JetBrains is a software development tools company best known for its integrated development environments (IDEs) and developer productivity products such as IntelliJ IDEA, PyCharm, and TeamCity. It also builds collaboration and project management tools (e.g., YouTrack) and has expanded into AI-assisted coding through JetBrains AI and the AI Assistant integrated across its IDEs.
This is like giving your existing code to a very smart assistant and asking it to write the unit tests for you. The large language model reads the code, guesses what it should do, and then writes test cases to check that behavior automatically.
This is like having an AI pair‑programmer built into Visual Studio Code. As you type code or comments, it suggests whole lines or functions, helps you write boilerplate faster, and answers coding questions inside your editor.
Think of this as a smart co-pilot for programmers: it reads what you’re writing and the surrounding code, then suggests code, tests, and fixes—similar to autocorrect and autocomplete, but for entire software features.
Think of this as building ‘co-pilot’ assistants for programmers that can read and write code, help with designs, find bugs, and keep big software projects on track—like giving every developer a smart, tireless junior engineer who has read all your code and documentation.
