Two-Player TTRPGs Built for Real Campaigns
Down to two players and want more than a one-night stopgap? These are the duet TTRPGs built to actually carry a campaign, and why they hold up.
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. Ask who your players swore that oath to back in session 12 and the answer comes back with the note it came from. No scrolling.
No credit card · Full product on the free tier · Community open on Discord
GMing shouldn't feel like a second job.
Nothing writes to your campaign without your say-so. Every new note, every edit, every portrait the Campaign Assistant proposes waits for you to accept it.
The Collaborator
A partner that already knows your world
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
Build a campaign wiki as you take notes
Link notes as you write. Each one becomes a badge you can tap to jump to, or hover to preview without leaving the page. Every link records both ways, so a character or faction carries a running list of everywhere it's come up. A player asks who that merchant was? Two taps.
- Tap to jump, hover to preview
- Backlinks on every note
- Folders & full-text search
- Per-campaign walls
- PDFs, DOCX, Markdown
- 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.
A Demonstration
See the assistant at work
Watch how ScriptoriumGM helps game masters prepare and run better sessions.
Stop adapting to your tools. Make them adapt to you.
Ask for encounter ideas in Blades in the Dark and you won't get a D&D encounter table. Pick your system when you create the campaign, or upload the rulebook for the homebrew you've been tinkering with for years.

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. We'll email you the moment your account flips to active.
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.

Why Your AI Doesn't Know Your Campaign (And the Fix)
Your AI just confidently invented a promise an NPC never made. Here's why chat-window AI forgets your world, and the one principle that actually fixes it.
The Invitation
Less prep. More table time.
Bring your notes, your rulebooks, and the campaign you've been running for years. Get back to the part you actually signed up for: sitting at the table, rolling the dice.
