Type a normal question rather than guessing exact keyword phrasing, and the extension interprets your intent before answering.
One popup covers the official documentation for Angular, React, Next.js, NestJS and Kubernetes, so you do not need a separate helper per stack.
Responses are sourced from the projects' official documentation, which keeps guidance aligned with the current documented behaviour.
The extension is a small download (about 75 KiB) that lives in the toolbar and stays out of the way until you need it.
