Problem Solved

Modern businesses face significant challenges with sophisticated AI-generated spam that bypasses traditional bot detection:

  • High volume spam submissions (10-15+ daily for typical small businesses)
  • Legitimate customer requests buried in spam
  • Traditional captchas ineffective against AI-generated content
  • Need for intelligent content classification beyond simple bot detection

Key Features

Core Functionality

  • AI-Powered Classification: Advanced machine learning models identify spam patterns in form submissions
  • Real-time Processing: Instant spam detection without user experience delays
  • Easy Integration: Simple embedding process for existing websites
  • Dashboard Management: Clean interface for reviewing and managing submissions

Technical Features

  • Authentication & Billing: Complete user management via Clerk integration
  • Embeddable Forms: JavaScript widget for seamless website integration
  • API Access: RESTful API for custom implementations
  • Analytics: Submission tracking and spam detection metrics

Technology Stack

Current Architecture

  • Frontend: NextJS with shared Zod schema validation
  • Authentication: Clerk for user management and billing
  • API Design: Traditional REST endpoints with Zod schema sharing
  • Database: Railway-hosted PostgreSQL with local Docker-compose development
  • Deployment: Railway platform with CI/CD pipeline
  • Infrastructure: Full production monitoring and scaling

Technical Architecture Decisions

Framework Philosophy: Deliberate simplification over complex meta-frameworks - NextJS usage focused on core strengths without over-engineering - Consideration for migration to Vite + separate backend for explicit separation - Evaluation of tRPC integration for improved type safety and developer experience

Database Strategy: Infrastructure over abstraction - Migration from Supabase to Railway-hosted PostgreSQL for better control - Docker-compose for local development consistency - Trade-off of Supabase UI convenience for database ownership

API Design Evolution: Type safety and maintainability focus - Current shared Zod schemas providing validation across frontend/backend - Potential tRPC integration inspired by successful agents platform implementation - Full-stack type safety as development velocity multiplier

Business Model

  • SaaS Subscription: Tiered pricing based on form volume
  • Freemium Option: Free tier with branding requirement for rapid distribution
  • API Integration: Flexible pricing for high-volume custom implementations

Market Position

Form Spam Filter addresses a clear market gap where existing form platforms lack AI-specific spam detection:

  • Google Forms relies primarily on Captcha

Distribution Strategy

Primary Channels

  • ChatGPT App Store: Leveraging AI ecosystem for targeted distribution
  • Direct Marketing: YouTube Shorts and social media content
  • Partnership Integration: Potential integrations with form platform providers

Growth Approach
