Meet Gizmo: a TikTok for interactive, vibe-coded mini apps

Gizmo is a new mobile app that offers a fresh take on interactive media. Created by the startup Atma Sciences, it functions like a TikTok-style feed but for small, playable applications. Instead of passively watching videos, you actively engage with these mini apps, called Gizmos. You might poke, swipe, tap, draw, or drag on the screen to interact with digital toys, puzzles, memes, art, or animations.

A key feature is that anyone can create these Gizmos without knowing how to code. You simply type an idea using natural language as an AI prompt. The app’s AI coding technology then generates the necessary code to bring your idea to life, visually rendering it to ensure it works properly. All apps are vetted through a combination of AI and human moderation for safety.

The feed is designed to be engaging and playful. You can like and comment on creations, and even remix existing Gizmos to make your own version. The app hails from New York-based Atma Sciences, co-founded by Rudd Fawcett, Brandon Francis, CEO Josh Siegel, and CTO Daniel Amitay. The company raised a $5.49 million seed round last year from First Round Capital and others. The founders were not available for comment for this story.

Gizmo stands out in the vibe coding space by focusing on creation for fun rather than utility. Its feed is filled with diverse and creative mini apps, creating an experience that feels like a mix between TikTok and interactive 3D design apps. However, Gizmo keeps creation simple and prompt-based, unlike some platforms that introduce more complex programming languages.

In practice, the app is very easy to use. You type a prompt, see the result, and can modify it as needed. Finished creations can be shared to Gizmo’s feed, messaged to friends, or posted to social media via a unique link.

According to market data, Gizmo has approximately 600,000 installs, with about half coming from the United States. It launched quietly less than six months ago and saw significant growth toward the end of last year, with 235,000 downloads in December alone. That month represented 39% of its total installs. Growth from October to December was 312%, with strong month-over-month increases. The app is available for both iOS and Android.
