About Koi

Work on Koi (then Hackerman Text) started in 2023, after taking a closer look at the new generation of AI code editors and deciding I wanted to build my own editor on a different foundation than VS Code and Monaco.

I was primarily a Sublime Text user at the time, so the original idea was simple: a fast text editor with built-in code completion.

Since then, Koi has evolved around what I care about most in an editor: low latency, performance, customization, and staying out of the way.
