AI for Code Comments (2026)

Code comments improve maintainability when they explain WHY non-obvious code exists, but writing them takes discipline most engineers skip. AI code assistants now generate comments inline as engineers ship code, focusing on intent and context rather than restating what the code does. Cursor and GitHub Copilot lead AI code assistants with strong comment generation; Aider focuses on terminal-driven AI coding with comment support; Codeium and Tabnine target lighter-weight AI completion with comment generation.

Frequently asked

What makes a strong code comment?
Explains WHY, not WHAT. The code already shows what it does; a comment should explain non-obvious context (a workaround for a specific bug, a hidden invariant, a decision rationale). Comments restating what the code does add noise rather than signal.
Cursor vs Copilot for comments?
Cursor has stronger context-aware comment generation that sees the full file or repository; Copilot generates from local cursor context. Repository-wide comment consistency picks Cursor; per-line lightweight comments pick Copilot.
Should every function have a comment?
No. Well-named functions and obvious code do not need comments. Comments belong on: hidden constraints, subtle invariants, workarounds for specific bugs, and behavior that would surprise a reader. Comment density is not a quality signal.
