The short answer

What is the best AI dungeon master for solo D&D?

For solo D&D, LoreWeaver is our top pick: its Loom rolls dice checks in code (1d20 against DC 12 for a risky move) and tracks health, XP, quests, and inventory, while the storyteller writes campaign memories every 4 replies. AI Realm suits players who want a 5e character sheet with click-to-roll dice, and Friends & Fables runs turn-based 5e combat on battlemaps for parties of up to 6. AI Dungeon remains the classic for shared and scripted adventures, and SillyTavern suits tinkerers who want to pick their own model.

The reviews

What each one does best, and who it suits.

LoreWeaver: Best for solo campaigns with dice and memory

Dice and rules: 1d20 checks against DC 12, rolled in code
Campaign memory: Memories every 4 replies, a recap, lore cards
Free option: 20 guest replies, then a free plan
Paid plans: $7.99 to $49.99 a month
Runs on: Web, Android; iPhone soon

On LoreWeaver a storyteller runs the world and everyone in it, and you play your character. For D&D-style campaigns the Loom adds the rules: when you try something risky, it rolls 1d20 against DC 12 in code, and the storyteller narrates the result it was given.

Where it wins: Rules and records. Of its 53 Loom templates, ones such as Skill Checks, Dice Combat, Boss Fight, Health System, Leveling & XP, Quest Tracker, and Inventory & Keys add checks and trackers in one click, and the HUD shows health, XP, quests, and inventory while you play. Every 4 replies the storyteller writes memories that name who was there and where, recalls them by meaning, wording, and who is in the scene, and keeps a running recap you can edit, pin, and add to. Lorekeeper suggests lore cards for new NPCs and places, and branches let you replay a choice from any reply, with a tree view of every path.
Where it falls short: It’s built for one player per story. Friends can each play their own copy of a world you publish, but they can’t sit at one shared table.
Price: Free to start with 20 replies in any Hub world and no account, then a free plan with unlimited replies from the fast free storyteller and 25 premium replies a day. Plus costs $7.99 a month, Pro $14.99, Ultra $24.99, and Legendary $49.99 with unlimited premium replies. The Loom and its templates come with every plan.
Pick it if: you play alone and want dice rolled by rules and a campaign whose first session still matters in its fortieth. Describe a setting in one sentence and the world builder makes it playable, or read how to play D&D solo with AI.

AI Dungeon: Best for shared and scripted adventures

Dice and rules: Adventure Scripts can roll dice and track stats
Campaign memory: Summary every 15 actions, Memory Bank
Free option: Free tier, 4K tokens of context
Paid plans: $14.99 to $99.99 a month
Runs on: Web, iPhone, Android

AI Dungeon, from Latitude, is an AI text adventure game. You take turns with Do, Say, and Story actions, ask for a picture with See, and start from your own setting or one of thousands of community scenarios.

Where it wins: Group play and scripting. Multiplayer games take a join code with no set limit on players, and only the host needs a subscription for everyone to share its benefits. Scenario creators can script how a turn works, and published Adventure Scripts can roll dice, track stats, and create story cards for you. Its memory summarizes the adventure every 15 actions and keeps a Memory Bank of key moments.
Where it falls short: Dice and stats come from scripts, so they vary with the scenario or script you choose. The free tier keeps up to 4K tokens of context and 25 memories.
Price: Free to play. Journey costs $14.99 a month, Legend $29.99, Mythic $49.99, and Ultimate $99.99, each with monthly credits.
Pick it if: you want to run adventures with friends, or tinker with scripted scenarios. Compare AI Dungeon and LoreWeaver.

AI Realm: Best for a 5e character sheet with click-to-roll dice

Dice and rules: 5e SRD rules; click a stat or skill to roll
Campaign memory: Notes; a campaign summary about every 8 messages
Free option: Free plan, no credit card
Paid plans: Four paid tiers, Bronze to Obsidian
Runs on: Browser; installs on phones

AI Realm is built on D&D 5e SRD (2014) content. You make a character with a race, class, background, and abilities, and an AI game master runs the campaign from there, in the browser or installed on a phone or tablet.

