What is Stealth Sponsor and how does it compare to SponsorBlock?

Stealth Sponsor is a complete YouTube ad blocker plus AI-powered sponsor blocker. It strips YouTube's pre-roll, mid-roll and Shorts ads at the network level, blocks YouTube TV ads, bypasses Free with ads movies, and auto-detects in-video sponsor reads with AI transcript analysis. Unlike SponsorBlock which only relies on community submissions for sponsor segments, Stealth Sponsor instantly handles any video with AI, includes the SponsorBlock community database as a backup, and adds Picture-in-Picture, audio normalization, a full YouTube redesign called Stealth Theme, a YouTube downloader, playback speed unlock, and ad skipping on Tubi, Pluto TV, Prime Video, Peacock, Twitch and Facebook.

Does Stealth Sponsor block YouTube video ads?

Yes. Stealth Sponsor surgically strips YouTube's ad payload before the player ever schedules an ad - no flashing pre-roll, no mid-roll interruptions, no sponsored Shorts in the reel, no overlay banners. It uses the same proven technique as uBlock Origin and Brave Shields and works without a YouTube Premium subscription.

Does Stealth Sponsor work on YouTube TV and Free with ads movies?

Yes. Stealth Sponsor includes a dedicated YouTube TV ad skip that mutes and fast-forwards through ad breaks on live channels and on-demand. It also bypasses YouTube's Free with ads movies and TV shows by stripping the ad slots from the player payload and visually striking through the Free with ads tag.

Can Stealth Sponsor download YouTube videos?

Yes. Stealth Sponsor replaces YouTube's Premium-gated download dialog with a built-in quality picker that lets you save any video at any resolution YouTube exposes, including 4K and 8K. No Premium subscription is required. It works the same way yt-dlp and NewPipe do - the extension just talks to youtube.com and googlevideo.com and never loads remote code.

What is Stealth Theme for YouTube?

Stealth Theme is a full visual and structural redesign of YouTube. The Subscribe button moves into the masthead, like / share / save become floating overlays on the player, the related videos sidebar auto-collapses with a peek strip, and the comments section is rebuilt into clean cards with extra sort options (oldest, newest, most likes, most replies, plus a load-all-comments mode). Shorts shelves, merch shelves, sidebar ads and Premium upsells are hidden across the home feed, sidebar and search results.

Does Stealth Sponsor unlock YouTube playback speed and quality?

Yes. Stealth Sponsor adds 3x, 4x and custom playback speeds directly into YouTube's playback speed menu (YouTube normally gates 3x+ behind Premium) and includes an Auto Best Quality toggle that automatically selects the highest standard quality YouTube exposes for each video.

Is Stealth VPN Chrome extension free?

Stealth VPN Chrome has both free and premium features. Free features include ad blocking, tracker blocking, site security scanning, cookie banner blocking, and X/Twitter ad hiding. Premium features (included with Stealth Pro subscription) include VPN connection, dark mode injection, fingerprint spoofing, keylogger scrambler, and MAX Stealth mode.

Is Stealth VPN available on Firefox?

Yes. Stealth VPN is available on Firefox Add-ons for Firefox 140+ (Desktop) and Firefox 142+ (Android). It includes VPN proxy tunneling, ad & tracker blocking, malware/phishing protection, cookie banner blocking, WebRTC leak protection, and X/Twitter ad blocking. Premium features are included with a Stealth Pro subscription.

How much does Stealth Sponsor cost?

Stealth Sponsor offers two pricing options: $1.99 one-time purchase (bring your own OpenAI API key) or $3.99/month subscription which includes 1 million AI tokens monthly for transcript analysis with no API key required.

Does Stealth Sponsor work on Amazon Prime Video, Tubi, Peacock and Twitch?

Yes. Stealth Sponsor includes ad skipping for Amazon Prime Video, Tubi, Pluto TV, Peacock and Twitch (mutes ads and overlays a clean screen until content resumes). It also adds a multi-video Picture-in-Picture grid that works on any external video site, and an External Mode that runs AI sponsor detection on non-YouTube videos with available transcripts.

Does Stealth Sponsor block Facebook ads?

Yes. Stealth Sponsor includes a Facebook content blocker that hides sponsored posts, ads, suggested content, and Privacy Sandbox attribution beacons from your Facebook feed.
