The AI Campaign Companion for Game Masters

Your campaign, remembered.

You run the table. Realmweaver keeps the canon — recaps written for your players and published to a page they can bookmark, a world bible that catches your contradictions, and prep coaching from an AI that knows every NPC you've ever named.

Free forever · no credit card · your campaign stays 100% yours.

The Ember Vault — Session 12 · published to your players
Chronicle
The Salt Queen's Bargain

The party descended into the flooded vault beneath Marrow Keep, where Marshal Kade's betrayal finally surfaced — the writ he's been carrying bears the Salt Queen's seal. Vessa struck the bargain anyway: safe passage for the refugees, in exchange for the name she swore never to speak.

Where things stand
Marshal Kade
Exposed — but the party still needs him
The Salt Queen
Holds a name she can spend at any time
The refugees
Safe passage promised, not yet delivered

"After a four-hour session, nobody wants to write the recap. So nobody does — and by next week, your players have forgotten half the campaign."

The prep, the notes, the NPC voices, the threads you're holding in your head between sessions — being a GM is a second job. Realmweaver takes the paperwork half of that job.

How it fits your table

Before, after, and between sessions

Before the session

Prep with a veteran GM

Run a Game Master prep session: Quill pulls from your world — factions, NPC motivations, your main characters’ unresolved threads — and helps you plan stakes and situations, not scripts. Prep in thirty minutes what used to take an evening.

After the session

Notes in, recap out

Paste your raw, messy session notes. Chronicle turns them into a polished recap written in your world’s voice, a structured event log, and a fresh “where things stand” snapshot — and proposes updates to your world bible, which you approve one click at a time.

Between sessions

A page your players bookmark

Publish each recap to a public campaign page your players can actually read — the story so far, the confirmed events, the open threads. Never your raw notes, never your secrets. You choose what’s shared, session by session.

The world bible underneath

A campaign wiki that keeps itself honest

Every NPC, faction, location, and artifact lives in a living wiki — built through guided sessions, imports of your existing notes, or by hand. Then it starts working for you:

Consistency checking

The wiki stores discrete facts alongside prose, so Realmweaver can flag the contradictions players love to catch — the innkeeper who changed names, the war that’s dated two ways, the NPC who died twice.

Everything cross-linked

Mentions link themselves to the right entry. Relationships are typed — ruled_by, betrayed, worships — so the web of your campaign is navigable, and visible on a relationship canvas.

Point the AI at your canon

Type @ in any session to hand Quill a specific entry’s full contents — “plan tonight’s heist, and keep it consistent with @Marrow Keep.”

Your map, pinned to your lore

Upload your hand-drawn or commissioned campaign map and pin locations to their wiki entries. Click a pin, get the lore.

You approve every change

Nothing writes itself into your canon silently. Session extractions and Chronicle updates are proposed first — you accept, edit, or skip, entry by entry.

Your campaign is yours

Full export any time, in standard formats. Your content is never used to train AI models, never shared, never sold. That applies to the free plan too.

Three campaigns deep? Bring it all with you.

Import your existing campaign documents and Realmweaver reads them into structured, cross-linked wiki entries — NPCs, places, factions, events — ready for Chronicle and consistency checking from day one. No re-typing your world into templates.

Keep your table hooked between sessions.

Free to start — run your next session, paste the notes, and send your players a recap they'll actually read.
