Been building tools with Pickaxe for a while now and this is the question that comes up the most from new builders. Here is the simple version.
**Use a Form when:**
- You need structured data back (lead qualification, intake forms, assessments)
- The user should answer specific questions in a particular order
- You want to control the conversation flow completely
- You need the output formatted consistently every time
Forms are predictable. You define the questions, the user fills them in, and you get clean structured data out the other end. If you are building something that feeds into a CRM, generates a report, or creates a deliverable, start with a Form.
**Use a Chatbot when:**
- The user needs to explore or ask follow-up questions
- You are building a knowledge base assistant or FAQ bot
- The interaction is open-ended and conversational
- Different users might need different things from the same tool
Chatbots are flexible. They handle the unexpected well. If someone asks a question you did not anticipate, the chatbot can still give a useful answer (especially with a good knowledge base behind it).
**The tricky part: when you need both**
A lot of builders start with a chatbot and then realize they actually needed a form with a conversational feel. If that sounds like you, start with the Form type. You can make forms feel conversational through your prompt instructions while still getting the structured output you need.
The reverse is harder. Starting with a chatbot and trying to force structured output is fighting the tool instead of working with it.
**My rule of thumb**
If the answer to your question is always the same shape (name, email, 3 bullet points, a score), go Form. If the answer depends entirely on what the user asks, go Chatbot.
And if you are building client-facing tools and want to compare notes with other builders, we have a community that does exactly this every week in Pickaxe Pro Builders: Pickaxe Pro Builders
What have you found works better for your use case? I am curious what patterns other builders are seeing.
