AI features
for DMs that want them…

Semantic Search

Vellum will be using retreival augmented generation to enable deep natural language search of your Worlds, your campaigns, your sessions, your characters and your items.

Can’t remember what that tavern was called when your group punches the Dwarven bartender for no good reason?

Ask in natural language and Vellum will find the content with hyperlinks to the session notes, the tavern, the bartender and all contextual information related to your search!

AI-powered creation

Using decades of professional DM experience, and decades of research into the greatest fantasy & sci-fi authors on the planet, we have created the richest set of guided workflows for world, story / campaign and session creation found in any TTRPG software.
You can input key information, story hooks and ideas into Vellum. Fine-tuned generative AI agents that are trained to be exceptional storytelling, world-building and narrative structure assistants will then guide you to create incredibly immersive and unqiue stories and worlds.

AI-powered iteration

During sessions it’s inevitable that your Group will have gone off on random side-quests and maybe even destroyed that critical magical amulet that was key to your overarching prophecy for the entire campaign that you spent days outlining...

Yeah, we’ve been there. Many. Times.

Once you’ve uploaded your session notes, Vellum can reoptimise future sessions, and the overarching narrative, to account for any world or campaign-bending changes your group have invoked on the world.

Want to write everything end to end yourself? Turn the AI features off.
Don’t want the guided workflows and want to freestyle? Turn them off.

We want to cater to all DMs - from amateur to expert and everything in between - who need different levels of guidance and support. As such our platform offers tonnes of non-AI features and functionality that support DMs to level up their game.

The Vellum Team

Neal / Koibu
Neal has decades of professional DM experience, streaming thousands of hours of live roleplay to tens of thousands of streamers around the world. Neal is renowned for building an immersive world called Arcadia. Vellum is the DM tool Neal never had - often having to stitch together wikis, docs, spreadsheets, handwritten notes, encounter tables, dice tables and everything in between to run campaigns. Neal’s experiences shape much of the UX, workflows & features you’ll love in Vellum.

Nick / Greenzerg
Nick has years of experience playing D&D online as a player (often in Neal’s campaigns) and occassionally as a DM. Nick brings unique perspectives as a brilliant player and as a novice DM, who has often failed to get campaigns off the ground because he didn’t have the structures, frameworks, know-how or time, amidst a busy professional life, to build the campaign he’d be proud of. Vellum will change that for Nick and for many other aspiring DMs.

Chris / Crash
Chris is an obsessive fantasy and science-fiction reader and writer, ocassional TTRPGer, and a professional AI practioner, having architected scores of complex AI solutions for big enterprises around the world. Chris also has a degree in Linguistics, meaning he enjoys codifying the science and structures behind great stories. Chris brings together his love for fantasy and sci-fi, his love for narrative structures, and his expertise in AI - and pours it all into Vellum.

We care deeply about bringing a thoughtful, beautiful
and ultimately incredibly useful tool to the world of TTRPG.

Thank you for supporting us and Vellum, you won’t be disappointed.
