# Automation features overview

Our goal at HARPA AI is to bring the future of AI-assisted personal web automation.

HARPA automation capabilities can be divided into two segments: AI Automations & Monitoring Features.

# AI Automations

# Monitoring Features

The most basic feature of HARPA AI web automation is its ability to monitor data on web pages. To access the web monitoring, switch to AUTOMATE tab in HARPA AI interface.

Then pick what you would like to monitor, e.g. a price, page content, line of text, a data element or simply ask it to refresh the page periodically e.g. if you are monitoring a KPI dashboard.

HARPA AI will refresh the web page periodically in the background and will notify you whenever the page, price or the data you monitor changes. The monitoring feature is used in a wide range of applications, including:

  • Buying when price drops. Create web monitors that periodically extract prices from any e-commerce platform, such as Walmart, Amazon and H&M, and notify you when prices drop, saving you money on online purchases.
  • Snatching the best deals. Monitor web pages for specific text to appear (e.g. Discount) or disappear (e.g. Out of Stock) to be the first snatching the best offers, buying products or claiming appointments.
  • Report Website Downtime. Set up a HARPA monitor to check if a website or blog is down or has been defaced.
  • Auto-refresh Pages. Periodically auto-refresh web pages, track appointment slots availability, jobs and vacancies, articles and legislations, changes in competitors’ pricing pages, competitor product rollouts, hotels, and airline tickets.
  • Turns Websites into APIs. API-fy any website for which no official API is available. Build data dashboards and IFTTT chains for your business and customers. Connect HARPA to 3rd party applications via webhooks and / Integromat
  • Track competitors. Use HARPA AI to keep an eye on your competitor websites and receive notifications whenever they update.
