Everything in Mimir

One world. Many ways to understand it.

Mimir brings worldbuilding, visualisation, narrative planning, testing, consistency tools and collaboration into one connected workspace. Explore the tools individually, or follow the connections between them.

Mimir is in alpha. Availability labels below distinguish what exists now from work still being tested, developed or planned.

Build

Give every idea room to become a world.

Create and structure the world's information without turning creativity into form-filling.

Start with a name and a thought. Add fields, links, imagery and structure only when the world needs them.

CoreAvailable in alpha

Structured world entries

Create characters, species, cultures, places, factions, artefacts, events, languages, spells and other connected lore.

CoreAvailable in alpha

Flexible entry editors

Begin with as little as you know, then deepen an entry as the idea grows.

Apprentice+In development

Custom Schema Editor

Shape additional entry structures around the needs of a particular world.

CoreAvailable in alpha

Random generation

Generate a useful starting point from saved filters instead of staring at a blank page.

CoreAvailable in alpha

Assets & media

Keep images and supporting media connected to the entries that use them.

CoreAvailable in alpha

Hero images

Choose one reusable lead image for an entry, browser card or narrative beat.

Connect

Turn pages into a living system.

Reveal how people, places, cultures, histories and ideas depend on one another.

A world is defined by the relationships between its pieces, not merely by the existence of pages.

Relationships and backlinks screenshot slot
CoreAvailable in alpha

Relationships & inverse links

Model explicit connections in both directions rather than relying on prose alone.

CoreAvailable in alpha

Tags & linked navigation

Group ideas across entity types and follow connections without losing your place.

Visualise

See structures prose cannot hold.

Expose lineage, hierarchy, geography and chronology as visual systems.

Mimir does not flatten every connection into one generic graph. Each view is designed around the structure it needs to explain.

CoreIn development

Interactive maps

Connect locations and entries to geography rather than keeping place trapped in prose.

Write & Plan

Use the world while shaping what happens in it.

Develop stories, campaigns and interactive narratives beside the lore they depend on.

These are narrative and world-use tools inside Mimir's connected platform, not an attempt to turn it into a generic novel-writing app.

Story Arc editor

Structure an arc and connect its people, events and places back to canon.

Apprentice+In development

Arrange visual beats, branches and connected lore across a wider narrative canvas.

Spoiler-aware planning

Understand

Find answers. Catch problems. Keep canon grounded.

Retrieve the right information and distinguish structural certainty from language-based review.

Search, deterministic validation and AI review work together, but they do not pretend to be the same kind of evidence.

CoreAvailable in alpha

Deterministic validation

Catch known structural problems using rules whose results can be explained.

CoreAvailable in alpha

Surface likely naming clashes before they spread through a connected world.

Own & Protect

Local-first changes what you can rely on.

Keep work readable, recoverable, portable and under creator control.

Local-first is not a privacy slogan. It means ordinary files remain accessible, worlds are not locked behind a subscription and history can help recover mistakes.
