About the product
No. You connect your WhatsApp or Telegram, upload your documents, and the agent is ready. We guide you through setup — and you get 15 days of full-access trial.
From your own data: your catalog, your calendar, and the documents you upload. It doesn't improvise — it answers with real information about your business.
No. It frees them up. The AI handles the repetitive stuff and anything outside business hours; your team sees every conversation, steps in whenever it wants, and focuses on what really matters: closing.
Yes, via MCP: the open standard that connects AI to your systems. Your CRM or catalog connects as tools the agent can use in conversation. Ready-made connectors for CRMs by sector are on the roadmap.
Each business operates in an isolated, verified space: only your agent sees your data. Encrypted credentials and an audit log of every action. Built to operate under GDPR.
Yes: the agent answers phone calls with the same brain as WhatsApp, Telegram and web chat — same data, same history — and the conversation is transcribed into the same customer record. It is enabled like any other channel; reach out if you want to see it in a demo.
Yes: a public API with keys and permissions for your developers, and our own MCP server to connect Nuntius to your own AI agents or code editors. No closed catalog of endpoints yet — reach out if you want to be among the first to try it.
Yes. Every user, every access key and every integration has its own permissions: what it can see and what it can do. By default, nobody sees or does anything until you explicitly grant it — so you avoid accidental access. Actions the agent can run are also marked one by one as internal (your team only) or also visible to the customer.
Nuntius doesn't depend on a single provider: we work with several top-tier AI models and activate whichever performs best for your case, with an automatic backup model if the main one fails. You don't have to choose or configure anything technical.
Your contract is set in euros or US dollars depending on your location, and the whole process — price, charge and invoice — happens in that same currency, with no surprise conversions.
Inside your own dashboard you have an AI support assistant, trained on our manuals, that answers instantly. If you need more, human support is available too.
Yes: when the agent detects it needs human intervention, it alerts the assigned owners with an in-app bell and by email, in real time. You can install the dashboard as an app on your phone so you never miss an alert.
Yes, as an advanced option: you can connect your own MCP server under your own responsibility — you decide what it exposes. For most businesses we recommend our curated integrations instead, closed by default and enabled action by action.

About the WhatsApp Business API
It's the messaging channel Meta offers businesses to automate conversations at scale — different from the regular WhatsApp Business app. We use it because it's the only option compatible with an AI agent that answers 24/7 without anyone keeping a phone open, with template sending, attachments, and full traceability.
Meta requires your business to be formally registered (with a verifiable tax ID), a Meta Business Manager account, and a website confirming the business is real. We guide you through the official signup process (Embedded Signup) from within the platform, with no technical configuration to touch.
When a customer messages you, you have 24 hours to reply with free text; after that, you can only reopen the conversation with a template Meta has pre-approved. The agent handles this automatically — free text inside the window, a template when it's needed — so you don't have to think about it.
Yes, both Meta and GDPR require it: you can only send marketing templates to people who've given consent. Any contact can opt out at any time by writing STOP or BAJA, and the system honors it automatically, excluding them from future sends.
Meta measures your number's quality by how your customers respond — blocks, complaints, ratings — and that score determines how many messages you can send per day. Replying fast, not overwhelming people with unsolicited messages, and keeping templates relevant raise it; blocks and spam lower it.
The number you connect to the agent moves onto the official API and can no longer be used at the same time from the WhatsApp Business mobile app — they're two incompatible systems on the same number. Many businesses choose to set up a new number for the AI and keep the one they already use in the app for what they handle by hand.
No. The agent qualifies the customer, answers the repetitive stuff, and books what it can resolve on its own; when a person is needed, it hands off the conversation. Your team sees the whole thread in the inbox and can take over (human intervention) at any time.
From the knowledge base you give it: the documents you upload — catalog, terms, hours, FAQs — get indexed, and the agent answers by citing that real information. It doesn't invent facts about your business that you haven't given it.
It says so — it doesn't improvise an answer when it doesn't have the information, and it escalates the conversation to someone on your team. You see the alert in the inbox and can step in without the customer noticing any change of channel.
Yes, if attachments are enabled on that channel: voice notes are transcribed automatically and images are described so the agent understands what's sent, and documents are read. Videos, for now, are only received and shown to your team — the agent doesn't analyze them.
