Chat Based Code Explanation And Refactoring

via “codebase-aware conversational chat with file/symbol references”

AI-native code editor — Cursor Tab, Cmd+K editing, Chat with codebase, Composer multi-file.

Unique: Implements file/symbol awareness through explicit `@` reference syntax rather than automatic context detection, giving developers precise control over what code context is included in the query. Chat history is maintained in the editor UI, creating a persistent conversation thread tied to the project.

vs others: More codebase-aware than generic ChatGPT because it can reference specific files and understands the project structure, but less sophisticated than tools with semantic search indexing because the context mechanism is undocumented and may rely on simple file inclusion rather than semantic relevance.
