Tabletop Ledger
Campaign organizer for tabletop RPG game masters: a tree of pages, plus an AI chat that takes whatever page you're on as context.
What it is
A web app for tabletop RPG game masters: the people who prep a session by juggling NPCs, locations, factions, plot threads, and three half-finished encounter notes. Tabletop Ledger lets you organize all of that as a tree of pages with a WYSIWYG editor, and gives you an AI chat that scopes its answers to whichever page you’re currently viewing.
What I built
- Tree-structured page system with a WYSIWYG editor. Game masters organize a campaign as nested pages: a faction has cities, a city has NPCs, an NPC has a backstory and a session log. Editing happens inline without dropping into a separate editor view.
- Context-aware chat panel. The chat takes the current page as context, so a question about an NPC pulls from that NPC’s page rather than the whole campaign. Answers stay scoped, signal stays high.
- WebSocket-based streaming for AI responses. Replies arrive token-by-token over a persistent connection rather than as a single blocking HTTP call, so the UI feels responsive even on long generations.
- Beta with real users. Ran feedback sessions during beta and iterated on UX/UI; measured a 20% lift in user satisfaction across the cycle.
