What is HARPA AI
HARPA AI is a comprehensive Chrome extension that integrates several leading AI models — OpenAI GPT-5.4, Anthropic Claude 4.6, Google Gemini 3.1, Grok, Perplexity, and DeepSeek — into one powerful browser agent. It transforms everyday web browsing into an automated, intelligent workflow.
Core Features
One of the standout features is YouTube video summarization. HARPA can extract key takeaways from hour-long videos, enable in-video search, jump to timestamps, and even let you “talk” to videos.
The built-in Answer Engine delivers hallucination-free answers alongside Google Search results with proper source citations. It scans websites and compiles informed, contextual responses.
Gmail Assistant helps clear your inbox by categorizing emails, summarizing long threads, and drafting replies that match your personal writing style. The AI writer can generate tweets, LinkedIn posts, articles, cover letters, CVs, poems, meeting agendas, and more.
HARPA excels at SEO and marketing tasks. It performs AI-driven SEO audits, finds long-tail keywords, creates content calendars, and generates long-form articles (25,000+ words) using 25 different writing frameworks.
Automation and Monitoring
Users can set up page monitors to track changes on any website and receive notifications. Price drop and back-in-stock alerts work on major e-commerce platforms like Amazon, AliExpress, Walmart, and eBay. Over 100 ready-to-use, context-aware prompts cover marketing, learning, recruiting, coding, and productivity.
Privacy and Accessibility
HARPA supports local models such as Meta Llama, does not log conversations, is GDPR compliant, and offers best-in-class privacy. It is accessible via Alt + A or the “//” shortcut and provides quick commands (F — finish draft, G — grammar, P — rephrase, T — translate, etc.).
Pros: Multiple top-tier models in one extension, powerful browser automation, excellent YouTube and Gmail integration, strong privacy focus.
Cons: Some advanced features require a paid plan, learning curve for power users.
HARPA AI stands out as one of the most complete AI browser agents available, ideal for marketers, writers, researchers, and power users who want to supercharge their daily web workflow.
