Worldbuilding with a continuity engine: generate lore fast, keep it coherent—without retcons
Worldbuilding is one of the most rewarding—and challenging—aspects of creative work. Whether you're writing a novel, designing a game, or running a tabletop campaign, creating a rich, consistent fictional universe requires countless hours of planning, note-taking, and revision.
Urdr is built to help creators focus on what matters: telling great stories. We combine structured data (a real world bible, not a wiki) with AI-assisted workflows to support ideation, reduce continuity drift, and surface contradictions early—before they become plot holes or production bugs.
Think of it as Lore CI: your canon lives as entities and relationships you can search, evolve, and export.
Built for creators who care about coherence. Every feature starts with the question: does this help you keep canon consistent?
We focus on pragmatic, efficient workflows and clear data boundaries so you can build worlds without surprises.
Multi-provider AI ensures your worldbuilding never stops. When one service has issues, we automatically fail over.
We believe in being honest about our technology, pricing, and limitations. No black boxes, no surprises.
Urdr runs on a modern, resilient stack designed for speed and reliability. We use a multi-provider AI strategy to improve availability, and we keep the core of your world stored as structured data so it remains searchable and consistent over time.
Our multi-provider AI strategy (GitHub Models → Groq → Gemini) ensures high availability. If one service experiences downtime, we automatically fall back to the next provider—your worldbuilding never stops.
Urdr is built by a small team that cares deeply about craft: coherent worlds, consistent rules, and tooling that respects your time.
If you're using Urdr for game dev, TTRPG campaigns, or a novel series, our goal is the same: help you ship stories and worlds without continuity debt.
