The most capable model is useless if it adds friction to your workflow. Tools like Cursor embed AI at the editor level; tools like Codeium and Copilot run as plugins on top of your existing environment. Start with what works in the editor you already use before evaluating output quality.
Some tools work only on the open file; others can index your entire codebase and answer questions across it. For solo projects, per-file context is often enough. For large codebases or multi-file refactors, codebase-aware tools like Cursor or Copilot Workspace close the gap significantly.
No current tool eliminates the need for code review. AI suggestions introduce bugs at the same rate they prevent them if accepted uncritically. The productivity gain comes from moving faster on boilerplate and standard patterns — not from removing judgment.
