Spell

Programs you can read out loud.

a "card" is a view:- its "suit" is one of clubs, diamonds, hearts or spades- its "color" is:red if its suit is diamonds or heartsblack otherwise- its "rank" is one of ace, 2 ... 10, jack, queen, king- it "is a face card" if its rank is jack, queen or king

You just read a program.
Nobody taught you its syntax, and you could explain it to a friend.

It isn't pseudo-code, and it isn't an AI prompt:

a rule-based parser reads Spell the same way every time, and
it compiles to optimized, readable code you can run right on the web.

Solitaire in Spell

Solitaire in Spell – animated with drag-and-drop – in less than 400 lines of code.

¡El mismo juego, en español!

The same game — code and interface in Spanish – with automatic translation.

All magic, no fuss!

A language that reads like English (and Spanish, soon French, German...)
– types, properties and actions are sentences.
A compiler to JavaScript, TypeScript and Python
– so what you write runs where you need it.
An editor where the program, the running app and its output sit side by side.
