Turn every movie experience into a beautiful ticket. Stubstack lets you photograph movie receipts, tickets, or posters β€” AI automatically identifies the film, pulls details from TMDB (the world's largest movie database), and helps you create a one-of-a-kind digital ticket to add to your collection. SNAP, PICK, COLLECT It's incredibly simple. Just take a photo of your movie receipt, ticket stub, or a poster. Our AI (powered by Gemini) analyzes the image and automatically extracts the movie title, showtime, screen number, and even your seat β€” all in seconds. 9 TICKET TEMPLATES Choose from 9 beautifully crafted templates β€” poster-style, backdrop-style, notched corners, perforated edges, and more. Combine them with official movie images for endless design possibilities. Every ticket is unique. COLORS EXTRACTED FROM THE FILM Our custom color extraction algorithm analyzes movie posters and stills to pull the most vibrant and expressive colors. These become the gradient background of your ticket, so each design naturally reflects the film's visual identity. 3D THAT FEELS REAL Tilt your device and watch your ticket respond. Using the gyroscope sensor, tickets rotate in real-time 3D with a glossy light effect that flows across the surface β€” as if you're holding a real collectible in your hand.
