About this game

Mythx is an AI fantasy dungeon adventure game. Your AI game master writes the world around you, draws every scene in the art style you pick, and fills it with characters who notice you and remember you. Speak, act, or continue — and shape a story no one has ever played before. No two adventures are ever the same.

Create Your Character
Begin with the character creator: choose your gender, enter your name, and pick how your story starts. Wake up alone in a mysterious world — a true isekai opening — begin beside a companion, or enter in the middle of a fight. Every beginning sends your fantasy adventure down a different path.

Explore an Open World of Realms
Mythx is built around realms, places, and fantasy locations. Use the world button to view the realms around you and the places inside each one. Your adventure starts in one location, but the story can travel through magical lands, dark fantasy realms, ancient ruins, dungeon crawls, dangerous roads, and strange villages — an open world dungeon adventure created through AI storytelling.

Illustrated Scenes in Your Art Style
Every scene pairs an image with AI-written text that tells you what is happening. Mythx blends visual novel (VN) presentation, text adventure choices, and AI story generator gameplay — and you choose how your story is drawn: Anime, Manga, Webtoon, Dark Fantasy, Graphic Novel, Watercolor, Pixel Art, and more. A light novel you play, in the art you love.

Meet AI NPC Characters Nearby
The world is not empty. Every place shows the AI NPC characters present right now — each with a name and a live activity: waiting, watching, fighting, exploring, resting, talking. Walk up and speak to any of them inside the story — ask questions, trade rumors, persuade, or provoke. They remember what you say, and what you do can change what they do next. It makes every place feel more alive than a static text RPG or a simple story generator.

Speak, Act, or Continue
Three simple ways to play:

• Speak when you want to talk to AI NPCs — roleplay, ask questions, persuade, joke, or confess
• Act when you want to change the scene — attack, run, search, protect, hide, travel, or use an item
• Continue when you want your AI dungeon game master to write the next scene and move the adventure forward

Every choice can affect the next moment. Your words, actions, and decisions shape the AI stories unfolding around you.

Ratings and reviews

Really fun AI RPG with a super cool setup! I love picking my character and starting scene, and the mix of text and images makes the story come alive. Being able to see nearby NPCs and what they’re doing is an awesome touch that makes the world feel so real.

Can't even start the app. It asks me to sign in with Google and when I do i just get an error code.

Mythx AI is a fun story RPG with a lot of potential. I like picking a starting setup and seeing where the AI takes it. The images and descriptions work well together, and the world/character buttons make it easy to follow what’s happening around you.
