Autocomplete used to guess the end of a variable name. Now it drafts a function, explains a stack trace, and refactors a file while you read the previous suggestion. The shift came from models trained on huge amounts of public code, wired directly into the editor. GitHub Copilot put the idea in front of millions, and Cursor, Claude, and a wave of others pushed it further. For most working developers the question is no longer whether to use one, but which part of the day it earns its keep.
Assistants, generators, and reviewers
The tools group by where they sit in your workflow. Code assistants live inside the editor and complete lines as you type, while code generators turn a plain-language request into a whole component. After the code exists, code review tools scan a pull request for bugs and style issues, and debugging helpers read the error and suggest the fix. Narrow jobs like SQL and test generation have their own specialists.
Where it helps and where it hurts
These tools shine on the parts of coding that are known and repetitive: boilerplate, glue code, first drafts of tests, and translating between languages. They struggle with system design, unfamiliar business rules, and anything where being subtly wrong is expensive. Treat generated code as a confident junior's first pass. It needs review for security holes, edge cases, and whether it even fits the wider codebase.
Reviewing what you did not write
The real risk is speed without understanding. Accepting a suggestion you cannot explain moves a bug from now to later, when it is harder to trace. Read every block before you commit it, keep tests honest, and lean on an AI agent for the multi-step chores rather than the judgment calls.
