HARPA AI

HARPA AI is a browser extension that integrates multiple large language models into a single interface, enabling users to interact with AI directly on any web page. It combines models such as OpenAI GPT-5.4, Anthropic Claude 4.6, Google Gemini 3.1, DeepSeek, Grok, Perplexity, and Meta Llama, allowing users to switch between them or use them in parallel without leaving the browser. The extension activates with a keyboard shortcut (Alt + A), providing contextual AI assistance based on the current page content. One of its primary functions is summarizing web content. Users can quickly generate concise summaries of YouTube videos, blog posts, research articles, and PDF files. The AI extracts key points, highlights data, and condenses long texts into digestible formats, which is particularly useful for researchers, students, and professionals who need to review large amounts of information efficiently. HARPA AI also supports writing and editing tasks. It can draft emails, proofread text, generate articles, and rewrite sentences to adjust tone or clarity. Users can ask the AI to rewrite a paragraph in a more formal style, or to create a draft reply to an email directly from the Gmail interface. The extension works across major web platforms, including Google Docs, Notion, and LinkedIn, enabling seamless integration into daily workflows. Data extraction and automation are additional key features. HARPA AI can extract structured data from web pages, such as product details, contact information, or table entries, and export them to spreadsheets or other formats. It also automates repetitive online tasks, such as filling forms, scraping competitor pricing, or monitoring changes on tracked pages. The hybrid browser automation and AI engine allows users to set up custom workflows,
