This table shows the main good points and things to think about for each AI tool. Things like easy setup, smart helpers, clear costs, and good safety features are what we like to see. But, needing to pay for full access, not much help from other users, and not enough safety info are things to keep in mind. This can help you figure out which tool might work best for you.

Personal Experiences and Community Feedback

Developers have found these AI tools useful in different ways, but they also ran into some issues.

Stepsize AI

Many developers liked that Stepsize AI explained its code suggestions, which helped them learn:

"Learning Python is new to me, so it was great that Stepsize showed me why it suggested changing my code a certain way."

But, some felt the free version didn't offer enough:

"I liked using Stepsize AI in VS Code, but I quickly ran into limits with the free version."

Cody AI

Cody AI users really appreciated its support for various languages:

"Our projects use different languages and frameworks. It's so helpful to have one AI tool that can handle all of them."

Yet, the lack of a user community was a downside:

"I wish Cody AI had a place where users could talk to each other, not just docs and email support."


Many liked how easy Tabnine was to use:

"Installing the Tabnine plugin for VS Code was easy. It started making good suggestions right away."

However, some wanted more features in the free version:

"I found the free version of Tabnine too restrictive because I couldn't customize it. I ended up paying for more control."

Mutable AI

Developers praised Mutable AI for understanding how code pieces work together:

"Mutable AI has been great for safely making big changes by understanding how everything connects across files."

But, its higher price was a concern for some:

"Mutable AI sounds smart, but $25 a month is a lot when there are cheaper or free tools available."

Codium AI

Many loved Codium's help with writing tests:

"I don't like writing tests, so having Codium do it for me has been amazing!"

But, they wanted it to support more programming languages:

"Codium AI is great, but I wished it worked with Java and C# too, not just Python and JavaScript."

Mintlify Writer

Developers found Mintlify Writer's automatic documentation creation very helpful:

"Updating docs has always been tough. Mintlify making them from our code automatically has been a big help."

However, some were worried about security:

"Mintlify Writer is useful, but I'd like more information on their security measures and encryption."

Based on what developers say, these AI tools are promising. But, they could be better in areas like language support, cost, security details, and having places for users to talk to each other.


Future Outlook

As AI keeps getting better, it's going to help developers do their job even faster and better. Here's what we might see happening in the next few years:

More Programming Languages and Frameworks

Right now, AI tools can handle popular languages like Python and JavaScript. Soon, they'll also work with other languages like C++ and Rust, and they'll get better at working with the tools developers use to build apps and websites.

Deeper Understanding of Code

AI is learning to really "get" what code is about, not just guessing based on patterns. This means it can give better advice on how to make your code work better and be easier to manage, covering more of your project.

Tighter Editor Integration

AI coding helpers are going to feel even more like a part of the tools you use every day, like VS Code or PyCharm. They'll fit into your coding process so smoothly, it'll be like they were always there.

Customization for Teams and Companies

Big teams have specific needs, so AI tools will let them set things up just right for their projects and security. This will help keep everyone on the same page.

Responsible and Ethical AI Practices

As AI works with more important code and data, the tools will focus more on being open and fair, and using data responsibly. This will help people trust them more.

Code Generation and Completion

These tools will get even better at writing whole sections of code for you, like files or tests. You'll still need to check their work, but they'll make starting new parts of your project quicker.

Tighter Integration with Project Management

AI tools will work more closely with tools like JIRA, GitHub, Slack, and Figma. This means keeping track of tasks, code changes, and team communication will be easier, all through your project.

AI is really changing how we write, check, and manage code. With these new tools coming, developers have a lot to look forward to!


The AI tools we talked about are really changing how people make software. These tools help programmers write, check, and handle code way faster than before.

From our comparison, tools like Stepsize AI, Cody AI, and Tabnine are user-friendly and work well with the tools programmers already use. They support popular programming languages like Python and JavaScript, and there are plans to include more. Features that stand out include giving reasons for code suggestions, working with multiple files at once, and automatically creating documentation, all of which save programmers a lot of time.

Most of these tools offer a free version, and the paid plans usually start at about $10 a month for one person. The level of support you get can vary, from lots to not so much, and the same goes for security. Some tools are more open about how they keep your code safe than others.

Programmers have found these tools very helpful for learning new things quickly and making their work faster. However, there are some downsides like limited language support, certain features being locked behind payment, concerns about security, and a lack of places for users to talk to each other.

Looking ahead, we expect these tools to get even better at working with project management tools, offer plans tailored for businesses, follow more responsible AI practices, and give even smarter code suggestions.

It's a great time to be a programmer. As these AI coding helpers improve, programmers will be able to focus more on solving big problems and bringing creative ideas to life even quicker. Getting into these new tools is key for staying ahead in the field.

Which AI tool is best for software development?

MutableAI is a tool that helps software developers work faster and smarter. It connects with popular coding platforms like VS Code and GitHub. It can automatically complete your code as you type, help you write documentation, and suggest improvements to your code.

Which AI is better for coding?

Sourcegraph Cody is an AI helper for developers that makes coding faster and helps you understand your code better. Sourcegraph's main product helps you search through your code and keep track of changes across your project.

Will AI replace programmers by 2030?

It's not a simple yes or no answer. While AI is becoming more important in making products, it doesn't mean it will take over jobs from human programmers. According to McKinsey Global Institute, AI could actually create 9 million new jobs in the U.S. by 2030.

Will AI ever replace developers?

AI is a useful tool, but it's not going to take over the jobs of software engineers. AI is good at doing repetitive tasks, but it doesn't have the creativity, problem-solving abilities, or deep understanding of what users need that human software engineers have.
