What is a conversational AI chatbot?
A conversational AI chatbot is software that understands a question written in plain language and answers in full sentences. It keeps the context of the conversation across several turns. A rule-based chatbot follows a fixed script of buttons and keywords. The difference is explained in chatbot vs conversational AI.
The term covers two kinds of product.
- Business platforms. A company trains the chatbot on its own content and puts it on a website, in a helpdesk or on a messaging channel. The seven tools in this list are business platforms.
- General assistants. ChatGPT, Claude and Gemini answer anyone's questions from general knowledge. A short section near the end covers them.
Real deployments at banks, airlines and retailers are collected in conversational AI examples.
How these conversational AI chatbots were ranked
These conversational AI chatbots were ranked on five criteria, in this order.
- Resolution and handoff. Can the chatbot close a customer service conversation, and does a person take over in the same tool when it cannot?
- Knowledge sources. What content can the chatbot learn from, and how does that content stay current?
- Pricing unit. Does the vendor charge per plan, per message, per conversation or per resolved outcome?
- Entry cost. What does the lowest paid plan cost, and is there a free plan or a free trial?
- Third-party reviews. What is the G2 rating, and how many reviews sit behind it?
No tool is best overall. Each one has a "best for" label. Fin and Tidio rank first and second because each one includes the agent inbox that takes the handoff. SiteGPT is this site's own product. It ranks third because it does one job in this category, answers from your own content, and it does not include a full helpdesk.

What a conversational AI chatbot costs
A conversational AI chatbot costs from $0 to $750 a month on published self-serve plans, plus usage on the tools that meter it. The vendors do not share a unit, so the two tables below keep each vendor's own unit.
Cost of 1,000 AI-handled conversations a month
Two tools in this list publish a price per conversation or per outcome that scales to 1,000 a month. Both totals use annual billing.
Tool | Plan cost | Usage cost | Monthly total | 12-month total |
Fin with one Essential seat | $29 | 1,000 outcomes at $0.99: $990 | $1,019 | $12,228 |
Botpress Plus | $150, with 250 conversations | 8 packs of 100 at $65: $520 | $670 | $8,040 |
Botpress Plus is $349 a month cheaper than Fin with one seat, a saving of 34% and $4,188 over 12 months. The two units differ. Fin bills only the conversations it resolves, and Botpress bills every conversation with at least two messages from the user. Botpress Plus also includes $25 of AI usage a month.
Price per 1,000 units on the entry plan
This table divides each entry plan by its included usage. The units are not the same thing, so read each row on its own.
Tool and plan | Plan price | Included usage | Price per 1,000 units |
SiteGPT Starter | $59 a month, billed monthly | 4k GPT-4.1-mini messages | $14.75 per 1,000 messages |
Botsonic Starter | $19 a month, billed monthly | 1,000 messages | $19 per 1,000 messages |
Chatbase Hobby | $40 a month, billed monthly | 700 message credits | $57.14 per 1,000 credits |
CustomGPT Standard | $99 a month, billed monthly | 1,000 queries | $99 per 1,000 queries |
Botpress Plus | $150 a month, billed annually | 250 conversations | $600 per 1,000 conversations |
Tidio Lyro add-on | $32.50 a month, billed annually | 50 Lyro conversations | $650 per 1,000 Lyro conversations |
Fin | No plan fee for the AI agent | Pay per outcome | $990 per 1,000 outcomes |
One conversation usually holds several messages, so a per-message price and a per-conversation price cannot be compared directly. More vendors are priced in the AI chatbot pricing comparison.

ChatGPT, Claude and Gemini: general assistants are a different category
ChatGPT, Claude and Gemini are general conversational AI assistants. A person opens the app and asks about any topic. The assistant answers from its general training and from what the person pastes or uploads.
A business platform does a different job. It answers a company's customers from that company's content, on that company's website, with a handoff to that company's team.
Question | General assistant | Business platform |
Who asks the questions? | The person who holds the account | A company's customers and visitors |
Where do the answers come from? | General training, plus files the person adds | The company's website, documents and help center |
Who takes over? | No handoff to a company's team | The company's own team |
If you want the ChatGPT experience on your own content, the steps are in how to train ChatGPT on your own data.
