The RFab Device Is Finally Ready
Pick one up for ~$45, flash it from this page, and you're done. We take nothing — no fees, no markup, no subscriptions.
Create a tutor for your kids, a cooking companion, or a portable adventure partner. We flash the firmware automatically from the browser.
What Can It Do?
Draw Art For You
Your companion can generate and display images right on the device screen.
Send Videos
Receive generated video content directly on your portable companion.
Change Expressions
Your companion shows emotions on screen — happy, thinking, surprised, and more.
See What You See
Point the camera at anything and ask about it — bugs, plants, homework, recipes.
Award Points
Gamify learning — your companion gives points for achievements and milestones.
Voice Conversation
Full voice in and out. Talk naturally and hear your companion respond.
Built For Real Life
Kitchen Companion
Slap it on your fridge with the magnets on its back. Have a partner while you cook dinner — it can read recipes, set timers, or just chat.
Kids' Tutor
We built it primarily as a tutor for our own kids. They can walk around outside showing it bugs or plants they find interesting and ask questions. If you're using it for this, we recommend locking your site in SFW mode.
Portable Adventure Partner
Take your interactive story on the go. Voice-driven quests, mysteries, and worlds — anywhere you are.
Coming Next
These device features are currently in development:

Full life-like movement and animation for your companion's avatar on the device display.
Email Integration
Your device companion will be able to reach out to you via email when you're away.
Passive Monitoring
Build devices that can passively monitor everything your kid hears throughout the day for content you don't want them exposed to.
