Start with the piece that matters tonight
Run the campaign
Sessions, NPCs, quests, maps, relationships, timelines, and share pages stay connected.
Follow one character
Create beyond the sheet with writings, relationships, play journal notes, and share-safe pages.
Bring your character in
Upload the sheet, document, image, or notes you already have. Multiloop turns the scattered material into an organised character draft ready for review.
Review what changed
Campaign Analysis and Character Analysis propose updates; you approve what belongs.
Multiloop Complements Your Tools
It doesn't replace your VTT or character builder. Start simple, and let Multiloop keep your story, session history, and collaboration connected.
Multiloop is the story layer. Start with notes, characters, and session prep. Add maps, Guide pages, World references, quests, and deeper collaboration when you need them.
Three Ways Multiloop Connects Campaigns
Multiloop isn't just another campaign tracker. These are the features that make your games genuinely better.
Your World Evolves From Your Sessions
Write session notes naturally. Analysis reads everything and suggests updates to your NPCs, quests, lore, and timeline. You review and approve. Done.
- Write notes naturally. Analysis does the bookkeeping

Characters Beyond The Sheet

- Start with one character before you make a campaign
- Paste a Google Doc or upload a sheet into a reviewed vault draft
- Link the same character into campaigns when the table is ready
- Character Analysis proposes reviewable updates from supported context

Common Questions
Everything you need to know before you sign up.
Is this a VTT?
No. Multiloop is the story layer for your campaign, not a virtual tabletop. It complements Roll20, Foundry, and any other VTT you use. Use your VTT for battlemaps and dice. Use Multiloop for everything the story needs.
Does it replace D&D Beyond?
No. D&D Beyond handles official D&D rules, character sheets, spells, and mechanics. Multiloop handles campaign narrative: backstories, session history, world details, and the stories that make your game memorable.
What game systems does it support?
Multiloop is narrative-first and system-agnostic: no stat blocks, no rules lookups. It works as a story and memory layer alongside 5th Edition, Pathfinder, Call of Cthulhu, Blades in the Dark, Mothership, and other systems you bring to the table.
Can I use Multiloop just for my character?
Yes. You can start with a standalone Character Vault record, keep writings and play journal notes, share safe sections, and link the character into a campaign later.
Do session notes change character records by themselves?
No. Character Analysis can propose updates from supported character context, relationships, writings, play journal notes, and linked campaign context when available. You review suggestions before anything saves.
Is my data private?
Yes. Your campaigns, characters, and notes are private by default. You choose when to create share links, what those links expose, and when to revoke them.
Can I import my existing notes and characters?
Yes. Paste from a Google Doc or upload supported files such as PDF, DOCX, TXT, Markdown, PNG, JPEG, or WebP. Multiloop prepares a character draft for review, then you choose what saves to your vault.
Can multiple players join one campaign?
Absolutely. Invite players, assign roles (DM, co-DM, Campaign Editor, player, guest), and control exactly what each person can see and edit. Co-DMs can help run sessions, Campaign Editors can manage content without member-admin or live-session controls, and players bring their own vault characters while DMs keep secrets safe behind visibility controls.
Is Multiloop free to start?
Yes. Create a free Multiloop account and run a real campaign with core campaign and character workflows. There is no trial timer.
Can I export my data?
Yes. Settings includes a machine-readable JSON export of core account data, including campaigns, characters, sessions, timeline events, vault characters, one-shots, tags, and selected settings metadata.
