No ads and noise from any page, get a clean AI reformat in one click

cwsum is a free, open-source Chrome extension (Manifest V3) that lets you summarize or reformat any webpage with AI in one click. It opens a right-side panel where you can choose TL;DR for bullet-point takeaways or Reformat for a clean, readable Markdown version of the full page (preserving images, links, and tables). The extension supports bilingual output in English and Chinese, streams results word-by-word, and caches summaries for instant reload. Your API key (for DeepSeek, OpenAI, or any OpenAI-compatible endpoint) is stored locally in Chrome storage and never sent to intermediary servers—no analytics, no tracking. Designed for privacy and speed, cwsum works on articles, documentation, research papers, and any text-heavy page.
