Install as an unpacked extension via Chrome developer mode, not available through the Chrome Web Store.

MIT license, use freely for any purpose, including commercial use, as long as you keep the copyright notice.

So what is it?

This is a browser extension for Chrome and Microsoft Edge that reads the text content of whatever web page you currently have open and forwards that text to one of two applications: Whale (an AI chat tool) or SullyOS (another AI platform). The README is written in Chinese. The main appeal is that it can grab text from pages that require you to be logged in, such as Zhihu (a Chinese Q&A site) or Xiaohongshu (a social media platform), where other text-extraction tools sometimes fail. It extracts only the visible text that has already loaded on the page, not images, videos, or canvas content. It does not read cookies, passwords, or account tokens. Once installed, you click the extension icon while viewing any page, confirm the text looks correct in the popup, choose your target application, enter the destination URL, and click Send. When sending to SullyOS, you can also pick which AI character or agent within that platform should receive the content. Installation follows the standard Chrome/Edge developer mode process: you load the project folder as an unpacked extension rather than installing through an official extension store. The project is MIT licensed.

Copy-paste prompts

Prompt 1

Help me modify this Chrome extension to strip HTML tags and clean up extra whitespace from the extracted text before it gets sent to the AI.

Prompt 2

I want to add a keyboard shortcut to this extension so I can send page text without opening the popup. Show me how to add a command in the manifest.json file.

Prompt 3

This extension sends text to Whale and SullyOS. Help me add a third destination option that posts the extracted text to a local Ollama API endpoint instead.

Prompt 4

The extension only captures visible text. Help me also extract text inside hidden accordion sections that are already in the DOM but collapsed and not visible.
