Mimir

A Windows app for game masters. It's been at my own table for about a year.

Live D&D transcription that pulls the right card from an Obsidian vault as names come up. OneNote, Evernote and Notion are next.

It still finds the right card when someone mispronounces a name.

Mimir listens at the table on your own PC and shows the matching card from the GM's Obsidian notes, or from the free SRD 5.2.1 rules, the moment someone names a character, place, spell or monster. Its Scribe feature turns a recorded session into a speaker-labeled transcript and a recap note in the vault. Speech is transcribed on that machine, so the table's voices stay in the room.

Why I made this

I run a few tabletop games and keep way too many notes in Obsidian. I wanted the right note to just show up when somebody said a name, without me digging for it. Mimir has been running at my own table for about a year.

What it does

  • Say a name, get the card. Pulled from the Obsidian vault and the free SRD 5.2.1 rules. Phonetic matching copes with the invented names speech recognition always mangles, and there's no generative AI involved.
  • Scribe writes up the session (Pro). Give it a recording (one file per player, a zip or one mixed file) and it writes a speaker-labeled transcript and a recap note into the vault. It runs on any CPU, and a re-run never overwrites a note that's been edited.
  • Audio stays on the machine. It isn't saved unless recording is turned on. One command lists everything Mimir keeps, and another deletes it.
  • The AI part is optional. Off by default. Use your own API key or a free local model, with per-session and monthly spend caps on from the start.
  • Online games or a real table. An always-on-top overlay for the virtual tabletop, plus a page for a tablet or a second monitor.

What it doesn't do

  • It doesn't run the game or write it; it finds what's already written.
  • AI never plays the characters, even when it's turned on.
  • No macOS or Linux version yet, only Windows.
  • One mic for a whole room makes speaker labels less reliable.
  • It doesn't get the table's consent; the GM has to.
A Mimir card for Maelis Varrow, harbor-master of Hollowmere, with folded sections for appearance, voice and pronunciation, secrets and related notes.
The line under the card shows what it heard: “Malice Farrow”. This is Mimir's demo campaign, so every name in it is made up.

Who it's for

Game masters who keep their notes in Obsidian and run games in person or online.

A few more screenshots

A Scribe recap note for the demo's Session 3: every name from the notes that came up, how many times and who said it first, and how long each of the four players talked.
After the game, Scribe writes a recap like this into the vault, with no AI involved. Same made-up session.

Questions

Do my players need to agree?
Yes. Transcribing people is recording them, and some places require everyone's consent. Mimir prints a plain-language notice for the group that describes what the current settings actually do. Any track can be muted, and Mimir can be turned off for a session.
Is there a session limit?
No. Scribe runs on your own PC, so there's no per-session fee or monthly cap.

What it keeps, and where

Mimir runs on your computer and turns speech into text there, so the table's voices stay in the room. Nothing about the game leaves that computer except through a feature that says so and has been turned on.

Goes online only for: AI answers and recaps (off until you turn it on); Discord voice feature (off until you turn it on); Model downloads (on first use).

Mimir's window during its built-in demo: an open card for Maelis Varrow, harbor-master of Hollowmere, found after speech recognition heard Malice Farrow, with smaller cards for two places below it and the live transcript at the bottom.
Someone says a name and its card comes up, even when speech recognition hears “Malice Farrow”. This is Mimir's demo, a sample session played from a script, so every name in it is made up.
