HARPA AI

Press Alt plus A on any page and HARPA reads what's on screen, then answers, summarizes, or rewrites based on that exact content. It works across chat, search results, PDFs, and documents, so you do not have to paste text into a separate tab. This page awareness is what separates it from a plain chatbot window, since the model sees the same page you do.

HARPA connects to OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek, Perplexity, and Meta Llama, and you can switch models mid-task or route different jobs to different engines. You bring your own account or key, or use the vendor's CloudGPT connection for a single reliable link. Local models such as Llama are supported for people who want to keep prompts on their own machine.

Beyond answering questions, HARPA can navigate sites, click buttons, fill forms, and extract data, then push results back to a page or into another app. You build these as AI commands, which are ordered steps that may or may not call a model along the way. It is aimed at tasks on sites with no API, and you can trigger the chains from Zapier, Make, or n8n.

HARPA drafts emails, social posts, cover letters, and articles, and it can generate long-form pieces in multiple writing frameworks, refining or adding keywords as it goes. A style-mimicking mode studies your past writing so the drafts sound like you rather than a generic assistant. The command library ships with over 100 ready-made prompts for marketing, SEO, copywriting, and recruiting.

The Gmail assistant categorizes incoming mail, summarizes long threads, and drafts contextual replies in your tone, which is the fastest win if your inbox is the bottleneck. It works inside the browser where you already read email, so there is no separate app to open. The catch is that heavy inbox use burns messages against your plan's daily and monthly limits.

Set up a monitor and HARPA checks a page on a schedule, then notifies you when it changes, which covers page updates, price drops, and back-in-stock signals. Alerts work on virtually any e-commerce site and many news or listing pages. It replaces the manual habit of refreshing a page, and the free plan includes a limited number of monitors.
