I cannot find this "internet novel" with any keywords like black or swarm or eyes, and I would love to read it again.

I'm pretty sure the chapters were posted on reddit, and it's the story of some kind of spaceship that appears one day, and a swarm of (black? undefined?) kill-bots are destroying humanity through the eyes of the humans somehow.

A small group of rebels find out that you must close your eyes and make no sound to stay undetected, but I don't remember how it ends.

This novel was eventually posted on its own web site, but I do remember reading it on a site like reddit. It's not a commercial project.

If anyone remembers this... Thanks!
