Two tools, one goal
You have two ways to let Yaplet answer for you: Vex AI and chatbot workflows. From the outside they look the same — something replies to your visitor without you having to. Inside they work completely differently, and picking the wrong one is the most common reason a first setup disappoints. Both belong to a brand, and you find each of them in the Brand section of the menu.
Vex AI — the AI agent
Each brand has exactly one Vex, at Brand → Vex. There is no list of AI chatbots to pick from any more. Vex answers from everything the brand knows — its knowledge bases, documentation sets, uploaded files, website pages we read for you, question-and-answer entries and the product catalogue — all managed on one screen, Brand → Knowledge. When a visitor writes, Vex searches that material and answers in its own words.
The same material also answers phone calls, writes the suggested replies your team sees in the inbox, and feeds AI social posting. It is one search over one pool, with nothing to connect up.
- Powered by a large language model (LLM)
- Answers open questions it has never seen before
- Replies in the visitor's language automatically — 100+ of them
- Searches content written in up to three different languages at once, each source in its own language
- Links to the knowledge base article or documentation page it used
- Hands the conversation to a person when you have told it to
One naming note, because you will see it all over the dashboard: Vex is called an AI agent, and the word chatbot is now kept for the scripted workflows below.
Chatbot workflows — the scripted builder
A workflow is a script you draw in a drag-and-drop builder. It belongs to one brand and lives at Brand → Workflows. The bot follows exactly the path you designed: show a message, offer buttons, ask a question, branch on the answer, collect data, hand over to a person. Every step is deterministic — the same input always produces the same result.
The list has a Channels column showing where each script can actually run. A workflow can run in the chat widget, in Facebook and Instagram messages and on phone calls — but some steps rule some channels out. A Form step means it cannot run on Facebook or Instagram. A Form, Link, Buttons, Reply-time, Request-agent, Collect-data or Ask-question step means it cannot run on a phone call. Hover the column and it tells you which.
- No AI involved — fully predictable and auditable
- Best for structured processes: lead capture, triage, onboarding
- Supports branching logic and data collection
- Can hand over to Vex mid-script with the AI Bot step
If you run more than one brand, you reuse a script with Copy to another brand… on that same list — there is no attaching one workflow to a second widget.
At a glance
| Vex AI | Chatbot workflows | |
|---|---|---|
| Where it lives | Brand → Vex | Brand → Workflows |
| Handles open questions | Yes — it searches what the brand knows | Only the paths you scripted |
| Requires a script | No | Yes — you build every step |
| Predictable output | No — the AI writes each reply | Yes — deterministic |
| Collects structured data | Through API tools on Brand → Knowledge | Built in — the collect-data step |
| Languages | Replies in 100+, searches up to three at once | Only the language you wrote it in |
| Where it can run | Chat. The same brand knowledge also answers phone calls and writes inbox suggestions | Chat, Facebook, Instagram and phone calls — where its steps allow |
| Best for | General support questions | Triage, lead capture, onboarding |
When to pick Vex AI
Choose Vex when:
- Your visitors ask open-ended, unpredictable questions
- You already have help articles, documentation or files worth answering from
- You want the AI to handle most chats without scripting every answer
- Visitors write in different languages
- You want a link back to the source article in the reply
When to pick chatbot workflows
Choose workflows when:
- You need a fixed path — collect an email, show pricing, route to the right team
- Outcomes must be predictable and auditable
- You are building an onboarding flow or a qualification sequence
- You want a different script running on different pages of your site
Using both at the same time
You do not have to choose one or the other. A common setup: a workflow fires when the widget opens, collects the visitor's name and topic, then hands over to Vex for the open questions — or to a person if the case is complex. The AI Bot step inside any workflow hands over to that brand's Vex, so the brand needs a Vex agent for that step to do anything at all.
