What is Harpa?

Harpa is a ChatGPT overlay tool. Browser extension that runs GPT, Claude, Gemini, DeepSeek, Perplexity and Llama on any web page, with page summarization, Gmail drafting, writing assistance, SEO audits, page monitoring, price alerts and no-code web automation.

Harpa is a Chrome extension that turns the browser into a working surface for AI. Instead of copying text into a separate chat window, you press Alt + A (or the // shortcut) on whatever page you are reading and reach OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek, Perplexity, Grok and Meta Llama from the same panel. The extension reads the page you are on, so prompts arrive with context already attached. Day to day, that context is the point. Harpa summarizes YouTube videos and jumps to the relevant timestamp, condenses long PDFs and blogs, answers Google searches with cited sources, and drafts Gmail replies that match the writer's tone. A Writer feature imitates your own style across emails, tweets, LinkedIn cover letters and long SEO articles, and a library of over 100 ready-made page-aware prompts covers marketing, e-commerce, charting, recruiting and study. Beyond text, the tool automates the browser itself. It can monitor pages for changes, watch product prices on Amazon, AliExpress, Walmart and eBay, scrape listings and prospects from any site, and run automations that click, fill forms and navigate. A hybrid automation and AI engine sits behind this, and custom agents built from your own GPTs can be given access to page content, search and automation functions. Chains can be triggered from Make.com, Zapier, n8n or IFTTT. It suits marketers, SEO specialists, recruiters, copywriters, developers and students who spend the day in a browser and want AI without tab switching. Privacy is handled locally with no logging of conversations, GDPR compliance and support for local models. The pitch is breadth: one extension instead of a stack of single-purpose add-ons. The trade-off is that the feature list is enormous, and the free tier is not the same as the paid one.

How do you use Harpa?

1Install the extension
Add Harpa to Chrome, Brave, Opera, Edge or Firefox from the install page, then pin the icon so the panel is one click away.
2Open the AI panel on a page
Press Alt + A on any website to launch the assistant, or type // inside a text field to trigger quick actions such as grammar check, rephrase or translate.
3Summarize something long
Open a YouTube video, blog post or PDF and ask for a summary. Harpa reads the page content and can jump to the timestamps that matter.
4Pick a ready-made prompt
Browse the prompt library for page-aware automations grouped by marketing, e-commerce, copywriting, recruiting and learning, then adapt one to your task.
5Set up a monitor or automation
Create a page monitor or price alert, or connect Make.com, Zapier or n8n to trigger browser automations that scrape data and fill forms.
6Choose a plan
Compare the free and paid tiers on the pricing page to see which automations and models your workflow actually needs.
