  HARPA AI

  AI browser agent for Chrome that automates web tasks.

  A browser extension that fuses large language models with on-page web automation, letting an AI agent read, understand, and act on web pages — navigating, extracting data, filling forms, and monitoring sites for changes. It connects to multiple AI providers and ships 100+ preset commands for research, SEO, and writing. Available for Chrome, Edge, Firefox, Brave, and Opera.

  AI insight: Hybrid engine can tap your logged-in ChatGPT, Claude, or Gemini web sessions instead of a paid API key, then automate actions on the page.

  AI insight: One of India's most-installed Chrome AI extensions, 1M+ users; its 'unlimited' Pro plan is really a fair-use query-credit cap.
