# pluma > Multi-canvas authoring — a *bundle of bodies* over one material — plus a reactive notebook, on [Llimphi](https://github.com/tawasuyu/llimphi). `pluma` (Spanish: *feather/pen*) is a writing tool where a document is a **bundle of `Cuerpo`s** (canvases: language, tone, audience, summary, version) over the same material, aligned paragraph-by-paragraph. Transformations (translate / tone / summarize / rewrite / custom-Rhai) derive a child body from a mother; if the mother changes, the child goes stale and the UI offers to regenerate. It also ships a **reactive notebook**: a DAG of cells run in topological order with swappable kernels (LLM, dominium, cosmos, python, wasm).
