Tools & Platforms

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.

Codex Cryptica is an AI-assisted worldbuilding and campaign management tool built around a living knowledge graph instead of a folder of loose documents. Every character, faction, location, and event you create becomes a linked entity, so your world stays connected and explorable as it grows. Genre-agnostic across fantasy, sci-fi, cyberpunk, horror, post-apocalyptic, western, steampunk, and more.

Statblock Maker Pro is a free, always-online 5e D&D toolset with no account, no login, and nothing saved to a server. It covers the full prep-to-table pipeline: a creature/statblock maker and item maker (2014 and 2024 rules), a spell creator, a character creator, and a token stamp for VTT art. On the table side, the encounter maker and initiative tracker run combat live, with a combat difficulty calculator that shows 2014 and 2024 difficulty math side by side and a Monte Carlo battle forecast to sanity-check a fight before you run it.

Encounterra is a free, browser-based D&D 5e (2024) combat encounter simulator that helps Dungeon Masters test and balance encounters. Users can build tactical maps, customize characters and monsters, and run encounters repeatedly using strategic AI to explore outcome statistics, combat logs, and replays. Its public version uses SRD 5.2.1 content and is independent and unofficial.

DiceCalc is a TTRPG dice managmeent system for players and GMs. Here's what it does: Roll all of a character's dice simultaneously — see every attack, save, skill, and modifier roll all at once via the Roll All mode with character tabs. Still reroll per macro — long-press any single roll to edit or reroll just that macro without rerolling the rest, even in Roll All mode. In-depth macro inspection — Roll Macro mode focuses on macro options, allowing players to inspect rolls, rename, edit, and sort the macro list. Sort order here is also preserved in Roll All mode. Cryptographically secure random number generation — higher unpredictability, more randomer. Sortable character tabs with up to 100 macros each — whether you're running or playing a campaign, organize by character, encounter, monster, game system, or any other way you like. Every major TTRPG dice mechanic in one app — keep high/low, target numbers (successes), botches, exploding dice, crit detection, multi-roll comma separation for staged (verification) rolls, and yes... push dice! Constraint validation with red-highlighted error feedback — pathological expressions are caught before they run, no infinite loops or broken math. Persistent 300-roll history with timestamps — every roll logged with full roll breakdown and no truncation. Tap-and-hold context menus throughout — edit, duplicate, delete, rename, reroll wherever it makes sense. Localized in 7 languages — English, Spanish, Portuguese, German, French, Italian, Polish, with complete in-app manuals for each. 14-page in-app user manual — every feature documented with examples, no need to leave the app. Supports Android 8.0 and above — runs on devices going back a decade. Custom QWERTY keyboard for macro names — with locale-specific diacritics via long-press. Independent horizontal scroll per output row — nerd out inspecting long expressions, results, and roll details without truncation. Also... I'm giving it away for free till 09/31/2026 11:59:59 (JST). Check the promo section of the website for details. Honest reviews are appreciated.

LoreMonkey is a Windows app that records and transcribes D&D and other tabletop RPG sessions on your own PC. Connect the Discord desktop app and every line is labelled with the character who said it. No bot joins the call and no audio leaves your computer. For in-person games you can record the room with a microphone instead. After each game it writes a recap in your group's own style.  During play it offers short, well-timed prompts drawn from your campaign notes. It also keeps a compendium of your party, NPCs, places, factions and open threads. Ask LoreMonkey answers campaign questions between sessions and cites the sessions each answer came from. Recording and transcription are free and unlimited, it works for both players and GMs, and it supports any game system. Pricing The free tier is free forever. It includes unlimited recording, transcription and speaker labels for one campaign, plus a trial of the AI features (live prompts and recaps). Paid plans are monthly: Lite is $9.99 for one campaign, Standard is $19.99 for unlimited campaigns and adds Ask LoreMonkey, and Pro is $39.99 for several weekly tables. Notes Only one person at the table needs to install it. Speaker labels come from the Discord desktop app, so no bot joins the call. Audio and transcripts stay on the user's PC, and only the AI features send text out. It works with any game system and has separate Player and GM modes.

Session Forge is an offline game master toolkit for fantasy tabletop RPGs, made by Donald Stelling of Digital Underground. Instead of another long PDF, it is a single HTML hub that the GM opens in a web browser and uses at the table to prepare and run sessions. It holds 14 tools: encounters, NPCs, loot, initiative, session notes, dungeons, taverns, quests, rumors, villains, weather and travel, settlements, a one-click one-shot outline, and a short GM playbook. Tools for running the table - Encounter Forge builds fights on an XP budget set by party level, party size and difficulty (Easy to Deadly). Each encounter comes with a motive and a twist, and the creatures are drawn from 198 original 5e-style stat lines. - Initiative Tracker handles HP, AC, conditions, group adds and d20 rolls. Rounds and turn order save automatically, so combat survives closing the browser. Fights made in Encounter Forge can be sent straight into the tracker. - Session Notes saves as the GM types, offers random sparks for quick ideas, and keeps a full archive that can be restored. - GM Playbook explains how to use the tools live without slowing the game down. Generators - Full Session: a one-click one-shot outline with a hook, NPCs, a villain, a journey, two fights, a site, treasure and a twist. - NPC Generator: 8 naming cultures, plus role, voice, quirk, secret and adventure hook, and a "crowd of six" mode. - Loot Tables: common to very rare items, plus gems, art objects and 64 curses. - Taverns & Shops: taverns and shops with priced wares. - Dungeon Builder: dungeons of 3 to 12 rooms, with a boss scaled to the party. - Quest Hooks, Villain Forge and Settlements. - Rumor Mill: rumors with a GM-only truth rating. - Weather & Travel: 6 climates and 4 seasons. On every generator, the GM can lock a line and reroll the rest, go back through a saved history of the last 20 rolls, copy results as text or Markdown, download them as .md or .txt, and send them to Session Notes in one click. Seeds are repeatable, so the same seed always gives the same result. How it works The GM downloads a ZIP, opens index.html and bookmarks it for game night. After that one download, Session Forge runs fully offline with no account. Data is saved in the browser, and the home page has backup and restore. It works in a browser on desktop and on mobile. Systems and fit The stats are 5e-flavored so they feel familiar, and the content is easy to reskin for OSR games, Pathfinder or homebrew settings. All generator content is original; it is not a dump of official rulebook text. Session Forge suits GMs running 5e-compatible fantasy, one-shots and west-marches campaigns, and GMs who improvise and need ideas fast. It is not a virtual tabletop plugin: it runs locally in the browser and does not connect to Foundry VTT or Roll20. Price and license Session Forge is a one-time purchase from CAD$14.99 (pay what you want above that) on Gumroad. The license is personal, single-GM use. Version 2 raised the toolkit from 6 tools to 14, and earlier buyers get v2 free by downloading again; their v1 saves carry over.
