Cuelio is a browser extension designed to enhance the process of searching and analyzing YouTube videos by making transcripts, comments, and precise timestamps easily accessible and searchable. It addresses the challenge of extracting specific information from lengthy or content-rich videos, allowing users to find exact lines, ask questions about the video content, and jump directly to relevant moments without the need to watch or scroll through the entire video.
The tool integrates directly with YouTube and is available for Chrome, Firefox (in beta), and Safari browsers. Its core features include transcript search, AI-powered answers tied to transcript evidence and timestamps, and comment search. Users can search video transcripts by keyword, phrase, quote, or topic, with results showing context around each match. The extension also enables searching through YouTube comments to identify repeated questions, complaints, recommendations, and product mentions, all without manual scrolling. Cuelio's AI component allows users to ask questions about the current video, providing answers that reference specific transcript segments and supporting timestamps for easy navigation. Additional features include switching between manual, auto, or translated caption tracks when available, copying useful lines, saving videos for future reference, and moving transcript snippets into personal workflows.
Cuelio is intended for a diverse audience, including students, developers, researchers, creators, marketers, and product teams. It is particularly useful when videos are too detailed or lengthy to skim, making it easier to pinpoint definitions, commands, claims, or viewer reactions quickly. The extension is designed with a local-first workflow, ensuring that search actions remain within the browser unless users choose to export data or use AI features explicitly.
By turning YouTube videos into a searchable research layer beside the video player, Cuelio streamlines the process of finding, referencing, and organizing key information from video content and its associated comments.
