Cheese Paper: An offline, file-based text editor built for writing fiction

Cheese Paper is a GPLv3-licensed writing tool aimed at fiction authors who want their drafts and notes to live as plain files rather than inside a proprietary database. Each scene is stored as a Markdown file with a TOML header for summaries and metadata, so projects remain editable in any text editor and survive external changes made while the app is running. Character sheets, worldbuilding notes, and scene summaries sit alongside the prose, and the whole project can be exported as a single Markdown file for conversion via Pandoc to EPUB, DOCX, or HTML.

The tool deliberately positions itself against subscription-based writing services. It runs entirely offline, makes a single network request for update checks, and leaves syncing to the user via Syncthing, Nextcloud, or similar tools. The author frames it as a narrower alternative to Scrivener, Manuskript, and Obsidian, with localization support and a randomized-theme novelty button. Releases are distributed through Codeberg with installers for Windows and macOS.
