HARPA AI

Overview

HARPA AI is a next-generation AI browser agent designed to unify the power of multiple large language models within your everyday browsing experience. Positioned as the #1 AI agent for web browsing, it delivers contextual, practical AI assistance on any web page. With a simple keystroke (Alt + A), users gain instant access to leading models such as GPT-5.4, Claude 4.6, DeepSeek, Gemini 3.1, Llama 4, and Perplexity without leaving the page. HARPA combines a hybrid Browser Automation/AI engine, allowing it to understand page content and execute actions such as summarizing, extracting data, clicking buttons, and filling forms. Its best-in-class privacy design supports local models like Meta Llama, does not log conversations or actions, is GDPR compliant, and can be paired with any LLM the user prefers.

At its core, HARPA functions as a multi-purpose productivity assistant. It can summarize YouTube videos, blogs, and PDFs in seconds, pulling key takeaways and enabling timestamp jumps and interactive dialogue with video content. Its Answer Engine provides hallucination-free responses directly alongside Google Search, complete with source citations, by scanning websites and compiling informed answers. The Gmail Assistant helps categorize incoming emails, summarize long threads, and draft contextual replies that match the user's tone of voice. As a writer, HARPA mimics the user's writing style for emails, tweets, LinkedIn cover letters, and SEO-optimized articles of unlimited length, supported by over 100 ready-to-use prompts for resume refinement, language practice, SMM content, code fixes, and more.

Beyond content generation, HARPA excels at automation and data extraction. It can monitor web pages for updates, track price drops and back-in-stock alerts across e-commerce platforms such as Amazon, AliExpress, Walmart, and eBay. Users can scrape data, automate web searches, and trigger workflows with Make.com, Zapier, or n8n, or bring custom GPT agents into the browser. For marketers and SEO professionals, HARPA performs AI-driven SEO audits, extracts long-tail keywords, segments audiences, creates content calendars, and compiles keyword reports. The integrated Midjourney Wizard generates highly detailed image prompts, while the Language Wizard provides grammar correction, explanations, study plans, and learning resources for any language and proficiency level.

HARPA also offers quick shortcuts and template-driven article writing: pressing F finishes a draft, G checks grammar, P rephrases, T translates, S searches, and E explains. It can generate 25,000+ word articles in 25 writing frameworks, refining and adding keywords at each step. With its privacy-by-design approach, HARPA runs locally, does not store user data, and is trusted by over 500,000 professionals and teams, with an average review score of 4.7. It is suitable for a wide range of use cases, from instant research and copywriting to HR tasks, product development, and e-commerce operations, making it an indispensable AI companion for anyone looking to work smarter, not harder.
