HARPA AI

What is HARPA AI?

HARPA AI is a browser agent that sits on top of any web page and lets you call models from OpenAI, Anthropic, Google, DeepSeek, Perplexity and Meta from a single shortcut. It reads the page you are on, so you can summarize articles, PDFs and YouTube videos, draft email replies, proofread, or have it write long articles from an outline. Page monitors watch a site for changes and alert you to price drops or items back in stock, and a scraping feature pulls data from sites and hands it to Make.com, Zapier or n8n. Over 100 ready-made commands cover SEO, copywriting, recruiting and learning, and you can build and schedule your own. A free Demo plan has daily message limits; paid plans run from €14.3 per month billed annually, with a one-time lifetime option at €238. You can connect your own API keys or use web sessions from ChatGPT, Claude and Gemini instead of spending tokens.

Use cases

Why use HARPA AI

• One extension replaces separate chat tabs for several AI models, so you can switch models without leaving the page you are reading.
• Responses are page-aware, which saves copying and pasting text into a chat window.
• Monitors for price drops and page changes run in the background and notify you, so you do not need to keep checking sites.
• You can pay per month, per year or once for life, and bring your own API keys to control spend.
• The vendor says it does not log conversations and supports local models, which suits privacy-minded users.
