Inside Vex
Everything Vex does, from day one.
Vex is built into Yaplet, not a separate tool you wire up. It works on every channel in your inbox, answers on its own, and only escalates when it 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 reply links back to the article, FAQ or document it came from. Customers trust the answer, and you can check Vex's work in one glance.
100+ languages
Vex understands and responds in over a hundred languages, 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 blank chat.
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 any question it couldn't answer well, so your next help article writes itself instead of being a guess.
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, 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.
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 picks the language your customer wrote in. 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.
No. Vex only answers from the content you've connected, and when it isn't confident, it doesn't guess. It asks a clarifying question, tells the customer a teammate is coming, or hands the chat straight to a human. The question also gets flagged for you, so the gap gets fixed for next time.
No. Vex is part of Yaplet. The free plan includes basic AI; paid plans extend usage and unlock advanced controls. There's no separate AI tool to buy, no per-resolution fee, no usage surprises at the end of the month.
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.
