Strategies for software developers to use AI tools for coding

AI-augmented software development is part of the natural evolution of computer science. While human intelligence is still key to a number of aspects of good-quality coding, the incorporation of AI can take your productivity and accuracy to a whole new level. 

Use generative AI tools to autocomplete your code

Integrated development environments have long been helping developers with suggestions based on their coding behavior, the language, and the codebase.  AI takes it much further by understanding natural language descriptions of code tasks using advanced language models. So, now AI-powered code editors can 

  • Complete your code as you type
  • Rectify typos and syntax errors
  • Generate code based on a certain task and context.

AI for codebase analysis

When you start working on a project built by other developers, you could end up spending days to fully understand the codebase. Now, with AI tools like Adrenaline in the equation, you can converse with the codebase as if it were a person with in-depth knowledge of the code.

Take advantage of AI code review tools

 Code reviews are tedious yet essential. With AI tools, you can automate the process of code reviews. Trained on large code repositories and millions of execution traces, these tools can help you find 

  • bugs
  • security vulnerabilities
  • scopes for optimization

In fact, there are tools that can predict bugs in your code. And then there are AI code refactoring tools that can help you automate code refactoring. 

Code migration with AI tools

Thanks to AI tools, code migration, and translation are almost instantaneous processes now. Developers can save hundreds of hours by deploying automated migration tools, hours that they’d otherwise lose converting millions of lines of legacy code into a modern, more efficient programming language. 

Testing tools powered by AI

Testing a software product comes with many challenges the peaks of them being tight deadlines and wrong test estimations. These issues can be easily circumnavigated with the help of AI. 

AI can help you generate and run tests, significantly increasing test coverage and reducing the possibility of introducing new bugs.

AI for developers but not for programming

There is more to software development than just writing code. As a software engineer, you need to communicate with clients, stakeholders, and business leaders to understand their specific requirements. Moreover, you need to create documentation for your code so that others can understand your strategies and pick up where you’ve left off without much hassle.  

So, you need

AI tools for meeting notes 

Tools that can transcribe and summarize meetings are for everyone but they can be especially useful for developers working in a large team where requests and requirements pour in from all directions.

AI tools for documentation 

It’s hard to find developers who love to document their code. Then again, it’s essential not only for other developers to understand your code, but also for the original coder to look back and make sense of their own code. Now, you have tools that can generate documentation suitable for multiple purposes – education, user guidelines, and manuals. 

11 AI tools every software developer should use in 2023

In this section, we will take a deeper look into ai tools for developers built for various purposes. We will start with the AI code completion tools and work our way through all the other categories.

The relevance of human developers in the presence of generative AI tools

Software developers build applications that will eventually be used by human beings (at least that’s the intention in most cases). It takes a human being to understand another. It is still difficult for AI to imagine every aspect of the user experience or to conjure up features out of the blue to bring novelty to a product. That’s why we have AI assistants to augment our work and not AI developers to steal it. 

Here’s what we bring to the table

  • Innovative thinking to find novel solutions to complex problems
  • Domain expertise to add nuance to a product built for a specific industry
  • Ethical decision-making to ensure that a piece of software doesn’t breach boundaries 
  • Complex problem-solving that goes beyond AI capabilities.

As a developer or an aspiring developer in 2023, it is very important that you adapt to the presence of generative Ai and make the best use of the best AI coding tools not only to ease up your work but also to learn and do more in shorter spans of time.
