Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.

Ask Angular, React, Next.js, NestJS and Kubernetes docs questions in plain English
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.
