Campaign Home
One view of every session, NPC, location, and quest in flight. Skim before play; deep-dive during prep.
Session prep & scenes
Plan a session as a list of scenes you can flip through at the table. Move pieces between scenes as the night unfolds.
Battle tracker
Initiative, HP, conditions, and party state in a tracker designed to be glanced at — not wrestled with.
Lore & the Codex
Pin locations into a tier hierarchy, link NPCs and quests to anywhere they appear, and pull from a shared codex of spells, monsters, and items.

Help us build it.

GM Squire is in private alpha, and we're building it with the people who'll actually use it at the table. Whether you're prepping your first one-shot or you've been running the same homebrew for a decade, your feedback shapes what we build next.

Drop your email and a line about your table. We'll be in touch when there's a seat for you — and we'll actually listen to what you tell us.
