About
HARPA AI is a feature-rich Chrome extension that brings together the world's leading AI models—OpenAI GPT-4o, Anthropic Claude 3.7, Google Gemini 2.0, DeepSeek, Meta Llama, and Perplexity—into a unified browser copilot accessible on any web page with a single shortcut (Alt+A). Designed for professionals, marketers, developers, and content creators, HARPA dramatically reduces time spent on repetitive online tasks. Key capabilities include a YouTube and web page summarizer that extracts key insights in seconds, a Gmail assistant for categorizing, summarizing, and drafting context-aware replies, and an AI writer that learns and mimics your personal style for emails, LinkedIn posts, tweets, cover letters, and long-form SEO articles. HARPA also doubles as a powerful web automation platform. Users can build no-code browser automations to scrape data, fill forms, click buttons, and trigger workflows via Zapier, Make.com, and n8n. Its price-drop tracker monitors virtually any e-commerce site including Amazon, eBay, and Walmart. For SEO professionals, HARPA conducts AI-driven audits, extracts long-tail keywords, segments audiences, and generates full content calendars. Over 100 ready-to-use prompt templates span marketing, recruiting, coding, e-commerce, and language learning. Privacy is a core priority—HARPA does not log conversations, is GDPR compliant, and supports local models like Llama for fully on-device inference.
