AI Agent Builder for WhatsApp, SMS & RCS
AI Agent Builder

Build an AI Agent That Actually Answers Where Your Customers Message You

Most AI chatbot tools give you a widget for your website and stop there. SMPPCenter's AI Agent Builder gives you one agent - one system prompt, one knowledge base, one set of guardrails - that answers on WhatsApp, RCS, SMS, and Telegram, alongside your website and a REST API, using OpenAI, Anthropic, Azure OpenAI, or Google Gemini. Build it with a guided wizard, ground it in your own content, and deploy it across every channel you already send on.

One Agent, Every Channel

WhatsApp

Answer WhatsApp conversations with the same agent config you use everywhere else.

RCS

Rich, branded RCS conversations handled by the same agent, no separate build.

SMS

Two-way SMS conversations, for customers who never left plain text.

Telegram

The same agent answers Telegram conversations without a separate bot to maintain.

Website Widget

Drop the same agent onto your website with the Website Chat Widget for visitors who never message you directly.

REST API

Call the same agent directly from your own app or system for custom integrations.

Channel access is gated by which of those messaging products are already active on your account - nothing extra to set up if you're already sending on them.

What You Can Actually Build

Guided, No-Code Setup

  • A 7-step wizard: industry template, use case, personality, safety, knowledge, test, go-live.
  • AI-assisted system-prompt drafting to start from, not a blank text box.
  • Draft, staging, and published versions per bot - test before it goes live.

Your Choice of Model

  • Bring your own key for OpenAI, Anthropic, Azure OpenAI, or Google Gemini.
  • Or use platform-hosted models, billed per token with your own markup built in.
  • Set per-bot: provider, model, temperature, and max output tokens.

A Real Knowledge Base

  • Crawl your website, with scheduled recrawls to stay current.
  • Upload PDF, TXT, Markdown, or CSV sources directly.
  • Auto-generated FAQs, glossary, and topics from what you upload.
  • Test search with citations before you trust it in production.

Agents That Take Action

  • Send SMS, WhatsApp, RCS, Telegram, or email as a direct action, not just advice.
  • Call any custom REST API and parse the response back into the conversation.
  • Fire a webhook to notify or trigger your own systems.

Guardrails You Control

  • Topic allow/deny lists and jailbreak-phrase blocking.
  • PII redaction and per-user rate limiting.
  • Custom fallback messages when a question falls outside scope.
  • Escalation to a human on keywords, explicit phrases, sentiment, or repeated failures.

Analytics That Prove It's Working

  • KPI dashboards, trend charts, and channel/CSAT breakdowns.
  • Per-conversation token and cost tracking.
  • Full conversation logs, searchable by bot, channel, and date.

A Profitable Business Layer, Not Just a Feature

Every AI chatbot vendor is selling the same pitch: a widget for your website. What most of them don't have is the messaging infrastructure to go with it. If you're already running SMS, WhatsApp, RCS, or Telegram traffic through SMPPCenter, an AI agent isn't a separate product you have to build a go-to-market for - it's a layer on top of traffic you're already selling.

Bundle It Into What You Already Sell

Reselling WhatsApp or SMS capacity? Offer an AI agent on top as a premium tier, instead of competing purely on message price.

Set Your Own Margin

Platform-billed models are metered per token with markup built in - you control what you charge clients, whether that's per bot, per conversation, or bundled into a plan.

One Build, Every Channel You Sell

Configure a client's agent once and it answers on whichever channel - WhatsApp, RCS, SMS, Telegram - they've bought from you, instead of rebuilding per channel.

FAQ

Frequently Asked Questions

Bring your own API key for OpenAI, Anthropic, Azure OpenAI, or Google Gemini, or use platform-hosted models billed per token with your own markup built in - your choice, per bot.

WhatsApp, RCS, SMS, Telegram, a website chat widget, and a raw REST API - all from a single bot configuration, gated only by which of those messaging products are already active on your account.

Yes. A bot can be given tools to send SMS, WhatsApp, RCS, Telegram, or email, call any custom REST API with the response parsed back into the conversation, or fire a webhook - all configured per bot.

Not automatically - there is no built-in CRM connector. Human handoff flags the conversation in the dashboard; if you want a lead pushed into your CRM, wire that up as a custom API or webhook tool on the bot.

Yes - point it at your website (with scheduled recrawls), or upload PDF, TXT, Markdown, or CSV files. The knowledge base auto-generates FAQs, glossary terms, and topics from your sources, with hybrid search and citations you can test before going live.

Guardrails per bot: topic allow/deny lists, jailbreak-phrase blocking, PII redaction, per-user rate limiting, and custom fallback messages - plus configurable escalation to a human on keywords, explicit phrases, sentiment, or repeated failures.

Yes - manage multiple independently configured, independently versioned bots (draft, staging, published) from one account, and call any of them as a step inside the platform's Journey/Workflow Builder.
