Sky High Infinite Techwork presents

Draft the story. Own the vault.

Mythos Writer is a local-first desktop studio for fiction — Word-like writing, Obsidian-compatible vaults, and Liquid Neon glass. One writing partner you can chat or call with — on your keys, local, or with AI off so you write by hand.

The app, as designed

A full-window desktop studio — not a browser tab. This capture is a Liquid Neon design mockup. The interactive preview explores upcoming chrome and is labeled as such.

Mythos Writer manuscript — chapter heading and scene prose in the Liquid Neon editor

Writing

A scene editor that stays out of the way

Draft in a Word-like scene, then keep the book as Markdown you can move, diff, and keep. Structure, Editor, and Book are three views of the same manuscript.

Structure · Editor · Book

Cards, the page, and a compiled read — one manuscript, three desks.

Wiki links

Type a name as a [[wiki-link]] and it stays live in the vault.

Notes Properties

Tags, fields, and backlinks sit on the note — not in a separate database.

Boards

Kanban-style cards when the outline needs to move.

Scene Crafter

Shape a scene — POV, goal, conflict, beats — then write the prose yourself.

Export

EPUB and DOCX when the draft is ready to leave the vault.

World

A bible that lives beside the book

A Mythos Vault is one world. Story Vaults hold the manuscript; Notes Vaults hold lore. Open an Obsidian vault in place — it stays a folder you own.

One world on disk: Story Vaults plus Notes Vaults, plain Markdown.

Open Obsidian in place

Keep an existing vault where it is. Mythos adds a Story Vault beside it.

WikiLink graph

See how names connect across notes and scenes.

Timeline

Multi-calendar, nested-world math is in the product. The desk UX is still being polished.

Partner

One writing partner

Chat or talk with one in-app partner about your book. Past chats and calls live in one place. You set the name and icon.

Not four separate bots. One partner — text and voice in the same thread.

Call

Talk it through

Start a voice call with your writing partner. Spoken and typed turns share one chat thread. End the call and keep the same conversation as text.

Call chrome on the chat. One stream — no separate call transcript to lose.

Keys

Your keys. Or none.

Bring your own API key, run a local model, buy Mythos AI credits later, or turn All AI off and write by hand.

Core writing never needs AI or an account.

Local-first

Write without an account

Mythos Writer is a desktop app. Your vault stays on your computer as a folder you own. An account is only for purchase and license proof — not for writing.

Yours on disk

Core writing does not need an account. The vault is a folder. When you buy, sign in to prove ownership.

Liquid Neon

Frosted glass, theme slots, and a living frame around the desk.

10 themes, token-swapped

Pick a mood. The whole desk follows.

Every theme drives the same six roles — left panel, wiki-links, agents, warm data, cool data, window frame — so one palette change ripples through borders, glows, chips, graph nodes, and the frame. This page uses the same tokens.

Active theme: Neon Classic

Mythos Vault per world

“Your words should live in open, portable formats. Your vault is yours — no one mines your creative process. Your AI co-pilot amplifies your vision; it never replaces it.”
