About this tool
Good comments explain the intent behind code, not just what each line literally does. This tool reads a snippet and adds a single concise comment that captures why the code exists and what it accomplishes, the kind of note a reviewer actually finds useful. It deliberately avoids the noise of line-by-line narration that clutters a file without adding understanding. Paste a function or block you're about to commit and get back the same code with one comment worth keeping — a fast way to document work you understand now but future-you (or a teammate) won't.
Frequently asked questions
Does it comment every single line?+
No — it adds one focused comment explaining intent, rather than restating each line, which is what makes comments useful instead of noisy.
What languages does it work with?+
Any common language. It infers the comment syntax (//, #, /* */, etc.) from the snippet you paste in.
Will it change my code?+
No — it returns your code unchanged with a comment added. It won't refactor or rewrite the logic.
