Trengo is a customer engagement platform that brings email, WhatsApp, social, live chat and voice into one inbox, with the HelpMate AI Agent and AI Journeys. MonoChat focuses on messaging — WhatsApp Business API with coexistence, calls and Flows, plus Instagram, Facebook, TikTok, Telegram, web chat, SMS and voice — and prices by agents, channels and outgoing messages, with AI agents that run on the LLM provider you choose.

Where MonoChat Stands Out

What messaging-first teams usually gain with MonoChat

Your LLM, No Markup

Connect OpenAI, Anthropic, Gemini, OpenRouter, DeepSeek or Ollama with your own key. MonoChat adds no markup to AI usage.

Deep WhatsApp Support

Coexistence with the WhatsApp Business App, WhatsApp calls, Flows, carousel and template messages, and bulk messaging.

Custom Functions and MCP

Let AI agents and flows call your own APIs, connect MCP servers, and embed custom views for your team.

Start Free, Pay for What You Send

The free plan includes 1,000 outgoing messages a month. Incoming messages are never counted.

When Trengo Is the Better Choice

MonoChat is not the right fit for everyone. Trengo may suit you better if:

  • Email is a major support channel for you and you want it in the same inbox as WhatsApp, social and live chat.
  • You want your AI agent trained directly on a help center from the same vendor.
  • You prefer a European-owned vendor with security and GDPR at the core of the platform.
  • You have a larger team and want 10 or 20 users bundled into the plan from the start.

How to Switch from Trengo to MonoChat

A typical migration in four steps

  1. 1

    Move your WhatsApp number

    Your WhatsApp Business API number is registered with Meta, not locked to Trengo. Disconnect it from Trengo and connect it to MonoChat through Meta’s onboarding flow, and plan a short window without campaigns while the switch completes.

  2. 2

    Bring over your message templates

    Export the text of your approved templates. Depending on how the number moves, templates either stay with your WhatsApp Business Account or need to be resubmitted to Meta for approval from MonoChat.

  3. 3

    Import your contacts

    Export your contacts from Trengo as a CSV with labels, custom fields and opt-in status, then import them into MonoChat.

  4. 4

    Rebuild flows and your AI agent

    Recreate your automations in MonoChat’s workflow builder, upload your help center and knowledge documents, connect your AI provider key, and test everything before going live.
