HARPA AI is a Chrome browser extension that integrates multiple AI models, including GPT, Claude, Gemini, DeepSeek, and Perplexity, into a single interface accessible on any web page. It automates online tasks such as summarizing YouTube videos and web pages, drafting emails, generating articles, and scraping data from websites. HARPA also supports browser automation workflows that connect with tools like Zapier, Make.com, and n8n. The extension runs locally, does not log conversations, and is GDPR compliant, making it suitable for privacy-conscious users and teams.
