Overview
The web is noisy. You click an article, 4,000 words. YouTubers include sponsor and filler content. Check a Reddit thread, 200+ nested comments. sSummarizer cuts through the noise. One click turns any page into a clean, readable summary.
sSummarizer is a lightweight, browser-native extension that runs entirely on your device. It uses a custom content extractor to identify the main body of text, video transcripts, or nested comment structures, then sends that context directly to your chosen AI provider for an accurate, high-quality summary.
Connect directly to your favorite AI models like OpenAI, Claude, Gemini, OpenRouter, or Perplexity and watch the summary generate in real-time. Keep the conversation going by asking follow-up questions directly in the extension!
