About AI API costs
CanForm's message generation and form-discovery judgment call one of Anthropic (Claude), OpenAI (GPT), or Google (Gemini). These API costs are billed directly to you by each provider through your own API key, and are not included in CanForm's monthly price. You can reduce cost by using a lighter model for judgment tasks and a stronger model only for message generation. See the AI settings documentation for more (Japanese-only page for now).