Where it wins: Character sheets. Click an ability score, skill, save, attack, or damage to roll dice, and the AI updates HP, level, gold, XP, AC, and items as you play. NPC Cards hold up to 30,000 characters each, GM Guides cover places and house rules, and you and up to 3 friends can play together, depending on plan. It offers 29 storytelling models and 3 image generators.
Where it falls short: Campaign memory rests on Notes. Its own guide says that if something isn’t in your Notes, the AI will eventually forget it, and Notes share a context limit that starts at 70,000 characters on the free plan.
Price: Free to start, with no credit card. Paid plans run from Bronze through Platinum and Emerald to Obsidian, and premium models need a subscription; its guides don’t list prices.
Pick it if: you want D&D-style sheets and rolls, or a table for up to four players. See the AI Realm alternative.

Friends & Fables: Best for group tables with 5e combat

Dice and rules: Turn-based 5e combat with battlemaps
Campaign memory: Long-term memories on every plan
Free option: Up to 25 turns a day
Paid plans: $19.95 to $39.95 a month
Runs on: Desktop, tablet, and mobile

Friends & Fables is an AI D&D game run by Franz, its AI game master, with tactical turn-based combat based on D&D 5e rules, battlemaps, spells, and monsters. In May 2026 its team said it is moving into more of a maintenance mode while they build a new game called Craft, and that they have no plans to shut it down.

Where it wins: Playing as a group. Parties hold up to 6 players on Legend, friends can join your campaign for free, and every plan keeps long-term memories. Paid plans add unlimited standard turns, text to speech, and bonus credits.
Where it falls short: Updates are coming more slowly in maintenance mode, and the free plan stops at 25 turns a day.
Price: Free for up to 25 turns a day. Starter costs $19.95 a month, Pro $29.95, and Legend $39.95, each with unlimited standard turns.
Pick it if: your group meets regularly and wants 5e combat on a battlemap. See the Friends & Fables alternative.

Infinite Worlds: Best for player-made worlds with pictures

Dice and rules: Tracked items and an evaluation of each action
Campaign memory: Short- and long-term memory, a Summary AI
Free option: Daily free turns
Paid plans: Credits for each turn
Runs on: Browser

Infinite Worlds, from the solo studio Friendly Fox Games, launched in browsers in February 2024. You play worlds other players built, or generate your own from a prompt, and each turn is paid for in credits once your daily free turns run out.

Where it wins: Ready-made and generated worlds. Its World Generator builds every part of a world from one prompt, and authors can add tracked items, keyword instruction blocks, and evaluation instructions that judge each action. A Summary AI (currently Kimi K2.5) condenses past turns and keeps character notes current, and pictures typically cost 3 to 5 credits each.
Where it falls short: The cost changes from turn to turn. Its wiki calls the per-turn prices in the model menu estimates, because each turn is priced by how much text goes in and comes out.
Price: Daily free turns on the model you choose, then credits for each turn. Creating a world and making pictures cost credits too.
Pick it if: you enjoy trying worlds other people built, with pictures along the way. See the Infinite Worlds alternative.

SillyTavern: Best for building your own game master

Dice and rules: /roll from its D&D Dice extension; your own prompts
Campaign memory: World Info, auto summaries, chat vectors
Free option: Free software; you bring the model
Paid plans: None; model costs are separate
Runs on: Windows, macOS, Linux; Android via Termux

SillyTavern is free, open-source software you install yourself. It has no AI of its own: you connect a model from a service such as OpenRouter, OpenAI, or Claude, or run one on your own computer, then shape the game master with prompts, characters, and extensions.

Where it wins: Control over every part of the table. World Info entries add lore when their keywords come up, the Summarize extension keeps an automatic summary of the chat, Chat Vectorization brings back relevant older messages, and the D&D Dice extension adds a /roll command for dice formulas.
Where it falls short: Setup takes some technical comfort, iPhones and iPads can’t run it, and local models need a GPU with at least 6GB of VRAM.
Price: Free under the AGPL-3.0 license. Any cost comes from the model service you connect, or from the hardware you run models on.
Pick it if: you like building your own setup and want to choose the model behind your game master. See the SillyTavern alternative.

