COUNSEL THE CODEX ATMOSPHERE HOW IT WORKS JOIN THE BETA
LISTENING AT THE TABLE

A tome that listens while you run the game

Grimoire hears your table, transcribes every word, and whispers counsel drawn from your own campaign — rules, story threads, NPC voices — the moment you need it.

NPC
Verrick recognizes the sigil on Kira's dagger — he owed her father a debt he never repaid.
Raspy, over-friendly, glancing at the door. He offers 50 gold far too quickly.
Ask the tome — “what should they find on the body?” ASK
TRANSCRIPT
DMVerrick leans over the counter…
KIRAI show him the dagger, hilt first.
WHO?Wait, can I roll insight on him?
DMSure — everyone else, hold on.
WHAT THE TOME DOES
🕯
Unbidden counsel
As the table talks, the tome offers what matters now: the rule being argued, the arc this moment touches, how the NPC would answer. Pin what you'll use; dismiss the rest.
RULES STORY NPC IMPROV
Ask anything, mid-scene
“What should they find on the body?” “Range on fireball?” “Name this NPC.” The tome answers from your campaign and the rules — grounded in what was just said aloud.
It knows Verrick owed her father a debt, because you wrote it.

A faithful transcript
Every word at the table, scribed live. Unrecognized voices are flagged — tap to assign the speaker. After the session, it becomes recaps your players actually read.

THE CAMPAIGN CODEX

Your whole campaign, a ribbon-pull away

The Codex binds your players, NPCs, arcs, and relics — read straight from the markdown files you already keep. During a fight, the Order of Battle tracks initiative, HP, and conditions, auto-scribing damage it overhears (with an undo, because tables argue).

And when you need something from three sessions ago, summon THE INDEX — press ⌘K and search every transcript, recap, and note in the archive.

THE ATMOSPHERE

It scores the scene while you speak it

Grimoire listens for the shape of the moment — a negotiation souring, steel drawn, a cellar flooding upward — and shifts the music to match. It tells you why it chose the track; skip it and it learns your taste.

Point a second screen at the table and it keeps an ambient image or slow-moving video of wherever the party stands, changing as the story moves — no fiddling with a soundboard between lines of dialogue.

HOW THE MAGIC WORKS
I
A MIC ON THE TABLE
One microphone hears the room. Speech becomes a live transcript, speaker by speaker — pause it any time the table goes off the record.
II
YOUR CAMPAIGN AS CONTEXT
Players, NPCs, quests, locations, past sessions — plain markdown files in a folder you own. No lock-in; edit them with anything.
III
CLAUDE, AT YOUR SHOULDER
Claude reads the transcript against your campaign and offers counsel in the moment — then preps sessions, plans battles, and writes recaps between games.

Run the game. The tome keeps the book.

The beta is small — a handful of tables, a mic each, and campaigns full of people who talk over each other. Leave your name in the ledger.

No spam — one letter when your invitation is ready.
