Tidio vs Chatbase vs Crisp: Cheap AI Tools Compared (2026)

Three tools keep showing up on every "cheap AI chatbot for your website" list, and their sticker prices look almost identical: Tidio's Growth plan is about US$59 a month, Crisp is about US$95 a month for the entire workspace, and Chatbase's Standard plan is US$150 a month (vendor pricing pages, checked 2026-09-21). Then you turn the AI on, and the three bills stop looking anything alike. Tidio meters Lyro separately from your conversation allowance. Chatbase runs on credits whose cost changes with the model you pick. Crisp is the only one of the three that charges a flat fee per workspace rather than per seat — but its AI is the thinnest of the three.

This is an honest comparison of what each tool costs at real volumes, what each one does with languages beyond English, how each handles WhatsApp, and — the part the listicles skip — which one breaks first as your enquiry volume grows.

What do Tidio, Chatbase and Crisp actually cost in 2026?

Crisp is the most predictable, Tidio is the cheapest to start and the most likely to surprise you, and Chatbase is the most expensive per month at the tier most businesses actually end up on. All three publish their prices, which already puts them ahead of most of the market — but they publish three completely different billing bases, so the sticker prices are not comparable until you normalise them.

Here is the September 2026 picture, checked on each vendor's own pricing page on 2026-09-21:

Read that table by the billing basis row, not the price row. That row is the whole article.

Crisp charges per workspace. Add a second person, a third, a weekend helper — the platform fee does not move. That is genuinely unusual, and reviewers say so: G2 reviewers repeatedly credit Crisp with delivering comparable features "at a fraction of the cost" of Intercom or Zendesk, precisely because the flat workspace fee removes the per-seat tax (G2, 2026).

Tidio charges by billable conversations, with the AI on a second meter. Chatbase charges by credits, and a credit is not a conversation — it is a unit of model usage, so the same 500 questions cost more on an expensive model than a cheap one. Chatbase is the only one of the three where you cannot forecast next month's bill from this month's enquiry count.

For context on where these three sit in the wider market, the two big incumbents price on a third basis again: Intercom's Fin charges US$0.99 per outcome with a 50-outcome monthly minimum (Fin/Intercom, 2026), and Zendesk's AI agents bill roughly US$1.50 per resolution committed and US$2.00 pay-as-you-go (Coworker AI / eesel, 2026). We work through the full field — including where flat pricing fits — in our guide to the best AI customer service software for small business in 2026.

What is the difference between Tidio's Lyro, Chatbase credits and Crisp's MagicReply?

They are three different products wearing the same word. Chatbase is an AI answer engine first and an inbox second; Tidio is a live-chat inbox with an AI layer bolted on a separate meter; Crisp is a full helpdesk whose AI is mostly there to help your humans write faster.

Chatbase is the one built AI-first. You point it at your site or documents, it builds an agent over GPT-4o, Claude or Gemini, and you embed it. AI Actions connect to tools like Calendly, Stripe, Zendesk and Slack, so the agent can do something rather than only talk, and reviewers consistently describe it as the fastest way to get a polished AI agent onto a website. The recurring complaint is the economics: credits plus add-ons (branding removal alone is about US$99/mo) push real spend well above the sticker, and free agents are deleted after 14 days of inactivity (vendor documentation and G2 review themes, 2026). One caution before citing its rating: that 4.8/5 comes from only 19 G2 reviews (G2, 2026).

Tidio's Lyro is the AI layer on top of a mature live-chat product. The product itself is well liked — 4.6/5 across roughly 1,880 G2 reviews is a serious sample (G2, 2026) — and reviewers particularly praise how cleanly you can toggle between automation and a human taking over mid-conversation. The complaint is structural: there are effectively three meters running (billable conversations, the Lyro AI allowance, and Flows automation), and the free tier gives you just 50 conversations and 50 lifetime Lyro conversations, which is enough to demo and not enough to test.

Crisp's MagicReply is the weakest AI of the three, and Crisp reviewers say so in plain language. One G2 review states MagicReply "never ended up delivering on the promises… clunky… not even implemented in their own mobile app" (G2, 2026). Crisp's strength is the rest of the product — shared inbox, CRM, knowledge base, analytics, all at a flat workspace price. If you want a cheap helpdesk with a human team, Crisp is a strong buy. If you want the AI to carry the conversation on its own at 11pm, it is the wrong tool in this group.

That distinction matters more than any feature grid. Agent-assist AI makes your existing staff faster during office hours; autonomous AI answers when nobody is at the desk. If the enquiries you are losing arrive at 11pm on a Sunday, agent-assist does nothing for you.

Do Tidio, Chatbase and Crisp support WhatsApp, and what does Meta charge on top?

