A local visual markdown vault for worldbuilding, story bibles, game notes, TTRPG campaigns, and idea maps.

Seagraph is a writing tool built around a living graph. Make nodes for characters, places, timelines, factions, systems, scenes, research, or whatever your project needs. Each named node becomes a plain markdown note, so your work stays local, readable, and easy to back up.

Build a World You Can Actually Navigate Seagraph is for projects that get too big for one document and too personal for a generic productivity app. Use it to map: - Fiction worlds and story bibles - TTRPG campaigns and setting lore - Game design notes, quests, characters, and systems - Research webs and personal knowledge maps - Moodboards with images, animations, and music - AI-assisted writing workflows where you remain the canon source The graph is not the writing. The graph is how you keep the writing alive long enough to find it again.

Plain Files, Local First Your vaults are ordinary folders next to the app. ```text Your_Project_vault_/ notes/ markdown notes graphs/ visual layouts media/ images, animations, and audio

No account. No cloud lock-in. No database you have to trust with your entire fictional universe.

Back up a project by copying its vault folder.

Notes, Maps, Media, and Wikilinks

Each named node can have its own note. Notes support simple markdown, headings, bullets, quotes, and wikilinks like:

[[World]] [[the old city||Old City]]

Attach images, animated GIFs, APNGs, WEBPs, and music to notes. Use nested maps when a single idea deserves its own room.

Built for Writers Who Use AI Carefully

Seagraph includes send-me-to-llm.txt, a helper file you can give to Codex, Claude Desktop, or another local assistant when you want help inspecting or organizing a vault.

The idea is simple: your vault stays as plain local files, and the assistant gets rules for how to edit them safely.

Good for:

• Auditing broken links
• Turning source notes into clean markdown
• Planning a world bible structure
• Expanding notes without losing track of canon
• Reviewing graph files without casually wrecking them

The human remains canon. The machine does the shoveling.

What You Get

The download includes:

seagraph.exe README.md send-me-to-llm.txt secret-bonus-program

Optional releases may include an example vault so you can open Seagraph and immediately see how a project can be structured (it's not that complicated tho).

Seagraph is self-contained and runs locally on Windows. No installer required. The file itself is only 2,620 kilobytes. Compare that to Obsidian's 250-800 megabytes. Talk about saving the planet! (am-i-right?)

First Launch

Unzip the download, put seagraph.exe in its own folder, and run it.

To make your first vault:

1. Press SHIFT+A.
2. Hover the new node and press TAB.
3. Type a vault name.
4. Press ENTER.
5. Double-click the vault, or hover it and press ENTER, to go inside.

Press F11 or P for fullscreen. Very official. Very dramatic.

Good For

• Writers with messy lore
• GMs with sprawling campaigns
• Indie devs building worlds and systems
• Visual thinkers who still want plain markdown
• People who like local files more than mysterious cloud magic

Platform

Windows.

Seagraph is currently a local desktop tool. Your vaults live beside the executable, so keeping the app in its own folder is recommended.
