A broad omnichannel platform, or focused customer service AI with a fixed price and your data in European hands?

Trengo and Sarrai look the same at first glance. Both let an AI answer your customer questions based on your own knowledge, both are based in the EU, and both charge per conversation. The difference is in the breadth, in what you really see on your invoice, and in where your data ends up. Trengo is a broad platform that brings every channel into one inbox, from WhatsApp to telephony. Sarrai is focused on one thing: taking repeat questions off your plate and keeping your knowledge current, with a predictable price and your data in European hands. Below I compare the two honestly, so you make the right choice.

Pricing model
Fixed packages based on conversations. Boost from €299/month (10 users, 6,000 conversations a year), Pro from €499/month (20 users, 18,000 a year). Each conversation runs for 7 days; if the customer replies later, it counts as a new conversation. AI answers above the included number cost €0.25 to €0.30 each. WhatsApp, voice and AI run through a wallet that tops itself up.
A predictable subscription based on conversations, three clear tiers (€149, €349, €699). No wallet, no top-ups, no separate AI charge. Renaming the assistant and giving it your own avatar are included.
Data & privacy
Dutch company, GDPR compliant. The data sits on Amazon Web Services in a European region. That is still an American cloud provider, so the US CLOUD Act can in theory come into play.

Every answer with a source citation. When unsure, Sarrai says "I don't know" and hands over to a person. On email, Sarrai writes a draft that you review and send.

Where each one excels

Use cases per tool

No platform is best for everyone. These are the situations where each one is genuinely strong.

Trengo is strong for

Deploying broadly across many channels, with high volume.

  • Teams that want to serve WhatsApp, voice, Instagram or telephony from one inbox today.
  • Companies that also work outbound, with WhatsApp campaigns and newsletters to large lists.
  • Organisations with a lot of SaaS tools like Salesforce, Dynamics or Shopify they want to connect directly.
  • Larger support or e-commerce teams, towards 10 to 20 people, that want a broad and proven platform.
Sarrai is strong for

Automating customer service with a fixed price and your data in European hands.

  • SMEs that want to keep their customer data in Europe, hosted in Belgium, with no American cloud.
  • Teams that want a predictable invoice, without a wallet that tops itself up and without conversations that start counting again after 7 days.
  • Smaller teams that don't want to pay for ten fixed users just to get started.
  • Anyone who wants a knowledge base that keeps itself current with updates you approve, plus an expert channel to your own people.
  • Anyone who wants personal guidance and support that stays with you after onboarding too.

Eats its own dog food

Sarrai uses Sarrai for its own support

In your Sarrai backoffice you can talk to Sarrai itself at any moment. A question about a feature, a setting, an invoice: you ask the same AI you give your own customers. If the conversation gets stuck, it escalates automatically to a person, and today that is the Sarrai team directly. So the very flow you offer your customers is the one we use to help you.

That is deliberate. Putting your own customer support on your own product is a strong signal: it works, or we feel it first. And it solves exactly what comes up most in Trengo reviews, namely that the help drops off after onboarding. With Sarrai there is no separate support department you disappear into. The people who build it are also the endpoint when the AI can't work it out.

Want to test it before you choose? Open the demo environment, ask Sarrai a tricky question, and see what happens when it isn't sure of the answer itself.

European and predictable

Looking for a focused, sovereign alternative to Trengo?

Then Sarrai was built for you. Trengo and Sarrai are both European, so the question is not American versus European. It is how far the data stays within Europe, what your invoice does month to month, and who picks up when the AI can't.

Your data on European infrastructure

Your servers and all customer data sit with Combell in Belgium, within the EU. The language model comes from Mistral in France. No American cloud is involved, so the US CLOUD Act does not come into play. Trengo is GDPR compliant too, but hosts on Amazon Web Services, an American provider.

A fixed, predictable price

One predictable subscription based on conversations, with three clear tiers. No wallet that tops itself up, no separate charge per AI answer, and no conversations that start counting again after a 7-day window.

Support that stays with you

Personal guidance to get started, and support that stays with you afterwards. When a conversation gets stuck, it reaches the Sarrai team directly, through the same flow your customers use.

Frequently asked questions

Sarrai vs Trengo: FAQ

What's the difference between Sarrai and Trengo?

Both let an AI answer your customer questions based on your own knowledge. Trengo is a broad omnichannel platform: every channel in one inbox, from WhatsApp and telephony to social, with AI on top, and it targets teams across Europe. Sarrai is focused on automating customer service for SMEs in Belgium and the Netherlands, with a knowledge base that keeps itself current, a fixed price based on conversations and your data in European hands. Trengo goes wide, Sarrai goes deep on one task.

Is Sarrai a good alternative to Trengo?

For an SME that mainly wants to automate repeat customer questions with a predictable price and data in the EU, Sarrai is a strong alternative. If you mainly need many channels such as telephony and social, or you send outbound WhatsApp campaigns, Trengo is a better fit. Many smaller teams choose Sarrai precisely because they value a predictable invoice, a knowledge base that keeps itself current and support that stays with them more than maximum breadth.

Does Sarrai have WhatsApp and telephony like Trengo?

Here Trengo wins today. Trengo serves 10+ channels, including WhatsApp as an official Meta partner, voice and telephony, SMS and the familiar social channels. Sarrai works on website chat and email today, and WhatsApp is on the roadmap. If your customer service runs largely on telephony or social, Trengo is the logical choice on that point. If your questions mostly come in through chat and email, Sarrai covers that fully.

Where is my data stored with Sarrai and with Trengo?

With Sarrai your data stays in European hands. Hosting is in Belgium (Combell) and the language model comes from France (Mistral). No American cloud is involved. Trengo is a Dutch, GDPR-compliant company, but it hosts on Amazon Web Services in a European region. The data sits in Europe, yet the provider is American, so the US CLOUD Act can in theory come into play. For anyone who wants customer conversations to stay fully within European infrastructure, that is a real difference.

Is Sarrai cheaper than Trengo?

It depends on your situation, but the models differ a lot. Trengo works with fixed packages based on conversations, from €299/month for 10 users and 6,000 conversations a year. Three things make the final invoice harder to predict: each conversation only runs for 7 days, so a customer who comes back later counts as a new conversation; AI answers above the included number cost €0.25 to €0.30 each; and WhatsApp, voice and AI run through a wallet that tops itself up automatically. If you're a team of three, you still pay for ten users at Trengo. Sarrai works with a predictable subscription based on conversations, three clear tiers, without a wallet, top-ups or a separate AI charge. Run your own scenario in the price comparison. For current Trengo rates, check trengo.com/prices.

Does Sarrai send answers to customers automatically?

In chat, Sarrai answers questions directly and hands over to a person when it is not sure. On email, Sarrai works with a draft by default. The AI writes the answer, you review it and send it. A wrong answer in an email weighs heavier than in a chat bubble, so there you deliberately keep your hand on the wheel. If you do want email answered automatically for certain question types, that can be switched on case by case.

What guidance and support do I get with Sarrai?

At the start you choose between self-service or personal guidance, so you get results quickly. After that, the support stays with you. If a conversation gets stuck, it reaches the Sarrai team directly, through the same flow your customers use. So we run our own customer service on our own product. In Trengo reviews the opposite is the most common complaint: a strong onboarding, after which the help drops off. That is why you can test Sarrai yourself before you choose, and see how an escalation plays out.
