Meta Tech ProviderKnowledge Base & RAG
One knowledge base for calls, WhatsApp and website chat
Add your website, documents and FAQs once. Your AI agent answers from them on phone calls, WhatsApp, Telegram and your website — in your customer's language — and shows you what it could not answer.
In short
What is an AI knowledge base?
It is the material your AI agent answers from — your website, documents and FAQs. You add it once, and the same agent uses it on phone calls, WhatsApp, Telegram and website chat.
What can I add to the knowledge base?
A website crawl or sitemap, uploaded files (text, Markdown, CSV and PDF, including scanned PDFs), and pasted text. Customer ticket history from Zendesk, Freshdesk or Salesforce can be added to what the agent knows about each person.
Does one knowledge base work in other languages?
Yes. Write it once, in English for example, and the agent replies to chats in 37 languages and handles voice calls in 50 — English in American, British, Australian, Indian and other accents, Spanish, French, Hindi and more.
Three channels
Tailored for how each channel communicates
A caller needs short spoken sentences; a WhatsApp customer wants tappable choices. The same knowledge, answered the way each channel works.
01 · Voice Calls (Phone)
Spoken Answers on Calls
On a call, the agent answers from the same knowledge base, out loud and in the caller's language. When the answer is not there, it can hand the call to your team instead of guessing.
- Same knowledge base as chat
- Voice agents in 50 languages
- Escalates on "cannot answer" if you choose
- Unanswered questions listed for you
02 · WhatsApp Messages
Answers in the Chat
On WhatsApp, the agent answers from your knowledge base in the customer's language, offers tappable choices when there are options, and can look up products and orders through Shopify once it is connected.
- Replies in 37 languages
- Tappable buttons and lists
- Shopify catalogue and order lookup
- Handover to your team in the inbox
03 · Website Chat Widget
Website Chat from Your Own Pages
Visitors get answers from your help pages and documents in the chat widget, and a returning visitor sees their earlier conversation when they open it again.
- One-line script install
- Earlier thread restored for returning visitors
- Leads captured mid-conversation
- Handover to your team

Crawl your site one to three links deep or import a sitemap, and add a page by URL any time — from the console or the API.
Helpdesk & CRM History
Bring a customer's ticket history from Zendesk, Freshdesk or Salesforce into what the agent knows about that person, and connect Notion as a tool it can look things up in.
Pasted Text & FAQs
Paste policies, opening hours, returns rules and question-and-answer pairs straight into the knowledge base.
FAQ
Knowledge Base & RAG FAQs
How does ThinnestAI reduce wrong answers across voice and WhatsApp?
+
The agent answers from what you give it, and you can have it escalate to a person when a question is not covered rather than guess. No AI system can promise it will never be wrong, so the questions your agent could not answer are listed for you to fill in.
How do we update the knowledge base?
+
Upload a file, re-crawl a page or paste new text in the console, and every agent using that knowledge base answers from it. A URL or text added through the API is indexed before the request returns.
Are our documents kept private?
+
Your documents are isolated from every other workspace, at the database and again in the agent runtime.
