🚀 What is GameMasterBuddy

GameMasterBuddy (GMB) is a web app built for tabletop RPG Game Masters. You use it from your browser, with nothing to install, and it is fully bilingual Italian/English. It started as an engine that indexes your game manuals (the PDFs) so you can query them, and today it is a complete workbench: a chat that answers by quoting the manuals, a character creator, AI-generated portraits, tabletop tools, a map editor and an online table for play.

Who it's for

GMB is made for the person running the game, not for casual players. It helps you in the three moments where a GM struggles most:

• Before the session (prep): build non-player characters, one-shot adventures, battle maps and ready-to-use stat sheets.
• During the session (at the table): dice rolls, initiative tracker, on-the-fly generators (names, taverns, encounters, loot), timers and notes always at hand.
• When you need a rule: ask the Master AI chat and get an answer that quotes the real manuals, instead of making things up.

What's inside

GMB brings together in one place the tools that are usually scattered across PDFs, spreadsheets and different sites:

• Master AI — the chat that searches the manuals and answers with sources.
• Character creator — for Vulcania and for D&D 5e/Eberron, saved to your account.
• Portraits — AI-generated images for your characters.
• One-shot Studio — generates a playable adventure step by step.
• Tabletop tools and the Bench — dice, tracker, generators, stat sheets, timers, notes and a composable block canvas.
• Cartographer — the top-down map editor.
• Online table — the virtual tabletop with map, tokens and fog of war to project to players.
• Campaigns and Library — where you organize your games and find everything you've made.

How it works in short

Most of GMB runs directly in your browser: the tabletop tools and the maps consume nothing and are free. Only the features that use artificial intelligence (the Master AI chat, the DM helper, Portraits and One-shot Studio) spend credits, which you receive every week. Access is currently a closed beta: you sign up with a form and an administrator approves you.
