Asyntai pricing 2026: what each AI reply costs and which plan fits

TL;DR

Asyntai pricing runs from $0 to $449 a month, billed per AI reply: Free gives you 50 replies, Starter $39 gives you 800, Standard $139 gives you 15,000 and Pro $449 gives you 50,000. Annual billing knocks about 10% off.

The number that matters is cost per reply. Starter works out at 4.9 cents a reply and Standard at 0.93 cents, so Starter costs about 5x more per reply and caps out at roughly 200 chats a month. Standard is also the first plan with human takeover, escalation and tickets. For most live sites, Standard is the real entry price.

There's no overage. When the monthly allowance runs out, the bot stops replying until the next cycle. If your chats end up as tickets in Zendesk, Freshdesk or Gorgias, eesel's AI helpdesk teammate counts a whole chat as one credit and keeps working the ticket after the chat ends. That's how Beautek turned 20 website chats in a month into Zendesk tickets for its sales team.

How much does Asyntai cost?

Asyntai is an AI chatbot for websites from Advanced AI s.r.o. in Prague. It has four self-serve plans and an Enterprise tier, and every one of them is priced by the number of AI replies the bot can send in a month. I pulled the numbers below from Asyntai's pricing page on October 27, 2026.

Asyntai also shows euro prices: Starter is 35 € (31 € billed yearly), Standard 125 € (112 €) and Pro 399 € (359 €). You can pay by bank transfer if you email the team.

The feature gates are where the plans split. Free only lets you review chat logs. Starter adds 7 features, including chat analytics, Instagram, Messenger, WhatsApp and Discord channels, Zapier, the REST API and lead capture. Standard adds 19 more, including the voice agent, product cards, the real-time data feed, custom tools, human takeover, escalation and support tickets. Pro adds 25 on top, including proactive messages, branding removal, SSO, a reseller dashboard and reply suggestions. If you're weighing the features themselves, my Asyntai review goes through each one.

What counts as an AI reply?

An AI reply is each message the bot sends, not each conversation. A visitor who asks about shipping, then returns, then a discount code, is one chat but three or four AI replies. Asyntai's plan details describe the allowance as the "maximum number of AI replies the bot can send", and in a voice call each spoken answer also counts as one AI reply.

That's the detail that makes the plan names misleading if you skim. Most chatbot pricing I read for this blog counts conversations or resolutions instead, so 800 sounds like 800 customers. It isn't.

At 4 AI replies per chat, which is a fair guess for a support chat with a follow-up question or two, Starter covers about 200 chats a month and Standard about 3,750. If your bot asks clarifying questions or collects an email before answering, the replies per chat go up and the chat count drops. Before you pick a plan, open the chat logs in your current tool and count replies on 20 real conversations. My guide to chatbot analytics shows what else to pull while you're in there.

What does each Asyntai reply actually cost?

Divide the plan price by its reply allowance and Asyntai's ladder looks very different from the sticker prices. Starter is the most expensive plan per reply, by a wide margin.

These numbers assume you use the whole allowance, which is the catch. On Standard, 15,000 replies is a lot of headroom, so a site doing 500 chats a month pays $139 for 2,000 replies and the real cost is about 28 cents a chat. That's still cheap next to most per-conversation bots. My chatbot cost guide puts it next to per-seat and per-resolution models.

The jump from Starter to Standard is the one to plan around. It's +$100 a month for 18.75x the replies, plus handoff and tickets. Pro to Standard is the opposite story: $310 more for 3.3x the replies at almost the same unit price, so you move to Pro for the features (branding removal, more seats, more websites), not for cheaper replies.

Which Asyntai plan fits your volume?

Here's how the plans line up for four buyers, assuming 4 AI replies per chat and monthly billing. The calculator at the top of this post runs the same math on your own numbers.

The second row is the one I'd point most readers to. If a visitor can ever say "can I talk to someone?", you need chatbot escalation, and on Asyntai that starts at Standard. So for a support use case, $139 a month is the real starting price, not $39.

Starter makes sense for one job: an AI that answers product and policy questions on a small site, with the contact form as the fallback. It's the classic AI chatbot vs live chat trade, made on price. If that's you, Asyntai is one of the cheaper ways to do it, alongside the tools in my roundup of Shopify chatbot apps.

What happens when you hit the Asyntai reply cap?

The bot stops replying. There's no pay-per-reply overage and no automatic top-up. Asyntai's Zendesk integration docs say the monthly allowance "applies across all your channels and integrations", and put the limit plainly:

"Once you exceed it, the bot stops replying until the next cycle or you upgrade."

The "across all your channels" part is the bit that bites. Your website widget, WhatsApp, Instagram, Messenger, voice calls, and any helpdesk integration all draw from one pool. Connect the bot to WhatsApp or Instagram during a promotion and those replies come out of the same 800 or 15,000 your website chat depends on.

A hard cap has an upside: your bill never surprises you. The downside is that it fails during your busiest week, which is exactly when visitors need answers. Three things I'd do on Asyntai:

• Size for your peak month, not your average. If Black Friday doubles chat volume, your plan needs to cover that month.
• Keep a human fallback visible. A contact link or email in the widget's custom notice gives visitors somewhere to go if the bot goes quiet.
• Check usage weekly in the first month. Real replies per chat are usually higher than the guess you started with.

