Every customer service platform has “AI chatbot” in its marketing. But the actual AI capability varies enormously — from simple decision trees dressed up as AI to sophisticated GPT-4-powered conversation systems that genuinely understand natural language.
Here’s an honest breakdown of four options that are meaningfully different from each other.
The four options
Tidio — SMB-focused live chat and chatbot platform with Lyro AI for automated FAQ responses. Best known for value at small business price points.
Crisp — European-founded team messaging and chatbot platform with a strong free tier and broad channel support. Less AI-sophisticated than Tidio but cheaper at entry.
Intercom — Full customer communications platform with Fin AI, the most capable conversational AI of the pre-built options. Significantly higher price point.
Custom GPT chatbot — A chatbot built on OpenAI’s or Anthropic’s API, typically deployed via a chat widget like Botpress or a custom implementation. Full control over AI behaviour and knowledge base.
Pricing comparison
| Option | Free Tier | Entry Paid | AI Features | Monthly at Scale |
|---|---|---|---|---|
| Tidio | Yes (50 chats/month) | $29/month | Lyro AI included in Tidio+ ($79/month) | $79-100 |
| Crisp | Yes (unlimited chats, basic features) | $25/month (Mini) | Basic bot builder; AI add-on separate | $25-95 |
| Intercom | No | $74/month | Fin AI from $0.99/resolution | $150-400+ |
| Custom GPT | N/A | $2,000-6,000 build | Full GPT-4/Claude capability | $150-350 ongoing |
AI capability comparison
This is the most important dimension and where the differences are largest.
Tidio Lyro AI
Lyro is Tidio’s AI assistant, trained on a knowledge base you upload. It handles natural language questions about your business — answering from your FAQs, policies, and product information.
- Resolution rate: 55-65% for well-configured knowledge bases
- Language understanding: Good — handles variations in how customers phrase questions
- Multi-turn conversation: Basic — handles 2-3 turn conversations but struggles with complex multi-part queries
- Escalation: Smooth handoff to live chat agent when it can’t resolve
- Training: Upload your FAQ documents and product pages; Lyro learns from them
Best for: Businesses wanting AI FAQ deflection without enterprise pricing.
Crisp Bot
Crisp’s bot builder is primarily rule-based with some NLP (natural language processing) for intent detection. It’s not a full language model — it recognizes intent categories but doesn’t generate free-form responses from a knowledge base.
- Resolution rate: Lower than AI-based tools; works best for structured decision trees
- Language understanding: Intent recognition (limited) rather than full language understanding
- Multi-turn conversation: Good for defined conversation paths
- Escalation: Built-in live chat handoff
- AI capability: Crisp has introduced AI features in 2025 but the core is still primarily rule-based
Best for: Businesses that want a clean chatbot + live chat combination at a low price and don’t need sophisticated AI.
Intercom Fin AI
Fin is Intercom’s AI agent — the most capable of the pre-built options. It’s built on GPT-4 and trained on your knowledge base, support documentation, and conversation history.
- Resolution rate: Intercom reports up to 50% automated resolution; real-world rates for well-configured implementations range 40-55%
- Language understanding: Excellent — handles complex, multi-part questions and nuanced language
- Multi-turn conversation: Strong — maintains context across longer conversations
- Escalation: Seamless handoff to human agents with full conversation context
- Training: Trained on your help articles, URLs, and support history
Best for: Businesses wanting the most capable pre-built AI and willing to pay the premium. For a detailed breakdown of Fin’s capabilities and real-world performance, see our Intercom Fin AI review.
Custom GPT chatbot
A chatbot built directly on OpenAI (GPT-4o) or Anthropic (Claude) API, with a custom knowledge base and conversation design.
- Resolution rate: Depends entirely on knowledge base quality and conversation design — potential to exceed all pre-built options with proper configuration
- Language understanding: The full capability of GPT-4o or Claude — the best available
- Multi-turn conversation: Full capability
- Escalation: Custom designed — can be connected to any channel or system
- Training: Full control — you design what the AI knows and how it responds
- Integration: Can be connected to your order management system, CRM, inventory database — things pre-built platforms don’t access
Best for: Businesses that need full control over AI behaviour, custom integrations with internal data, or unique conversation requirements.

The decision framework
Choose Tidio ($79/month Tidio+) if:
- Budget is under $100/month
- You want AI FAQ deflection without enterprise complexity
- Fast setup is important
- Standard FAQ categories cover your support volume
Choose Crisp ($25-45/month) if:
- You want live chat + basic automation at the lowest possible cost

- Free tier is appealing for initial testing
- You don’t need sophisticated AI conversation
Choose Intercom (from $74/month) if:
- You want the most capable pre-built AI
- CRM-connected conversation context is important

- You want a single platform for chat, email, and customer communications
Choose a custom GPT chatbot if:
- You need AI that connects to your internal systems (order data, CRM records, inventory)

- You want full control over AI behaviour without pre-built platform constraints
- Technical implementation resources are available