All three connect to WhatsApp on paid plans, but none of them absorbs Meta's per-message fees — and that is the single most under-stated line item in this entire category. Every platform price above excludes what Meta charges you per message, which is billed separately and varies by country and message type.

Meta moved the WhatsApp Business Platform from conversation-based pricing to per-template-message pricing on 1 July 2025 (Meta developer documentation, 2026). Four categories exist — marketing, utility, authentication and service — with marketing always charged and no volume discount. Rates are set by the recipient's country, so a Hong Kong number and a US number cost different amounts for the identical message. We break the full rate card down in our guide to WhatsApp Business API pricing in 2026 by country.

There is a deadline attached to that. From 1 October 2026, service messages — the free-form replies you send inside the 24-hour customer service window — become billable at the market's utility rate, with the first 1,000 service messages per month per phone number free (Meta developer documentation, 2026). Until that date, replying to a customer inside the window costs nothing. After it, high-volume inbound support on WhatsApp has a per-message cost attached for the first time since November 2024. If your plan is "we'll answer everything on WhatsApp because it's free," that plan has an expiry date.

There is also a rule change people misread constantly. Since 15 January 2026 (and 15 October 2025 for new accounts), Meta's WhatsApp Business Solution Terms prohibit AI providers from using the platform when a general-purpose AI assistant is the primary functionality offered (WhatsApp Business Solution Terms, 2026). Business-specific AI — customer service, order tracking, appointments, lead qualification — is expressly permitted, so none of these three is affected. But wiring a raw general-purpose model straight into WhatsApp yourself is no longer an option.

How well do these tools handle languages other than English?

All three answer in many languages through the underlying large language models, and none of the three is specialised for any particular one. That is fine for European languages and progressively less fine the further you get from English.

None of Tidio, Chatbase or Crisp lists Cantonese or Traditional Chinese as a focus area — all three fall into the "supported via a general multilingual model, not specifically tuned" bucket (vendor documentation review, 2026). In practice the model produces grammatical Traditional Chinese but will not reliably match the register a Hong Kong customer expects, sometimes answers a Cantonese question in Mandarin phrasing, and does not know local terms of art in your industry.

Three checks to run before you believe any vendor's language claim:

1. Test in the actual script and register your customers write in, not in textbook Mandarin typed into a demo box. Paste a real customer message from your inbox.
2. Ask a price question in that language. Pricing is where a weakly grounded model hallucinates first, and a wrong price in a customer's language is worse than no answer.
3. Check what happens on a mixed-language message — Cantonese with English product names, which is how a lot of Hong Kong and Singapore customers actually write. This is where thin multilingual support falls over.

The honest framing: for an English-speaking market, all three are adequate. For a market that mixes languages inside a single sentence, none of the three is built for you, and you should shortlist differently.

Which one breaks first as you grow?

Tidio breaks on the pricing cliff, Chatbase breaks on credit burn, and Crisp breaks on AI capability. All three are genuinely cheap at low volume — the question is which failure mode you hit first.

Tidio's break point is the jump from Growth to Plus. Growth runs about US$59/mo and covers roughly 250 to 2,000 billable conversations; the next tier, Plus, starts at US$749/mo, with Premium quoted around US$2,999 (vendor pricing, checked 2026-09-21). There is no mid-tier — a 12x step, and reviewers cite it as their single biggest frustration. Layer the Lyro meter on top and a steadily growing business pays US$90–150 all-in one month and faces a US$749 floor the next.

Chatbase's break point is credit burn. Because credits are consumed at a rate that depends on the model, heavier traffic on a better model drains the allowance faster than a linear conversation count suggests. Extra credits run about US$40 per 1,000, so overages are not catastrophic individually — they just arrive every month, and they arrive on top of Standard at US$150 or Pro at US$500 (vendor pricing, checked 2026-09-21). At about 2,000 conversations a month, realistic Chatbase spend lands somewhere between US$150 and US$500 depending entirely on which model you configured, which is a wide enough band to make budgeting awkward.

Crisp's break point is not money — it is the ceiling on what the AI can do. The flat ~US$95 workspace fee holds as you add people, which is exactly what you want. But if the reason you bought the tool was to stop losing after-hours enquiries, MagicReply's agent-assist positioning means you are still relying on a human being awake. Crisp scales your team's cost beautifully; it does not scale your coverage.

The pattern is not unique to these three. ManyChat cut its free tier from 1,000 active contacts to 25 on 2 March 2026 (BotPenguin, 2026), and Zendesk has auto-billed AI resolution overages with no cap since January 2026 (eesel AI, 2026). Cheap entry tiers are acquisition instruments and they get re-priced. Ask what the step above looks like before you build your process around the tool.

