Flow chatbot
- Understands only buttons, menus and keywords
- Off-script questions fall into the fallback
- Every change means a new flow
Chatbots follow a script.
AI agents follow the goal.
Flow chatbots get stuck when the customer leaves the menu.
Nuvia's AI agent answers, qualifies and moves the conversation forward on WhatsApp.
Why chatbots get stuck
What's the difference between a chatbot and an AI agent?
A flow chatbot follows a fixed script of menus and buttons, drawn path by path. An AI agent understands the conversation in plain language, answers from the company's knowledge base and guides the customer to a goal, like qualifying or booking a meeting.

Side by side
Chatbot vs AI agent on WhatsApp, point by point
The same conversations, two ways to handle them. The difference shows when the customer leaves the menu.
| What to compare | Flow chatbot | Nuvia AI agent |
|---|---|---|
| How it understands the customer | Through buttons, menus and keywords | Through the conversation, in plain language |
| When the customer goes off script | Falls into “I didn't get that” | Answers and returns to the stage goal |
| Where answers come from | The fixed text in each block | The Knowledge Center, with your documents, URLs and texts |
| When audio, a photo or a PDF arrives | Doesn't understand what arrived | Transcribes the audio and reads photos, PDFs, stickers and links |
| How it's built | Boxes, arrows and exceptions drawn by hand | Stages with instructions and criteria, built by Agent Builder in minutes |
| To change something | Redraw the flow and test path by path | Ask in one sentence and approve the change |
| When a person is needed | Sends it to the queue | Calls your team with the summary and stage |
| When the customer goes quiet | The conversation stops until someone remembers | Follow-up on the cadence you set |
| After the conversation | A message history | Summary, Lead Score and an updated CRM |
Audio, photos, PDFs, stickers and links
Customers send whatever they want. The agent understands
A flow chatbot waits for a number or a button. Nuvia's AI agent transcribes audio, reads photos and PDFs, understands stickers and links, and uses all of it to answer with the right context.
- Audio transcribed and used in the answer
- Photos and PDFs read: receipts, invoices, screenshots
- Stickers and links understood in the context of the conversation
- What the agent understood goes into the summary and the next step
Beyond answering
The agent works the conversation through to the next step
In the same conversation, it calls your team, qualifies, follows up, books the meeting and updates the CRM.
AI and team in the same conversation
Turn the AI on by stage or by funnel. With a person in the conversation, the stage, summary and analysis stay up to date.
Summary, sentiment and Lead Score
Every conversation ends with a summary, sentiment and temperature. For sales, BANT, GPCT or MEDDIC and a 0 to 100 score based on your ICP.
No replyFollow-up at the right time
When a customer goes quiet, the agent reaches out again at the cadence you set, with a message tied to the context. During business hours or at any time.

How the agent works
Stages with a goal instead of boxes and arrows
Each Smart Funnel stage has a plain-language instruction and a criterion to move forward. The agent picks the next question from the conversation, without relying on a menu.
- Instructions written the way you'd explain them to a teammate
- The agent moves the stage when the criterion is met

FAQ
Questions about chatbots and AI agents
What's the difference between a chatbot and an AI agent?
A flow chatbot follows a fixed script of menus and buttons, drawn path by path. Nuvia's AI agent understands the conversation in plain language, answers from your knowledge base and guides the customer to the goal of each stage.
Is an AI chatbot the same as an AI agent?
Not always. Many chatbots use AI only to detect intent and stay locked into the drawn flow. Nuvia's AI agent picks the next question from the conversation, answers from your knowledge base and moves the stage when the criterion is met.
When does a flow chatbot still make sense?
For short, fixed menus where the customer only picks between a few options. When customers write in their own words, send audio or need to be qualified, the AI agent does a better job.
What is an AI agent for WhatsApp?
It's an agent that talks to customers on WhatsApp in plain language: it answers from the company's knowledge base, qualifies, books meetings and hands off to the team when needed. At Nuvia, it works inside the Smart Funnel, with stages, criteria and follow-ups.
How do I build an AI agent for WhatsApp?
With Agent Builder, you explain your process in Claude, ChatGPT, Gemini or Cursor, or send your manuals and playbooks. It sets up funnels, stages, knowledge and follow-ups as a draft for you to review, simulate and activate.
Does the Smart Funnel have stages too?
Yes. You define stages, criteria to move forward, follow-ups and actions. The difference is that you don't draw every possible path in advance: the agent picks the next question based on the conversation.
Can I control what the agent says?
Yes. You write the instructions for each stage, connect documents from the Knowledge Center and simulate before going live. Changes to a live agent ask for your confirmation.
Does the agent understand audio, photos and documents?
Yes. It transcribes audio, reads photos and PDFs, understands stickers and links, and uses all of it in the answer and in the conversation summary.
Does the agent replace my team?
No. It handles the conversations it can resolve and calls a person when needed, with the conversation summary. You can also turn the AI off per stage or for the whole funnel.
How long does it take to replace my chatbot?
With Agent Builder, the first draft of the agent is ready in minutes from your own documents. Then you review, simulate and go live when you're confident.
Which channels does the agent work on?
WhatsApp, with booking straight into your team's Google Calendar.
Does it work with my CRM?
Yes. There are integrations with HubSpot, RD Station and Salesforce, plus API, webhooks and MCP for any other system. With your CRM, sync works both ways.
