FAQ

Q: Can I use different AI models at different steps in the same workflow? A: Yes. Zapier lets you use different models for different steps — for example, a fast model for classification and a more powerful model for final output generation.

Q: Do I need my own API keys? A: Yes. You'll need API keys from Anthropic (Claude) or OpenAI (GPT). These are straightforward to set up and give you direct cost control.

Q: Is there a risk of client data being used to train AI models? A: Anthropic's Claude API and OpenAI's API both offer terms where your data is not used for training. Always use API access rather than consumer chat interfaces for client data.

Q: Can these workflows handle Chinese-language documents? A: Claude models perform exceptionally well with Chinese text — you can process Chinese-language documents and receive outputs in either English or Chinese.

Q: What's the learning curve for non-technical staff? A: Zapier's drag-and-drop interface is manageable for non-technical users. Most staff can build basic workflows after a 2–3 hour introduction session.
