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.

A ChatGPT-powered assistant for desktop and web that stays one hotkey away
Run ReadyRunner on macOS and Windows, or in the browser, and reach it instantly from anywhere with a configurable global hotkey so you don't break your flow.
Attach long or complex documents and ask questions about them. The assistant scans the file, answers from its contents and lets you jump to the relevant passages.
An editable text or code pane sits beside the chat. Ask for edits, explanations or fixes and collaborate on the content in place, including code.
Build reusable prompts for translation, summarizing, coding, debugging or personas, and apply them as system messages that shape every reply.
