local-first privacy tools, embedded systems, and computation in places computation has no business being.
i build local-first privacy tools, embedded systems, and computation in places computation has no business being.
i run quantara innovations, a small lab building public-good tools with a focus on harm reduction and privacy. everything here is free and openly licensed, and stays that way.
01
language models, a diffusion model, a ray tracer and a fluid sim that run in the stylesheet. no javascript, no canvas, no webgl. just the cascade.
new · november 2026
a denoising diffusion model that runs entirely in css. it turns a random seed into noise and denoises it into a 16×16 pixel-art sprite.
@property registers<script>the sprites here are a replay drawn for this page, using two of its training sprites. the real model is behind the button.
a 78,672-parameter chat transformer running entirely in css. rope, rmsnorm, swiglu, int8 matmuls, and a kv cache made of custom properties.
a 6,796-parameter puppygirl language model that runs in pure css. no javascript, just the cascade. she mostly says things about the ball.
a real ray tracer with zero javascript. every pixel is an empty div and the css engine does all the math shadows, reflections, an animated sun.
above: a 504-div miniature written for this page. one sphere, one floor, one shadow, traced in calc().
an sph fluid simulation in pure css. the style engine integrates ~240 timesteps of weakly compressible navier–stokes down a chain of nested divs, and the scrollbar can be the time axis.
above: a doodle, not the sim. the real one solves the equations.

firmware for things with very little ram and, usually, a very small screen.
doom-style raycaster on an esp32-c3 and a 0.42-inch ssd1306 oled, controlled from your phone through a wifi captive-portal web gamepad.
audio-reactive glitch camera for the esp32-p4-eye. filters, photo and avi video, hardware jpeg, on-device gallery.
a touch weather station for the esp32 "cheap yellow display": openweathermap, custom sd-card backgrounds, and an on-screen keyboard.
hardware h.264 encoding on the esp32-p4x-eye: 1080p25 at about 34.7 ms average encode latency on rev 3.1 silicon.
app-free control of roku smart bulbs through a reverse-engineered cloud api. a cli and a local web dashboard; no app, no flashing.
03
tools that should exist, free, for the people who need them. several are quantara innovations projects.
harm reduction
a free, plain-english, state-by-state guide to getting naloxone in the us. it is a static site that installs like an app and keeps working offline.
spot meta ray-ban glasses and other nearby recording devices over bluetooth, for your privacy. a web app and an esp32 build.
reduce background clues in photos shared from home. a browser-based scrubber and guidance for getting listing photos taken down.
view, back up, rotate, and reissue the windows device id microsoft won't let you turn off
a passive, privacy-conscious observatory for how crawlers, retrieval systems and autonomous agents read a fictional documentation site.

small models trained from scratch, fine-tunes with opinions, and audio that runs on the machine in front of you.
a free, open-source real-time voice changer for windows: 20 live voices, local ai voice conversion (seed-vc on onnx runtime), soundboard, virtual mic, hotkeys.
a tiny from-scratch rectified-flow model for vintage newsprint smiley faces and text :3
a puppygirl chat model that still answers the question. v2 is a conversational roleplay fine-tune of qwen3.5-4b.
a lightweight sound-event-detection ensemble for birdclef+ 2026: pantanal wildlife acoustics, cpu-only, inside a 90-minute inference budget.
an eval kit for small-model software-engineering agents on the gemma 4 developer agent harness: a fixed grader, a miner, and a calibrated gate.
05
small, silly, or both.
