A
About
ExplainDev is an AI-assisted coding companion designed to help developers quickly understand code they didn't write. By leveraging large language models, ExplainDev can analyze code snippets and generate clear, plain-English explanations—making it easier for developers to onboard onto new projects, learn unfamiliar frameworks, or debug complex logic. The tool integrates directly into developer workflows via a Chrome extension and a VS Code extension, enabling inline explanations without leaving the development environment. Users can highlight any piece of code or documentation and receive a contextual explanation within seconds. ExplainDev is particularly useful for junior developers trying to level up their skills, senior developers navigating legacy codebases, and anyone working with third-party libraries or open-source code. It supports multiple programming languages and adapts its explanations to the complexity of the selected code. Beyond simple explanations, ExplainDev can answer follow-up questions about a snippet, helping users develop a deeper understanding of the underlying logic and patterns.
