About this tool
Turns any text into formatted comment blocks for several programming languages. Supports the most common styles (// single line, /* multi-line */, # hash, blocks with decorative borders). Useful for creating visual separators in code files, header banners, section markers, and inline documentation with consistent style.
How to use
- Write or paste the text to turn into a comment.
- Pick the language (JavaScript, Python, C, SQL, etc.).
- Select the block style (simple, bordered, with asterisks).
- Copy the result ready to paste into your code.
Frequently asked questions
- Which languages are supported?
- The most common ones: JavaScript, TypeScript, Python, Java, C, C++, C#, Go, Rust, Ruby, PHP, SQL, HTML, CSS, Bash. Each language uses its typical comment character or sequence (//, #, --, /* */). If the language you need isn't there, pick one with the same syntax.
- What are bordered blocks good for?
- Creating visual separators in long files, marking important sections or chapter headers. Good for making structure obvious when scrolling through a file, although some style guides discourage overuse. Use sparingly to avoid making code noisier than needed.
- Can I use this to generate JSDoc or docstrings?
- This tool generates simple visual blocks, not structured documentation. For JSDoc, Python docstrings, or Java/C# documentation comments, use the specific conventions of those languages (with tags like @param, @returns). This tool is for banners and separators, not typed documentation.
