Everything your world needs · in one place
01

Plan and log every session

Outline what's coming, capture what actually happened with quick typed commands, and tie each session to its in-world date. Toggle the built-in commands you use and add your own, so the session bar fits the way your table plays.

Everything is an entity, and you define it

Characters, locations, items, factions, starships, whatever your world needs. Build your own types and attributes, then link it all together with relationships and automatic backlinks.

Maps your table can explore

Upload maps and drop pins that link straight to your locations, with layers and separate GM and player views. Reveal the dungeon room by room as the party explores.

Run the whole app from the keyboard

Hit a single shortcut from anywhere to add an entity, capture a thought, wire up a relationship, jump to a page, or export your world. Fully customizable, so the commands you reach for most are always a keystroke away. And when the lights go down, the whole workspace dims with them: dark, light, or system, with nine color schemes.

The RPGUni command palette open over a city map, listing typed commands like find, search, add, think, relate, export, and goto with keyboard hints.

Time that works the way your world does

Design fantasy calendars with custom months, weekdays, moons and seasons, compute moon phases, and pin in-world dates to anything in your universe.

The RPGUni Calendars view showing the Calendar of Harptos with a 10-day week, the month of Hammer in year 1492 DR, moon phases, and color-coded seasons.
