Key Features

WYSIWYG Editor

In Compositor, as in other WYSIWYG word processors, you edit the rendered document itself, and updates appear instantly with every keystroke.

Smart Source Editor

A modern source editor with syntax highlighting and smart completion suggestions is available when you need fine control over the document source.

Graphical Formula Editor

Compositor comes with a built-in graphical formula editor, that easily lets you build up formulas from a number of building blocks.

LaTeX Distro Included

The app comes with its own basic LaTeX distribution (based on TeXLive) built right in. No need to install any additional software to get going.

Automatic Package Download

Any packages referenced by your documents that aren’t available locally are automatically downloaded from CTAN, no manual intervention required.

Native, Fast & Modern

Compositor is built for quick startup, maximum performance, and memory efficiency. The app is also sandboxed, requiring only minimal privileges.

Compatible with your Work

Compositor reads and writes plain text .tex files. This means it’s compatible with your existing documents, and there’s no vendor lock-in of any kind.

Your Data stays Local

Your documents are stored locally and fully under your control. A tip: Put your files under git version control!

LaTeX without Entry Barriers

Compositor comes with everything to get you started writing beautiful LaTeX documents. Give it a try!

“My goal with Compositor is to offer the most beginner-friendly LaTeX user experience.”

About the macOS Free Trial

The app is currently a free download with no restrictions of any kind. And I won’t charge anything for the app until it reaches a truly usable state — which I roughly define as “a student can write a master’s thesis with Compositor”. I have also written a blog post about this.

All I’m asking for at this stage is to spread the word, try it out, and send me feedback if something isnt’t working.

About the Windows Alpha Version

The Windows version is currently at a prototype stage, but will eventually catch up with the Mac version. My goal is to keep the two versions at feature parity from that point on.

Both the Mac and Windows versions are built on top of the same shared core code. The only thing that’s different between the two is the UI layer, really. This approach is what makes supporting both platforms feasible for me as a solo developer.
