Profile

I built vid2ascii - a browser app that turns video into ASCII art in real time using WebGPU.This started as a super rough v0 I hacked together on my commute, literally on my phone, just from a simple prompt. It worked, but it was janky and CPU-bound like most video-to-ASCII demos. I kept thinking about it, came back later, and polished it properly.The big change was moving the core work onto the GPU. Instead of slow canvas pixel loops or WebGL hacks, vid2ascii uses WebGPU compute to process each frame at full resolution. That’s what makes smooth playback and high-fidelity ASCII actually possible in the browser.Live demo: https://wspr-zeta.vercel.app/Code: https://github.com/Luthiraa/vid2asci

As a business in show hn launch, Vid2ascii – real-time video to ASCII with WebGPU is listed here with the public details available about it.

It is recorded at the Show HN launch stage.
