Frequently Asked Questions
Quick answers to the most common questions about our 6 YouTube tools
QIs NoteLM really free? What's the catch?
Yes, all 6 YouTube tools are 100% free. Online tools (transcript generator, thumbnail downloader, comment extractor, channel analytics) require no signup. Chrome extensions use your own free Gemini API key from Google, which provides 1,500 free requests per day. No credit card ever required.
QHow do I get a YouTube transcript from any video?
Use our YouTube Transcript Generator: 1) Paste the video URL, 2) Click "Generate", 3) Select language (100+ available), 4) Download in SRT, VTT, TXT, or other formats. Works with auto-generated and manual captions on any public YouTube video.
QWhy do I need a Gemini API key for the summarizer?
The API key enables direct communication with Google's Gemini AI from your browser. This keeps the service free (you use Google's free tier), protects your privacy (we never see your data), and removes any usage limits from our side. Get your free key at aistudio.google.com.
QWhat if a video doesn't have captions?
Transcript and summarizer tools require videos to have captions (CC). Most YouTube videos (95%+) have auto-generated captions. Check for the CC icon on the YouTube player. Thumbnail downloader and channel analytics work without captions.
QWhich browsers support the Chrome extensions?
Chrome extensions work on Chrome, Edge, Brave, Opera, and all Chromium-based browsers. Online tools work on any modern browser including Safari, Firefox, and mobile browsers. Firefox extension support is planned.
QHow is my data and privacy protected?
NoteLM processes everything locally in your browser. Your API key stays on your device and is never sent to our servers. We don't collect, store, or have access to any user data, browsing activity, or video information. All tools are open-source.
QCan I download YouTube thumbnails in high quality?
Yes! Our YouTube Thumbnail Downloader provides all available sizes including maxresdefault (1280×720), sddefault, hqdefault, and mqdefault. Simply paste the video URL and download your preferred size instantly.
QHow do I extract comments from a YouTube video?
Use our YouTube Comment Extractor: 1) Paste video URL, 2) Click "Load Comments", 3) Apply filters (top/newest, search, sentiment), 4) Export to JSON/CSV. Perfect for giveaways, sentiment analysis, and audience research.
