# Twin Pics > Daily AI image challenge for K-12 classrooms. Students write prompts to generate AI images and compete for the highest similarity score against a reference image. Twin Pics is an AI literacy tool used by teachers in schools across the US, Canada, Australia, UK, and 40+ countries. It teaches descriptive writing, visual literacy, and AI skills through a daily game format. ## How It Works 1. A new challenge image is posted every day 2. Students write a text prompt (max 100 characters) describing the target image 3. AI generates an image from their prompt (using FLUX.2) 4. AI scores how similar their image is to the target (0-100 scale) 5. Students compete on classroom and global leaderboards ## For Teachers - Zero prep required - new challenge every day - Create a classroom with a single click - Students join with just a word code and nickname (no accounts needed) - Real-time classroom leaderboard - Works on any device (Chromebooks, iPads, phones) - Free tier includes 1 classroom with unlimited students ## Key Pages - Homepage & Game: https://twinpics.ai - For Teachers: https://twinpics.ai/for-teachers - Pricing: https://twinpics.ai/pricing - Blog: https://twinpics.ai/blog - Join a Classroom: https://twinpics.ai/join ## Topics - AI literacy for K-12 - AI image generation in education - Classroom engagement activities - Descriptive writing exercises - STEM and digital literacy - Bell ringer activities - Fast finisher activities ## Contact - Creator: Chris Sev - Twitter: https://x.com/chris__sev - Website: https://twinpics.ai
