Chartwright is a random table tool for tabletop RPG game masters, built around one idea: tables that link to each other.

Roll on your wandering monster table, and it automatically rolls on the monster's reaction. Roll on a city encounter, and it triggers an NPC name, a quirk, and a reason they're there. Build the system once. Run sessions forever.

LINKED TABLES, NOT FLAT LISTS

Most random table tools give you a list. Chartwright gives you a system.

Build encounter tables that chain into reactions, treasure tables that roll for both items and their conditions, NPC generators that produce full personalities in one tap. Your tables become a connected toolkit instead of isolated pages.

WEIGHTED ENTRIES

Make common results common and rare results rare. Each entry has a weight that controls how often it appears, so your loot table can have a 50% chance of basic gear and a 0.01% chance of a legendary find, without padding the table with filler.

FEATURES
- Create custom random tables of any size
- Weight entries to control probability
- Link tables so one roll triggers connected tables automatically
- Roll instantly with a tap
- Sync between your phone and the web app at chartwright.app
