About the project
What is Gathrly?
This project involved building a next-generation AI SaaS platform that transforms event photography through AI-powered image and video generation. Designed primarily for venues, event organizers, and entertainment businesses, the platform offers a self-service AI photo booth where guests can capture a photo, and instantly generate AI-enhanced portraits, stylized images, or short video loops using pre-defined artistic templates. The platform was built as a scalable SaaS solution integrating AI image generation, AI video transformation, and automation pipelines, all powered by Gemini API.
The problem
What was slowing them down.
- 01
AI-generated portraits and videos
Allows attendees to instantly create AI-generated portraits and videos in different artistic styles.
- 02
Automated Processing
Reduces operational overhead with automated processing and cloud storage.
- 03
New Revenue Stream
Provides a new revenue stream for venues through photo booth engagement.
- 04
Easy Access to AI Content
Ensures guests can easily access and download their AI-generated content directly to their phones.
The solution
What we built.
AI Photo Booth Interface
Guests take a photo directly from the booth’s camera and preview AI-generated results in real-time.
AI Image & Video Generation
Supports image-to-image, image-to-video, and video-to-video generation using the Gemini API.
Pre-Built Templates
Themed templates (Elegant, Celebration, Psychedelic, Editorial, etc.) for one-click stylization.
Centralized Cloud Storage
All generated content is securely stored and mapped to user entries via phone number.
Automated Delivery System
After submission, users receive a personalized link via both SMS and email to view and download their AI creations.
Revenue Sharing Model
Built-in admin dashboard for automated revenue distribution between venues and platform administrators.
Secure SaaS Infrastructure
Integrated authentication, scalable cloud storage, and API usage management.
