Turn a Rough Product Idea into a Requirements Brief with AI Chat

I built a lightweight n8n AI workflow that turns a rough product idea into a structured requirements brief through chat.

Workflow JSON:
I cannot upload attachments yet because this is a new forum account, so I shared the workflow JSON here:
[GitHub Gist link]

It is designed as a simple product discovery helper for founders, consultants, no-code builders, and automation builders.

What it does:

  • Receives a rough product idea through n8n chat

  • Extracts structured product intake data

  • Applies a lightweight requirements framework

  • Generates a requirements brief

  • Parses and validates the AI output

  • Returns a markdown brief in the same chat

Nodes used:

  • Chat Trigger

  • Code nodes

  • OpenAI nodes

  • Sticky Notes for setup and documentation

Output includes:

  • Project summary

  • Problem statement

  • Target users

  • Goals

  • Assumptions

  • Functional requirements

  • Non-functional requirements

  • MVP scope

  • Out of scope

  • Open questions

  • AI-generated disclaimer

Setup:

  1. Import the workflow JSON.

  2. Add your OpenAI credential to both OpenAI nodes.

  3. Open the chat panel.

  4. Paste a rough product idea.

  5. Review the generated requirements brief.

  6. Adapt the prompt, framework profile, or markdown format for your use case.

Sample input:
I want to build a simple web app for independent fitness coaches. It should help them manage clients, create workout plans, track progress, and send weekly check-ins. Target users are solo fitness coaches and small personal training studios. Keep it mobile-friendly, simple for MVP, and GDPR-friendly.

Disclaimer:
This brief is AI-generated from the provided input. It is intended as a starting point for product discovery and requirements discussion, not as a final specification.

I would appreciate feedback from the community, especially around output quality, prompt structure, and how to make the workflow easier for beginners to use.

Cheers
