Trengo and SimplyBoost both started in Utrecht, but they solve different problems. Trengo is an omnichannel inbox where a team of people answers email, WhatsApp, Instagram, live chat and phone calls together, with an AI agent called HelpMate on top. SimplyBoost starts with the AI agent: it answers customers from your own content, collects leads and brings your team in when a person is needed. If most of your messages are questions the AI could answer, you pay far less for that with SimplyBoost, and the price doesn't move with every AI conversation.
For most businesses that want AI to answer customers, SimplyBoost is the better Trengo alternative: AI replies are included in a flat €39, €89 or €169 a month, on your website, WhatsApp and Instagram. Trengo is a shared inbox for larger teams, from €299 a month on yearly billing for 10 users, and adds €0.25 to €0.30 for every conversation its AI agent handles.
Our verdict
Choose SimplyBoost if you want AI to take the first reply on your website, WhatsApp and Instagram at a fixed monthly price. AI replies, lead ratings, calendar booking and handover to Slack, Zendesk, Freshdesk or Gorgias are in every plan, and you can compare the plans in a minute.
To be fair
Trengo still suits teams of ten or more people who answer most conversations themselves and want email, phone and messaging in one shared inbox.

Trengo lists integrations with Shopify, WooCommerce, Magento and Lightspeed, and has introduced Dessa, an AI agent for ecommerce brands. SimplyBoost's Shopify store assistant, included from Growth at €89 a month, recommends products from your synced catalogue, builds a cart with a checkout link and answers "where is my order?" on your website, WhatsApp and Instagram.

Most teams do this in an afternoon and keep Trengo running until the answers look right.
Step 1
Add your website, FAQ pages and documents such as your returns policy. The knowledge base guide shows every source type.
Step 2
Install the widget with one snippet, the WordPress plugin, the Shopify app embed or Google Tag Manager. Trengo can keep running next to it while you test.
Step 3
Pick email, the dashboard, Slack or your helpdesk, and decide which topics always go to a person. See the handover guide.
Step 4
Take twenty real questions from your Trengo inbox, ask them in the chat, and add an answer wherever the agent comes up short.
Step 5
Connect your WhatsApp Business number through Meta's embedded signup and link Instagram. A WhatsApp number works with one platform at a time, so pick a quiet moment for that step. The WhatsApp guide has the details.
Plans, limits and yearly prices are on the pricing page. When you're ready, start a 7-day free trial with 100 AI replies, no credit card needed.
For businesses that mainly want AI to answer customers, SimplyBoost is the best fit: AI replies are included in a flat €39, €89 or €169 a month on your website, WhatsApp and Instagram. If you need a shared inbox for email and phone calls with a large team, another inbox tool is closer to what Trengo does.
Trengo Boost costs €349 a month, or €299 a month billed yearly, for 10 users and 500 conversations a month. Pro costs €599, or €499 billed yearly, for 20 users and 1,500 conversations. Extra conversations cost €15 to €18 per 100, and every AI conversation adds €0.25 to €0.30 (trengo.com/pricing, checked 7 October 2026).
Yes. HelpMate, Trengo's AI agent, is part of its plans, but every conversation it handles carries an AI surcharge of €0.25 on yearly billing or €0.30 on monthly billing. SimplyBoost includes 500, 2,000 or 6,000 AI replies a month in the plan price.
For AI answers, almost always. SimplyBoost starts at €39 a month with 500 AI replies, and Trengo starts at €299 a month on yearly billing before any AI surcharge. One conversation can hold several AI replies, so compare against your own volume.
Yes, the number belongs to your business. You connect it to SimplyBoost through Meta's embedded signup. A WhatsApp Business number is connected to one platform at a time, so plan the moment you move it with both providers.
