HARPA AI is a browser extension powered by a hybrid AI engine that integrates multiple leading language models including ChatGPT, Gemini, Claude, Perplexity, and DeepSeek with advanced web automation capabilities. The platform serves as an ultimate copilot and AI agent for web browsing, search, and automation tasks, providing access to AI functionality on any website and compatibility with nearly every web service or online application.

The extension automates a wide range of tasks including copywriting, email management, web search, online data extraction, and web monitoring. Users can quickly write and reply to emails, post comments and direct messages, summarize and interact with web pages, YouTube videos, and PDF documents, extract and research SEO keywords, create social media content plans and Midjourney prompts, automate form filling, write blog articles, review CVs and job offers, analyze legal documents, plan trips, track competitors and prices, monitor SERP pages, and create personalized learning plans.

HARPA AI can read, understand, and act upon web page content with the ability to navigate, click, and extract data from websites. The platform runs extracted data through large language models and can paste results back to websites or trigger automation chains through services like Zapier and Integromat. The extension features over 100 preconfigured commands and allows users to create custom automation recipes tailored to their specific workflows.

The platform emphasizes privacy-centric design, running locally on user computers without sending or storing website data on remote servers. It only performs tasks explicitly requested by users and does not display advertisements or sell user data. HARPA AI is optimized for speed and performance, using minimal CPU resources when idle, with options to limit simultaneous automations through app settings.