NovelAI: Best for private, text-first adventures

Dice and rules: Text Adventure commands: look, inventory, examine, move
Campaign memory: Lorebook entries triggered by keywords
Free option: Trial of 50 text generations
Paid plans: $10 to $25 a month
Runs on: Browser, installable as a web app

NovelAI is a story generator with a Text Adventure mode. In that mode you say what your character does or says, and short commands work the way they did in classic text games: l to look around, i for inventory, x to examine something, and compass directions to move.

Where it wins: Privacy and control. Stories are encrypted in your browser before they’re stored, so NovelAI can’t read them, and lorebook entries join the context when their keys appear, so a campaign’s NPCs and places come back by name.
Where it falls short: The free trial is 50 text generations, given once, and the largest context, up to 28,672 tokens, needs Opus.
Price: Tablet costs $10 a month, Scroll $15, and Opus $25. Accounts are for adults 18 and over.
Pick it if: you like classic interactive fiction and want your campaign kept private. See the NovelAI alternative.

Perchance: Best for quick one-off game master sessions

Dice and rules: Varies; remixes add stats and dice checks
Campaign memory: Varies; remixes add lorebooks
Free option: Free, unlimited, no sign-up
Paid plans: No payment needed
Runs on: Browser

Perchance is a site of free, community-made generators. Its AI RPG page runs a text adventure with an AI game master that is free, unlimited, and needs no sign-up, and players have remixed it into many variants.

Where it wins: You can start a campaign in seconds, with no account and no payment. Remixes add more structure: Emberfall uses stats, dice checks, abilities, loot, and leveling, and Enhanced RPG adds a lorebook with trigger words and story branches.
Where it falls short: Each remix is made by a different person, so features differ from one page to the next, and you may need to try a few.
Price: Free. Perchance’s terms say its services are for adults 18 and over.
Pick it if: you want to try an AI game master tonight without signing up for anything. See the Perchance alternative.

Questions

Before you choose, answered.

01Can an AI be a good dungeon master for solo D&D?

Yes, if the app keeps the rules and the record for it. On LoreWeaver, Loom templates roll checks in code and track health, XP, quests, and inventory, while memories written every 4 replies keep the campaign straight. AI Realm and Friends & Fables build on D&D 5e rules, and AI Dungeon’s scripts can add dice and stats to a scenario.

02Which AI dungeon master rolls real dice?

LoreWeaver’s Skill Checks template rolls 1d20 against DC 12 in code and tells the storyteller how the roll landed before it writes the scene, and Dice Combat and Boss Fight do the same for fights. AI Realm rolls when you click a stat, skill, save, or attack on its character sheet, SillyTavern adds a /roll command through its D&D Dice extension, and AI Dungeon’s Adventure Scripts can roll dice too.

03Which AI dungeon master remembers a long campaign?

LoreWeaver writes memories every 4 replies that name who was there and where, recalls the ones that fit each scene, and keeps a running recap and lore cards for the campaign’s NPCs and places. AI Dungeon summarizes the adventure every 15 actions and keeps a Memory Bank, Friends & Fables keeps long-term memories on every plan, and Infinite Worlds runs a Summary AI over past turns. AI Realm keeps Notes, and its own guide says anything left out of them will eventually be forgotten.

04Can I play AI D&D with friends?

LoreWeaver is built for one player per story; friends can each play their own copy of a world you publish. For one shared table, Friends & Fables seats parties of up to 6 depending on plan, AI Realm seats you and up to 3 friends, and AI Dungeon’s multiplayer takes a join code with no set limit on players.

05What is the best free AI dungeon master?

LoreWeaver lets you play 20 replies in any Hub world with no account, then gives you a free plan with unlimited replies from the free storyteller and 25 premium replies a day, with the Loom’s dice and trackers included. Perchance’s AI RPG is free and unlimited with no sign-up, Friends & Fables allows 25 turns a day free, and AI Dungeon, AI Realm, and Infinite Worlds all have free ways to start.

06Is Friends & Fables shutting down?

No. In May 2026 its team said Friends & Fables is moving into more of a maintenance mode while they build a new game called Craft, so updates will come more slowly, but they have no plans to shut it down.
