Abstract
Nexus is a self-serve AI intelligence SaaS at $199–399/month. Eight AI modules — Terminal, Content Engine, Strategist, AI Scanner, Aura, SEO Engine, SMM, and Synapse — share a credit-gated access layer with per-tenant Cognito isolation, Stripe billing, and Google OAuth for GBP and GSC data.
Problem
Small and mid-size businesses need AI-assisted content, reputation management, SEO analysis, and social media tools but can't justify enterprise AI contracts or the overhead of stitching together separate tools. A unified platform at a predictable monthly price solves the budget problem; per-module credit gating lets usage-heavy tenants pay more without requiring per-seat pricing.
Approach
Gate stack
The gate stack flows AuthGate → SubscriptionGate → OnboardingGate → Dashboard. Every module route checks credits before executing via a shared `checkCredits` / `deductCredits` pair backed by atomic DynamoDB decrements.
Usage logs and monthly summaries persist in the same table.
Tenant and billing
Tenant isolation runs through a `custom:tenant` Cognito claim validated in every API route. Google OAuth (GBP + GSC) is per-tenant with tokens stored in DynamoDB and auto-refreshed by the Python Lambda.
Stripe manages the billing lifecycle: checkout, trial, conversion, payment failure, and cancellation, each mapped to a DynamoDB subscription status.
Model routing
AI modules call Claude via Bedrock (Sonnet 4.6 for most tasks, Opus 4.6 for scan analysis). Document parsing (PDF, DOCX, TXT, MD, CSV) runs in a separate Python Lambda.
