Casey Rowland
TL;DR
AI chat software is software that uses AI to hold real conversations with people, on your website or support channels, and answer their questions in natural language.
The term covers a few different things: consumer AI assistants, live chat with an AI layer, and AI support agents that resolve customer questions end to end.
For a business, the one that matters is an AI support agent trained on your own content, measured by resolution rather than deflection.
What to look for: trains on your data, resolves and escalates cleanly, works across channels, and prices in a way you can predict.
When you type in "AI chat software" into a search engine, or LLM search, what is it that you're looking for? This is one of those things that could mean slightly different things to everyone, and everyone has a slightly different intent when they are search that term.
Some people are looking for a ChatGPT-style assistant to chat with. Some people are looking for just a traditional chatbot.
But, savvy business owners typically are looking for something beyond just a chatbot. They're looking for a suite of AI agents that help them with their business. They're looking for a software that helps talk with to their customers, answer questions accurately, and take work off of them, or their team.
In this post, we'll cover what "AI chat software" actually means, the different types that are out there, and how to choose the right one.
What is AI chat software?
AI chat software is software that uses artificial intelligence, usually large language models (LLMs), to hold natural conversations with people and answer their questions in real time. Over the past three years, the market has moved to an LLM model vs. a scripted chatbot that matches keywords with canned replies. AI chat sofware understands the context of the question that a person asks, draws on a body of knowledge to answer, and can carry a conversation across follow-up questions.
This is a game changer for businesses. No more guessing what people are going to ask. Or diving through mounds of data to find the most common questions or phrases. LLM's can do all of that heavy lifting for you.
What's even better, AI chat software can be trained specifically for your business. You can train it on your own product, website, documentation, help articles and policies so it answers with information specific to your business; not just some generic information that may or may not be accurate.
The main types of AI chat software
There are four different categories that an AI chat software can fall into. Before you start going and trying a bunch of different platforms, having a general idea of which type you're looking for will save you a bunch of time.
Category | What it does | Best for |
|---|---|---|
Consumer AI chat | General assistants like ChatGPT that you chat with directly | Personal writing and research |
AI live chat | Live chat tools with an AI layer bolted on top | Teams that want humans first, with AI assisting |
AI support agents | AI trained on your business that resolves customer questions end to end; uses multiple channels to interface with customers | Automating customer support and sales |
Rule-based chatbots | Scripted decision trees that match keywords to answers | Simple, static FAQ deflection |
Most people who are searching for AI chat software, are actually are looking for an AI support agent(s). They're looking for a product that will help them reduce their support volume, and help customers in real-time without adding additional headcount. We break down the differences in more detail in our other post: AI support agent vs. AI chatbot.
What to look for in AI chat software
There are some quick things to look for with any type of AI chat software. We do a deep dive in our buyer's guide to evaluating AI chatbot platforms, but some of the quick hits are:
It trains on your data. The software should learn from your help docs, product, and past conversations. If it cannot ingest your knowledge, it will give generic answers that frustrate customers.
It escalates cleanly. When AI cannot help, the handoff to a human should carry the full conversation and context, no cold transfers, no repeating the question.
It works across channels. One agent across your website, email, and messaging apps, with shared memory, beats a separate tool for each.
It is priced predictably. Understand the plan before you buy. Watch for metered models where cost spikes with volume, and for add-ons that stack up.
It resolves, not just deflects. Ask how the vendor defines success. Deflection means the customer gave up; resolution means they got the answer. We make the full case in moving beyond deflection.
How Weav approaches AI chat software
Where does Weav fit in? Weav is an AI support agent that holds real conversations across chat, email, and WhatsApp. The AI agents are trained in just a few minutes on your product, documentation, help articles and historical conversations.
When an AI agent needs to escalate to a human agent, the system cleanly hands off the full context of the conversation to the human agent within a unified help desk. The customer never needs to repeat themselves. The human agent picks up the conversation and helps the customer.
Weav's AI agents are also designed to help your human agents with auto-drafting replies to speed up response times. Human agents have the power to either correct the AI draft, or send off to the customer if they deem it satisfactory. No auto replies are sent without a human agent approving them.

Frequently asked questions
What is AI chat software?
AI chat software is software that uses artificial intelligence, typically large language models, to hold natural conversations with people and answer their questions in real time. In business, it is used to talk to customers on a website or support channels, resolve questions automatically, and hand off to a human when needed.
What is the difference between AI chat software and a chatbot?
A traditional chatbot follows scripted decision trees and breaks when a question is phrased in a new way. AI chat software uses large language models to understand intent and answer from a body of knowledge, so it handles variation, holds a real conversation, and resolves more of what customers ask.
How much does AI chat software cost?
Pricing varies widely. Many tools use tiered plans metered by messages or conversations, often with per-seat and add-on costs, so the total scales with usage. Some offer free starter plans. Weav, for example, has a free plan and paid plans starting at $29 per month. Always confirm how a vendor meters usage before you commit.
What should I look for in AI chat software?
Prioritize software that trains on your own content, measures resolution rather than deflection, escalates to humans with full context, works across your channels with shared memory, and prices predictably. Be wary of tools that only match keywords or that only handle one channel.
Can AI chat software handle customer support?
Yes. A business-grade AI support agent trained on your documentation can resolve common support questions such as order status, returns, billing, and account issues around the clock, then escalate the harder cases to your team. This is the primary use case for most companies evaluating AI chat software.