What else does Asyntai charge for?

The plan price covers most of what Asyntai does, but five costs sit outside the reply count or show up only when you need them.

Human handoff starts on Standard. Human takeover, escalation, AI notifications and support tickets are all Standard features. Takeover happens in Asyntai's Live Monitoring screen, and tickets land in Asyntai's own Tickets dashboard, not in your helpdesk. Asyntai does connect to Zendesk AI Messaging and Gorgias AI chat, but only as a text-only chat bot.

Phone calls are billed by Twilio. Standard and Pro let the voice agent answer your phone numbers, but you connect your own Twilio account and "Twilio bills the calls on your Twilio account", per the pricing page. Each spoken answer still counts as an AI reply, so voice drains the same pool as chat. My guide to AI voice agents covers what that setup involves.

Seats are fixed per plan. You get 1, 2, 3 or 10 dashboard seats. More than 10 means the Custom Pro add-ons: 15 seats is +$158 a month and 25 is +$316.

Branding removal is Pro only. The "Powered by Asyntai" line stays on every plan below $449 a month. If you run the widget for clients, Pro also adds a white-label reseller dashboard.

Annual plans lock you in. The pricing page notes that "annual plans cannot be downgraded to a lower tier until the billing period ends." Saving 10% is worth it once you know your volume, not before.

Past Pro's limits, Asyntai's Custom Pro page lists monthly add-ons for each limit:

The reply add-ons keep the unit price close to Pro's: 100,000 replies at $898 a month is 0.90 cents each. Voice is the expensive line, since 3,000 minutes adds as much as the whole Pro plan. On Pro and Enterprise, Asyntai also offers free done-for-you setup: it adds your content, writes the AI instructions and styles the widget.

Where do Asyntai's own pages disagree on price?

Two of Asyntai's numbers differ depending on which of its own pages you read. The pricing page is the one I'd trust, since it's the page you pay from, but you should know about the others before you compare plans.

The 800 figure also appears on Asyntai's homepage and its free-vs-starter comparison, so 2,500 looks like an older number that didn't get updated. If you're installing from Shopify and planning around 2,500 replies on Starter, check the dashboard after you upgrade. At 800, a 4-reply chat gives you about 200 chats, not 625.

Is Asyntai worth the price?

For a website that wants an AI answering questions from its own pages, yes. Standard at $139 for 15,000 replies is one of the lowest per-chat prices I've seen for a widget with handoff, voice and product cards. Asyntai is also built in the EU, which matters if GDPR is part of your buying checklist, and its Enterprise page adds zero retention mode and PII redaction. My enterprise chatbot guide lists what else to ask for.

Where I'd hesitate:

• Starter is a trial in disguise. 800 replies and no handoff is fine for testing. For a live store, plan on Standard.
• The hard cap is a real risk. A bot that goes quiet mid-month is worse than no bot, because visitors have already learned to ask it.
• Tickets stay in Asyntai. If your team works in a helpdesk, the AI's tickets live in a second inbox someone has to check. That cost doesn't show on the pricing page, but it shows up in cost per resolution.
• There's no public proof yet. The Shopify listing, the WordPress plugin and the Chrome extension all show zero reviews so far.

How does Asyntai pricing compare with other chatbots?

Every tool in this space bills by a different meter, which is why the sticker prices don't compare. Here's a quick view, using each vendor's own pricing page as of October 27, 2026. My Asyntai alternatives post prices them all for one 2,000-chat site.

On pure price per website chat, Asyntai Standard is hard to beat. The trade-offs are in the last two columns: what happens at the limit, and where a chat goes when the AI can't finish it.

How eesel prices an AI chat differently

I'll be straight about it: if all you need is an AI answering FAQs on a marketing site, Asyntai is cheaper than eesel. eesel's pricing is a fixed monthly credit plan, starting at $299 for 500 credits and $499 for 1,000, with 100 free credits to try it. A chat is 1 credit however many replies it takes, and a ticket is 1 credit however long it runs, so the replies-per-chat guesswork goes away.

What you pay for is the job after the chat. eesel is an AI helpdesk teammate: it answers in a website chat bubble, and when a chat needs a person it opens the ticket in Zendesk, Freshdesk or Gorgias, then keeps drafting and sending replies on that ticket.

Two customers show the shape of it. Beautek, a B2B equipment supplier in Siegen, answered 77 German-language website chats in a month, drafted replies on about 110 Zendesk tickets, and created 20 Zendesk tickets straight from chat, most of them sales leads for the sales team. ClutchLoop, a phone accessory brand on Gorgias, handled about 230 tickets and 27 website chats in a month and sent about 180 replies with no person needed, checking products live in Shopify 76 times.

The cap works differently too. When eesel's credits run out, agents pause and you get an email as you get close, or you turn on overage at $0.80 a credit with a monthly cap you set. Before any of that, you can test it before launch by simulating it on your past conversations.

Try eesel

If your Asyntai chats keep ending with "I'll pass this to the team" and a ticket nobody sees in your helpdesk, eesel is built for that hand-off. It answers on your site from your pages and help center, opens the ticket in Zendesk, Freshdesk or Gorgias, and keeps working it with your team. Start with 100 free credits, no card, and try eesel on your own site.
