Two tools, one goal
Yaplet gives you two ways to automate conversations in your widget: Vex AI and chatbot workflows. From the outside they look similar — a bot replies to your visitor. Inside, they work completely differently.
Vex AI — the AI agent
Vex reads your knowledge base, uploaded documents, public URLs, and product feeds. When a visitor sends a message, Vex finds the best answer from your content and replies in natural language — no scripts, no fixed paths, no buttons you had to design in advance.
- Powered by a large language model (LLM)
- Answers open-ended questions it has never seen before
- Detects the visitor's language automatically — 100+ languages
- Can cite the source article inline in its reply
- Hands off to a human agent when it isn't confident
Chatbot workflows — the rule-based builder
Workflows are visual node graphs you build in a drag-and-drop editor. The bot follows the path you design: show a message, offer buttons, ask a question, branch on the answer, collect data, or hand off to a human. Every step is deterministic — the same input always produces the same output.
- No AI or LLM — fully predictable and auditable
- Best for structured processes: lead capture, triage, onboarding
- Supports complex branching logic and data collection
- Can call Vex AI as a node mid-flow
At a glance
| Vex AI | Chatbot workflows | |
|---|---|---|
| Handles open questions | Yes — reads your sources | Only paths you scripted |
| Requires a script | No | Yes — you build every node |
| Predictable output | No (LLM-generated) | Yes (deterministic) |
| Collects structured data | Via context tools | Natively (collect data node) |
| Multi-language | 100+ languages, auto-detected | Your content's language only |
| Best for | General support Q&A | Triage, lead capture, onboarding |
When to pick Vex AI
Choose Vex when:
- Your visitors ask open-ended, unpredictable questions
- You already have a knowledge base or documentation site
- You want AI to handle the majority of chats without scripting every answer
- Visitors write in different languages
- You want citations back to source articles in every reply
When to pick chatbot workflows
Choose workflows when:
- You need a structured path — collect email, show pricing, route to the right team
- Outcomes must be predictable and auditable
- You're building an onboarding flow or a qualification sequence
- You want different bots on different pages of your site
Using both at the same time
You don't 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 routes to Vex AI for open Q&A — or to a human agent if the issue is complex. The AI Bot node inside any workflow lets you hand off to Vex mid-flow.
