Set up chatbots that answer common questions, collect details, and hand off to a person when needed.
Chatbot products cover several different jobs: scripted question flows, lead qualification, support triage, knowledge-based answers, and increasingly AI agents that can hold longer conversations. Buyers should separate visual flow builders from generative AI, then check what customer data a bot can access and exactly how it transfers a conversation to a person. These five options fit different chatbot workflows, so the list is organized around use case, with no overall ranking.

For CRM-based chat flows
#1 of 5 in Chatbots
HubSpot's chatbot builder is closely tied to its CRM. Teams can create visual sequences for qualifying leads, booking meetings, answering common support questions, opening tickets, or moving contacts into other workflows; because information collected by the chatbot is written back to the CRM, the conversation can use existing contact details and contribute additional data for later sales or service activity.
Service-centered automation
#2 of 5 in Chatbots
Zendesk AI agents can answer from approved knowledge and progress into more structured automated conversations. Teams can define customer use cases, connect each one to flexible generative procedures or branching dialogues, and authorize actions or API integrations where needed. When a conversation needs a person, it can pass into Zendesk's broader ticketing and routing environment instead of ending at the bot.
AI plus inbox routing
#3 of 5 in Chatbots
Crisp combines its support inbox with Hugo, an AI agent trained from website content, knowledge-base articles, files, and Q&A snippets. Hugo can answer questions, detect conversation intent, route customers to selected inboxes or workflows, and escalate when its configured answer-confidence threshold is not met; that makes the chatbot useful for both self-service responses and first-line triage.
For knowledge-based AI chat
#4 of 5 in Chatbots
Tidio's Lyro serves conversational customer support using information supplied through configured data sources. It can ask follow-up questions, use recent conversation context, interpret images, and transfer a request to a human agent when the available knowledge does not cover the answer. Guidance, audiences, multilingual support, and handoff configuration let teams shape how the AI behaves.
Advanced conversation routing
#5 of 5 in Chatbots
Intercom uses Workflows to build bot-led conversation paths in its Messenger and supported channels. A workflow can start when somebody opens a new conversation, visits a particular page, or sends a message, then collect information, branch on conditions, apply tags, or route the request. Fin AI Agent can also be inserted when the flow needs generative answers instead of fixed bot steps.

A traditional chatbot builder usually follows rules, buttons, conditions, and predefined branches designed by the team. An AI support agent can generate responses from approved knowledge and may interpret a wider range of natural-language requests. Some products now combine both approaches, using structured flows for predictable processes and AI when the conversation cannot be mapped neatly in advance.
A handoff is useful when the bot lacks reliable information, the request falls outside its authorized scope, the customer explicitly asks for a person, or a workflow requires specialist judgment. Better implementations pass the existing conversation and collected details to the agent. Teams should configure these cases before launch instead of treating escalation as an exception discovered after deployment.
Some can use CRM attributes, conversation history, order data, account details, or other connected information, but access varies by product and integration. This can make answers or routing more relevant, yet it also increases the need for permissions and careful data handling. Buyers should check exactly which fields the chatbot can read, modify, and pass to downstream workflows.
