Make your characters feel real.

Museris is the best local AI roleplay app for people who want more from their stories.

Make a character. Give them a personality, an avatar, a first message, lore, bad decisions, weird secrets—whatever makes them them. Pick a model, start a scene, and see where it goes.

Want a vampire roommate? A suspiciously charming space pirate? Your OCs finally getting to hang out? A whole fantasy kingdom with way too much political drama? Museris has you.

The magic stuff

• Characters with actual vibes. Create and save characters with descriptions, greetings, and avatars.
• Bring your favorites. Import Tavern PNG cards and Museris character packages.
• Worldbuilding that sticks. Build lorebooks for worlds, places, factions, relationships, rules, and deep-cut backstory.
• Set the scene. Combine characters, lore, and scene prompts into roleplay chats.
• Fix the timeline. Edit messages, regenerate replies, and swipe through alternates when the first response is not hitting.
• Get weird with it. Customize prompt templates when you want to tune every little thing.
• Your model, your rules. Connect local servers, OpenAI-compatible APIs, or Museris Hub.
• Your library stays yours. Museris is local-first. Your characters and chats live on your machine and can be exported whenever you want.

For the people with 40 OCs and one extremely specific vision

Museris is built for the people with six half-finished worlds, a notes app full of character lore, and one scene they have been replaying in their head for three days.

It is fast, flexible, local-first, and made to get out of the way once the story starts.

Make somebody unforgettable.

Before you begin

Museris needs a generation provider or local model server for AI responses. Bring your own OpenAI-compatible setup, run locally, or connect through Museris Hub.
