- It can read, click, and extract from web pages, then run the result through an AI model.

HARPA AI is a browser extension that brings AI into every website you visit — but its real hook is automation. Unlike a chatbot you talk to in a separate tab, HARPA can navigate pages, click, and extract data, then process what it finds through an AI model. That combination of web actions plus AI is what sets it apart.
What is HARPA?
HARPA is a browser-based AI agent. It plugs into your browser and gives you access to multiple leading AI models (such as ChatGPT, Claude, and Gemini) directly on the pages you are viewing. Beyond answering questions, it can summarise articles and videos, monitor pages for changes, extract and scrape data, help with writing and email, and run custom automation “agents” you configure for repetitive tasks.
What it does well
- AI plus web actions — it can navigate, click, and extract from pages before applying AI.
- Multiple models — access several leading AI models from one extension.
- Summarising — condense articles and YouTube videos quickly.
- Monitoring and scraping — watch pages for changes and pull structured data.
- Custom agents — automate repetitive web workflows your own way.
Who it is for
HARPA suits marketers, researchers, recruiters, developers, and power users who spend their day in the browser and want AI to actually do things on the web — not just answer questions. If you regularly summarise pages, track competitors, extract data, or repeat the same web tasks, its automation focus is the draw.
Things to keep in mind
A tool that can act on web pages is powerful, so review what any automation does before letting it run, and be mindful of each site terms of service when scraping or automating. As with all AI, verify important extracted data and summaries rather than trusting them blindly.
Our verdict
HARPA is one of the more capable browser AI tools precisely because it pairs multiple AI models with genuine web automation. If your work lives in the browser and you want AI that can navigate and act, not just chat, it is well worth trying. Use its automation thoughtfully and verify anything important it pulls back.
