Cuelio — Transcript Search & AI for YouTube™

Find moments in YouTube™ videos with transcript search, AI answers, and one-click timestamp jumps.

Cuelio is a YouTube™ transcript search and AI assistant that helps you find exact moments inside videos. Use Cuelio to search YouTube transcripts, ask AI questions about a video, find timestamped answers, search YouTube comments, and jump directly to the right moment. Instead of watching an entire video again, open Cuelio and search for the word, phrase, quote, topic, or question you need. Key features: • YouTube transcript search Search inside video transcripts and captions directly on the YouTube page. Find quotes, topics, product details, tutorial steps, definitions, mentions, and key moments. • Timestamped search results Every transcript line includes a timestamp, so you can move from search result to video moment instantly. • AI answers for YouTube videos Ask AI about the current video and get answers grounded in the transcript. Cuelio shows source timestamps so you can verify and jump to the relevant parts. • YouTube comment search Search comments to understand what viewers are asking, liking, criticizing, or discussing. Useful for creators, marketers, researchers, and product teams. • Save and organize videos Keep important videos in your Cuelio library. With Premium, your library syncs across browsers and devices, and you can organize it with custom categories and tags — pick colors, filter, and find anything fast. • Multilingual workflow Use Cuelio with multiple interface languages and available YouTube captions/transcripts. Cuelio Premium Premium gives you real qualitative upgrades, not just a higher limit: • Saved AI chat history — your cuelioAI conversations are saved per video and come back automatically when you return to it. • Smarter AI model — Premium answers use a stronger model for sharper, better-grounded responses. • Synced saved-video library — your saved videos and tags follow you across browsers and devices. • Custom categories & tags — organize saved videos with your own color-coded labels and filters. • Higher daily limit — up to 700 cuelioAI questions per day, plus priority support.
