- Navigate to any landing page
- Start hacking! 🚀
Requirements
- Google Chrome (latest version)
- Developer mode for local builds

Core Modes
unFunnelizer offers two powerful modes to reveal hidden content on any page.
Smart Mode
Intelligently identifies and reveals specific hidden "marketing elements" like delayed buy buttons, testimonials, and offers.
.delay, .hidden, .d-none, etc. Best for: Precise revealing without breaking the page layout.
Brute Mode
The "Nuclear Option". Forces display: block !important on every single element that is currently hidden.
Best for: Stubborn pages where Smart Mode misses something.

Video
Show All Qualities
Slower downloadsWhen enabled, the video downloader will show all available quality options (360p, 720p, 1080p, etc.) instead of just the best quality. This may result in slower initial loading as more streams are detected.
Download Speed (Parallel Connections)
Controls how many video segments are downloaded simultaneously. Higher values = faster downloads, but may trigger rate limiting on some servers.
4 (Safe) — Slowest, but safest for sensitive servers
8 (Default) — Good balance of speed and reliability
16-24 (Fast) — Faster downloads, works on most CDNs
32-100 (Very Fast) — Maximum speed, may cause rate limiting
⚠️ Values above 32 may cause rate limiting on some servers. If downloads fail, try lowering this value.
Hard Reset (Clear All Data)
Clears ALL extension data including settings, cached videos, detected pixels, and transcription history. Use this if you're experiencing issues or want to start fresh. This action cannot be undone.
Transcription
Auto-detect Language
ExperimentalWhen enabled, the AI transcription will automatically detect the spoken language instead of asking you to select one. This is experimental and may not always be accurate, especially for mixed-language content.
Keywords (Multi-Language)
Enable additional languages for the Smart Reveal keyword detection. By default, only English keywords are used. Enable these to detect hidden CTAs in other languages.
Portuguese
Brazilian Portuguese keywords
Spanish
Spanish keywords
French
