## Warned against

- Intercom Fin AI Agent: 5 of 24 labels negative. "Intercom has one of the best AI agents on the market, but its $0.99-per-resolution pricing model ... is heavily criticized by small-to-medium businesses." (Gemini 3.1 Pro, negative prompt)
- Zendesk AI Agents: 3 of 10 labels negative. "It is incredibly powerful but often requires a steeper learning curve and a higher total cost of ownership than simpler tools." (Gemini 3.1 Pro, comparative prompt)
- Ada: 4 of 18 labels negative. "Ada is the clearest named example I found: G2 reviewers consistently flag implementation as "a huge, time-consuming project," making it better suited to large CX programs than smaller teams" (Claude Opus 5, negative prompt)
- Chatbase: 2 of 4 labels negative. "they are less clearly positioned as full customer-support suites than Tidio" (Perplexity Sonar Pro, budget prompt)
