The AI chatbot market in 2026 is split into two worlds. Enterprise platforms like Intercom and Chatbase charge $100 to $400 per month for SOC 2 audits, voice channels, and Salesforce integrations. Small-business platforms like PopABot, Tidio and ManyChat charge $0 to $50 for the things SMBs actually use: lead capture, SMS notifications, appointment booking, and WhatsApp handover.
If you run a trades business, a hotel, a clinic, an agency, or any company under 50 staff, you almost certainly want the second group. This guide compares all seven on verified pricing as of May 2026, explains why chatbot pricing is so deliberately confusing, and tells you which one to pick based on what you actually do.

1. PopABot, best for lead capture, SMS, and small-business pricing
The pitch in one line: a no-code chatbot that turns website visitors into phone calls, bookings, and SMS-notified leads, on flat monthly pricing.
Pricing (May 2026):
- Starter: $0 (300 messages/mo, 1 chatbot, no expiry)
- Essential: $19/mo (1,000 messages, 2 chatbots, SMS, calendar, branding removed)
- Pro: $49/mo (8,000 messages, 5 chatbots, 50 SMS, A/B testing, agency mode)
- Enterprise: custom (30,000 messages, 999 chatbots, 500 SMS)
What's good:
- SMS lead notifications built into every paid tier, no add-on, no Twilio account to wire up
- Multiple chatbots included (2 / 5 / 999), where most competitors give you one
- Native Google Calendar booking with availability rules and SMS confirmation
- WooCommerce product search, hosted-link mode (no website needed), and QR codes for print
- Scored assessment chatbots (a quiz that delivers a verdict plus a downloadable PDF)
- Replies in any language the visitor writes in. GPT-4.1 auto-detects the browser language and answers in that language with zero setup. A Japanese visitor types in Japanese, gets a Japanese reply. A Vietnamese visitor types in Vietnamese, gets a Vietnamese reply. Works for around 100 languages with no translation plugin.
What's limited:
- Admin dashboard is translated into 9 languages (English, French, Spanish, German, Dutch, Italian, Portuguese, Turkish, Polish), though the chatbot itself is language-agnostic
- No voice or telephony channel
- No SOC 2 Type II certification yet
- Newer brand, smaller customer base than the incumbents
Best for: tradespeople, hotels, clinics, dental and beauty practices, agencies managing several client sites. Skip if: you need HIPAA or SOC 2 today.
2. Chatbase, best for enterprise compliance and voice support
Pricing: Free (50 msgs, 14-day idle deletion), Hobby $32, Standard $120, Pro $400, Enterprise custom. Removing the "Powered by Chatbase" badge costs $1,188 per year as a separate add-on. Additional agents are $300 per year each, even on paid plans.
What's good: SOC 2 Type II, GDPR, HIPAA on Enterprise. Voice and telephony from Standard. Native Salesforce, Zendesk, Stripe, Make integrations. AI Actions framework for tool calling. Used by IHG, National Grid and roughly 10,000 businesses. Markets "80+ languages with auto-detect," which is the same underlying LLM capability PopABot has, priced four times higher.
What's limited: single agent on every paid plan unless you pay extra. No SMS. No native appointment booking (Calendly or Cal.com only). Removing branding is a four-figure add-on. Message credits are consumed faster than you'd expect: one user turn can cost multiple credits if it triggers an action.
Best for: mid-market support teams replacing Zendesk Answer Bot.
3. Tidio, best for live chat that wants light AI on top
Pricing: Free (50 conversations), Starter $24.17/mo, Growth from $49.17/mo, Plus from $749/mo. Lyro AI agent is a separate add-on starting at $32.50/mo for 50 AI conversations on top of your plan.
What's good: hybrid live-chat plus chatbot product. Tight Shopify and WordPress integrations. Ten seats on every paid plan, which is rare. Lyro AI handles natural-language tickets when humans are offline.
What's limited: AI conversations are billed separately from "billable conversations," creating two simultaneous meters running against the same chatbot interaction. The jump to Plus at $749/mo to unlock branding, departments and OpenAPI is a steep cliff.
Best for: ecommerce stores that want a single tool for live chat, ticketing, and bot fallback.
4. Intercom, best for funded startups with budget
Pricing: Essential $29 per seat per month, Advanced $85, Expert $132. Fin AI Agent costs $0.99 per resolved outcome on top of seat fees. A two-seat team running Advanced with 500 Fin resolutions per month costs $170 plus $495 = $665 per month.
What's good: the category-defining product. Best-in-class help desk. Fin is genuinely strong at resolution rate. SOC 2, HIPAA, and an Early Stage program with up to 90% off if you're a venture-backed startup.
What's limited: per-outcome pricing makes budgeting impossible. The more useful your bot is, the more you pay. Add-ons (Copilot $29 per agent, Proactive $99/mo, Pro analytics $99/mo) stack quickly.
Best for: Series A and later SaaS companies with a customer success team. Skip if: you're price-sensitive or your conversion volume swings month to month.
