About
HARPA AI is a browser-based AI assistant and web automation platform distributed as a free Chrome and Edge extension, built to bring AI capabilities directly into everyday browsing without requiring a separate application or subscription. Founded on the principle that AI should work where users already spend their time, HARPA integrates ChatGPT, Claude, and Gemini into a unified interface that operates alongside any webpage — allowing users to summarize articles, draft emails, automate repetitive web tasks, and monitor websites for changes without leaving their browser.\n\nHARPA's feature set spans more than 100 built-in commands covering content summarization, SEO analysis, email drafting, form automation, price monitoring, and web scraping — making it one of the most comprehensive browser AI tools available. The platform's web automation capabilities allow users to record multi-step browser workflows and execute them on demand, positioning HARPA as a bridge between AI writing assistance and lightweight robotic process automation. Target users include marketers, researchers, e-commerce professionals, and knowledge workers who perform repetitive browser-based tasks daily.\n\nHARPA AI has grown to more than 400,000 active users through organic app store and word-of-mouth growth, without major institutional marketing spend. Its free-tier model has driven rapid distribution, while power users upgrade to access higher usage limits and advanced automation features. HARPA competes with browser AI extensions including Merlin and Sider but differentiates through the breadth of its command library, multi-model support, and web automation depth. The combination of AI assistance and browser automation in a zero-install extension fills a gap that neither pure AI tools nor traditional RPA platforms address.
