AI-powered research assistant and note-taking tool
Overview

Users can upload documents (PDFs, Google Docs), websites, YouTube videos, and audio files, then interact with their sources through an AI-powered chat interface. The tool generates summaries, extracts key insights, creates timelines, and produces study guides. Its standout Audio Overview feature converts source material into engaging podcast-style audio discussions between two AI hosts.
