1. What Is ChatGPT?
ChatGPT is a conversational AI developed by OpenAI, designed to simulate human-like dialogue. It can:
- Answer questions
- Write essays, emails, and stories
- Summarize documents
- Assist with research or brainstorming
It’s available as a web app, a mobile app, and even integrates into tools like Microsoft Word and Excel via “Copilot” branding.
2. What Is GitHub Copilot?
GitHub Copilot, a collaboration between GitHub and OpenAI, is an AI coding assistant. Its main features:
- Autocompletes code in real-time
- Suggests entire functions or code blocks
- Helps debug and improve code
- Supports multiple programming languages
It works as an extension inside popular code editors like Visual Studio Code.
3. What’s the Tech Behind Them?
Both tools are powered by versions of OpenAI’s large language models (LLMs), like GPT-3 or GPT-4. However:
- ChatGPT is general-purpose and fine-tuned for natural conversation across domains.
- Copilot is specialized for coding tasks, trained on public code from repositories like GitHub.
4. Key Differences at a Glance
