Artificial intelligence (AI) has a long and complex history, but it’s undeniable that it has become ever-present across industries and uses in the last few years. From the dawn of ChatGPT to the dozens of AI tools used in marketing, security, data analysis, and more, AI now pervades daily life and transforms business functions. 

The best AI tools on the market can make processes smarter, teams more efficient, and people more productive. The first step in using AI tools effectively is gaining a thorough understanding of what AI tools are and which ones will best serve your needs. 

What is AI?

AI, or artificial intelligence, refers to a computer system that can perform a task that would otherwise require a human to complete. Recognizing speech, generating written text that follows language structures and responds to tone specifications, making decisions, and solving problems are all examples of AI capabilities. 

The purpose of AI is to mimic human cognitive functions through computer systems. 

How Does AI Work?

AI uses algorithms and computer models that continuously learn from human inputs and data. These models allow machines to learn and adapt as more data is added. To initiate this process, an AI model must be given a large amount of data so that it can identify trends and pinpoint correlations. 

The more data an AI model can work with, the more effectively it can perform. 

What is an AI Tool?

An AI tool is an application or software program that leverages AI models and algorithms to perform a specified task. Using machine learning techniques and a specialized algorithm developed with a certain goal output in mind, AI tools can help with a wide variety of business needs from customer journey personalization to data analysis and content creation.

How AI Tools Work

AI describes any algorithm or model that adapts and improves with every iteration of its use and every input of data. An AI tool uses that same concept, using machine learning, natural language processing, and computer vision to deliver solutions for a predefined problem. 

Humans create AI tools by defining models and entering large amounts of data so that the algorithm can identify patterns and generate its own data that follows those same parameters. 

Of course, every AI tool works differently based on its purpose. 

Benefits of AI Tools

There are plenty of reasons why AI tools continue to gain popularity across organizations. The following are some of the most impactful benefits of using AI tools. 

Time & Resource Saving

AI helps humans to automate processes that are tedious, repetitive, and time consuming. Implementing AI productivity software tools frees up time for individuals and organizations alike, which in turn frees up resources. 

No more paying skilled workers to waste their time sorting data or running analytics. Instead, companies can leverage these workers for more high-priority tasks while AI tools complete repetitive tasks.

AI greeting

One AI tool that can save sales and marketing teams countless hours while improving results is Tavus. Tavus can turn a single recorded video template into thousands of personalized video messages. 

This AI sales tool allows teams to follow up with customers on what feels like an individual basis, without every team member taking hours out of every week to record the same video over and over again. 

In marketing efforts, create email marketing campaigns that include Tavus videos that speak directly to prospects by name, mention their organization or recommended products, and spark a feeling of connection early on in your communications. Without AI tools like Tavus, this degree of personalization at scale would be impossible.

Increased Productivity  

By automating tasks that are repetitive and tedious, AI tools allow for increased productivity among employees. This allows organizations to be more strategic in their hiring and task allocation efforts, leaving space for activities that truly move the needle instead of using company resources on administrative tasks that no one enjoys doing.


Because AI tools are always learning from new data and patterns, they are highly adaptable and flexible. This allows them to better complement human skills by inspiring creativity and pinpointing trends before humans may otherwise be able to. 

Using machine learning, AI tools can recommend updated models based on shifts in customer behavior and response patterns. 

AI Tool Examples: What AI Tools Are Used For

Most people think of ChatGPT or in-depth data analysis functions when discussing AI tool examples. In reality, there are AI tools to assist with almost every business function and decision.

This method allows for authentic human voice and expression, without requiring countless hours of recording. 

When to use AI video generation: 

  • Customer welcome emails

With Tavus, you can use AI generation for all of the cases above, and better yet, you can automate the process of sending them. By creating a video template and setting up a programmatic video trigger that integrates with the rest of your processes, you can send prospects and customers personalized videos based on their actions without lifting a finger. 

Through integrations with Salesforce, Mailchimp, and more, Tavus enables users to set up event-based triggers that automate the creation and sending process once set up.
