AD&D Toolkit is a collection of tools for Dungeon Masters that integrates seamlessly with digital Character Sheets. It is not a VTT.  Its a digital assistant for DMs and Players.  It greatly enhances both in-person and online play by speeding up and automating the more interesting, yet cumbersome mechanics of AD&D. Toolkit supports First Edition(1e), Unearthed Arcana(1e), and Second Edition(2e). Community Across multiple platforms, our membership numbers in the thousands.  If you haven't yet, you need to check it out.  The Discord serves as the community hub as well as offering support for the Toolkit.  It serves as a valuable resource for people new to AD&D or Toolkit. Blog The AD&D Toolkit blog serves as a resource to the public for both Toolkit and AD&D in general.

Obsidian is a free, locally-stored Markdown note-taking application that the TTRPG community has widely adopted as a campaign wiki, session planner, and lore database. Originally designed as a personal knowledge management tool, it stores everything as plain text files on your own machine with no subscription required. Description Unlike purpose-built platforms such as World Anvil, Obsidian was not designed with TTRPGs in mind, which means it arrives without templates, stat block support, or any TTRPG-specific structure out of the box. GMs who want those features need to install and configure community plugins themselves, which carries a steeper setup cost than dedicated alternatives. For those comfortable with that process, however, the result is a highly customizable system with no ongoing fees and no vendor lock-in. A thriving plugin ecosystem has filled most of the gaps, and the tool has become a genuine alternative to subscription-based worldbuilding platforms for technically comfortable Game Masters. The plugin ecosystem extends well beyond what is listed here, with community tools covering everything from database-style note querying and cross-device sync to interactive maps and combat automation. A full directory is available at community plugins.

Trails Weaver is a visual worldbuilding app for game masters, worldbuilders and writers. Every character, location, faction and item is a page with rich text, images, custom properties and a relations table, and any page can also be dropped onto a board. There are four board types: - an infinite free board where element cards nest inside other element cards. - map boards with pins, regions and roads that reveal more detail as you zoom in. - hierarchy boards for family trees and chains of command. - relationship graph that assembles itself from the relations recorded on each page Anything marked secret stays hidden when a world is shared through a read-only public link. The free plan covers one world, unlimited free-boards and up to 25 world elements. Pro removes every limit.
