StoryGuard is a notebook for Game Masters. Write down what happened at the table, and it keeps track of who's dead, who has the cursed sword, and what your players haven't figured out yet. Then it writes the recap for your group chat.
Any system: D&D 5e, Pathfinder, Call of Cthulhu, Blades, homebrew. No credit card.
Before, during, and after. Here's a session of Tides of Saltmere, the example campaign every new account starts with.
Jot down a rough plan. StoryGuard lays out the rest: last session's recap, open quests and who's tied to them, the loose threads your players will ask about, and the secrets still waiting to be found.
Harvest feast at Mayor Hollis Brand's manor.
Scene 2: if Kestrel shows the seal, Hollis says it was stolen. Captain Marr knows he's lying.
Midnight: a hymn drifts in from the bay…
One clean page for the session, your plan pinned beside it. Type @ to link an NPC. When a player asks the name of the innkeeper you never wrote down, look it up in a second, or add one on the spot.
Feast is loud. Tamsin Vale works the room, Kestrel watches the mayor.
Kestrel slaps the seal on the table. Hollis goes pale, says it was stolen weeks ago.
Party asks the cook's name. It's Bettany now.
Marr nods at Kestrel from the door
Click What changed? and StoryGuard reads your notes: who died, who moved, which item changed hands, which secret came out. Approve what's right and your codex is up to date. Then copy a spoiler-free recap straight into your group's Discord.
StoryGuard checks each session against everything you've established: the dead stay dead, items stay where they were left, and nobody acts on a secret they never found out.
Old Wren died in session 2, but in session 3 she greets the party at the dock.
Give the scene to someone else? Or was it her ghost…
Mark anything as secret: a whole NPC, or just their true allegiance. Recaps leave secrets out until you note the session your players found out. If one slips into a recap anyway, you're warned before you post it.
The prep sheet keeps the list of what's still hidden, so you know which reveals you have left to play.
NPCs, player characters, factions, places, items, quests, events, lore, and house rules, linked together and remembered as they were in every session. Browse it as a map or a list.
Drop in a pack: ready-made NPCs, places, and hooks from StoryGuard and other GMs. Take only what you need. Made something your table loved? Share it as a pack of your own.
Not a virtual tabletop. Keep Roll20, Foundry, or your kitchen table. StoryGuard is the notebook that sits beside it.
Early Access: lock in 25% off, forever, while spots last.
Have your own Anthropic API key? Connect it and AI features run on your key instead.
Yes. StoryGuard doesn't care about rules or stat blocks. It tracks people, places, items, quests, and what happened, so it works for any system, published or homebrew.
No. Players don't have accounts. They only see what you share, like the recap you paste into your group chat, and recaps leave out anything you've marked secret.
Three jobs: after a session it proposes codex updates from your notes (you approve each one), it checks your notes for contradictions, and it drafts the player recap. It never changes anything without you.
Yes. Paste your old session notes in and start from there. The AI can pull NPCs and places out of them as you wrap up each session.
Yes. Your campaign is yours. It isn't used to train AI models, and you can delete your account and everything in it at any time.
