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.

Threadfall is a campaign management platform built for live tabletop role-playing games. It records the session, transcribes speech in real time with speaker diarization, and turns the resulting transcript into a recap, a running campaign codex, and a live screen for the table, so the Game Master can stop taking notes and focus on running the game. The product was built by a Game Master frustrated with the gap between what happened at the table and what survived to the next session. Notebooks, spreadsheets, and post-session memory dumps consistently failed to keep up with multi-session campaigns where NPCs accumulate, loose threads multiply, and the party's choices weeks ago suddenly matter again. Threadfall treats the session itself as the source of truth: whatever was said at the table becomes structured, searchable, and remembered. Description What it does at the table During a live session, Threadfall captures audio, transcribes it in real time using state-of-the-art automatic speech recognition, and identifies who is speaking. A live screen, designed for a second monitor, a tablet at the table, or a shared display, shows the unfolding session in a clean, distraction-free view. The Game Master sees recent dialogue, current scene context, and tracked entities without breaking flow. What it does between sessions When the session ends, Threadfall produces a recap that captures what actually happened, character actions, key dialogue, decisions, and consequences: drawn from the transcript rather than from the GM's memory. It updates the Living Codex: a structured repository of characters, locations, factions, items, and plot threads that grows automatically as the campaign progresses. Entities are extracted, relationships are mapped, and the codex is searchable from the next session onward. Who it's for Game Masters running ongoing campaigns, particularly online or hybrid groups using voice chat, but equally useful for in-person tables with a recording device. It's system-agnostic: nothing in the product assumes Dungeons & Dragons or any specific rule set. It's been built and tested against D&D 5e and 5.24, but works equally well for Pathfinder, Call of Cthulhu, indie systems, and anything else where a group of people talks for hours and the GM has to remember it all. Free tier New users get two complete live sessions and recaps to try the product, with no credit card required. Founder rate Game Masters who subscribe during the launch window receive a Founder rate of $7.99/month for as long as they remain subscribed, including three campaigns, six AI sessions per month, the full Living Codex, and the live screen. Technical foundation Threadfall is built on real-time speech-to-text with speaker diarization, large-language-model summarization and entity extraction, and a knowledge-graph backend for the campaign codex. The infrastructure is designed for the unusual demands of multi-hour, multi-speaker, jargon-dense sessions where the participants invent proper nouns on the fly. Independent and actively developed Threadfall is built by an independent developer who is also an active Game Master and player. The product is shipped iteratively, with bug fixes and features released as feedback comes in from the founding group of Game Masters using it weekly.

Star Wars: The Roleplaying Game - retroactively nicknamed Star Wars d6 to distinguish it from later games sharing the same title - is the original licensed Star Wars tabletop RPG, designed by Greg Costikyan and published by West End Games from 1987 until the company lost the license in 1998. It ran on the D6 System, adapted from rules Costikyan and colleagues had built for the 1986 Ghostbusters RPG, and its emphasis on speed and cinematic flair over rules complexity made it a strong match for the trilogy's pace.  The game passed through three main rulebook versions - 1st Edition, 2nd Edition, and 2nd Edition Revised and Expanded - before the license moved to Wizards of the Coast for a d20 version in 2000, and later to Fantasy Flight Games (2012-2020) and then Edge Studio, an Asmodee subsidiary, who currently hold it. It won the Origins Award for Best Roleplaying Rules in 1987, and its sourcebooks were considered canonical enough that Timothy Zahn was reportedly handed a box of them as reference material when writing the Thrawn trilogy - Fantasy Flight Games released a deluxe 30th Anniversary reprint of the original rulebook and sourcebook in 2018. Description Playing Star Wars d6 means playing smugglers, rebels, bounty hunters, or Force-sensitive heroes across the classic trilogy era - and, through later sourcebooks, well beyond it - using a system built to move fast and feel cinematic rather than simulate every detail. Skill checks roll a pool of six-sided dice tied to a broad Attribute, like Dexterity or Knowledge, plus any specific skill dice a character has invested in, with one die always a different color: the Wild Die, which can either blow a roll wide open on a 6 or threaten a complication on a 1.  It's a rules-light, pulpy game built to run a session the way the original trilogy actually plays - fast banter, faster blaster fights, and Force powers that feel genuinely special.

FreeVTT is a browser-based virtual tabletop (VTT) application designed to facilitate the play of tabletop role-playing games. Positioned as an accessible alternative to subscription-based platforms, FreeVTT operates entirely free of charge and requires no user registration. The platform is built with a focus on user privacy and local data management, utilizing the user's device for storage rather than centralized cloud servers. It provides a suite of essential digital tabletop utilities, including map rendering, token manipulation, and combat tracking, without implementing premium feature tiers. Description FreeVTT functions as a digital tabletop environment intended for both remote and in-person game sessions. In contrast to many prominent VTT platforms that mandate account creation and rely on external servers to host campaigns, FreeVTT functions entirely within the local cache of the user's web browser. This architectural choice ensures that no user data is collected or transmitted, enabling immediate gameplay without a login process. Furthermore, the application integrates open-license rule systems directly into its interface, providing accessible compendiums for the 2014 and 2024 editions of Dungeons & Dragons 5e, alongside Pathfinder Second Edition.
