Gizmo, a TikTok-like app for vibe-coded mini applications, is offering a new way to create interactive media. The relatively new mobile app from the startup Atma Sciences lets anyone create experiences using text, photos, sound, and touch, which are then displayed in a vertical feed, similar to TikTok or Reels. But unlike traditional short-form video apps, you don’t just watch and scroll in Gizmo — you play.

Depending on the type of “Gizmo” you encounter, you might poke the screen, swipe, tap, draw, drag, and more to interact with the mini app. These Gizmos aren’t just games but are more like digital toys — things that could include interactive puzzles, memes, art, animation, or anything else a creator can dream up.

The result is an engaging, playful feed, where you can like and comment on the tiny creations and even remix existing Gizmos to create your own version, if you choose.

What’s more, you don’t need to know how to code or even vibe code to get started. Instead, you can simply type out an AI prompt to explain your idea using natural language.

The app then leverages AI coding technology to turn your idea into an interactive experience by generating the code that makes it work. As part of this process, Gizmo will also render your idea visually to ensure that each app functions properly and runs smoothly. Apps are also vetted using AI and human moderation to ensure user safety, a company FAQ notes.

Gizmo hails from a New York-based startup called Atma Sciences, co-founded by Rudd Fawcett and Brandon Francis, along with CEO Josh Siegel and CTO Daniel Amitay. The company last year raised a $5.49 million seed round from First Round Capital and others, according to data from PitchBook. On the company’s website (which is also silly and interactive), the team explains their focus is on combining “powerful technology with simple, elegant foundations,” starting with their creativity app, Gizmo.

None of the company’s founders responded to requests for an interview when TechCrunch reached out, through multiple emails, requests to investors, and via LinkedIn. We were told by one investor that the team isn’t yet ready to do press. (Sorry!)

TechCrunch was drawn to Gizmo because of the app’s potential for growth and its unique approach to the vibe coding space (and a rare recommendation from my teen). The company is envisioning a world where anyone can create apps for fun, not just for a purpose, as with other vibe coding app platforms for micro apps, like Anything, and others.

Despite being relatively new, Gizmo’s feed isn’t repetitive. It’s filled with creative mini apps, leading to an experience that feels somewhat like a mash-up between TikTok and the interactive 3D space designer, Rooms. But while Rooms introduced the programming language Lua to those who wanted more advanced controls over their creations, Gizmo keeps things prompt-based and simple.

The app is incredibly easy to use. You simply type out your prompt and then see how it turns out, and then modify as needed. In one test, the AI quickly coded a mini quiz, but we had to instruct it to edit the title, which was cut off at the top of the screen.

The resulting creation can be shared to the app’s feed, messaged to a friend, or posted to social media using a unique URL.

According to data from market intelligence firm Appfigures, Gizmo has roughly 600,000 installs, with around half coming from the U.S., after being introduced with little fanfare less than six months ago. Around 235,000 of its downloads came in December alone, representing 39% of its total count.

Gizmo’s growth from October to December was 312%, with December installs up 50% month-over-month and November installs up 180% from October.

The app is available on both iOS and Android.
