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.

GURPS (Generic Universal RolePlaying System) is a tabletop role-playing game designed by Steve Jackson and published by Steve Jackson Games. Initially released in 1986, with its current Fourth Edition published in 2004, it provides a universal ruleset built to accommodate any conceivable genre, setting, or power level. The system is recognized for its high degree of modularity and its strict reliance on point-based character creation rather than traditional classes or experience levels. Description In GURPS, players construct characters by allocating a predetermined pool of Character Points. These points are spent to acquire core attributes, specific skills, and advantages. Players can also elect to take disadvantages, such as physical limitations, phobias, or social stigmas, to gain additional points during the creation process. The game functions primarily as a mechanical toolkit rather than a fixed set of rules. Game Masters are instructed to select only the specific mechanics, combat modules, and magic systems from the core rulebooks and supplemental materials that fit the intended tone and setting of their campaign. System Overview & Key Features 3d6 Task Resolution The system exclusively uses a pool of three six-sided dice (3d6) for action resolution. To succeed at a task, a player must roll a total equal to or lower than their character's modified skill or attribute target number. The use of three dice generates a bell curve probability distribution, which makes average outcomes statistically common and extreme successes or failures mathematically rare. Point-Buy Character Creation Character generation is entirely point-based. The Game Master assigns a starting total of Character Points (CP) to dictate the overall power level of the campaign. Every element of a character, including the four basic attributes (Strength, Dexterity, Intelligence, Health), specialized skills, wealth, and social status, is purchased using these points. Universal Modularity GURPS is structurally designed for adaptation. The core rulebooks provide the foundational mechanics, while hundreds of supplemental books offer optional, granular rules for specific settings, such as cybernetics, realistic martial arts, space travel, or varied magic systems. The ruleset is intended to be heavily customized and scaled in complexity by the Game Master. Tactical Combat and Damage Resistance Combat encounters operate on one-second turns, creating a highly detailed and tactical framework. The system incorporates rules for hit locations, weapon reach, bleeding, and shock penalties. In combat, armor functions as Damage Resistance (DR); it directly subtracts from the numerical damage inflicted by an attack rather than making the target more difficult to hit. Skill Defaults When a character attempts an action for which they do not possess the specific trained skill, the system utilizes a "default" mechanic. The player may roll against a closely related skill or a foundational attribute, applying a predetermined numerical penalty. This mechanic simulates a character attempting an unfamiliar task using their general knowledge or raw physical capabilities.
