Inspiration

Small businesses and creators struggle to plan engaging, multi-platform social campaigns because they lack the time and tools to manage everything content creation, scheduling, competitor research across multiple channels. We envisioned an AI-powered assistant that turns raw product details into ready-to-launch marketing campaigns in seconds.

What It Does

Our platform ingests campaign details: budget, product info, audience, even audio inputs via Gladia and uses Claude to instantly generate post titles, descriptions, schedules, and formats for Twitter, Instagram, LinkedIn, and more.

It also integrates Apify to scrape competitor data for insights and trends, so campaigns can be benchmarked against market activity. All results are saved for review or direct publishing, streamlining the entire campaign workflow.

How We Built It

Frontend: Next.js with Stytch for seamless passwordless authentication and user profiles
Backend: Express.js + PostgreSQL (AWS RDS) for campaigns, assets, and analytics
AI Layer: Anthropic Claude for content generation, Gladia for speech-to-text, Apify for competitor intelligence

Challenges We Overcame

Migrating from Auth0 to Stytch while preserving SSO and security
Handling strict JSON parsing from LLM outputs with schema validation
Configuring SSL, connections, and migrations on AWS RDS
Fixing CORS issues between Next.js frontend and Express backend
Normalizing and merging competitor data from Apify into campaign workflows

Accomplishments We’re Proud Of

End-to-end pipeline: from campaign setup → audio input transcription → competitor analysis → AI-generated content → review-ready campaigns
Reliable integrations producing valid, structured campaign data
A polished, responsive UI with Chakra’s theming for quick deployment
