Devin is an AI software engineer made by Cognition that can take on coding tasks by itself, writing, running and testing code.
In plain words
Rather than suggesting code for you to paste, Devin works through a task on its own. It has its own shell, code editor and web browser, so it can run commands, edit files and try out the web apps it builds. You can watch each step and take over in its editor at any point. Teams often hand it tasks from a Slack or Teams thread. Its makers say a job you could finish in about three hours is usually within its reach.
A quick example
Imagine coworkers are discussing a bug in a Slack thread. One of them tags Devin. It reads the code, reproduces the bug, makes a fix and runs the tests, while the team can check its progress and step in if needed.
Where you'll meet it
- Clearing a backlog of well-defined engineering tasks.
- Fixing bugs reported in team chat.
