 2023.

1. Copilot (GitHub)

Although GitHub Copilot is built on top of one of the more popular free no-code AI tools, OpenAI Codex (which we’ll talk about in-depth later in this article), Copilot expands those existing features to support more programming languages and generate more complex code than you could ever dream of doing with OpenAI Codex alone. 

Copilot is one of the no-code AI tools on this list, which means your developer types a prompt in English, and Copilot generates code in many different programming languages. By reducing the time it takes your programmers to develop simple, repetitive code patterns, Copilot allows them to spend more time building the robust software that code fits into. 

Key Features

Users describe Copilot as being hard to train initially but useful long term. It’s known for understanding multiple written languages and churning code in multiple programming languages, making it adaptable for most companies. 

Some of Copilot’s key features include the following:

  • Detects errors in existing codes and recommends fixes
  • Writes original code based on natural language prompts in more than a dozen large language models
  • Can write code in numerous programming languages, including C++, Python, Javascript, TypeScript, and Go
  • Integrates with several different code editors, including Neovim, Visual Studio Code, and JetBrains IDEs

2. Tabnine

Tabnine is a code completion tool designed to help software developers improve their flow and efficiency. It works like autocomplete on a cell phone; based on the developer’s syntax, Tabnine predicts and suggests the rest of a line of code. If the line looks right to the developer, it only takes one click to accept the suggestion, and the developer can begin typing the following line of code. 

Although Tabnine uses a lot of storage to run, it can significantly speed up the software development process. But Tabnine can also help by reducing coding errors. Software developers are much less likely to forget a closing bracket or parenthesis, with Tabnine software actively reminding them to finish their line of code. 

Key Features

Tabnine has been noted as not always being accurate. Like with text message autofill suggestions, it can’t read a developer’s mind every time. But it simplifies code production, especially for simple or redundant codes, reduces human error, and reduces a team’s overall tech debt. 

Key features of Tabnine include the following:

  • Makes accurate code suggestions as code is being typed, reducing the amount of time software developers have to spend writing each line of code 
  • Identifies potential errors in code and suggests fixes for those errors in real-time
  • Designed to fit different security protocols, and can be run from regular laptops, firewall-protected servers, or even the cloud
  • Supports numerous programming languages, including JavaScript, TypeScript, Python, Go, Rush, and Bash

3. Codiga

Codiga is an AI coding tool focused on reducing technology debt by reviewing existing code and helping your team clean it up. While it can write short snippets of fresh AI-powered code, Codiga’s main focus is simplifying the code refactoring process.

Codiga locates coding errors and automatically fixes those errors. But it also takes code review a step further by helping teach and enforce high-quality code review rules across your entire team. 

Key Features

Codiga stands out as an AI coding tool focused on improving both coding accuracy and security. For teams looking to improve overall software security, Codiga is a smart AI choice.

4. Replit Ghostwriter

Ghostwriter is a generative AI tool designed to learn from your team as you work and automate tasks, freeing your team up to do more creative work behind the scenes. 

The chatbot not only translates natural language into lines of code but can also take snippets of code and explain it in basic language. For teams of programmers, this makes it easier to catch up on what another team member was doing and build off of their work. Voice-to-code features allow developers to brainstorm projects on the go. 

Key Features

Replit Ghostwriter is great for companies that don’t already have their own integrated development environment (IDE) and are looking to take on a new AI and IDE simultaneously. Although it only works with Replit, it has a high level of functionality. 

Replit Ghostwriter’s key features include the following:

  • Fast response time allows developers to work quickly on new projects
  • Translates natural language into code and translates code back into natural language
  • Supports sixteen different programming languages, although it’s most effective in Python and JavaScript
  • The brainstorming feature helps with creative projects

5. Sourcegraph Cody

For developers working as a team, Sourcegraph Cody provides support to help different developers continue improving one another’s work. Its code-based assistant provides context-specific information about where code lives and who has updated that code. 

Sourcegraph Cody also helps individual developers locate precise code, develop new functions, and explain the details of existing code. This makes Sourcegraph Cody an invaluable tool for seasoned developers and a great resource for helping get new developers up to speed quickly. 

Key Features

Although Sourcegraph is one of the more expensive AI coding solutions, that high price point comes with a robust suite of features to help developers as individuals and as teams. 

Some of these features include the following:
