What is Harpa?
HARPA AI is a Chrome‑based browser agent that combines multiple large language models—such as GPT‑5.4, Claude 4.6, Gemini 3.1, DeepSeek, Perplexity, and Llama 4—into a single extension you can trigger on any web page with the Alt+A shortcut. It acts as an AI copilot that reads, understands, and can act on page content, enabling you to summarize YouTube videos, blogs, and PDFs, answer emails, proofread, generate articles, extract data, and automate routine web tasks without leaving your browser.
Key features include contextual AI responses on top of search engines like Google, Bing, and DuckDuckGo, a built‑in YouTube summarizer with timestamp navigation, a Gmail assistant for categorizing and drafting replies, and a writing assistant that mimics your personal style across emails, social posts, articles, cover letters, and more. HARPA also offers ready‑to‑use AI commands for copywriting, SEO, recruiting, coding help, language learning, and e‑commerce workflows, plus integrations with automation platforms such as Make.com, Zapier, and n8n to turn websites into APIs and trigger IFTTT‑style chains.
HARPA is targeted at knowledge workers, marketers, developers, SEO practitioners, recruiters, content creators, and anyone who repeatedly performs tasks like research, writing, email triage, data extraction, and price or page‑change monitoring. Because it can read and interact with web pages directly, it suits users who want to reduce manual clicking, form filling, and copying‑pasting while maintaining control over their browser and data, especially in environments where privacy and local processing are important.
Harpa pricing
Pricing model: Freemium
HARPA offers a basic free tier and a demo period for premium features, allowing you to try the extension before committing to a paid plan. The basic S plan starts at about 12 USD per month when paid annually, and includes access to the CloudGPT connection, cloud command storage, chat history, reuse of one AI dialogue across multiple browser tabs, and the CloudAI API for reliable access to OpenAI and Claude models. Additional costs may arise if you connect directly to OpenAI API keys or other providers, since usage is then billed per token via those vendors rather than via HARPA’s flat‑rate model.

Frequently asked questions about Harpa
What is HARPA AI?
HARPA AI is a browser extension powered by a hybrid engine that combines large language models like GPT‑5.4, Claude 4.6, Gemini 3.1, DeepSeek, Perplexity, and Llama with web‑automation capabilities. It can read, understand, and act on the content of any web page, supporting tasks such as summarizing articles and videos, drafting and replying to emails, extracting data, and automating form filling and navigation inside your browser.
What is HARPA AI used for?
HARPA AI automates copywriting, email management, web search, online data extraction, and web monitoring. Users deploy it to write and reply to emails, post comments and DMs, summarize or ‘talk to’ web pages, YouTube videos, and PDFs, extract SEO keywords, generate SMM content plans, create Midjourney prompts, fill forms, write blog articles, review CVs and legal documents, plan trips, track competitors and prices, and set up learning plans, among many other workflows.
What makes HARPA AI different from other AI browser tools?
HARPA can both read and act on web‑page content, meaning it can navigate pages, click buttons, extract data, run that data through LLMs, paste results back into web forms, and trigger automation chains on platforms like Zapier and Make.com. It also integrates multiple AI providers into one interface, supports local models, and emphasizes privacy‑by‑design, positioning it as an all‑in‑one AI agent for web browsing rather than a mere chat overlay.
Is HARPA AI free to use?
HARPA has a basic free tier and a demo period for its premium features, allowing you to explore the core functionality before upgrading. The full S plan starts at about 12 USD per month when paid annually and unlocks advanced capabilities such as CloudGPT, cloud command storage, chat history, multi‑tab dialogue reuse, and the CloudAI API while keeping the browser‑resident agent active.
Is HARPA AI CPU‑intensive?
HARPA is optimized so it does not consume CPU when it has no active tasks; it wakes up only when a command is triggered. You can further control resource usage by limiting the number of automations that run simultaneously in the app settings, which is useful on lower‑end machines or when running multiple tabs and extensions.
What does HARPA stand for?
HARPA stands for High Availability Robotic Process Automation. The name reflects its goal of bridging AI and automation by acting as a virtual assistant and digital workforce inside the browser, automating repetitive web tasks while remaining highly available and resilient.
Do I need an OpenAI account to use HARPA?
Generative AI features in HARPA require a connection to an AI provider such as ChatGPT, OpenAI API, ClaudeAI, Gemini, or another supported API endpoint. You can either link a ChatGPT account, an OpenAI API key, or HARPA’s own CloudGPT on the S plan, giving you flexibility in how you route the AI requests.
How does HARPA handle privacy and data security?
HARPA is designed to run on your computer and does not store your website data or actions on remote servers; it only performs the tasks you explicitly instruct. Prompts you send to models are transparently routed to OpenAI, Google, ClaudeAI, or other providers and are not retained on HARPA’s infrastructure, and the extension does not show ads or sell your data.
Which search engines does HARPA support?
HARPA provides AI‑assisted search overlay for multiple engines including Google, Google Scholar, Baidu, Bing, DuckDuckGo, Brave, Yahoo, Naver, Yandex, Kagi, and Searx. On each of these, it can surface AI‑generated answers alongside results, let you ask follow‑up questions, and pull in cited sources from the pages it scans.
Can HARPA generate blog outlines and long articles?
Yes, HARPA includes an extensive library of copywriting prompts that can generate and refine short and long articles, including blog outlines and multi‑thousand‑word pieces, in various writing styles and frameworks. It can also mimic your personal tone of voice and allow step‑by‑step refinement by adding keywords, expanding sections, or re‑writing paragraphs as needed.
