Gate guard. Burn scar on left hand, competent with a crossbow.

Run the session. Keep the campaign.
Arcane Atlas listens to your session and turns it into a real campaign record — NPCs, places, facts, threads, all linked. It proposes. You decide. Nothing enters your canon on its own.
Free tier, no card. Your players never need an account.

Your Atlas
Nothing yet. Approve something on the left and it lands here — entity pages, linked and searchable, with the line of transcript it came from still attached.
This is the real flow, running here on the page. Approve or reject and watch what changes.
Your canon is not editable by a model
Every AI output and every player submission arrives as a proposal in a review queue. Approve, edit, or throw it out. The campaign only changes when a person changes it — and every entry keeps the transcript line it came from.
Prep is a workflow, not a blank page
Open threads, unanswered player questions, clues nobody found, clocks about to fill, hooks your table voted on. The prep brief is assembled from what actually happened last session, not from a template you have to fill in.
One place per player, per fact
Visibility is per field and per audience, so the same NPC page shows your notes to you and only what the party has learned to them. Preview any page exactly as one character sees it before you share it.
Built for a table that meets
Arcane Atlas is a GM tool for campaigns that are actually being run: sessions get closed out, players ask questions between games, and the world accumulates. It handles fixed rosters, open tables, and West Marches style play through campaign settings rather than separate products.
It works with Discord for player-facing posts, imports what you already wrote in Obsidian or a doc, and exports everything back out whenever you want. Leaving is not punished.
What it is not
- Not a virtual tabletop. No maps with tokens, no dice roller for combat. Bring Foundry or Roll20 if you want one.
- Not a wiki-first tool. If what you want is the most beautiful world encyclopedia, the competition is genuinely better at that. This is built for the weekly loop of running a game.
- Not something your players have to join. They use Discord and a share link. No accounts, no seats, no per-player price.
Start with one session
Import what you already have, run your next game, and see what comes back. The free tier keeps working whether or not you ever turn AI on.
