What is Voiceflow?
Voiceflow is a chatbot platform that allows you to create AI chatbots for websites and telephony, without writing any code.
You can create an advanced Voiceflow AI chatbot using a drag-and-drop flow builder. Voiceflow features include:
- Flow builder to create chatbot flows
- Collect user information with variables
- Built-in AI: Intents, Entities & Knowledge Base
- Advanced website widget
- Enterprise-ready
Using the Voiceflow Flow Builder
When you get started with creating your assistant, you can manage your chatbot from several tabs in the Voiceflow platform overview:
- Workflows – The place for your chatbot flows
- Knowledge base — Where you train the AI on your data (website & documents)
- Interfaces – Overview of your website and telephony numbers
- Publish – The version history of your chatbot
- Transcripts – An overview of all the conversations people had with your assistant
- Analytics – Analytics dashboard showing stats of your chatbot
- Settings – Here you can control the settings of your chatbot
When you start with your Voiceflow chatbot, you can structure your flows into folders to keep a good overview of your chatbot.
To create your chatbot flows, you can simply drag and drop blocks into the canvas. Each flow in Voiceflow starts with a trigger or an Intent. For example, you have the Start trigger that starts every time someone starts talking with your chatbot:
Creating your first chatbot flow is super easy with Voiceflow’s flow builder. During this Voiceflow review, I’ve noticed certain features that make it even easier.
For example, you can duplicate multiple chatbot elements by simply selecting them and doing Ctrl+C/Ctrl+V:
Or you can use keyboard shortcuts, such as ‘r’ that will bring you directly to testing your chatbot.
You can also test your chatbot directly from the Voiceflow interface. When you are doing this, the blocks in your Voiceflow chatbot flow automatically light up:
This is great, because it makes testing way easier. Now, you can see immediately what decisions your chatbot made and where you are in the chatbot flow.
Voiceflow is definitely among the easiest-to-use chatbot platforms on the market right now. By using the flow builder, you can set up your first chat automations in minutes!

Voiceflow Chatbot elements
Voiceflow offers many chatbot elements that you can add to your chatbot flows.
These chatbot elements are divided into 5 categories:
- Talk – Sending texts, images, videos, and galleries
- Listen – Listening for input from users, such as clicking on buttons, getting email information or listening for intents
- Logic – For adding conditions, setting variables, randomly assign people to paths (for A/B testing)
- Dev – To create API calls, quering your knowledge base or execute code
There enough chatbot elements to create a good chatbot. And there are a few that I would like to point out that are especially useful:
Condition: This lets you use “if-then” statements in your chatbot flows. It creates personalized chatbot experiences for users.
Go to Block: With the Go To Block element, you can reference another block in your Voiceflow chatbot. Because of this, you don’t need to copy-and-paste content, which is great when you want to build a scalable chatbot. Additionally, Voiceflow also has Components, which are reusable chatbot flows that you can use at the end of a conversation. For example, at the end of every conversation you could ask “Is your question answered?”.
Code and Function Blocks: You can run code in your chatbot flows using the Code and Function Blocks. This adds great flexibility. With these blocks, the only limit is your imagination, because you can literally code anything you would like.

Contacts
In Voiceflow, you can’t see an overview of all the contacts that talked with your chatbot. But, you can see all the conversations in the Transcripts section:
For each conversation, you can see all the messages sent between the chatbot and that specific person. Unfortunately, it’s not possible to see the custom fields that are entered during that conversation, which is a bit of a drawback.
On the other hand, you can create unlimited variables in the Contents section in Voiceflow:
And then you can use these variables by collecting user information with the Capture element in Voiceflow.

Voiceflow AI features: Intents, AI Knowledge Base & AI Agents
Voiceflow has advanced AI features. They include Intents, Entities, and training the chatbot on a knowledge base.
Intents & Entities
You can understand the intent of the user by creating an Intent and adding training phrases (called Utterances):
Then, you can use these intents to guide users to specific flows in your chatbot:
Likewise, you can also add entities in Voiceflow:
These entities can be used to automatically grab specific data points from a conversation. And you can also use them to validate data provided by users, such as emails.
AI Knowledge Base
You can also train your chatbot on your own data using the Knowledge Base feature in Voiceflow. Here, you can train your chatbot on 4 types of data:
- Plain text
- Files (PDFs, Word documents or text files)
- Website URLs
- Or Zendesk Helpdesk articles
Once the knowledge base has been trained on the data, you can use it in your chatbot flows by using the KB search block:
You can also set specific settings for your knowledge base. These include the AI Model (GPT-4, Claude, Llama, Gemini or Deepseek), the temperature, the max tokens, and custom instructions.
You can also “bring” your own LLM model, which is great for enterprises. For example, if your company doesn’t want to use ChatGPT for privacy reasons, you can just add your own LLM model to Voiceflow and use that.
Aditionally, Voiceflow offers a LLM model fallback. This lets you automatically switch to a different LLM when there is an outage. This is a truely unique feature, and I haven’t seen this in any other chatbot platform yet:
AI Agents
Voiceflow also offers AI Agents. You can see them as digital workers that can understand instructions and take actions. AI Agents can:
- Auto reply to questions (using knowledge from the knowledge base)
- Execute tasks (like refunding an order)
- And follow specific conversion paths
In Voiceflow, you give the agent instructions by adding a prompt. Then, you can also give it functions (to do tasks), paths (to follow a conversation paths) and access to the knowledge base (to answer questions):
So the Voiceflow AI features are definitely a big plus!

Live Chat
Voiceflow lacks a built-in live chat or a direct livechat integration. This is a drawback, as you can’t transfer the chat from your bot to a human.
They have the code for a live chat integration. However, that’s not a feasible option for most non-technical people.

Channels
With Voiceflow, you can create chatbots for websites and Voice (telephony).
If you want to use Voice, you can register the number via Twilio or Vonage.
Additionally, you can also connect Voiceflow to any channel using their Dialog API. But of course, you need to code to set this up.

Marketing
With Voiceflow, you can add a website widget to your website. You can customize this widget with your Assistant name, description, colours and icon:
The widget has three ways of showing on your website:
- Widget — Traditional chat widget in the bottom-right corner
- Popover — Full screen chat experience that pops-up
- Embed — Integrate the chat interface in your website page
Additionally, the website widget also supports voice. So the users if your website can talk with your chatbot if they want.
Moreover, it’s possible to send proactive message with this widget, but you need to code for this.

For developers or more technical users, Voiceflow supports powerful customization.
You can use the API block to send or receive data from any app with an API:

Great piece! We also just added delays to toggle on your Chatbot experiences and solved all the loading errors you faced, sorry about that 🙂
Templates are absolutely available! You can find them here.
Thank you, Tahsim! I’ve added the templates to my review 🙂
Great article as usual. I created an open source Twilio integration for VoiceFlow a few months ago and I have been working with their API/SDK quite a lot for multiple projects, specially for Tenios IVR.
Their strength is in the API for sure, it is more a dev focused platform as you mentioned.
