A new kind of social feed is gaining traction, and it's not about watching - it's about playing. Gizmo, the TikTok-style app from New York startup Atma Sciences, has quietly racked up 600,000 installs in less than six months by letting anyone create interactive mini-apps using nothing but AI prompts. The app's December growth alone - 235,000 downloads - signals a fresh appetite for creativity tools that blur the line between coding and casual creation.
Gizmo is rewriting the rules of what a social feed can be. Instead of passively scrolling through videos, users swipe through a vertical stream of interactive mini-apps - digital toys that respond to taps, swipes, drags, and drawing. Think puzzles, animated art, quirky memes, and experiences that defy easy categorization. The twist? Anyone can create them using nothing but text prompts.
The app comes from Atma Sciences, a New York startup co-founded by Rudd Fawcett, Brandon Francis, CEO Josh Siegel, and CTO Daniel Amitay. The team raised a $5.49 million seed round from First Round Capital and others last year, according to PitchBook data. Their mission, as stated on their playfully interactive website, centers on "combining powerful technology with simple, elegant foundations."
What makes Gizmo stand out in the increasingly crowded vibe-coding space is its refusal to make users think like programmers. Other platforms like Anything focus on utility - building micro-apps for specific tasks. Gizmo takes a different path, prioritizing fun over function. You're not building a productivity tool. You're creating something that makes someone smile, or think, or poke their screen repeatedly just to see what happens.
The creation process is disarmingly simple. Type out what you want in natural language - "make a quiz about 90s cartoons" or "create a bouncing ball that changes colors" - and Gizmo's AI coding technology generates the underlying code, renders it visually, and checks that everything runs smoothly. The company uses both AI and human moderation to vet apps for safety, according to its .
