GM Terminal Kit

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. Content - SRD 5.2.1: Built in and works offline. - 19 one-tap packs: Tome of Beasts (1–3, 2023), Creature Codex, Monstrous Menagerie, Black Flag SRD, Deep Magic, Tome of Heroes, Vault of Magic, Tal'Dorei and more. - Ready-made worlds: 99 Devils of Uzrah's Palace (Shadowdark), Army of the Damned, The Cold Bounty, and soon our own campaign Aegis Act . - Marketplace: Publish worlds, templates, packages and characters as versioned snapshots with content previews. - Social: Profiles, follows, an activity feed, direct and group chats, and game listings with applications.

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.

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.

This tool was created to help all gamers play their favorite TTRPG or Roll and Write games even when they are traveling and don’t have access to all the necessary dice and random tables. The tool allows you to load one of the games that are already available or create your own in the editor section. If you don’t want to use the editor, you can also upload a simple JSON file following the expected structure.

Lore Warden is a battle chronicle tool for tabletop wargamers. After a game, players record the essentials: who fought, the forces involved, the score, which units were destroyed and the MVP.Lore Warden writes the engagement up as a piece of prose they can keep, share, and have read aloud. It is deliberately system-agnostic. Faction and unit names are free text and are echoed back exactly as they were typed, so it serves 40k, Age of Sigmar, Necromunda, Mordheim, historicals, BattleTech or a homebrewed ruleset equally. Army lists can be pasted in whole and unit names are picked out automatically, and added/edited manually. There are three ways to use it. A single battle produces one self-contained tale. A tournament tracks rounds, wins, draws, losses and total points, with Swiss pairings and a recap for each round. An eternal war is an ongoing group campaign, where forces evolve over months, eras are marked, retired armies are given a final entry and honours ledger, and the whole thing can be brought to a close with a finale when the group wants an ending. What separates it from pasting a game into a general chatbot is continuity. Lore Warden holds each commander's force and everything that has already happened to it, so a campaign reads as one narrative rather than a series of unconnected write-ups, and it does not invent units that were never on the table. Commanders who would rather write their own account can do that instead and still have it recited. Opponents do not need accounts. A battle can be shared by code or QR for the other player to attach their force, or entered on their behalf as a guest, and every finished tale gets a public page that anyone can read or listen to without signing up.  Written tales are free, thirty of them, for the lifetime of the account, along with one spoken recital. A subscription lifts the written cap and adds a monthly allowance of spoken recitals.
