About 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.

Key Features

AI-powered summaries: extracts page content and produces concise, structured summaries with key points, notable facts, and main takeaways
Two modes: TL;DR (bullet-point takeaways under 200 words) and Reformat (full-page Markdown with images, links, tables preserved)
Bilingual output: toggle between English and Chinese with a single click; each language gets its own cache
Smart caching: revisiting a page shows cached summary instantly with relative timestamp; refresh button forces a fresh fetch
Markdown + highlighting: full GitHub-flavored Markdown rendering with syntax highlighting via highlight.js
Keyboard shortcut: Cmd+Shift+S (Mac) or Ctrl+Shift+S (Windows/Linux) to open side panel without mouse
Configurable model: set any OpenAI-compatible model in Options; defaults to deepseek-v4-flash ($0.14/M input tokens)
Privacy-focused: API key stored in chrome.storage.sync, never leaves your machine; no analytics, no tracking, no intermediate server
