The price on a chatbot's pricing page is almost never the price on your invoice. The headline number is the base plan; the AI is usually a separate add-on, metered per conversation or per resolution, and that variable line is the one that quietly grows with your traffic. It is why teams routinely report paying two to four times the advertised price once the AI and the overages are switched on.
This guide breaks down what an AI chatbot really costs in 2026: the five ways these tools charge you, the fees that hide between the lines, and a side-by-side of 7 popular tools at 500, 2,000 and 5,000 conversations per month. Full transparency: Agentorie Chat is our own product, and it is in here, held to the same scrutiny as the rest. If you are still choosing which tool fits your setup, we cover that in our WordPress chatbot comparison and our WooCommerce chatbot comparison.

Why a chatbot's price tag lies
Every vendor optimizes its pricing page for one number: the lowest figure you see before clicking "start trial." The techniques are consistent across the industry, and once you know them, the real cost becomes much easier to estimate.
The base plan rarely includes the AI. Tidio shows a low monthly price, but that is the live chat plan; the Lyro AI is a separate add-on. Intercom shows a per-seat price, but Fin AI is billed on top per resolution. The "from" price you see is the floor, not the result.
The expensive line is variable, not fixed. Per-conversation, per-resolution and credit-based models all share one trait: the better your chatbot works and the more traffic you get, the more you pay. A seasonal spike does not raise your plan price, it raises your usage, and usage is the part no pricing page shows in bold. A store that budgets for the base plan can end a busy month at several times that figure.
Currency and overages add a quiet tax. Several popular tools bill in US dollars only, so a European buyer carries exchange-rate movement plus a card fee. Pass a quota and overage rates kick in. None of these are huge on their own, but they belong in the calculation.
The 5 ways AI chatbots charge you
Almost every chatbot uses one of five pricing models. Each is reasonable in the right situation, and each bites in a specific way. Knowing which model a tool uses tells you more about your future bill than the headline price.
1. Flat or per-seat
You pay a fixed monthly fee, either per plan or per agent seat. This is the most predictable model and the easiest to budget. The catch is that per-seat pricing scales with your team size, and on some tools the AI still sits on top as a separate usage charge, so a "flat" plan is not always a flat total.
2. Per conversation
You pay for each AI conversation, usually as an add-on with a monthly quota and overages beyond it. It feels cheap at low volume because you only pay for what you use. The weakness is peaks: a Black Friday or a viral moment multiplies your conversations, and your bill with them, right when budgeting is hardest.
3. Per resolution or per outcome
You pay each time the AI successfully resolves a query, typically around $0.90 to $1.00 per resolution. The appeal is fairness: you pay only when it works. The downside is that success itself becomes the cost driver, the bill grows linearly with volume, and on some helpdesks an AI-resolved ticket is double-billed as both an AI charge and a ticket. At scale, most of the invoice is resolutions, not seats.
4. Credit-based
You buy a monthly allowance of credits that messages and actions consume at variable rates. It bundles everything into one number, but the consumption rate is often not disclosed clearly, so the same traffic can cost different amounts month to month. This is the model users most often describe as hard to predict.
5. BYOK (bring your own key)
The plugin is cheap or a one-time purchase, but you connect your own OpenAI or Google API key and pay that provider directly for every call. It can be the cheapest route at low volume because there is no SaaS markup, but the API bill is variable, can run from $30 to $200 or more per month on a busy store, and you own the setup and the cost monitoring.
AI chatbot pricing compared in 2026
Here is the overview, then the part that actually predicts your bill: the real cost at three volume levels.