5. ManyChat, best for Instagram and Facebook DM automation
Pricing model: per contact (MAU). Free up to 1,000 contacts on Facebook and Instagram automation. Paid plans scale with contact count. SMS and email channels are paid add-ons. (Specific 2026 dollar figures could not be verified against ManyChat's live pricing page; pricing has historically started around $15/mo for the Pro plan.)
What's good: dominant on Instagram DMs and Facebook Messenger automation. Visual flow builder. Comment-triggered DMs work well for creators.
What's limited: built for social DMs, not for a website widget. AI capabilities are bolted on, not central. Pricing scales with contact list, so a viral post can trigger a plan upgrade.
Best for: creators, influencers, ecommerce brands running social ads.
6. AI SmartTalk, best for document-grounded Q&A
Pricing: Pro €29/mo, Business €79/mo, Enterprise custom. Pricing model caps indexed documents rather than pages scraped, which is unusual.
What's good: strong RAG (retrieval-augmented generation) over uploaded knowledge bases. Clean French and European market presence.
What's limited: focused on Q&A, weaker on lead capture, no native booking, no SMS. Single chatbot per account on Pro.
Best for: internal knowledge bases, SaaS support sites with heavy documentation.
7. Voiceflow, best for developers building custom flows
Pricing: sales-contact only as of May 2026. Public pricing was removed from the website. Free trial is available with limits.
What's good: most powerful flow designer in the market. Multi-model (OpenAI, Anthropic, Google) with model comparison built in. Strong API. Voice and chat in one canvas.
What's limited: no published pricing means no budget control until you talk to sales. Built for builders, not for a plumber who wants a chatbot today.
Best for: developers, agencies building bespoke bots for clients.
Why AI chatbot pricing is so confusing (and how to read it)
Almost every platform on this list uses a different metering unit. That's not an accident. Confusing pricing makes head-to-head comparison hard, which protects margins. Here's the decoder.
Model 1: "message credits"
Used by: Chatbase.
A credit is consumed per message the bot sends back to the user, plus extra credits when actions or tools fire. A single user question that triggers a knowledge-base lookup, a calendar check and a confirmation message might burn three or four credits. Your stated 4,000-credit cap can run out in roughly 1,000 real conversations, not 4,000.
How to read it: divide the credit count by 3 to estimate real conversations.
Model 2: "billable conversations" plus an AI add-on
Used by: Tidio.
A billable conversation is any unique customer thread within a 24-hour window. AI conversations are metered separately on top, via the Lyro add-on. Two meters, same bot.
How to read it: check whether AI is included or sold separately. With Tidio, it's separate.
Model 3: seats plus per-outcome
Used by: Intercom Fin.
You pay per support agent seat ($29 to $132) plus $0.99 every time the AI bot resolves something. The more effective your bot, the higher your bill. Volume discounts exist but aren't published.
How to read it: forecast monthly bot resolutions and multiply by $0.99. Add seat costs. Under 200 resolutions/mo it's affordable, over 1,000 it stops being SMB pricing.
Model 4: per contact (MAU)
Used by: ManyChat.
You pay based on how many unique contacts the bot has interacted with this month. A viral Instagram reel can push you into a higher tier overnight.
How to read it: check the contact limit, not the message limit. Contacts roll forward; messages don't.
Model 5: hidden, contact sales
Used by: Voiceflow (as of May 2026), most Enterprise tiers.
The honest read: if there's no public price, the price is "whatever you'll pay." You will negotiate. Expect a 6-month sales cycle for enterprise contracts.
The case for flat monthly pricing
The clearest model is the simplest one: a flat monthly fee with a stated message cap that doesn't move. PopABot prices this way: Essential is $19, gives you 1,000 messages, two chatbots, SMS, calendar and removed branding. Pro is $49, gives you 8,000 messages, five chatbots. No add-ons for branding removal. No per-resolution surcharges. No second AI meter on top of the conversation meter. No surprise jumps because you went viral.
If you can fit your business into a flat-rate plan, you almost always should. The total cost of a chatbot isn't the sticker price, it's the forecast accuracy of that sticker price. Per-outcome and per-contact pricing fail this test by design.
How to choose: the 5-question framework
- Where do your visitors come from? Website only: PopABot, Chatbase, Tidio. Mostly Instagram or Facebook: ManyChat. Mix: PopABot with WhatsApp handover, or Tidio.
- Do you need SMS notifications to your phone when a lead lands? Yes: PopABot is the only one in this list with it built in. Others require Zapier plus a Twilio account, which adds $20 or more per month.
- Are you booking appointments? Yes, into Google Calendar with availability rules: PopABot. Yes, via a Calendly link: any of them.
- How many websites or clients are you running? One: any. Multiple: PopABot Pro (5 bots) or Enterprise (999), or Voiceflow agency tier. Chatbase, Tidio and Intercom charge per extra agent.
- What's your compliance posture? SOC 2 or HIPAA today, non-negotiable: Chatbase or Intercom. Standard GDPR encryption is enough: any of them.
