Branch on any answer
Split by keywords, numbers, dates, phone numbers, emails, regular expressions, contact fields, groups or earlier results.
Visual flow builder
Dynamic conversation flows that adapt to every customer
Most chatbots follow a script. Flows in On-chat react: they branch on what people say, look up live data from your systems, remember every answer and change the next message to fit. Build it on a visual canvas, test it in the simulator and run it on every channel.
On-chat is a dynamic visual flow builder for WhatsApp, SMS and voice chatbots, with automated campaigns and live-agent ticketing in one workspace.

Features
Everything that makes a flow dynamic
Flows become dynamic through branching on answers, live data from webhooks, personalised expressions and reusable sub-flows.
Live data from your systems
Call a webhook mid-conversation and use the response straight away, such as an order status, a balance or available time slots.
Personalised with expressions
Insert names, fields and results into any message, and calculate dates, totals and text with built-in functions.
Understands free text
Connect an NLU classifier such as Wit.ai or LUIS and split the flow by the customer's intent.
Reusable building blocks
Send people into another flow and back, so registration or verification is built only once.
Human handoff built in
Open a ticket with a human agent from any step, with the conversation and results attached.
One flow, every channel
The same flow runs on WhatsApp, SMS, Messenger, Telegram and more. Voice flows add IVR menus.
Many languages, one flow
Translate a flow once and every contact automatically gets their own language.
Test safely, track everything
Try every path in the simulator before launch, keep revision history, and see results update live.
How it works
Get started in three steps
You map the conversation on the canvas, add webhooks and expressions to personalise it, then test it in the simulator and launch it from a trigger.

FAQ
Frequently asked questions
These are the questions teams ask most often before building their first dynamic flow.
What makes a flow dynamic?
A dynamic flow changes based on who the contact is and what they say. It branches on answers, pulls live data through webhooks and personalises each message with expressions.
Do I need developers?
No for most flows, which are built entirely on the visual canvas. A developer helps only when you want to connect your own systems through webhooks or the API.
Can a flow use data from my CRM or database?
Yes. A webhook step calls your API, and the response is available to the rest of the flow as @webhook, so you can branch on it or put it in a message.
How do I start a flow?
From a keyword trigger, a schedule, a campaign date, a new conversation, the API, or manually for a group of contacts.
Can I see how people move through a flow?
Yes. The editor shows how many contacts took each path, and every result can be exported.
