VS Code
The same engine,pointed at prose.
Ritemark is built on VS Code OSS. The difference is everything above it: a visual editor instead of a text buffer, and a sidebar built for writing.
If you write code, keep VS Code. This is for people whose deliverable is a document.
Formatting you can see.
No split pane and no preview window. What you see while writing is what the document is.
The agents are in the sidebar.
Claude Code, Codex and OpenCode without a terminal, and a terminal too if you want one.

Ritemark
A visual editor, comments, recordings and exports, for documents.
Both
The same foundation, so the keyboard and the file tree feel familiar.
