Developers are turning to GitHub Copilot, a ChatGPT-like tool that helps them write code. One startup VP says it helped him save 10% of the time he'd spend coding.

• GitHub Copilot, launched in 2021, uses generative AI to help programmers write code.
• The technology was created by OpenAI, the Microsoft-backed creator of ChatGPT.
• Programmers say it's led to big productivity gains, but domain knowledge is still necessary.

While ChatGPT has spurred a lot of excitement around artificial intelligence, the conversational chatbot is not the only technology to come from OpenAI.

The Microsoft-backed company has developed a slew of generative-AI products, including one called Codex that's already helping engineers become more productive.
