What is it?
HARPA AI is a hybrid AI browser extension that combines large language models (ChatGPT, Gemini, Claude, Perplexity, DeepSeek) with web automation. It runs locally inside Chrome-family browsers and Firefox, providing AI chat, page-aware commands, web monitoring, data extraction, and no-code automation without sending your browsing data to HARPA servers.
Core capabilities include:
- AI chat on any page with page-aware context (reads the current tab)
- Web automation and monitoring (price tracking, competitor change detection, page auto-refresh)
- Data extraction via webhook integration (Zapier, Make.com)
- Custom commands using template syntax (e.g.
,) - YouTube summarization and email drafting assistance
- Vision mode (Alt+V) to analyze images and visual page content
