What they do

These assistants live inside the code editor, suggesting completions, entire functions, or explanations of unfamiliar code as a developer types, trained on massive public code corpora.

How they add value

Beyond autocomplete, the best tools understand the whole open project's context, letting suggestions match existing patterns, naming conventions, and architecture rather than generating generic boilerplate.

Where they fit

Most effective for well-specified, pattern-heavy code — CRUD endpoints, test scaffolding, boilerplate — with a human reviewing anything touching business logic or security-sensitive paths.
