A dash means the product's own pages don't say, so we haven't claimed it. Three more good ones (Questner, Old Greg's Tavern and NovelAI) are free to try, then paid, so they're listed separately below.

The 9 best free AI RPG games

1. AI Dungeon: best for total freedom

AI Dungeon put AI text adventures on the map. You type actions ("do"), speech ("say") or narration ("story"), and the AI continues the tale wherever you push it. Its library of community scenarios, built up over years, is enormous.

What it does best: raw open-endedness. No other game here follows you off the rails as willingly.

Who it suits: players who value freedom over structure and accept occasional AI weirdness, like forgotten details or tonal swerves. The free tier has no action limits, and paid plans ($14.99 to $99.99 a month) unlock stronger models and a longer memory. It can also make images, short video and voice narration on request, paid for with credits.

Our AI Dungeon alternatives guide covers the rest of that market.

2. Mythx AI: best for an illustrated living world

Full disclosure: this is our app, so weigh this entry accordingly.

Mythx AI is an AI RPG and AI roleplay game set in 13 living worlds, from a cozy fantasy village to a Victorian London district and a magic academy. You arrive as the newcomer. The cast has jobs, routines and relationships, and they remember what you've said. It also plays like an AI choose your own adventure: type any choice you like, or tap one of the suggested moves.

Every scene on Premium comes with an AI-generated image, and characters keep the same face and outfit from scene to scene. Free play is 10 scenes a day; your first scenes come illustrated, then free scenes continue in text.

The same companion across a full in-game day — morning at the well, dusk at your door, night at the inn.

What it does best: visual continuity in a world that holds together. Seeing the same companion across a whole day changes how attached you get to the story.

Who it suits: players who want something closer to an illustrated campaign, with no setup. It runs in the browser and on iOS and Android, with 22 art styles to pick from. Every Mythx story also opens like an isekai AI game: you arrive as the outsider in a world that already exists.

The trade-offs: it's narrative play with no dice or character sheets, it's single-player, and it's a filtered app. Premium is $4.99 a week, $9.99 a month or $79.99 a year for unlimited story and 100 illustrated scenes a day (pricing).

3. AI Realm: best for D&D 5e rules with a free tier

AI Realm is an AI game master built on the D&D 5e SRD: classes, spells, skills and combat, with character sheets, image generators and a choice of AI models. The free tier needs no credit card. Its Player's Guide says you and up to three friends can play together, depending on your plan.

The trade-offs: memory leans on notes you keep, and its own guide warns, "If it's not in your Notes, the AI will eventually forget it." Pictures are made on demand, and it installs to your phone's home screen rather than from an app store. More in our AI Realm alternatives guide.

4. Friends & Fables: best for real D&D 5e with a party

Friends & Fables is a D&D 5e AI RPG where an AI game master named Franz runs a campaign with real mechanics underneath: character sheets, dice rolls, combat and battlemaps. Parties of up to six play on its top plan, and only the host pays. It also has the deepest world-building tools in the genre.

What it does best: marrying AI narration to real rules. When the game master calls for a roll and your stats matter, outcomes feel earned.

Who it suits: D&D players who can't get a group scheduled, or anyone who wants crunch with their story. The free tier gives you 25 turns a day, with paid plans from $19.95 a month. Worth knowing: its team paused big new updates until 2027 to focus on a new product. See our Friends & Fables alternatives if it isn't quite right.

5. RoleForge: best for dice the AI can't fudge

RoleForge pairs an AI game master with a rules engine the AI can't override. Ability checks, advantage and real damage rolls are calculated, on hand-drawn tactical maps with fog of war. Its own pitch: "The AI tells the story. The dice tell the truth."

The trade-offs: it's in alpha, so expect rough edges, and it's solo for now, with co-op on its roadmap. It's free during the alpha, every ruleset included, which makes it an easy one to try.

6. Hidden Door: best for playing inside a story world

Hidden Door builds story games inside curated worlds, including classics like Dracula's castle and Oz, where an AI narrator runs the story with that world's cast. Writers can build and publish their own worlds with its Atlas tool. It runs in the browser.

The free plan gives unlimited stories and turns a day in up to five worlds from the catalog, plus one private character conversation a day. There's no pay-per-turn meter.

Who it suits: readers first, gamers second. It's for people whose dream isn't "infinite anything" but "let me actually walk around in that book."

7. Everweave: best for D&D on your phone

Everweave is a D&D adventure on the web, Google Play and the App Store. Pick a class (fighter, paladin, warlock, barbarian, rogue, cleric or monk), and an AI game master adapts the quest, the dialogue and the fights to what you do.

It's free to start with a monthly message allowance, which regular players outgrow. Plans in its App Store listing run $5.99 to $54.99 a month. It's one adventure style rather than a sandbox with custom worlds.

8. Character.AI: best for character dialogue

Character.AI is AI roleplay chat rather than an RPG with dice and inventory. You pick or create a character, from a rival swordmaster to an "RPG game master" persona, and talk. Community characters number in the millions, and many are built to run a light campaign inside the chat.

What it does best: character voice. The core experience is free with ads; paid plans trim the ads and slow mode (only c.ai+ removes ads entirely) and add more memory.

Who it suits: players who care more about relationships and dialogue than mechanics. The trade-off is structure: memory pins and a Lorebook help, but there are no stats or inventory, it's strictly filtered, and long sessions can drift. Our Character.AI alternatives guide covers the wider field.

9. Imagina RPG: best for authored worlds and your pick of model

Imagina RPG narrates authored worlds with their own lore, characters and story beats, and lets you switch between models like Claude, Gemini and DeepSeek at any turn. Worlds can add real dice and an optional LitRPG layer with level-ups. Multiplayer has been in open beta since September 28.

The trade-off is the free tier: 50 credits a day, and a turn on the default model "typically costs somewhere between 20 and 30 credits," per its credit guide. That's about two turns a day. Turn images are off by default and cost extra, and there's no store app yet. Our Imagina RPG alternatives guide covers it in depth.

Also worth a look

These three are good, but their free play runs out, so they aren't on the free list.

• Questner is a text AI game master with a big community library of campaigns, from fantasy and isekai to cultivation and horror. New players get 40 free messages and a 7-day trial, then it's $9.99 a month for 3,000 messages (FAQ). See our Questner alternatives.
• Old Greg's Tavern is an AI game master for groups: up to five friends join free, on the web or in iOS and Android apps. Your first hour is free, then the host pays by the round, from $5 for 50 rounds to $25 a month for 450 (pricing). It's 18+ only. See our Old Greg's Tavern alternatives.
• NovelAI is a writing tool with a Text Adventure mode in the AI Dungeon mold, plus Lorebook entries that keep long stories coherent. It's a subscription from $10 a month, with a trial rather than a lasting free tier.

How to choose

• Memory. Does the game remember your companion's name, your promises, the tavern you burned down? Look for persistent character memory or lorebooks you can edit.
• Pictures. Text-only is fine, but if you want images, check that characters stay recognizable from scene to scene.
• Rules or freedom. AI Realm, Friends & Fables and RoleForge give you real dice. AI Dungeon and Mythx let you say anything in your own words.
• Free play that lasts. Run each free tier dry before you pay. These limits change often.

Every game here plays better when you arrive with a character and a hook. If you're staring at a blank prompt, run your idea through our plot generator first.
