Inside Vex
Everything Vex does, out of the box.
Vex is the AI built into Yaplet — not a bolt-on. It works on every channel your inbox is connected to, answers customers on its own, and only escalates when it really should.
Answers from your content
Vex pulls answers from your knowledge base, FAQs, website pages and uploaded documents — so customers get accurate, on-brand replies.
Cites its sources
Every answer Vex sends links back to the article, FAQ or document it came from — so customers can dig deeper and your team can audit at a glance.
100+ languages
Vex understands and responds in over a hundred languages, automatically matching whatever language your customer wrote in.
Sounds like you
Pick Vex's name, tone of voice and reply style in plain language — friendly, formal, playful, professional. It sounds like your brand, not a generic chatbot.
Hands off to humans
When a question gets complex or sensitive, Vex stops and routes the conversation to your team — with full context, not a fresh start.
Private and EU-hosted
Conversations live in EU data centres, your content isn't used to train public models, and you stay in control of what Vex can see. GDPR-compliant by default.
Works on every channel
Live chat, email, WhatsApp, Instagram, Messenger, Telegram — Vex helps wherever your customers reach you, from one inbox.
Spots knowledge gaps
Vex flags the questions it couldn't answer well, so you know exactly which articles or FAQs to write next.
On 24 hours a day
Vex doesn't sleep. Customers asking at 3am get an answer at 3am, and your team picks up the leftovers in the morning.

Talk to a real person
We use Vex too — try it on us.
Vex reads the conversation, looks at the content you've connected (knowledge base, FAQs, website, uploaded docs) and answers the customer directly — citing the sources it used. When the question is too complex or too sensitive, Vex stops and hands the conversation to your team with full context, not a fresh start.
Only from sources you connect: your Yaplet knowledge base, FAQ entries you write, public website URLs you point it at, and documents or text snippets you upload. Vex doesn't make things up from the open internet — and it tells you which source it used.
Yes. Vex understands and replies in over 100 languages, and it picks the language your customer wrote in automatically. You can also tell it to stick to a specific language if you prefer.
Yes. You stay in control of how aggressive Vex is — set a confidence threshold that decides when Vex should hand off to a human, choose which widgets and channels it answers on, and turn it off anytime. Your agents can also draft replies with AI assistance from inside the inbox while you tune the rollout.
Vex doesn't try to fake it. It either asks a clarifying question, tells the customer it'll connect them to a teammate, or escalates straight to a human. It also flags the question for you so you can add the missing answer to your knowledge base.
No — Vex is part of Yaplet. The free plan includes basic AI features, and paid plans extend AI usage and unlock advanced controls. There's no separate AI tool to buy or wire up.
No. You connect your content and pick Vex's tone in plain language — friendly, formal, playful, professional. There's no prompt template to maintain and no AI engineer required.
