Humane Ai Pin hacks turn the discontinued gadget into a standalone Android-powered gadget

The Humane Ai Pin is a tiny wearable device that launched in 2024 and was discontinued less than a year later. With a microphone for voice input, a built-in camera, and a projector that displays information on your hand, it was designed as an AI companion device. And when it was canceled, it basically stopped working.

But independent developers stepped in and started looking for ways to keep the hardware functional. And now, more than a year after official support ended, the Ai Pin is actually more useful than ever.

A open source project called PenumbraOS leverages a vulnerability in the Android operating system that powers the Ai Pin to let you jailbreak the device so you can keep using it without connecting to Humane’s servers (which shut down in February, 2025).

In order to jailbreak an Ai Pin, you do need some custom hardware (you can either build your own interposer or buy one). Once you’ve got that, you can use the web-based PenumbraOS Center to install the software and/or control devices connected to your home network.

Among other things, the software lets you use the Ai Pin with third-party AI service providers OpenAI, Anthropic, or Gemini. But you can also set it up so that it’s basically a wearable Android device that either uses the original software interface or a custom launcher.

The Ai Pin’s spec include a Qualcomm Snapdragon 720G processor (with two Cortex-A76 CPU cores, six Cortex-A55 cores and Adreno 618 graphics) 4GB of LPDDR4X RAM, 32GB of eMMC storage, a 13MP camera and depth sensor, a 720p green MEMS laser projector, and support for WiFi 5, Bluetooth 5.1 and 4G LTE and GPS.

PenumbraOS was recently updated with “a newly weaponized exploit” that “is able to tap directly into the apps and system software that they built for the Ai Pin” so that you “can use the ORIGINAL on device cosmOS experience, but entirely local, entirely private. It’s still designed primarily for voice interaction though.

Another project called FusionOS brings a custom visual interface to the projected display, with support for features including time, date, temperature, notification count and previews, battery percentage, and phone calls. You can also launch apps and manage text messages or tap an Ai Pin running FusionOS to interact with Google Gemini or other AI assistant software.

Developer @AndersDoesTech is also working on mobile companion apps for iOS and Android that let you sync your contacts to a pin, view battery and storage information, transfer photos to your phone, and configure WiFi, eSIM, and OpenClaw settings, among other things.
