One-click, delightfully brief AI summaries of any article, blog or PDF in your browser
Summarize any article, blog post or PDF report open in your browser with a single click, without copying text into another app.
Summaries are tuned to be brief and skimmable, giving you the key takeaway rather than a full rewrite of the page.
Built for faster gathering of background, market context and supporting stats for presentations, reports and proposals.
You connect your own OpenAI API key, so model choice and spend stay under your control instead of a fixed subscription.
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.
