Choose **TL;DR** for bullet-point takeaways or\n**Reformat** for a clean, readable Markdown version of the\nfull page with images, links, and tables preserved. Both modes support\nEnglish and Chinese output, streaming results word-by-word as the AI\ngenerates them. Your API key stays on your machine — no analytics,\nno intermediary servers.\n\nfrom the toolbar or\n\nCmd+Shift+S\n\nKey stored in Chrome,\n\nnever leaves your box\n\nNo build step, vanilla JS,\n\n~15 source files\n\n## What it is\n\ncwsum is a Chrome extension that puts AI summarization one click away on any webpage. Click the toolbar icon (or press Cmd+Shift+S) and the side panel opens with a structured summary of whatever you’re reading. The extension extracts the page’s visible text — stripping out navigation, sidebars, ads, and scripts — and sends it to the AI endpoint you configure.\n\nYour API key lives in `chrome.storage.sync`\n\nand is never sent\nanywhere except directly to the API endpoint you specify. The extension\nhas no analytics, no tracking, and no intermediate server. It is a thin\nclient between your browser and your AI provider. Page content goes from\nyour tab to the model; the summary goes from the model to the side panel.\nNothing else happens.\n\n## Features\n\n**TL;DR** gives you bullet-point takeaways in under 200 words.\n\n**Reformat** restructures the entire page as clean Markdown with images, links, and tables preserved — like a reader-mode that keeps the good parts. Both stream results live as they’re generated.\n\n`Cached`\n\nbadge tells you it came from local storage, with\na relative timestamp (“3m ago”). Click the refresh button\nto force a fresh fetch.\n`⌘`\n\n`Shift`\n\n`S` on Mac,\n\n`Ctrl`\n\n`Shift`\n\n`S` on Windows and Linux.\n\n`deepseek-v4-flash`\n\n, the cheapest DeepSeek model at\n$0.14/M input tokens. Also works with OpenAI, Anthropic endpoints,\nor any compatible API.\n## Keyboard\n\nEverything is reachable from the keyboard or a single click.\n\n`⌘`\n\n`Shift`\n\n`S`/\n\n`Ctrl`\n\n`Shift`\n\n`S` Open the side panel\n\n## FAQ\n\n`deepseek-v4-flash`\n\nas the default — the cheapest\nDeepSeek model at $0.14/M input tokens. You can change the model name\nand API base URL in the extension Options.`gpt-4o-mini`\n\nand\nupdate the API endpoint URL if your OpenAI base URL differs. The extension\nuses the standard chat completions format.## Install & use\n\ncwsum is a Chrome Manifest V3 extension. It runs in any Chromium-based browser (Chrome 116+, Edge, Brave, Arc).
