Explain Code Errors on Mac with AI

Debugging is one of the most time-consuming parts of software development, and understanding error messages is often the biggest bottleneck. The Explain Error command in Echoo turns cryptic error messages and stack traces into clear, actionable explanations.

Select the complete error output for the best results. Copy the full stack trace including the error type, message, and file paths rather than just the error message line. AI models produce significantly more helpful explanations when they can trace the call stack and identify which files and functions are involved. If the error spans multiple lines in your terminal, select all of them.

Use the popup output mode for error explanations. Unlike grammar or tone commands where inline replacement makes sense, error explanations are informational and you want to read them alongside the original error. The popup lets you see the explanation while keeping the error visible in your terminal or IDE for reference.

Create specialized error explanation commands for your stack. A generic Explain Error command works well across languages, but a "Explain React Error" command that knows about common React pitfalls, hooks rules, and rendering lifecycle will give more targeted advice. Similarly, "Explain Python Error" with knowledge of common Python gotchas like indentation, import paths, and virtual environments provides more relevant fixes.

Choose AI providers with strong coding capabilities. Anthropic Claude and OpenAI GPT models excel at understanding code errors across all major languages. DeepSeek is particularly strong for programming tasks and cost-effective. For proprietary codebases where you cannot share error context externally, use Ollama with CodeLlama or a similar code-focused model.

Build error explanation into your debugging workflow. When you hit an error, select it immediately and press your shortcut instead of copying it to a browser search. The AI explanation often provides a direct fix, saving the time of reading through Stack Overflow threads. For recurring errors in your project, the explanation can help you understand the root cause and prevent similar issues in the future.
