AI PR & LinkedIn Content Engine

Objective: Build a Stripe-gated tool where subscribers submit articles, pitches, or posts and receive AI-generated PR pitches, LinkedIn posts, or AI-detection feedback via email.

What We’re Building

 3 n8n Workflows:

  1. Stripe subscription created: add email to n8n table, and send welcome email with form link
  2. Stripe subscription canceled: delete email from n8n table
  3. Form submission: verify email in the table, route to the correct GPT node, and send the HTML result email 

1 Form (Typeform – client provides account):

  • Email field
  • Tool dropdown (4 options):
    • Generate Pitch from Article
    • Check Pitch for AI Flags
    • Generate LinkedIn Post from Article
    • Check LinkedIn post for AI flags
  • Text area for input (article excerpt OR draft pitch/post) 

4 GPT Nodes (in main workflow):

  • One per tool, each configured with Justin’s Clear to Send framework + Robot Words Blacklist
  • AI Check nodes output: 1-10 score + explanation of flags

Email Outputs:

  • HTML formatted results via Outlook (client provides credentials)
  • Clean design with branding and background color
  • Delivered in <60 seconds 

Tech Stack:

  • Stripe (payments – client account)
  • Typeform (form + webhook – client account)
  • n8n (automation + GPT processing – client account)
  • n8n native database (subscriber table: email, subscription_id, status)
  • Outlook (email delivery – client credentials)
  • GPT-4o (content generation – client account) 

Client to Provide:

  • Clear to Send framework doc (for GPT prompts)
  • Robot Words Blacklist
  • 2-3 example outputs per tool 
  • Any additional context for GPT configurations
  • Stripe webhook access (account credentials)
  • Logo + brand colors for emails (if available)
  • n8n account + admin access
  • Typeform account credentials
  • Outlook email credentials 

Options

Add-On Option: Multi-Tier Subscription Model

Instead of one universal tool, subscribers choose between 3 tiers:

  1. Pitch Tools Only: Generate pitches + AI check pitches
  2. LinkedIn Tools Only: Generate posts + AI check posts
  3. Both Tools: All 4 features

 Additional Build Requirements:

  • Create 3 Stripe subscription products with separate pricing
  • Build 3 separate Typeforms (one per tier)
  • Add tier column to n8n database
  • Tier-specific welcome emails with correct form links
  • Tier verification logic (users only access tools they paid for)
  • Upgrade handling (Pitch Only – Both automatically grant new access)
  • 2 additional form processing workflows (LinkedIn workflow + Both workflows)

Additional Hours: 28 hours
