Public AI RPG Games

16 of the best AI RPGs you can play right now. Filter by model, or by genre.

The public games directory covers the best AI RPGs you can play right now — published Custom GPTs, Claude Projects, and Gemini Gems that are available today, rated and sorted by model and genre. These are community and studio releases that run on the frontier models: games where ChatGPT, Claude, or Gemini is the game master and you are the player.

Filter by model to find experiences built for your AI of choice, or filter by genre to find the tone and setting you want. Every entry has been reviewed for playability and depth — not every AI RPG in the wild holds together past the first session, and the ones listed here do. Use the filters below to find your next campaign.

GPT

8-Bit Kingdoms

A generational dynasty-management RPG that ages, kills, and replaces your ruler every five years — one of the more genuinely novel structures in the Custom GPT store.

Fantasy · Kingdom Builder · Strategy

GEM

Burning Sun V2

A world-agnostic simulation RPG prompt for Gemini with proto-reactive NPCs and switchable storyteller modes — novel and capable, but generalist to the point of cliché.

Roleplay · Simulation · Multi-Genre

CLA

Classic Text Adventure Prompt

A throwback prompt that turns the model into an old-school room-by-room text adventure — simple, coherent, and exactly as deep as that sounds.

Fantasy · Exploration · Roleplay

GPT

Deep Saga

A prompt-only Custom GPT that spins up dangerous, illustrated Sagas across fantasy, sci-fi, and horror — competent, but only as deep as a single prompt with no reference files can get.

Fantasy · Sci-Fi · Horror

GEM

Gamekeeper RPG Prompt

The simplest possible AI RPG prompt — a gamekeeper narrates, a JSON block tracks your inventory, and that's the entire system.

Fantasy · Roleplay · Multi-Genre

GPT

Isekai RPG

An isekai Custom GPT with a genuinely original world — deep NPCs, tactical combat, beast taming, and kingdom building, if you're willing to meta-game the drift.

Fantasy · Isekai · Roleplay

GEM

Realm & Companion RPG Prompt

A bare-bones copy-paste RPG prompt for Gemini — pick a realm, a character, and a companion, then choose from four options every turn. No systems beyond the choices themselves.

Fantasy · Multi-Genre · Roleplay

GPT

RPG GPT

A standard-issue ChatGPT RPG with nothing new under the hood — but one of the more disciplined ones about staying in character.

Fantasy · Multi-Genre · Roleplay

CLA

Solo D&D Starter Prompt

A one-line prompt that asks for a simple D&D-style solo adventure and gets exactly that — nothing more, nothing less.

Fantasy · Roleplay

GPT

Solo RPG Master

The most-played ChatGPT RPG — a multi-universe solo storyteller with standout characters and romance, if you can live with cliché worlds and stats that fade.

Roleplay · Multi-Genre · Romance

CLA

Valkyrie's Biggest Gig

A gritty solo cyberpunk RPG prompt for Claude where limb loss and cybernetic augmentation are the point — smooth and scalable, if a little too generous and a little too cliché.

Cyberpunk · Sci-Fi · Roleplay

GPT

Vantiel

A richly-lored ChatGPT RPG with serious promotional polish — an ambitious Custom GPT where the LLM is doing all the work the marketing promises an engine will.

Fantasy · Exploration · Roleplay

GPT

Star Freighter Drift

Run cargo, dodge customs, and keep the reactor from melting in a gritty space-trading AI RPG.

Sci-Fi · Trading · Survival

GPT

Fantasy · Kingdom Builder · Strategy

GEM

Eirathis Strider

A mature, Witcher-style open-world AI RPG for Gemini — dice-less combat, skill mastery, and a three-layered world of cosmic mystery.

Fantasy · Exploration · Mature

CLA

The Chronicler

A slow-burn, relationship-driven AI RPG for Claude where companions have their own goals, memories, and feelings — and trust is never guaranteed.