Overview: entry price, billing model and free plan
| Tool | Entry price | AI billing model | Free plan | Data location |
|---|---|---|---|---|
| Tidio | $29/mo | Per conversation (Lyro) | ◐ 50 conv lifetime | Tidio cloud (EU opt.) |
| Intercom | $29/seat/mo | Per resolution ($0.99) | ✗ 14-day trial | ✗ US cloud |
| Crisp | Free | Flat (AI from €95/mo) | ✓ chat only | ✓ EU (Amsterdam) |
| Gorgias | $10/mo | Ticket + per resolution | ✗ 7-day trial | ✗ US cloud |
| Botsonic | $16/mo | Credit-based | ◐ trial | ✗ US cloud |
| WoowBot | Free + Pro one-time | BYOK (your API key) | ✓ Lite | Your WordPress |
| Agentorie Chat | Free | Flat, AI included | ✓ 100 conv/mo | ✓ Your own DB |
Real monthly cost at 500, 2,000 and 5,000 conversations
These are approximate ranges that depend on your automation or resolution rate, your team size and your peaks, so treat them as a starting estimate and verify on each vendor's pricing page before buying. A conversation can also span several messages, which is why message and credit metered tools vary the most.
| Tool | ~500/mo | ~2,000/mo | ~5,000/mo |
|---|---|---|---|
| Tidio | ~$68 | $148 to 348 | $348 to 600+ |
| Intercom | $130 to 250 | $400 to 700 | $1,000 to 3,000+ |
| Crisp | ~€95 | €95 to 150 | €150 to 300 |
| Gorgias | $60 to 150 | $360 to 840 | $900 to 1,200+ |
| Botsonic | $16 to 49 | ~$249 | $249+ overages |
| WoowBot | $35 to 80 | $54 to 134 | $84 to 264 |
| Agentorie Chat | Free (≤100/mo) | Flat plan | Flat plan |
The pattern is the point. Per-resolution and ticket models (Intercom, Gorgias) climb fastest because cost is tied to volume. Per-conversation (Tidio) and credit (Botsonic) climb more gently but still punish peaks. BYOK (WoowBot) and flat models stay the flattest as you scale, which is why high-volume stores tend to drift toward them.
What each tool really costs
The same seven tools, read purely through the lens of money: where each is cheap, and where the cost quietly adds up.
1. Tidio, cheap to start, add-on to scale
Live chat base plan + Lyro AI per-conversation add-onTidio's entry price is friendly: around $29 per month for the Starter live chat plan, with a free tier that includes a lifetime allowance of 50 AI conversations. The trouble starts when you actually use the AI at volume. Lyro is a separate add-on, metered per conversation, so a realistic AI-on setup lands near $68 per month, and a growing store moves into the $148 to $348 range. The model is reasonable while traffic is low, and painful exactly when business is good.
Cost upsides
- Low entry price for live chat
- Free lifetime allowance to trial the AI
- Predictable while AI volume stays small
Where it adds up
- Lyro AI is a separate paid add-on
- Per-conversation metering spikes at peak
- Realistic AI cost climbs to $148 to $348/mo
2. Intercom, premium AI with a per-resolution bill
Seats from $29/mo + Fin AI at $0.99 per resolutionIntercom has excellent AI and a slick product, and a pricing model that surprises people. Seats start around $29 per month on annual billing, but Fin AI adds $0.99 for every resolution on top, with a 50-resolution monthly minimum. On a small store the bill is manageable; at scale the resolution line dominates. A team handling thousands of conversations a month commonly lands between several hundred and several thousand dollars, billed in US dollars only. It is the clearest example of the per-resolution model: you pay precisely because the AI is doing its job.
Cost upsides
- You pay only when Fin actually resolves
- No charge when it escalates to a human
- Strong AI, so a high deflection rate is realistic
Where it adds up
- Resolution cost grows linearly with volume
- No free plan, USD billing only
- Real bills often 2 to 4x the seat price
3. Crisp, flat and European, AI gated higher up
Free chat tier · AI on the ~€95/mo planCrisp is the predictable European option. The free plan covers a basic two-agent live chat, and the paid tiers are flat monthly fees rather than per-conversation meters, which makes budgeting easy. The catch for cost-conscious buyers is that the AI only unlocks on the Essentials plan at around 95 euros per month, so the smallest stores that just wanted a little automation have to jump straight to that tier. Above it, AI credits can add a surcharge, but the core model stays refreshingly flat.
