MYTHIC SCRIBE
A 2024 5e (SRD 5.2.1) Solo Campaign Game Engine and Digital Character Sheet built across 2.5 years of prompt engineering by a player through actually playing.A fully-editable character sheet that automatically calculates derived stats to use with an AI Game Master that follows and enforces 5e rules, can't fake dice rolls for narrative flair, won't forget what happened whether it was 20 turns ago or 200, running a living, open world built specifically for your character populated by potential friends and foes alike, and hiding actual loot that ALL exist "behind the GM's screen" before Turn 1.
Closed Beta capped at 50 testers (free Beta turns included) — or play unlimited turns anytime with Free BYOK during Beta.

The AI Never Rolls Dice: Every skill check, saving throw, and attack roll in the game, even attacks against your character, gets printed as a tappable link directly inside the message. Tapping it opens a Dice Roller sheet pre-configured with the correct dice type, number of dice being rolled, if the roll has advantage or disadvantage, and the target DC/AC. Tapping the Copy to Chat button copies the roll to your text field ready to send along with any character action or OOC chat you want to include with it. You can stack all three—a dice roll, an OOC message, and a character action—into one message, the AI can handle it and address each individually in its response. Turns are limited, use them wisely.Live 20-Stat HUD: The collapsible HUD displays AC, Initiative, Passive Perception, and Speed, and tapping them will display a short description at the bottom of the screen for new players. HP, Temp HP, XP, Total Gold, Arrows, Hit Dice, and Spell Slots (up to 9th level) automatically update based on the GM's message, and tapping them allows you to edit them yourself without leaving the chat window.
OOC TABLE CHAT

Out of Character Chat: You can talk Out-of-Character (OOC) with the GM anytime, whether it's to ask a question, ask for help, set a house rule, or just shoot the shit. The rule agreed to in the screenshot above was automatically added to the House Rules section of the Campaign History during the next Archivist run, or you could add it immediately, and it will never be forgotten. Wrap OOC chat in parenthesis and tagged '(OOC: )' just like in the screenshot so the AI knows it's out of character.
LIVING CAMPAIGN HISTORY

No More 20-Turn Amnesia: Standard AI chatbots forget who you are and where you're standing as soon as the context window fills up. In Mythic Scribe, my personal playtest campaign (The Starlight Frontier) is at Turn 274 across 53 Chronicle entries, and the GM still remembers specific gifts bought for NPCs over 220 turns ago. The apothecary vial referenced in the most recent Chronicle entry above is part of a set that Vex purchased for Pippa back on Day 2 - Late Morning in Chronicle entry #27.The Archivist (Automated Background Memory): At the end of every 10th turn while you're reading the GM's message, a background function distills recent events into your 100% player-editable Campaign History:• Campaign Chronicle: A scene-by-scene log of your journey with timestamps and locations. Copy the entire log with a single tap!
• NPCs: Detailed dossiers tracking disposition (Hostile, Neutral, Allied, etc.), personality, current location, and entanglements within the world.
• Quests: Active and completed objectives with rewards.
• House Rules: Custom rulings, Companion stat blocks, and table agreements that the GM permanently enforces.
• Companions: Mythic Scribe includes a custom Companion mechanic. If you get along or fight well with an NPC, ask the GM if you can make them a Companion and they will travel and level up with you. Base Companion Stats are: Primary Stat +3, Secondary +1, AC 14–16, Max HP = 4 + (7 × Lvl), Attack Roll = +3 + PB.
- Tactical Assist (Bonus Action Help): A Companion can use their Bonus Action to take the Help action (granting the PC Advantage on their next attack or check).
- Companion Retaliation: 1/Short Rest, when the PC and Companion are within 5 ft of each other and one is Hit, the other can take an immediate Reaction counterattack against the attacker with Advantage.
2024 5E CHARACTER SHEET
Tap screenshot to view full-screen.
Built for 2024 5e (SRD 5.2.1): Forget manually calculating modifiers or flipping through rulebooks mid-turn. Choose your Species, Class, Background, Skill Proficiencies, and Ability Scores, and the sheet automatically calculates your Skill Modifiers, Saving Throws, Initiative, Passive Perception, Spell Save DC, and Weapon Attack bonuses.• Plain-English Rule Reference: Every weapon property, mastery, spell, and class feature includes its full rule description right on your sheet so you never have to leave the app to look up how an ability works. But if you do have a question that isn't answered in the app, the full SRD 5.2.1 pdf is available in the app for viewing or downloading.
• 100% Editable Anytime: Add custom magic items, homebrew gear, or tweak any stat on the fly.
• Free Live-Tabletop Mode: Playing an in-person game with friends? You can use the Mythic Scribe digital character sheet and 3D dice roller at a live table completely free—no AI turns required.
• The Ghostwriter (Roleplay Assist): Not sure how to phrase your next move? Tap the Sparkles icon next to the chat bar—either on an empty box or with a quick note like "search the desk"—and the Ghostwriter will draft a rich, first-person response tailored to your character's stats, inventory, personality traits, and your previous play style.
BEHIND THE GM'S SCREEN
Tap screenshot to view full-screen.
The Adventure Architect (Bespoke Sandbox Generation): Standard AI chatbots improvise aimlessly from turn to turn. If you tell it 'I open the chest hoping there's a +1 magic sword in it', sure enough there's going to be a +1 magic sword in there because it's making everything up on the spot turn by turn. It doesn't know what's in the box before it describes its contents any more than you do.In Mythic Scribe, before Turn 1 ever begins, a dedicated Adventure Architect AI analyzes your character's description, backstory, class, background, personality traits, ideals, bonds, and flaws (plus any optional genre or setting requests you provide) to construct a massive, bespoke Campaign Blueprint built specifically for your character.• True Fog of War: Just like at a real tabletop, this blueprint is kept strictly hidden "behind the GM's screen." You have to uncover its secrets organically through play.
• A World That Moves Without You: This open-world map is populated with interconnected locations, factions with active agendas that don't revolve around your character (and aren't waiting around for your character to show up before taking action). A roster of NPCs with their own identities, distinct personalities, lives, goals, and hidden motives. Rumors and hooks to chase if you choose, and actual pre-existing magic items and loot tailor-made for your character already placed in the world before you take your first step just waiting for you to discover it. And it's not just a boring +1 sword if you're a fighter or a +1 Stealth item if you're a rogue.
• Balanced for Solo Play: Combat is structured and scales with your character's level. You won't get one-shotted by a CR 5 at level 1, and you won't be fighting CR 1/2 at level 5. Encounter design and world pacing are specifically engineered for a solo campaign, and automatically adjust to a PC and their recruited Companion if they have one, rather than a standard party of four.

ABOUT THE DEVELOPER
Tap screenshot to view full-screen.
Built by a Player for Players: Mythic Scribe wasn't built by a bloated corporate publisher, instead it is the product of a 5e Player who built the game he wanted to play himself. It is independently founded, engineered, and maintained by a solo developer and lifelong tabletop RPG fan who spent 2.5 years engineering the underlying multi-agent AI system through real, long-form solo playing.The Architecture Behind the Curtain: Standard AI wrappers send a single prompt to a chatbot and call it a day. Mythic Scribe coordinates three specialized AI systems—the Adventure Architect for blueprint design, the Game Master for game play, and the Archivist to record the campaign history—alongside a deterministic 2024 5e Character Sheet, automated state-tracking HUD, and interactive dice engine built to deliver the sustainable, long-running AI-driven solo campaign that you've been looking for and have been unable to find.Got feedback, bug reports, or wild campaign stories?
