Pricing checked against each provider's official pricing pages and published rate cards as of September 2026. AI support pricing is usage-based and changes often — verify current rates before subscribing.
AI customer support tools have mostly moved to consumption-based pricing — you pay a seat fee for the underlying helpdesk, then a separate per-conversation or per-resolution charge for the AI agent itself. That makes these three genuinely hard to compare on price alone, since your actual bill depends entirely on ticket volume and AI resolution rate. Here's how Intercom Fin, Zendesk AI, and Tidio structure their pricing, and who each one actually fits.
Pricing at a glance
| Tool | Base plan | AI pricing | Best for |
|---|---|---|---|
| Intercom Fin | Seats from ~$19/agent/mo (promo) | $0.99 per resolution, $9.99 per qualification, 50-outcome monthly minimum | Mid-size teams wanting high resolution accuracy |
| Zendesk AI | Suite Team $55/agent/mo · Pro $115/agent/mo (annual) | ~$1.50/resolution committed, ~$2.00 pay-as-you-go, plus optional $50/agent Copilot | Teams already standardized on Zendesk |
| Tidio | Free · Starter $29/mo · Growth $59/mo | Lyro AI add-on from ~$32.50/mo (50 free conversations on lower tiers) | Small businesses and e-commerce on a budget |
Where each one wins
Intercom Fin is priced simply once you understand the model: a flat $0.99 per resolved conversation regardless of company size, layered on top of your Intercom seat cost. Intercom's own case studies report real-world resolution rates between 42% and 50%, which matters for forecasting — a support team fielding 2,000 tickets a month at a 45% resolution rate would pay roughly $891 in Fin charges alone, on top of seats. Since Salesforce's 2026 acquisition of the renamed "Fin" company, expect continued investment in resolution accuracy.
Zendesk AI makes the most sense for teams already running Zendesk for ticketing, since the AI layer builds on infrastructure you're likely already paying for. The pricing is the most layered of the three — base Suite plan, optional Copilot add-on, and a per-resolution meter — which makes it harder to predict your total bill without a pilot period, but it can work out efficiently at higher volumes where the included per-agent resolutions offset some of the metered cost.
Tidio is built for a completely different buyer: small businesses and online stores that need a chat widget with some AI on top, not an enterprise support platform. Its free plan and $29-59/month tiers are dramatically cheaper than the other two, though the catch is that Lyro AI isn't bundled into cheaper plans — it's a separate add-on, so a fully-loaded setup (Growth plan + Lyro + Flows automation) can land around $200/month rather than the advertised entry price.
The real lesson: model your own volume
None of these three have a price you can quote without knowing your ticket volume and expected AI resolution rate — that's true by design, since usage-based pricing is meant to scale with your actual support load. Before committing, run a free trial or pilot with each vendor using your real conversation volume, and calculate the fully-loaded monthly cost (seats + AI resolutions + any add-ons) rather than comparing the advertised starting prices.

The bottom line
If you're a small business or online store, start with Tidio — its pricing is the most transparent and the entry cost is low enough to test AI support without much risk. If you're a mid-size team that needs strong resolution accuracy and can tolerate per-conversation billing, Intercom Fin has the simplest pricing model of the enterprise-grade options. And if you're already deep in the Zendesk ecosystem, its AI layer is a natural add-on — just budget carefully, since it's the hardest of the three to predict a final bill for.
