About RPG Toolbox

RPG Toolbox is a free, collaborative campaign builder for tabletop RPGs. Your whole table works on the same campaign at once - characters, locations, notes, quests, and dice - and everything syncs across devices without an email signup.

Features

• Character and NPC management with full stat blocks and inventory
• Location and world building on a hierarchical map tree
• Campaign notes, journals, quests, and session logs
• Dice rolling with saved macros
• An AI assistant that reads your actual campaign context
• Real-time collaboration and cross-device sync

Supported RPG systems

• D&D 5e
• Pathfinder 2e
• Star Wars 5e
• Shadowrun
• Tormenta20
• Custom systems

How it works

Campaigns are passphrase accounts - no email address required. Data is stored as Loro.dev CRDTs, which means two people editing the same character offline both keep their changes when they reconnect.

Agents can reach the same campaign over the Model Context Protocol using the same tools as the in-app assistant. Setup instructions live on the agents page.
