I make little apps for things that annoy me. Mostly for the fun of making something useful.

A hobby, not a grand plan.
Some things I’ve made. Have a play.

Tidies the layout of messy notes. Keeps your words.

Little demos, not the live apps. The note is a fixed sample; no AI requests.

As Written

Tidies the layout of messy notes. Keeps your words.

Why this exists

An idea can come out as one long block of text. Asking an AI assistant to tidy it can turn into extra context, extra features, or words that don’t sound like you. I wanted the writing to stay yours — just easier to read.

As Written organises the text you give it without adding ideas. Optional spelling, punctuation and capitalisation corrections are separate from layout-only formatting.

Colorsum

A visual place to explore colours and put together kits.

Why this exists

I wanted a visual space for working with colours and bringing them together in kits. Colorsum started with that idea.

Explore the colour canvas and put together colour kits in the app. The little colour study here is just something to play with — it doesn’t generate or save a kit.

Small things are worth making.

These started with little frustrations: a note that was hard to read, colours that needed a place to come together. I like making something useful out of those moments.
