PalUI

Agentic launcher for microcontrollers.

We aim PalUI to be a combination of a launcher for your programs for microcontrollers + a chat interface, combined together to make a simple, easy-to-use launcher for microcontrollers. We plan to develop our edge AI models like Espic2 further to make PalUI agentic.

Switch between your own local models when you're offline or tap into cloud APIs like Gemini when you need more power.

Soon, you'll be able to install apps built by the community like games, tools, apps, whatever you dream up. PalUI is basically going to be a chat-focused agentic launcher for microcontrollers.

You can flash PalUI right now using PalUI Online Flasher. No need to compile yourself.
