AI customer service tools stopped being a "bet" in 2026. The top platforms publish real resolution rates (percentage of tickets closed without a human agent touching them) and most now charge per resolved conversation instead of per seat. That pricing shift matters — it means you can estimate cost before committing instead of paying flat fees for unpredictable value.
I tested 8 of the most commonly-adopted tools across 2 test deployments: a small Shopify store (30 tickets/day) and a mid-size SaaS helpdesk (400 tickets/day). The list below is ordered by "how much you'd actually pay per month if you picked each one", cheapest to most expensive.
What it does: Lyro is Tidio's AI agent. It connects to your site, learns from your FAQ, and handles customer chat without a human. You can also use it as a traditional live chat + chatbot hybrid.
Free tier: 50 Lyro conversations/month. Decent for shops doing under 100 tickets/month total.
Paid: $49/month for 100 additional Lyro conversations, $250/month for the Plus plan with 200 conversations + advanced routing.
Best for: Shopify stores under 200 tickets/month. Tidio's Shopify app is rated 4.8 stars with over 1,800 reviews as of April 2026.
Resolution rate I got: ~35% on the Shopify test store. Most failures were around custom order status questions Lyro couldn't look up without API wiring.
What it does: Freddy is Freshdesk's built-in AI layer. It suggests answers to agents, auto-categorises tickets, detects sentiment, and runs a self-service bot on your help center.
Included in: Freshdesk Growth plan ($15/agent/month) and up. No per-resolution fee.
Where Freddy struggles: Freddy AI Agent (the autonomous ticket resolver) is a separate add-on that Freshworks prices on request. The included Freddy features are mostly assistive — they help your humans work faster, not replace them.
Best for: teams that already pay for Freshdesk and want to layer AI on existing agent workflows without changing platforms.
What it does: Gorgias is a Shopify-native helpdesk that reads your order data, subscriptions, and customer history directly. The AI can execute actions — issue refunds, update shipping addresses, cancel orders — not just answer questions.
Pricing: Starts at $10/month for 50 tickets. AI features are gated on the $60/month Basic plan (300 tickets) and up. AI-resolved tickets count as regular tickets against your quota.
Best for: Shopify and BigCommerce shops with 200-2000 tickets/month. Deep platform integration is the differentiator — a general chatbot can't cancel a Shopify order without custom code, Gorgias can.
Watch out for: Gorgias tracks usage in tickets, not conversations. A single conversation with 3 messages counts as 1 ticket, but if the customer comes back 48 hours later that's a new ticket.
What it does: HubSpot's AI chatbot sits on your Service Hub and uses your HubSpot knowledge base + CRM data to answer customers. It's included in Service Hub Professional and above.
Pricing: Service Hub Professional is $450/month for 5 users ($90/user/month). The AI features are bundled, no per-resolution fee.
Best for: companies already paying for HubSpot Service Hub. The chatbot isn't best-in-class on resolution rate, but the native integration with your HubSpot CRM (customer lifecycle, tickets, deals) is valuable if HubSpot is your source of truth.
What it does: Zendesk AI is a broad layer across their Support Suite. Includes intelligent triage, agent copilot (GPT-4 suggestions), article recommendations, automated summaries of long ticket threads, and a resolution bot on your help center.
Pricing: Advanced AI is a $50/agent/month add-on on top of Zendesk Suite ($55-$169/agent/month). For a 10-agent team on Suite Professional, AI brings total cost to ~$1,600/month.
Best for: teams of 10+ agents where agent productivity matters more than chatbot deflection. Zendesk AI's copilot-style features save experienced agents real time.
Resolution rate I got: ~40% on the SaaS helpdesk test, but that number depends heavily on how well-maintained your knowledge base is.
What it does: Fin (now "Fin 2", GPT-4 powered) is Intercom's autonomous AI agent. It reads your help center articles and answers customers without a human in the loop. Intercom publishes that Fin resolves around 50% of conversations on average across customers.
Pricing: $0.99 per resolution. A "resolution" is a conversation Fin closes without human handoff. You pay $0 for conversations it escalates.
Real math: 1000 resolved conversations/month = $990/month, on top of Intercom's base fees ($39-$139/seat/month).
Best for: SaaS companies doing >500 AI-resolved tickets/month. The per-resolution model aligns cost with actual value delivered. At smaller volumes, flat-fee competitors are cheaper.
Key feature: Fin can take actions through Intercom's "Tasks" — issue refunds, look up order status, update CRM fields — if you wire them up. This is the feature that makes Fin worth $0.99/resolution over cheaper flat-fee bots.
What it does: Ada is an enterprise chatbot platform built for companies with custom workflows, multilingual support (50+ languages out of the box), and strict compliance requirements. Supports voice, chat, email, and social channels.
Pricing: No public pricing. Enterprise contracts typically start at $24,000/year and scale from there.
Best for: companies with >$5M in revenue, complex support operations, compliance needs (healthcare, finance), and multi-language audiences. Ada's "Reasoning Engine" can handle multi-step workflows like "check my order, refund it if eligible, update my shipping address" in one conversation.
Typical ROI claim: Ada publishes customer stories showing 60-80% automated resolution rates. Our test didn't run long enough to reach those numbers — they require significant content investment in the Ada knowledge base.
What it does: Einstein AI layer integrated into Service Cloud. Includes case classification, agent copilot, knowledge article recommendations, and Einstein Service Agent (the autonomous bot).
Pricing: Einstein Service Cloud starts at $75/user/month. Einstein Service Agent (the autonomous AI) is charged at $2/conversation.
Best for: companies where Salesforce is already the source of truth for customer data. Einstein's power is its CRM integration — it knows the full customer lifecycle, not just the current ticket.

Most people pick the wrong one because they shop by features. Pick by this decision tree instead:
Every vendor on this list will tell you their AI "resolves 70-80% of tickets". In practice:
Our AI for Sales Teams guide covers Outreach Kaia, Gong AI and other tools that target the revenue side of the same conversation.
Read the sales AI guideIntercom publishes that Fin AI resolves around 50% of conversations autonomously on average across customers. Our own testing put Ada at 45-55% depending on how much knowledge base content was available, and Tidio Lyro at 30-45% for small e-commerce shops. Anything claiming "over 80% resolution" out of the box is marketing — real numbers depend heavily on how well your knowledge base is written.
Only if your volume is predictable. Fin at $0.99 per resolved conversation costs $990 per 1000 resolutions. Zendesk AI at $50/agent/month with 5 agents is $250 flat regardless of volume. Below ~250 AI-resolved conversations per month, agent-based pricing is cheaper. Above that, per-resolution wins.
Tidio Lyro has a free tier that includes 50 Lyro conversations per month — enough for small Shopify stores to test. Gorgias starts at $10/month but only includes 50 tickets. Freshdesk Freddy is included free up to the Growth plan ($15/agent/month). For pure testing, start with Tidio free.
Yes, if you use one with deep platform integrations. Gorgias (Shopify-native) and Intercom Fin can both execute refund actions autonomously via Shopify/BigCommerce APIs. Zendesk AI and Ada support this via custom actions but require setup work. Generic chatbots without platform integration can only answer questions — not act on them.
