WUFFI / WINDOWS MARKDOWN EDITOR
A minimal interface, built for writing.
Discuss your writing with AI right in the editor,
or ask it to revise a passage, without copying and pasting.

WHY WUFFI
Markdown editors are already mature. But the tools that feel good enough to use for years are often paid, or keep growing more complex.
Obsidian is powerful, but it feels more like a personal knowledge base and note-taking system than an editor built simply for writing.
I wanted to build a product with an extremely simple interface, made for writing. No complicated features or interface: just a clean, uncluttered experience that helps you focus on the text.
Writing is rewarding in itself, and people write for different reasons: blog posts, video scripts, business plans, journals, or simply to record everyday life. Creative work does not always have a direct financial return, but writing still calls for some productivity. Minimalism alone, without thinking about productivity, can fall out of step with the way we work.
That is why I also wanted to bring an AI agent into this minimal interface. You can discuss how to write something or ask for revisions right inside the editor, without copying and pasting. The aim is a smoother, more efficient writing process.
Wuffi is for people who enjoy the act of writing, welcome tools that help them work, and still want to keep their words their own.

Normal editing and draft recovery happen locally. When you use AI, the selected document content and conversation history are sent to the model service you configured. For a local model, make sure the endpoint points to your own computer. AI requests are not sent automatically as you type.
The editor does not install or start an AI model. You need to set up a compatible model service separately.See the setup steps。
