A memory for your D&D table

Every session remembered.
Only what your character knows.

Hearth lives in your Discord. It listens to the table, keeps the whole campaign in one living memory, and answers each player from behind their own fog of war.

No new account — the same Discord your table already uses.

/ask who sold us the map to the Sunken Vault?

Hearth APPToday at 9:41 PM

Marrow Quill, the one-eyed cartographer in Saltreach. She wanted 40 gold and “a favor, later.” Vex haggled her down to 25 — the favor is still owed.

The fog of war

One question. Two very different answers.

Every read goes through a permission filter. The DM sees the whole board; each player sees exactly what their character has learned — nothing leaks, not even in a shared channel.

Dungeon Master

“What do we know about Marrow Quill?”

Cartographer in Saltreach; sold the party the Vault map.
Owed one favor by Vex.
Secretly an agent of the Drowned Choir — the map leads into their trap.
Her missing eye is in the Vault’s reliquary.

Two things you haven’t discovered yet.

How it works

Pull up a chair.

1
Invite the bot
Add Hearth to your table’s server. Players link up with /join.
2
Play like you always do
Hearth listens in voice and folds each session into the campaign’s memory.
3
Ask anything
In Discord or here on the web — answers cite the session they came from.

Around the fire

Everything your table forgets, kept warm.

Session capture

The bot sits in voice, transcribes each speaker, and turns the night into memory — no note-taker required.

Recaps on demand

“Catch me up.” A tight recap of last session before anyone has finished pouring drinks.

A codex that writes itself

NPCs, places, factions and loot, pulled from play and searchable — each entry cites the session it came from.

NPCs in a heartbeat

Need a shifty harbormaster now? Claude invents one that fits your world, and you keep the parts you like.

DM prep that knows the table

Open threads, who hasn’t had the spotlight, what the party still hasn’t asked about. Yours alone.

Corrections & reveals

Fix what the memory got wrong. Reveal a secret to one character, the party, or everyone — and take it back.
