Run unforgettable sessions every week.The one night your table doesn't miss.
A Campaign Assistant that's read every note you've written and every rulebook you've taught it. The callback from session 12 is there when it matters. The rule's in front of you when you need it. The story you've been building shows up at the table intact.

GMing shouldn't feel like a second job.
Tools built around how real game masters work. They read your notes, cite your rulebooks, and wait for your approval before anything saves.
The Collaborator
A campaign partner that knows your campaign
ChatGPT doesn't know who your villain is. ScriptoriumGM does, because it reads your notes, cites your rulebooks, and drafts new material that fits the world you've been building.
- Reads your notes
- Cites your rulebooks
- Drafts new notes
- Rolls dice
- Generates images
In-Note Review
AI edits your notes, you approve every change
When the assistant proposes an edit, you see it previewed inside the note itself, with each changed section outlined in gold. Step through every change, accept what works, reject what doesn't. Nothing saves until you say so.
- Gold-outlined change markers
- Jump section by section
- One-click accept or reject
- Nothing overwrites without you
- Resumable across tabs
The Library
Your notes, your rulebooks, one searchable home
Every campaign gets its own walled library: folders, typed icons, wiki-style backlinks, searchable. Upload rulebooks and choose which ones the assistant is allowed to read from.
- Folders & typed icons
- Backlinks everywhere
- PDFs, DOCX, Markdown
- Per-campaign walls
- Teach it what to read
More Power Tools
Built for how GMs really work
Bring Your Obsidian Vault
Zip your vault, drop it in. Wikilinks become references, embedded images upload, your folder layout is preserved. Years of prep come with you.
Pick Your AI Model
Fast for a quick rules lookup, Powerful for an evening of deep worldbuilding. Pick per conversation, so you decide where your budget goes.
Any TTRPG, Even the Weird Indie One
D&D, Pathfinder, Call of Cthulhu, Blades in the Dark, and more ship with system-aware configs. Running something else? Upload the rulebook and teach it.

Watch how ScriptoriumGM helps game masters prepare and run better sessions.
Stop adapting to your tools. Make them adapt to you.
Whether you're running the latest D&D adventure or the homebrew system you've been tinkering with for years, ScriptoriumGM adapts to your game instead of asking you to adapt to it.

Frequently asked questions
Quick answers to the things people ask most. Think of it as the scribbled notes in the margins.
Is ScriptoriumGM really free?
Yes. The free tier ships the full product on the Fast model: library, editor, Campaign Assistant, image generation, every supported system. You can use it indefinitely without paying.
What's the waitlist for?
We're onboarding users in batches to keep the experience good for everyone already inside. You'll get full free-tier access when it's your turn. No payment required.
Do I need to support on Patreon?
No. Patreon is optional. It unlocks the Balanced and Powerful models and a larger monthly budget for GMs running longer campaigns or heavier prep sessions. The free tier is a real product, not a trial.
What systems does it support?
D&D, Pathfinder, Call of Cthulhu, Blades in the Dark, and many more have dedicated configurations. Running something else? Upload your rulebook and teach it directly.
How long is the wait?
Wait times vary as we onboard users in batches. You'll receive an email notification the moment your account is activated.
Can I bring my existing notes?
Yes. Zip your Obsidian vault and drop it into the importer. Wikilinks become references, embedded images upload, folders preserved. Markdown and Google Docs imports also supported.