Cost upsides
- Flat monthly pricing, easy to budget
- Useful free plan for basic live chat
- EU billing, no currency surprise
Where it adds up
- AI only on the ~€95/mo plan
- No cheap middle step for small stores
- AI credits can add a surcharge at volume
4. Gorgias, helpdesk pricing that doubles up
Ticket-based plans + AI Agent per resolutionGorgias is a capable e-commerce helpdesk, but its pricing combines two meters. Plans are ticket-based (Starter $10, Basic $60, Pro $360), and the AI Agent is charged on top at $0.90 to $1.00 per resolved conversation, with the catch that an AI resolution counts as both an AI charge and a helpdesk ticket. Add seasonal overages and a Pro store automating part of its volume can climb well past a thousand dollars in a busy month, in US dollars only. Powerful for a real support team, but not the model to pick if predictability is your priority.
Cost upsides
- Low $10 entry to test the helpdesk
- Unlimited agent seats on paid plans
- Annual billing saves around 16%
Where it adds up
- AI resolutions double-billed as tickets too
- Overages spike during peak season
- USD only, AI is always an add-on
5. Botsonic, low entry, opaque credits
No-code AI widget · credit-based meteringBotsonic has one of the lowest entry prices here, from $16 per month for 1,000 messages, which makes it tempting for a small site. The friction is the credit system: usage consumes credits at rates that vary by model and message length, so the same traffic can cost differently month to month, and several users report struggling to predict the bill. The next tiers jump to roughly $40.83 and then $249 per month, and live agent handoff is reserved for the Enterprise plan. Cheap to start, harder to forecast.
Cost upsides
- Very low $16 entry point
- One bundled number, no separate AI fee
- Add-on packs keep small bumps cheap
Where it adds up
- Credit consumption rate is not transparent
- Big jump to the $249 tier
- Handoff and key features behind Enterprise
6. WoowBot, cheap license plus your own API bill
One-time Pro license · bring your own API keyWoowBot flips the model: instead of a monthly SaaS fee, you buy a one-time Pro license (roughly $33 to $49, lifetime) and connect your own OpenAI or Google key. There is no recurring software charge, only the API you consume, which can run $30 to $80 per month on a busy store and more at high volume. At low volume it is often the cheapest real option on this list; at high volume the API bill becomes the variable to watch, and you are the one monitoring it.
Cost upsides
- One-time license, no monthly SaaS fee
- Often cheapest at low volume
- Free Lite version to start
Where it adds up
- You pay the OpenAI or Gemini API directly
- API cost is variable and self-managed
- Can reach $200+/mo at high volume
7. Agentorie Chat, a real free plan and the AI in the price
Official WordPress.org plugin · official PrestaShop Addons moduleFull transparency: Agentorie Chat is our own product. We built its pricing as a direct answer to the patterns above, so here is exactly how it works on cost.
Two choices drive the price. First, the AI is part of the plan, not a separate add-on, so there is no Lyro-style or Fin-style usage meter stacked on top, and no per-resolution line that grows with your best months. Second, there is a genuinely free plan of 100 conversations per month with the AI included and no card, after which you move to simple low monthly plans that stay predictable. Because the indexed data lives in your own WordPress or PrestaShop database, you also skip the data-residency questions that come with US clouds, without paying for separate infrastructure.
Honest limits on cost: the free plan is capped at 100 conversations per month, so a very high-volume store will move to a paid tier, and our paid plans are tiered rather than a single unlimited price. We are also a younger product than Intercom or Crisp, so there is less public price history to compare against. What we will not do is hide the AI behind a usage meter that surprises you in November.
Cost upsides
- AI included in the plan, not a separate add-on
- Genuinely free: 100 conversations/month, no card
- Predictable monthly plans, no per-resolution spikes
- Data in your own database, no separate hosting cost
- Also a one-off custom solution, no subscription
Where it adds up
- Free plan capped at 100 conversations/month
- Paid plans are tiered, not unlimited flat
- Younger product, less public price history
The cheapest right choice for your case
The cheapest tool is not the same for everyone. Here is the lowest-cost sensible pick by situation.
Smallest budget or side project
You want a working AI assistant without a monthly bill while you get started, and you can grow into a paid plan later.
WoowBot or Agentorie ChatGrowing store, predictable bill
Traffic is climbing and you want costs that do not spike with it, so you can forecast next quarter without a spreadsheet.
Agentorie ChatHigh conversation volume
Thousands of chats a month, where per-conversation and per-resolution meters become the most expensive way to pay.
