A word from me
Words from the author
I built this editor first of all for my own use, to bring together in one place several things I like using when I work on a project or on my notes (I sync my notes with a git repo and write them in Markdown). It’s also a way for me to try out working with AI and see what it does well and where it falls short.
I use and test it on Linux (Ubuntu), but there’s a Windows guide so you can try compiling it on Windows. If enough of you do, I might think about something more lasting. For now it isn’t worth it if I end up being the only one using it.
It’s built on a fairly “classic” Rust tech stack.
If you give it a try, I’d love to hear what you think!

A look inside
Every tool has a window of its own.
Tables, formulae, whiteboards and logs are edited where they make sense — and written back to plain text.
On purpose
Small, fast, and yours.
Measured, not promised
Every feature ships with a performance budget it is tested against.
Nothing leaves your machine
No account, no telemetry, no network request the editor makes for you.
Plain files
Markdown, .canvas, todo.md, TOML: everything readable in any other tool.
No terminal, no debugger, no plugins
A deliberate limit. It is what keeps the editor small and quick.
Ten minutes to feel at home.
