FAQ
How is ERP integration handled?
The prompt asks for a sync service that treats the ERP as the single source of truth, plus an idempotent webhook consumer.
Isn't customer-specific pricing complicated?
The price list + customer group + quantity tier model comes ready in the data schema, and the CTO persona provides an example table structure.
Which tools can I paste the generated prompt into?
Claude Code, Cursor, Windsurf, v0, Lovable, Bolt and ChatGPT. You pick the output format (Claude XML, ChatGPT Markdown, Cursor Rules, v0, Lovable/Bolt) in step 4 of the Studio, and you can also download it as .cursorrules or CLAUDE.md.
Is it free?
Yes. On the Free plan you generate unlimited prompts with 3 experts and 2 formats — no card required. 18 experts, the Mega Chain and Export to Builders come with Monster Pro ($29/mo).