WoowBot or Agentorie ChatFull control over costs
You are comfortable managing your own API key and want to pay the model provider directly with no SaaS markup.
WoowBotSupport team needing a helpdesk
You run real ticket volume across channels and want a flat, all-in-one inbox rather than a per-resolution meter.
CrispPredictable bill plus data control
You want one stable monthly figure and your conversation data kept in your own database rather than a vendor cloud.
Agentorie ChatFrequently asked questions
Yes, but read the fine print, because free often means without AI. Tawk.to and the free tier of Crisp give you live chat for free but no real AI agent. Native plugins like WoowBot have a free Lite version for product search, with the LLM features behind a paid license plus your own API costs. Agentorie Chat offers a genuinely free plan that includes the AI: 100 conversations per month, no credit card. The honest rule: a free live chat is common, a free plan that includes a working AI agent is rare, so check exactly what the free tier covers before you count on it.
Because the AI is metered separately from the base plan, and the meter grows with your volume. Tidio sells live chat at one price and the Lyro AI as a per-conversation add-on on top. Intercom charges seats plus $0.99 per Fin resolution. Both look cheap on the pricing page, but the variable line is the one that bites: when support volume spikes (Black Friday, a product launch), the per-conversation or per-resolution bill spikes with it, while the headline price stays the same. Teams routinely report paying two to four times the advertised seat price once AI and overages are included.
BYOK means bring your own key: the plugin is cheap or a one-time purchase, but you connect your own OpenAI or Google API key and pay that provider directly for every message. WoowBot and AI Engine work this way. It can be the cheapest option at low volume, since you avoid a monthly SaaS markup, but the API bill is variable and can reach $30 to $200 or more per month on a busy store, and you manage the key, the model and the costs yourself. It suits hands-on owners and developers, less so non-technical teams who want one predictable invoice.
It depends on how spiky your volume is. Per-conversation and per-resolution pricing feel cheap when traffic is low, because you only pay for what you use. The problem is peaks: the months when you sell the most are also the months you pay the most, so a seasonal spike can double or triple your chatbot bill exactly when you can least predict it. Flat pricing costs a little more at the bottom but stays predictable through your busiest periods, which is usually what a store owner actually wants for budgeting.
Six things. One, the AI sold as a separate add-on on top of the base chat plan. Two, per-conversation or per-resolution metering that spikes at peak season. Three, overage fees once you pass a quota. Four, double-billing, where an AI-resolved ticket counts as both an AI charge and a helpdesk ticket. Five, credit systems where the consumption rate is not disclosed clearly. Six, currency, since several US tools bill in dollars only, adding exchange-rate risk for European buyers. Always model your realistic monthly volume, not the best case, before committing.
For a small store, start with a real free tier and grow into a flat plan. Agentorie Chat is free up to 100 conversations per month with the AI included and no card, then moves to simple low monthly plans. WoowBot is cheap if you are comfortable managing your own API key. Avoid per-resolution tools like Intercom at small scale unless you have very low volume, and watch Tidio, where the Lyro add-on pushes the realistic cost to around $68 per month and up. The cheapest tool on paper is rarely the cheapest once the AI is switched on, so compare the real, AI-included cost.
In summary
The advertised price of an AI chatbot tells you almost nothing about your invoice. What matters is the model underneath it: a flat fee is predictable, per-conversation and per-resolution meters are cheap at the bottom and steep at the top, credits are hard to forecast, and BYOK trades a SaaS fee for an API bill you manage. Match the model to how spiky your traffic is, and you avoid the classic surprise of budgeting for the base plan and paying several times more.
If you only remember one habit, it is this: model your realistic monthly volume, not the best case, and compare the AI-included cost rather than the headline. Tidio and Intercom are fine if you accept usage-based bills. Crisp is the predictable European pick once you can afford its AI tier. WoowBot is the cheapest at low volume if you will manage an API key. And Agentorie Chat, our tool, keeps the AI in the plan, offers a real free tier, and holds your data in your own database, for the buyer who values a predictable bill above all.
Whatever you choose, run the numbers for your own volume and a peak month before you commit. The cheapest pricing page rarely produces the cheapest invoice.
