AI-powered campaign intelligence for tabletop RPGs

Your campaign, remembered.
Your next session, ready.

Loreweaver helps you run richer tabletop worlds—whether you want a Co-GM beside you or a full GM for solo play.

It grounds every session in your adventure, your campaign history, and the choices already made.

Get startedSee how it works

Built for campaigns that deserve to be remembered.

Choose your seat

A capable partner at the table—or behind the screen.

Loreweaver adapts to the way you want to play while keeping the same campaign history intact.

Co-GM

You run the table. Loreweaver keeps the threads together.

  • Ask questions about characters, locations, quests, and prior sessions
  • Generate connected NPCs, settlements, rumors, shops, and encounters
  • Surface unresolved clues, promises, threats, and story threads
  • Review suggested changes before they become canon
Explore Co-GM mode

Solo Play

Step into the world. Loreweaver runs the adventure.

  • Explore source-grounded scenes
  • Talk with characters who have their own knowledge and agendas
  • Resolve checks, discoveries, and encounters
  • Return to a world that remembers your choices
Explore Solo Play

Designed for lasting worlds

More than an AI storyteller

Grounded in your world

Loreweaver draws from imported adventures, campaign records, session history, and established canon—not an empty chat window.

Built for continuity

NPCs, locations, quests, clues, relationships, and consequences remain connected across scenes and sessions.

Canon stays under your control

Creative ideas remain visible suggestions until the GM chooses to keep them.
