MissiveKeep

About MissiveKeep

Missive Keep is a controlled-reveal tool for tabletop GMs. Prep your players' handouts, letters, maps, portraits, item art, anything they should eventually see, then decide exactly who sees what, and exactly when, at the table.

WORKS WITH NO SIGNAL
This app is built for basement games and bad wifi. Sign in once and everything runs from a copy on your device from then on; adding players, writing missives, importing images, and flipping reveals all work with zero connection. Nothing you do at the table waits on a network. When you're back online, it syncs up quietly on its own.

ONE GAME, THREE TABS
- Missives: your reveal grid. See every handout and who's seen it, and flip reveals with a tap.
- Players: add the people at your table. Each one gets their own private link, no account needed on their end, to view whatever you've revealed to them, from any browser.
- Add: write a text missive or drop in an image from your device. New missives start hidden from everyone until you choose to reveal them.

HAND OFF THE TABLET
Player mode turns your device into a shared display: players pick their name and see only what's been revealed to them, and can't wander into GM tools; a gesture lock keeps it that way until you draw it again. While online, player mode quietly re-syncs every 20 seconds, so you can keep driving reveals from your phone's browser while the tablet sits at the table.

PLAYER-FACING, ON PURPOSE
Missive Keep holds only what your players are meant to see, never your private prep, NPC notes, or session logs. It's a delivery tool, not a wiki: the thing it does, it does without getting in your way.
