MythScribe

Write your novel on your own machine.

MythScribe is a desktop app for fiction writers: a Scrivener-style organizer, a distraction-free editor, story tags, and AI that reads your manuscript and keeps your voice. It is free, it works offline, and nothing leaves your computer unless you turn the AI dial up yourself.

What it looks like

Screenshots from the current development build with a sample project. The interface is dark by default; themes come later.

The MythScribe window. On the left, a manuscript tree with Front Matter, Manuscript, and End Matter, expanded to Part One: Tides, chapter The Harbour, and the selected scene Low Water. On the right, the scene's tags (ilse, prophecy, the-ferryman, the-harbour), its location, point of view, and timeline fields, and the scene text in a serif book column.
Parts, chapters, and scenes on the left; the scene's tags, location, point of view, and timeline above the text; the editor in a book-width column.
The Tags tab in the sidebar: category filters (Characters, Settings, World Building, Tone, Content, Plot Threads, Custom), a Standard Fiction template ready to load, a search box, and a colour-coded list of tags such as ally, battle, coming-of-age, and dark-fantasy with their use counts.
A tag bank per project, filtered by category, with templates for standard fiction, mystery, fantasy, and sci-fi to start from. Type # in the editor to tag inline.
The Settings dialog on the AI tab. The AI dial shows four levels: Off, Ask, Suggest (selected), and Draft. Below it, a checkbox per feature, the ghost text idle delay, and a table listing each feature, what it sends, the provider, and the level it needs.
The AI dial in Settings: four levels, a toggle per feature, and a table of exactly what each feature sends and the level it needs.

AI on your terms

AI features are optional and off when you install. The dial in Settings runs from Off, where nothing leaves your machine, to Draft. Every feature lists what it sends, and every result is a proposal you have to accept. The AI dial page has the full table.

Bring your own key Free

Enter your OpenAI API key in Settings. The key is stored in your operating system's secure storage, and requests go straight from the app to OpenAI: nothing passes through us, and we never see your key or your text. You pay OpenAI for what you use; the app shows the cost of every request and a running total, and you can set a daily cap.

MythScribe Cloud Not yet available

A subscription for writers who would rather not manage an API key: sign in, and the app sends AI requests through a small proxy that meters usage and hands them to the provider. The proxy will not store or log manuscript text, and billing will go through Lemon Squeezy. It is not built yet; the app you can download today is bring-your-own-key only.
