Key Takeaways

Let Me Know When is an AI tool that monitors other websites for changes and informs you.
It’s ideal for keeping track of competitors and their activity online.
The tool doesn’t have as many features or number of pings as competitors, but is significantly cheaper.

Keeping an eye on the competition isn’t easy, but keeping dozens of tabs open to do so isn’t light on your browser either. If only there were an AI that could do the monitoring for you. But as you probably suspect, we wouldn’t be discussing it if we didn’t also have possible solutions, so here they are.

In this article, we’ll be taking a look at the Let Me Know When AI tool and how it can monitor sites and let you know when anything changes.

Keeping an Eye on Things

AI for business monitoring is not a new invention in the machine learning space. Automating tasks is something AI was made to do, and the busywork of constantly checking for site changes is prime real estate for tools that are designed to take over. Let Me Know When is an AI tool that joins other tools like Visual Ping, Distill.io, and Wachete to regularly pings sites for changes and alerts users.

A Closer Look at the Let Me Know When AI Tool

Let’s see what this tool has to offer users:

Features

Let Me Know When provides users with real-time, automated monitoring of sites for stock changes, specials, news stories, job postings, etc., and reports them to the user. It works very effectively as a competitor monitoring AI, keeping tabs on certain websites, and alerting you to any developments that may occur.

Let Me Know When also offers users a strong stable of templates to get started on a monitoring workflow that works best for keeping up with the competition, including:

Customer review monitoring across competitor socials
Pricing alerts to check for sales and deals offered
Google Trends analysis to see where the market is heading
Product display monitoring to see what’s on offer

The focus is clearly on simplicity and user-friendly design. In addition to the templates, the tool sends alerts to users either by means of Slack or email. There’s no app support, but these two channels aren’t necessarily tied to a device.

One thing missing from this tool is API integrations, which can be found in other competitors. There’s no cloud monitoring either. The range and frequency of the checks that Let Me Know When conducts are also far less. For example, VisualPing offers up to 50,000 checks across 500 pages per month, while Let Me Know When offers, at mos,t 5,400 checks across 30 websites. It’s not necessarily a deal breaker, considering the price.

What It Costs

Not every business can afford to keep an eye on the competition, quite literally. Many monitoring tools offer great (and frequent) coverage at accordingly high prices. Let Me Know When doesn’t offer the range, but has much lower prices. It works on a tiered payment system, billed monthly or yearly, with a free trial period.

The tiers ($3.99 at the lowest and $19.99 at the Advanced Tier) differ in their features, but primarily in the number of checks, workflows, websites, and communication channels. It’s ideal for personal use or for smaller businesses.
