Zenly SlideClean - Premium AI Watermark Remover

Hosted on GitHub Pages License: MIT Privacy First

🧹 Professional, private, and offline watermark remover for NotebookLM slides and images.

Zenly SlideClean is engineered to provide a seamless, high-precision cleaning experience for presentation slides, specifically optimized for Google's NotebookLM exports.


✨ Features

  • 🚀 Instant Cleaning: Zero-latency removal using optimized pixel-cloning.
  • 🔒 Privacy Native: 100% client-side. Your files never leave your browser.
  • 💎 Lossless Quality: Only watermarks are removed; your slide content remains at original resolution.
  • 📱 PWA Ready: Install it as a standalone app on your desktop or mobile device.
  • 🌊 Premium UI: Modern, glassy aesthetics with smooth reveal animations.

🛠️ How It Works

SlideClean uses a sophisticated Local Pixel Interpolation engine. Instead of "blurring" the watermark, our algorithm:

  1. Detects the precise coordinates of the watermark pattern.
  2. Clones surrounding pixels from the slide background.
  3. Patches the area with 100% color matching.
  4. Re-compresses the file locally for a clean download.
