Usage

Opening HARPA AI

Press Alt+A (Windows/Linux) or Control+A (Mac) on any browser tab, or click the HARPA icon in the toolbar. The sidebar panel opens on the right side of the page.

Minimal Usage Example: Summarize the Current Page

1. Navigate to any article, documentation page, or long-form content URL.
2. Open HARPA with Alt+A.
3. In the AI chat input, type:

/summarize

HARPA reads the current page content automatically (page-aware mode) and returns a structured summary with key points.

Alternatively, type a free-form prompt referencing the page:

Summarize this page in 5 bullet points

Custom Command Template Example

HARPA supports template variables in custom commands. Create a command that always summarizes whatever page you are on:

Please summarize this web page: {{page}}

Save it as a custom command shortcut. When triggered, is replaced with the full text of the current tab.

Other built-in template variables:

Variable	Expands to
	Full text content of the current page
	Text you have highlighted on the page
	URL of the current tab
	Title of the current page

Automation Workflow Example: Price Monitor

1. Open HARPA on a product page (e.g. an Amazon listing).
2. Go to the AUTOMATE tab in the sidebar.
3. Select Price Monitor.
4. Set your target price and notification method (email or webhook).
5. HARPA will check the page on your configured schedule and alert you when the price drops below the threshold.

Vision Mode

Press Alt+V (or Control+V on Mac) on any tab to enter Vision mode. HARPA will analyze images and visual content on the current page. Useful for extracting text from screenshots or asking questions about charts and diagrams.

Accessing the Command Menu

While in the HARPA chat panel, press / to open the built-in command palette. This lists all available built-in commands (summarize, translate, rewrite, extract data, etc.) and any custom commands you have saved.
