About

Computer Science graduate from the Vrije Universiteit. I wrote my first program in 2013, and I have been building with language models since the GPT‑3 API, well before ChatGPT made them a household name. I learn fastest when I am dropped into something unfamiliar. I am curious and talkative, and happy to jump into whatever comes next. I like debugging, and I like the part afterwards where a thing slowly stops being annoying to use.

Read by Mimic, not by me. It learned my voice from one paragraph, on my own laptop.

Selected work

Mostly things that run on your own machine.

Mimic

Type something. Hear it in your own voice.

Read one paragraph aloud, and it will say anything you type in your own voice. A web app, a Mac app, and an iPhone app that does the whole thing on the phone, with no network at all.

Every word of this was spoken by a model running on my own laptop, in a voice it learned from fifteen seconds of me reading a paragraph aloud.
