GitHub Copilot is an AI-powered developer tool that's tightly integrated with GitHub to provide context-aware help at every stage of coding. It can help with code completion, turn natural language prompts into code completions, and even offer chat help to answer questions about codebases. It works with multiple IDEs and terminals and can help developers write better code and avoid security problems.
Another top contender is Sourcegraph, a code intelligence platform that offers an AI-powered coding assistant, code search, batch changes and code insights. It can navigate code across multiple repositories and can be run in the cloud or self-hosted. The service can help developers understand and navigate large codebases better, and is useful for development teams.
If you want something more interactive, Devv and Devv AI are AI-powered search engines that can give you quick answers to programming questions. Devv and Devv AI both have GitHub Mode (in beta) that lets you search and get help in the context of GitHub repositories, so you can debug and understand your code more quickly. The tools are designed to free developers from tedious busywork.
Last, Autopilot is tightly integrated with GitHub to help you write code more productively with chat help while you're coding, bug fixes and pull request reviews. It works with multiple programming languages and can handle large projects, so it's a good option for developers who want to get more out of their coding work and work more collaboratively.
