ReSim Studio / Kartil
Tool for game masters · In development
Create the world. Play in it.
Kartil combines a map editor with a player display for a real table: build rooms, set light and weather – and show the scene to your players on a second screen or in a browser.
Create
Build places that feel lived in
Draw rooms, walls, doors, paths, rivers and terrain. A room is created in one go – floor, walls, doors and fitting furniture, from tavern hall to smithy. Move whole rooms together with their contents.
- GeneratorsDungeons, crypts and caves at the push of a button – then keep building freely.
- LibraryFurniture, plants, lights and terrain by drag and drop.
Atmosphere
Make the scene breathe
Light and shadow, torches, flowing water, rain, fog or embers. Fog of war with line of sight reveals the world as your players explore it – doors open, and the room behind lights up.
- Dynamic visionTokens only see what their line of sight allows. Torches carry their light.
- Weather and time of dayFrom dusk to crypt, from rain to falling ash.
Play
Bring the map to the table
Campaigns with multiple scenes, tokens, initiative, handouts and sound. The player view runs over HDMI on a TV or table screen – or in a browser on your home network. You stay in control on your own screen.
- Scene transitionsFrom the imperial seal to an ink wipe.
- True 1:1 scaleGrid cells match real miniatures on the table.

The name
A small light for vast worlds
Kartil means “small candle” in High Falkan. It is a reminder that the most memorable worlds often begin with a single light on the table.
Stay in the loop
Kartil is still in development. We announce news and chances to test it on our channels and on Discord first.