One more honest caution about the numbers everyone quotes. Vendor-marketed AI resolution rates are consistently higher than what deployments actually produce. Intercom markets an average 76% resolution rate for Fin, while its own Linktree case study reports Fin resolving 42% of conversations within six days (Intercom, 2026), and Zendesk's marketed 50–80% autonomous resolution has been contrasted with real-world figures nearer 10–20% (Richpanel, via review analysis, 2026). Whichever tool you choose, budget on your own numbers, not the headline. We unpack why that gap exists in containment versus resolution: the metric most teams get wrong.

Which should you pick, and when does a flat monthly fee make more sense?

Pick Crisp if you have humans and want a cheap, predictable helpdesk. Pick Chatbase if you want an AI agent live on your website this afternoon and you can tolerate a variable bill. Pick Tidio if you want a polished live-chat product with AI available and your volume will stay well inside the Growth tier. Those are the three honest recommendations, and none of them is "one tool is best."

What none of the three solves cleanly is the problem of paying for traffic. If you spend money on Google or Meta ads, an unanswered enquiry is not a delayed ticket — it is a purchased click that left without an answer, and in high-ticket service businesses one of those is worth HK$3,000 to HK$50,000. You are not buying deflection; you are buying coverage of the hours when the enquiries you already paid for arrive.

Against that job, the three tools here split cleanly. Chatbase covers the hours but bills by consumption, which means the months your ads work hardest are the months your software bill peaks. Tidio covers the hours until it doesn't, and then costs 12x. Crisp doesn't really cover the hours at all.

This is where flat-fee tools sit, including ours. Omago is an AI sales agent for businesses that pay for ads — it sits on the website and WhatsApp, answers in any language around the clock, qualifies the enquiry and books the appointment, on flat pricing of US$49–99 a month with no per-resolution or per-credit meter. It is not the cheapest entry point here; Tidio's Starter and Chatbase's Hobby tier both start lower. What it is, is a bill that does not move when your enquiry volume does, and one of very few tools you can test on your own site before paying. The full breakdown sits on our pricing page.

The decision rule I would actually use: if your enquiry volume is flat and low, buy on sticker price and take Tidio or Crisp. If your volume moves with your ad spend, buy on billing basis, not sticker price — because the consumption-priced tools charge you most in exactly the months you least want a surprise.

If you want to see how an AI agent handles your own business rather than a demo script, paste your URL on the homepage and ask it one of your customers' real questions.

Frequently asked questions

Is Tidio, Chatbase or Crisp the cheapest for a small business?

Crisp is cheapest at scale, Tidio is cheapest to start. Crisp charges a flat ~US$95 per month per workspace regardless of how many people use it. Tidio's Starter is about US$29/mo and Chatbase's Hobby is US$40/mo, but Tidio adds a separate Lyro AI meter from around US$32.50/mo and Chatbase's credits vary with the model you choose (vendor pricing pages, checked 2026-09-21). None of the three includes Meta's WhatsApp per-message fees.

Do these tools work with WhatsApp Business?

Yes — all three support WhatsApp on paid plans, with Chatbase offering it as a connector rather than a core channel. In every case Meta's per-message fees are billed separately and vary by country and message category, since the platform moved to per-template-message pricing on 1 July 2025 (Meta developer documentation, 2026). From 1 October 2026, service replies inside the 24-hour window also become billable at the utility rate after the first 1,000 per month per number.

Can Tidio, Chatbase or Crisp answer in Cantonese or Traditional Chinese?

They can produce answers in those languages through the underlying large language models, but none of the three lists Cantonese or Traditional Chinese as a specialised focus. Expect grammatically correct output with an imperfect register, occasional Mandarin phrasing in reply to Cantonese, and weaker handling of mixed Cantonese–English messages. Test with a real customer message before you commit.

Why did my AI tool bill go up when nothing changed?

Almost always because you are on a consumption meter rather than a flat fee. Credit-based tools like Chatbase bill by model usage, so a busier month or a change of model raises the bill; conversation-metered tools like Tidio can push you across a tier boundary — and Tidio's step from Growth (~US$59/mo) to Plus (from US$749/mo) has no intermediate rung. Per-resolution tools have the same shape: Intercom Fin charges US$0.99 per outcome (Fin/Intercom, 2026), so the bill rises as the AI succeeds.

Is it true that Meta banned AI bots on WhatsApp?

No — that is a misreading. Meta's WhatsApp Business Solution Terms prohibit AI providers from using the platform when a general-purpose AI assistant is the primary functionality, effective 15 October 2025 for new accounts and 15 January 2026 for existing ones. Business-specific AI for customer service, bookings, order tracking and lead qualification is expressly permitted, and none of the tools compared here falls foul of the clause.
