Pathfinder-first. GM-native.

Your AI Game Master.
Always prepared,
never overwhelmed.

LoreWeaver generates NPCs, builds encounters, resolves rules, and keeps your campaign world alive — so you can focus on the story only a GM can tell.

The Problem

GM prep is a second job.

5–15
hours per week
spent on session prep by serious GMs
40+
rule subsystems
in Pathfinder alone, to memorize and apply
NPCs to invent
with names, motivations, secrets, voices
What LoreWeaver Does

Built for the table, not the office.

NPC Generator

Name, personality, motivation, voice, secret — fully realized characters with Golarion context. Ready in seconds, not hours.

Encounter Builder

Describe your party, pick a difficulty, and get a balanced encounter with tactical suggestions, terrain, and objectives.

Rules Arbiter

Ask any question about Pathfinder rules in plain language. LoreWeaver knows every book, every subsystem, every edge case.

World Continuity

Track your campaign — factions, NPCs, locations, plot threads. LoreWeaver remembers everything so you don't have to.

GM
"Generate a grizzled half-orc tavern keeper in Kintargo who secretly funds the Silver Crusade but doesn't want anyone to know why."
LoreWeaver

Gorath Stonefist runs the Rusty Halberd in Kintargo's Copper District. Deep scars across his muzzle and left ear tell stories he'll never tell. His voice is a low rumble that fills the room — he doesn't raise it, he doesn't need to.

Gorath serves an excellent lamb stew and never overcharges adventurers. He has a network of runners who carry coded messages to Silver Crusade operatives in the surrounding provinces. His money comes from an inheritance from a dead Chelaxian noble — one who was quietly assassinated for her sympathies.

He'll serve you well, but if pressed about the Crusade, he'll go cold and start pricing double.

The best GM moments happen at the table, not in the prep work. LoreWeaver handles the scaffolding so you can be present for the stories that matter.

Built for GMs. Built by someone who knows.
