What is an AI code assistant?
An AI code assistant is a developer tool that reads your codebase and helps you write, explain, and fix code using a large language model trained on billions of lines of source. It suggests completions as you type, answers questions in a chat pane, and can run multi-step edits across files on its own. They range from IDE plugins like GitHub Copilot to standalone AI editors like Cursor and terminal-based coding agents.
What AI code assistants do
- Inline autocomplete that predicts the next lines as you type
- Chat pane that explains, reviews, and debugs your code
- Multi-file edits and refactors from a plain-English prompt
- Agent mode that plans, edits, and runs commands autonomously
- Context from your repo, open files, and terminal errors
- Works in VS Code, JetBrains, Neovim, or the terminal
Who uses AI code assistants
01
Individual developers
Speed up daily coding with autocomplete and quick answers without leaving the editor.
02
Teams and enterprises
Adopt shared assistants with policy controls, private-code isolation, and seat management.
03
Learners and beginners
Understand unfamiliar code, get explanations, and pick up a new language or framework.
04
Full-project agentic builds
Hand off whole features or migrations to an agent that edits and tests across many files.
How AI code assistants work
Code assistants send your current file, nearby code, and the prompt to a model trained on public and licensed source code, which predicts the completion or edit token by token. Retrieval pulls in relevant snippets from the rest of your repository so suggestions match your own APIs and style. Agentic tools add a loop where the model runs commands, reads the output, and keeps editing until the task passes.
