Key features

Pros & cons

Pros

  • Generous free plan includes API access, unlimited data sources, and white-label components — rare at this price point
  • Multi-model support — choose GPT-4, Claude, or GPT-3.5 per query; bring your own API key on Enterprise
  • Pre-built connectors for Notion, Zendesk, and Google Drive — minimal setup for documentation-heavy teams
  • White-label components available on all plans — embed a branded chat widget without upgrading
  • Model customization and fine-tuning available — adapt the AI to your specific terminology and tone

Cons

  • Free plan limited to 500 message credits/month — GPT-4 queries cost 3 credits each, so it runs out fast
  • No visible mid-tier pricing between Free and Enterprise — forces a jump to custom enterprise contracts
  • Credit system adds unpredictability to monthly costs depending on which model users trigger
  • Enterprise pricing lacks transparency — requires a sales conversation to understand actual costs
  • Smaller ecosystem compared to competitors like Intercom or Zendesk AI — fewer native integrations
