3. Usage

3.1. Quick Start

1. Configure a model
2. Open a page, click summary
3. Continue to chat, or try modifying configurations

3.2. Trigger

By default, the summary panel does not open automatically. You can open it in the following four ways:

1. Click the floating ball in the lower right corner of the page (configurable: Yes (default) / No display)
2. Click the action (popup) button, then click the "Summarize" button on the page (configurable: clicking the action (popup) button can Open the panel directly / Open the popup page (default))
3. Click "Summarize This Page" in the page's context menu
4. (Manual configuration required) Configure a keyboard shortcut through the browser extension settings (not the plugin's options page). You can configure a shortcut trigger (recommended Alt+S)

You can also configure Auto open summary panel on new tab

By default, the summary does not start automatically after opening the panel. You need to click the "Sum" button in the panel to start summarizing.

You can configure Auto begin summary to automatically start summarizing when the panel is opened.

By default, the plugin has access to all sites.

You can change the plugin's access permission to On Click in the browser settings:

• Some browsers (such as Edge) can directly run the plugin's functionality on the page with one click of the action icon.
• Other browsers (such as Chrome) acquire page permissions after clicking the action icon, but need to refresh the page to run the plugin's functionality on the page. However, it doesn't matter, you can one step run by the Summarize This Page ⚡ button in the right-click menu (like Immersive Translate extension).

3.3. Error Inspect

Some errors may not be displayed through the UI. You can view the errors of the summary panel through the developer console of the current webpage.

View the logs of the plugin background through the developer console of the background (options) page.

Requests sent to the LLM API can also be viewed in the developer console of the background page.

3.4. Proxy for LLM Requests

This plugin does not provide proxy functionality itself. It can be used with other browser proxy plugins (similar to ProxySwitchOmega) to implement proxying of specified URL traffic.

4. Inspiration

Copying webpage content into a llm website, then entering prompts and viewing the results is a common workflow for many people today. A browser plugin is needed to replace this process.

Currently(*~2025.1), the following provide this functionality:

Type	Product	Cost	Overview	Open Source	User Experience
Small company commercial products	sider.ai, briefy.ai, monica.ai	≈10$/m	Want to create a complex all-in-one system, with endless telemetry	No	Good
Large model vendor plugin ends	Doubao plugin, Kimi plugin	Completely free	Doubao: Wants to create a complex all-in-one system, laggy, endless telemetry, cannot even be put on the extension store	No	Good+
Products listed in the app store by individual developers		Free or ≈4$/m	No maintenance, many are unavailable	No	Poor
Open source	chatGPTBox⚡	Free	Supports multiple model configurations and has made specific website customizations	Yes	Good

chatGPTBox is the only open-source, fully functional webpage summary plugin I found. It is a great project. The interface design of this project is inspired by it, but it lacks prompt customization features. In addition, its technology stack (React) is different from mine, so I decided to develop a new webpage summary browser plugin with my own technology stack (Vue, wxt, vercel-ai-sdk).
