Built for
Students, developers, researchers, creators, and product teams.
Cuelio works best when a video is too valuable to skim, too long to rewatch, and full of details you need to find again.
Students
Review lectures, find definitions, and jump back to the explanation that matters.
Developers
Search long coding tutorials, demos, and conference talks for the exact command, tool, or implementation detail.
Researchers
Extract claims, facts, quotes, and evidence from interviews, talks, demos, and podcasts.
Creators and marketers
Search comments, spot viewer reactions, and turn long videos into reusable research and content ideas.
Product teams
Turn videos and comments into product research, objections, feature requests, and audience language.
Privacy posture
Transcript work should feel close to the browser.
The core workflow is designed to run locally. Optional cuelioAI actions are explicit, source-bound, and easy to understand.
Read privacy notesNo account required
Cuelio does not require registration, login, or a user account. Core features — transcript search, comment search, saves, and history — run without identifying you.
What stays in your browser
Transcript data, cached video content, saved videos, search history, and settings are stored in local browser storage. They are never sent to our servers.
Anonymous install ID
Cuelio generates a random anonymous install ID stored in your browser. It is used to enforce daily cuelioAI usage limits. It is not linked to your name, email, or any personal account.
When you use cuelioAI
When you ask cuelioAI a question, relevant transcript excerpts and your question are sent to our AI proxy. Your install ID is included to track daily limits. No other data is sent.
Comments and YouTube data
Comment data is fetched from YouTube when you choose to load it and stays in your browser. If you enable comment context for cuelioAI, selected relevant excerpts may be included with your question.
Permissions requested
Cuelio requests storage (local data), scripting (to read video page context), and sidePanel (to open the side panel). No browsing history, location, camera, or microphone access is used.
Third-party AI provider
cuelioAI answers are powered by Google Gemini via our proxy server. Transcript excerpts sent for AI answers are processed by Google according to their privacy policy. We do not store your questions or answers on our servers.
Changes and contact
We may update this policy as Cuelio evolves. Questions about privacy can be directed to me@pean.dev.
Local-first default
Transcript search, timestamp jumps, and saved videos all run in-browser with no external calls.
Zero background AI
cuelioAI is triggered only by your explicit action — never in the background, never automatic.
Source-grounded answers
Every cuelioAI answer cites specific transcript timestamps so you can verify claims in the video.
AI by design
Built transparent from the start — how Cuelio handles data and AI.
Cuelio is local-first by default. No transcript leaves the browser until you explicitly ask cuelioAI a question or request a summary.
FAQ
Useful answers for people searching inside YouTube.
Short, direct answers for people looking for YouTube transcript search, comment search, exact timestamps, and AI answers with sources.
What does Cuelio do?
Cuelio helps you search YouTube transcripts and comments, ask cuelioAI questions about videos, and jump to exact moments from a Chrome side panel.
How do I search a YouTube transcript for a word or phrase?
Open a captioned YouTube video, then use Cuelio's transcript search to look for a keyword, phrase, quote, product name, or claim. Matches stay grouped with nearby context so you can tell which line matters before you click.
Can I find an exact quote in a YouTube video without scrubbing the timeline?
Yes. Cuelio is designed for exact-line retrieval: search the transcript, inspect the surrounding wording, and jump back to the exact timestamp when you find the right quote.
Can I search YouTube comments without endless scrolling?
Yes. Cuelio includes comment search so you can look for questions, complaints, recommendations, and product mentions across the thread much faster than scrolling by hand.
Can I ask AI questions about a YouTube video and keep sources?
Yes. cuelioAI answers are meant to stay grounded in the active transcript, with cited time ranges so you can verify the answer against the video.
Is Cuelio a YouTube transcript summarizer with timestamps?
Yes, but summary is not the whole product. Cuelio can generate transcript-based summaries and chapter-style recaps while keeping the workflow tied to visible transcript lines and clickable timestamps.
Does it work without captions?
The main workflow depends on captions or transcript tracks being available for the YouTube video.
Does Cuelio summarize every video automatically?
No. Summary and cuelioAI answer actions are user-started, so transcript text is not sent to an AI provider without your action.
Where are saved videos and settings stored?
The product is designed for local browser storage first, including settings, cached transcript state, saved videos, and history.
Can I jump to the exact part of a video?
Yes. Transcript rows, search results, citations, and answer sources are designed around clickable timecodes, so Cuelio also works like a YouTube timestamp finder.
Can I export transcript notes or chapter drafts?
Yes. Cuelio is built to help you move transcript snippets, quotes, notes, chapter outlines, and summary material into your own research or writing workflow.
Who is Cuelio for?
Students, researchers, creators, language learners, product teams, and anyone who needs to turn long videos into searchable source material.
Did anyone else miss the part where they explained the pricing change for new users?
@alexpm · repeated questionThe biggest issue is pricing confusion after the onboarding flow changes.
@growthmira · complaintHelpful reply: they answer the pricing question around minute three in the demo.
