How do I use the error explainer?
Paste the error (ideally with code context), pick a language, generate — the tool explains the cause, offers fixes and example code.
Which languages are supported?
Python, JavaScript, Go, Java, C++ and more, with auto-detection of the error source.
Does it provide fix code?
Yes — reference code per cause, explaining what to change and why.
Is error explanation free?
Yes — powered by DeepSeek, no registration, no limits.
What is it best for?
Daily debugging, learning to understand errors, onboarding legacy code and triaging third-party library issues.
What if information is insufficient?
The tool states what is missing (full stack, code snippet) and guides you to add it.
Is code saved?
No. Used only for this generation; not stored or trained on.
Does it explain English errors?
Yes — English errors get Chinese explanations with technical terms kept in English for documentation matching.
