WHAT IS IT?
========================================
Diffuji is an instant camera built at
TreeHacks 2026. A raspberry pi zero 2w
with a camera and thermal receipt
printer lives inside a custom housing.
Our project won both the Neo Prize and
Most Creative Prize! Devpost here.
Snap a photo, pick a mode, and the
image gets sent to an AI backend that
transforms it, then prints the result
on receipt paper.
Below are a few examples of some of the
different modes:
mode: greek
mode: studio ghibli
mode: muscle
mode: duck
========================================
MODES
========================================
FILTER MODES use diffusion models to
restyle your photos:
* studio ghibli style
* time-travel to past decades
* turn everyone into ducks
* give everyone swole muscles
* put Sam Altman in the photo
* and many more...
SEARCH MODES use perplexity web search
to analyze what the camera sees:
* estimate price of visible items
* identify objects and landmarks
Each request is routed to one of four
AI providers so you can A/B test the
same prompt across different backends:
[1] OpenAI (gpt image 1.5)
[2] Gemini (2.5 flash image)
[3] Modal (flux kontext on h100)
[4] Perplexity (sonar pro web search)
