SpiralWorlds

A portable, offline-first DM and worldbuilding tool. Build worlds, run sessions, share with others and play together, all in one app. License: CC BY-NC 4.0 · Free to use Everything core works **without an account**. You only need one to play online, publish to the marketplace, or download other users' content. /images/general-media/1791564204_7DEx9r3t.webp Worldbuilding - Era Timeline: Split your world's history into eras on a timeline bar and move between them. Each era keeps its own map, pins, nested location maps and day-by-day timeline pins linked to cards and sessions. You can show the same city before the war and after it. - Templates & Packages: Every world is built on a template (D&D 5e is built in) and pulls content from packages. A package is a bundle of cards you can install into any world, link to other packages, or share on the marketplace. Custom templates are coming. - Codex: Schema-driven cards for NPCs, monsters, spells, items, locations and more. Every reference is a tappable link. Pin cards to the top, preview any card with a long press, and search by name, tag, category or text. - World Map: Pins, grid and scale, drawing, fog of war, and nested maps you can walk into (districts, dungeons, taverns). - Mind Map: An infinite canvas with linked nodes, workspaces, freehand drawing and undo/redo. /images/general-media/1791564252_TB7zwrCp.webp Running the Session - Second Screen: Give the table its own view. Pop out a window onto a second monitor, cast to a TV or projector, or project into every connected player's app. You choose how battle maps, images, cards and PDFs go out. Fog of war and hidden tokens stay hidden. - Battle Map: The session screen *is* the map, with the encounter panel and event log on top. It has layers, fog of war, AoE templates, 5e diagonal rules, creature-sized tokens, shapes and text, a DM-only layer, hidden tokens, movement trails for the round, and two maps joined into one. - Combat Tracker: Initiative, HP (with hit-dice rolls), conditions, turn order and an event log. - 3D Dice: Dice roll across the screen with named styles. Skills and saving throws roll from the character sheet with one tap. - Soundpad: Layered ambience with gapless loops, fades and ready-made soundpacks. - PDF Library: PDFs kept inside the world, opened in tabs and shareable with players. /images/general-media/1791564292_BnuuXJTS.webp Characters - Full 5e rules: Species, class, subclass, background and feats fold into one sheet. Each sense, resistance, proficiency, trait and always-prepared spell shows where it came from. Also covers multiclassing, spell slots, class resources (Rage, Bardic Inspiration, sorcery points…), weapon mastery, and short and long rests. - Character Builder: Pick species, class, subclass, background, ability scores, skills, starting equipment and feats from the SRD and any installed pack. - Level-Up: HP, proficiency bonus and hit dice update automatically. ASIs, feats, subclass and spell picks wait as pending choices. /images/general-media/1791564330_JBRRDNZ4.webp Playing Online - Online worlds: Put a world, package or character online and it stays the same on every device you sign in on. Players see the pictures even when the DM is offline. - Players: Join with an invite code, claim a character, move your own token on your turn, and send dice rolls to the DM's log. Shared cards update when the DM edits them. - .dmtz files: Export a world, package or character to one file and import it anywhere. No account or network needed.

Recap Raven is a Discord bot that records Dungeons & Dragons and other tabletop roleplaying sessions and automatically transforms them into detailed, organised campaign notes. It is designed for groups that play over Discord and want to preserve everything that happened withoutasking a player or Game Master to spend the session taking notes. Description With the table’s consent, Recap Raven joins a Discord voice channel and records the game while everyone plays normally. When the session ends, it transcribes the conversation and creates a structured, player-safe recap covering important story events, character decisions, NPC interactions, locations, discoveries, combat encounters, items, clues, quest progress, memorable moments, and unresolved story threads. Recap Raven also creates private notes and preparation context for the GM. Player-facing information is kept separate from hidden knowledge, future plans, secrets, and other GM-only material. These private tools help the GM remember improvised NPCs and locations, review important player choices, track outstanding hooks, and prepare for the directions the party might take next. Every completed session contributes to a searchable campaign memory. Players and GMs can ask questions such as who possessed a particular item, what an NPC promised the party, where an event occurred, which quests remain unresolved, or what happened during a missed session. Recap Raven answers using evidence from the original session transcript, making it possible to verify where campaign information came from. The bot is suitable for long-running campaigns, short adventures, and groups whose session notes have become scattered across Discord messages, documents, notebooks, and memories. Its catch-up summaries also help absent players return to the game without requiring another member of the group to explain the entire previous session. Recap Raven works with Dungeons & Dragons, Pathfinder, Daggerheart, Call of Cthulhu, and other TTRPG systems played through Discord. It allows players to concentrate on roleplaying and storytelling while giving the whole table a campaign record that becomes more useful with every session.

Natural Zero is a tool I build for myself and my group of beginner adventurers. It has a character sheet editor. If you have created your character sheet you can export it as PDF and/or use the Combat copilot to help you not forget anything in a battle. In this tool you can see all options you can take in combat and lists al conditions and active spells as well as health management.  As DM you can create battles with the Battle Composer and roll initiative to track the rounds, you can add your players here. Hopefully in the near future you'll be able to add character sheets your players created by inviting them into your campaign so it's even less manual work to streamline your sessions! I hope you enjoy using Natural Zero

The Adventure Game Engine (AGE) is a tabletop roleplaying game system designed by Chris Pramas and published by Green Ronin Publishing, first introduced in the Dragon Age Roleplaying Game, an officially licensed adaptation of BioWare's video game series. Rather than staying tied to that one setting, AGE was generalized into a standalone toolkit that Green Ronin has since reused across a growing family of otherwise unrelated game lines: Fantasy AGE, Modern AGE, The Expanse Roleplaying Game, Blue Rose: The AGE Roleplaying Game of Romantic Fantasy, and Cthulhu Awakens. Each line shares the same dice math and character-building vocabulary while reskinning them for a different genre, from grim high fantasy to hard-science-fiction space opera. Description Sit down at any AGE table and the character sheet looks familiar whatever the setting: a handful of ability scores, a page of Focuses that narrow down what a character is actually good at, some Talents, and a Health track that goes down rather than up. What changes by line is who's being played and what the group is doing with them. Dragon Age and Fantasy AGE put players in a class-based, sword-and-sorcery world built on the same tropes as the video games. Modern AGE drops the classes in favor of a freeform, contemporary or near-future toolkit for playing civilians, agents, or specialists; The Expanse puts players on a scraping-by crew in a hard-edged solar system where violence is fast and often permanent; Blue Rose asks for heroes of a deliberately hopeful, consent-based fantasy nation. The Game Master narrates outcomes and calls for rolls, and underneath every one of those settings sits the same rhythm: roll, hope for doubles, and spend what's earned on a stunt table built for the scene in front of you.
