Debugging code—especially in the context of AI and modern development workflows—has become
much more powerful and efficient thanks to advanced AI-powered tools like GitHub Copilot,
ChatGPT, and Perplexity AI. Here’s an expert overview of how these tools work, what makes
them unique, and how developers can leverage them for debugging tasks.
1. GitHub Copilot
What It Is:
GitHub Copilot is an AI-powered coding assistant that integrates directly into popular code editors like
Visual Studio Code. It can suggest entire lines, functions, or even debug solutions as you type, making
it especially helpful during the debugging process.
Debugging Features:
In-Editor Debugging: Copilot detects bugs in real time and provides smart code suggestions or potential fixes directly in your code editor.
Copilot Chat: An interactive AI chatbot within VS Code or Visual Studio allows natural language debugging. You can ask Copilot Chat questions like “Why is this function failing?” or “How do I fix this error?” and get targeted explanations and solutions.
Configure Debug Settings: Copilot assists in setting up debugging configurations (such as launch.json for node apps or Python), helping you quickly prepare your project for step-through debugging.
Error Explanations: It explains exceptions, call stacks, and provides remediation steps tailored to your current context.
Who Should Use:
Any developer seeking to automate repetitive debugging tasks, streamline error triage, and resolve bugs directly in their IDE.
2. ChatGPT
What It Is:
ChatGPT, developed by OpenAI, is an AI conversational agent trained on a massive corpus of code
and natural language. It’s available as a web tool and via plugins in some IDEs.
Debugging Features:
Error Detection: Paste your code (or error messages), and ChatGPT can spot syntax errors, typos, and logical bugs. It highlights faulty lines and explains what went wrong.
Problem Isolation: Helps you break down complex problems, guides you through step-by-step reproduction, and isolates which part of your code is causing errors.
Code Optimization: Offers suggestions for more efficient or robust implementations— sometimes even explaining best practices or alternative approaches.
Learning Opportunity: By asking clarifying questions, ChatGPT helps you reason about your code and learn new debugging techniques as you go.
Who Should Use:
Ideal for both beginners and experienced coders who want an always-available “debugging buddy”
that can explain, troubleshoot, and teach.
3. Perplexity AI
What It Is:
Perplexity AI is an “answer engine” that combines real-time web data with powerful AI models
(like GPT-4, Claude, and others). It’s increasingly used by developers to research obscure errors,
debug issues, and automate technical problem solving.
Debugging Features:
Live Error Research: Perplexity can analyze error messages or code snippets, search the latest resources on the web, and synthesize solutions based on up-to-the-minute information.
Code Analysis & Explanation: Can provide step-by-step analysis, debugging suggestions, and explanations for why errors are occurring, drawing from documentation, forums, and advanced models.
Model Flexibility: Lets you switch between models (GPT-4, Claude, Gemini, etc.) to get different perspectives or more accurate answers for your debugging needs.
Real-World Workflows: Developers use Perplexity for comparing frameworks, troubleshooting APIs, and quickly finding fixes without browsing multiple tabs— streamlining the debugging journey.
Who Should Use:
Developers who want in-depth, up-to-date debugging guidance sourced from both AI and live technical
resources—perfect for tackling tricky or current edge cases.

Other Noteworthy AI Debugging Tools
While Copilot, ChatGPT, and Perplexity are leading the wave, other tools like SnykCode (real-time bug detection), CodeRabbit AI (code reviews), and Qodo AI (test generation) are also popular for specialized debugging tasks.
Best Practices
Use Copilot when you want seamless, code-aware suggestions and debugging inside your IDE.
Use ChatGPT for exploratory debugging, code reviews, or when you want to learn about common mistakes or best practices.
Use Perplexity AI when you need fast research, multi-model analysis, or web-based troubleshooting help leveraging the latest information.
