Private records stay on your computer
Chats, character images, wiki pages, and search indexes live in the desktop app's local data area by default.
Local-first roleplay archive
Give every world you create
a memory that lasts.
Lorerium is an AI roleplay desktop app that weaves characters, lore, and the memory of every scene into one place. Your private stories stay on your computer by default.

The night the stars vanished
The final observation ended at midnight. Estelle could still feel a trace of warmth on the brass telescope.

Local by default
Your story should always belong to you.
The cloud can add convenience, but it should never take ownership of the private worlds you create.
A boundary you can understand
Cloud services for public game packs never gain implicit access to local stories or your ChatGPT credentials.
Worlds you can carry forward
We aim for durable, portable formats instead of locking your stories and lore inside a single service.
Built for long stories
A world that grows clearer with every scene
Lorerium reconnects the details that usually scatter across a long-running roleplay without pulling you out of the story.
01 · Conversation
Chat shaped around the scene
Manage single or multiple roles, opening scenes, and prose rules together so each story keeps its voice.
02 · Memory
Long-term memory that returns
Search past conversations and key lore locally, then reconnect the right context when it matters.
03 · World
A living wiki and image library
Organize people, places, and events in a wiki, then bring character image assets into the right scene.
