Advizi AI — AI Thumbnail & Video Generator SaaS

Project Overview

Advizi AI is a personal SaaS project I built to help content creators generate visual content for YouTube and other platforms using AI. The platform brings thumbnail and video generation into one application, with user accounts, a credit-based usage system, and subscription billing.

The idea was to build more than a simple AI generation interface. I wanted to create a full-stack application where users could access generation features, use credits, and choose a plan that fits their needs.

What I Built

AI Thumbnail Generation Implemented AI-powered thumbnail generation for YouTube and other platforms, allowing users to create visual content and save or download their generated results.

AI Video Generation Built working video generation functionality alongside thumbnail creation, bringing two content generation workflows into one platform.

User Authentication Integrated Clerk to handle user authentication and access to the application.

Credit-Based Usage System Implemented a credit system with three plans:

Free: 20 credits

Pro: 80 credits

Premium: 240 credits

Subscription Billing Integrated Stripe for subscription and payment workflows connected to the platform's plans.

Media Handling and Error Monitoring Integrated Cloudinary for media handling and Sentry for error monitoring.

My Role:

I developed Advizi AI as a personal full-stack project, working across the frontend, backend, database, authentication, AI integration, and billing functionality.

The project involved bringing multiple services together into a single application, with React and TypeScript on the frontend and Node.js with Express.js on the backend.

Technology Stack

Frontend: React, TypeScript, Vite

Backend: Node.js, Express.js

Database: MongoDB

AI integration: Gemini API

Authentication: Clerk

Payments: Stripe

Media handling: Cloudinary

Error monitoring: Sentry

The Result

Advizi AI is a working AI content-generation application that combines thumbnail and video generation with authentication, usage credits, and subscription billing. It demonstrates my ability to develop a full-stack SaaS product and integrate AI services with the supporting systems needed for a user-facing application.
