As the rain eases, silver light spills from the sealed stacks. The librarian peels off her wet gloves and turns to you.

So you made it this far. I can't tell you where the key is. Not yet.
At the end of the aisle she points to, a set of footprints is still wet.
“Whose footprints are those?” I raise the lantern.↑

How it plays
Three steps to your first scene
Pick a world
Choose a Lore Pack from the library, or bring a world you made yourself.
Scene and role
Decide where you meet and who you are, then preview the opening before you start.
Write together
Type actions and lines and the characters answer. The world sharpens with every scene.
Built for long stories
A world that grows clearer with every scene
Lorerium keeps the details that usually scatter across a long roleplay connected to the flow of the story.
Memory
Long-term memory that returns
Search past conversations and key lore locally, then bring the right context back when it matters.
World
A living wiki
Keep people, places, and events in a wiki you can open again at any time.
Scene images
Character and place images prepared by the author appear with the scene.
Status panel
Follow time, place, and relationships right beside the chat.
PC + phone
Start on your PC, keep reading on your phone
Scan the invite QR from the desktop app and the story opens in your phone's browser. Your stories and AI sign-ins stay on the PC; only the screen comes to your phone.
- No install, just your phone's browser
- Only devices you approve on the PC
- Remembering a device is optional and revocable
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.
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.
A boundary you can understand
Cloud services for public Lore Packs never gain implicit access to local stories or your AI sign-ins.
Worlds you can carry forward
We aim for durable, portable formats instead of locking your stories and lore inside a single service.
