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.

Drag any text on a page and ask ChatGPT about it instantly
Highlight text on any webpage and a button appears; one click sends the selection to ChatGPT and shows the answer in place.
Save favorite prompts as preset slots and switch between them for different tasks, with per-slot temperature control.
Open a compact chat window from the extension popup to converse with the model without leaving your current page.
Choose between gpt-3.5-turbo, gpt-4o, gpt-4o-mini and gpt-4-turbo as the default model.
