About Harpa AI
HARPA AI is a browser extension that pairs several large language models, including ChatGPT, Claude, Gemini, Perplexity, and DeepSeek, with web automation features. Rather than opening a separate chat window, it runs alongside whatever page a user is viewing, letting the AI read, summarize, and act on that content directly. The extension covers a wide range of tasks: summarizing YouTube videos and web pages, drafting and managing Gmail messages, extracting SEO keywords, monitoring web pages for changes, tracking e-commerce prices, scraping structured data, and generating prompts for image tools like Midjourney and DALL-E. It works across Chrome, Brave, Opera, Edge, and Firefox, and integrates with popular sites such as Google Search, LinkedIn, YouTube, Twitter, Amazon, Gmail, and dozens of others where its automation commands can be triggered. HARPA AI is built by HARPA AI Technologies LLC, founded in 2021 in Finland, and reports more than 500,000 users. It offers a free tier alongside paid plans starting around $12 per month for features like cloud command storage and chat history, plus a CloudAI API for developers. Because it depends on injecting AI into third-party websites, its reliability can vary with how those sites change their layouts, and heavier automation features are locked behind paid plans.
