HARPA AI Review — Web Automation With AI — Monitor, Extract, and Automate

HARPA AI is a browser automation extension that connects to ChatGPT, Claude, Gemini, and other AI models to automate repetitive browser tasks. It can monitor webpages for changes, extract structured data, run multi-step automation sequences, and execute custom AI commands on any page — all from a sidebar without writing code. It is significantly more powerful than basic AI chat sidebars.

Key Features

HARPA can monitor specific webpages for changes and notify you when something updates — a competitor's pricing page, a product availability notice, a job listing, or a social media profile. The monitoring runs without you keeping the tab open.

Web data extraction lets you pull structured information from pages — product prices, article lists, search results, social media metrics — into a format you can use without manual copying. Creators monitoring competitor analytics or tracking content trends use this regularly.

HARPA's AI commands work on any page content — you can ask it to summarise what's on the page, extract key facts, generate a response to page content, or perform custom multi-step workflows using the text visible in the browser.

The prompt library contains community-created templates for specific tasks — competitor analysis, SEO review, email drafting, content summarisation. These work as starting points that can be customised for your specific workflow.

HARPA supports switching between AI models mid-session, so you can use Claude for summarisation and GPT-4 for generation in the same workflow without leaving the sidebar.

Who Is It For

Creators who do repetitive browser-based research — monitoring competitor pages, extracting data from multiple sources, tracking pricing or content updates — and want those tasks automated rather than done manually each time. HARPA is for users comfortable investing time in setting up automation that pays back repeatedly.

If you need simple AI chat assistance for occasional tasks, simpler extensions like Monica or Sider provide the same chat access with less complexity. HARPA's value is in its automation and monitoring capabilities — if you're not using those features, the added complexity is unnecessary.

Pros and Cons

• ✅ Page monitoring is a genuinely unique capability not available in simpler AI sidebars
• ✅ Multi-model support with switching between AI providers
• ✅ Community prompt library provides useful starting point templates
• ❌ Free tier limits automation runs and monitoring instances
• ❌ Requires more setup time than simpler AI sidebars to get full value from automation features

Pricing

The free plan includes limited monthly automation runs and page monitoring instances. Paid plans start at around $15/month for increased limits. The features are most valuable with a paid plan if you run monitoring or data extraction regularly.
