How do I use the code comment tool?
Paste code (note the language), generate annotated output with line and doc comments plus key-comment notes.
What is the comment style?
Line comments for key logic, JSDoc/docstring for functions — explaining the "why", not restating the code.
Are pitfalls flagged?
Yes — edge cases, null risks and performance issues are noted in comments.
Is comment generation free?
Yes — powered by DeepSeek, no registration, no limits.
Which languages are supported?
Python, JavaScript, TypeScript, Go, Java, C++ and more, with matching comment conventions.
What is it best for?
Legacy code onboarding, code review, teaching examples, team documentation and interview walkthroughs.
Is code saved?
No. Used only for this generation; not stored or trained on.
Can comments be in Chinese or English?
Yes — specify the language; defaults to the input language.
