Dictation for Dungeon Masters and Session Prep
Session prep is a lot of writing: NPC voices, plot hooks, room descriptions, tavern menus, and the villain's monologue you will probably never use. Talking it out is faster than typing it, and modern Mac dictation can turn your rambling into clean notes without your campaign ever leaving your laptop.
Key takeaways
- Speaking out prep is faster and looser than typing, which suits improvised NPCs and lore.
- AI cleanup turns rambling spoken ideas into structured, readable notes automatically.
- A custom dictionary keeps fantasy names and homebrew terms spelled consistently.
- On-device dictation keeps campaign spoilers and secret twists private on your Mac.
Why dictation fits the way DMs actually work
Running a table is a spoken hobby. You already do NPC voices, describe rooms out loud, and think through encounters by talking to yourself on a walk. Typing all of that back up is the slow part. The gap between how fast you can improvise a gravelly dwarven innkeeper and how fast you can type his three paragraphs of backstory is where prep stalls.
Dictation closes that gap. Most people speak around three to four times faster than they type, so the raw idea lands on the page while it is still fresh. That matters more for creative work than for copying a form, because half-formed ideas evaporate if you have to stop and hunt for keys. If you have ever lost a great plot hook because you were mid-sentence in a Google Doc, voice capture is for you. The same logic applies far beyond the table: it is why voice input helps with everything from dictating emails on a Mac to long-form drafting.
From rambling voice to clean prep notes
The fear with dictation is that you end up with a wall of "um, so the, the guy, he has like a sword, no wait." That is where on-device AI cleanup earns its keep. It removes filler words, fixes punctuation and grammar, and can adapt the tone, so your spoken stream becomes something you can actually read at the table. Here is the kind of transformation you get.
Same idea, captured in one breath, but now it is scannable mid-game. You can dictate straight into your prep app of choice because good Mac dictation works system-wide: wherever your cursor sits, that is where the text lands. No copy and paste between a transcription window and Obsidian.
Handling fantasy names and homebrew jargon
Every campaign invents words. Your city of Vael'Thorn, the spell Mistgrasp, the NPC named Xylitha. Generic dictation guesses at these phonetically and spells them a different way every time. The fix is a custom dictionary: you teach the app your proper nouns once, and it locks them in. BlaBlaType supports a custom dictionary for exactly this, plus custom AI prompts so you can, for example, tell it to always format NPCs as a bolded name followed by traits.
It also handles 90+ languages with optional translate-as-you-speak, which is a quiet superpower if your setting leans on real-world languages for flavor or if you play at a multilingual table.

Dictation vs typing vs built-in tools for prep
Here is how the common ways to capture session prep stack up for a dungeon master.
| Approach | Speed | Handles homebrew names | Cleans up rambling | Private by default |
|---|---|---|---|---|
| Typing it all | Slow | Yes | No | Yes |
| Apple Dictation | Fast | Guesses | No | Mixed |
| Cloud voice app | Fast | Yes | Yes | Uploads audio |
| BlaBlaType | Fast | Custom dictionary | Yes | On-device |
Apple's built-in macOS Dictation is free and fine for a quick line, but it does not clean up your speech or learn your homebrew vocabulary. Cloud apps clean up nicely but send your audio off your Mac, which is a real consideration when your notes contain the twist ending your players must never see.

Who benefits most
Dictation is not only for the DM. Here is where it earns a spot for different people at and around the table.
The prep-heavy DM
Talks out NPCs and lore on a walk, then arrives home to notes already written and tidied.
The worldbuilder
Drafts gazetteers and faction histories by voice, keeping every invented name spelled the same way.
The privacy-first table
Keeps spoilers, twists and player notes fully on-device, never uploaded to a third-party server.
Voice capture also lowers the barrier for anyone who finds a blank document intimidating, which is one reason it overlaps so well with voice-to-text for ADHD: momentum matters more than perfect first-draft prose.
Prep your next session by talking
Dictate NPCs, lore and encounters straight into your notes app. AI cleanup included, every word stays on your Mac. No card needed for the trial.
Download for macOSA simple prep workflow to try
You do not need to overhaul your process. Start small: pick one prep task you dread typing, like reading out a dungeon's room-by-room description, and dictate it instead. Set a global shortcut so a single key starts and stops recording, open your notes app, and talk. Let the AI cleanup pass handle the punctuation. Over a few sessions you will find the tasks where voice wins big (improvised dialogue, lore dumps, recap summaries) and the ones where typing is still better (stat blocks, tables). For pricing and the on-device details, the plans page lays it out. If you want to compare tools first, the Mac dictation roundup is the place to start.

Frequently asked questions
Is dictation actually faster for session prep?
For most dungeon masters, yes. Most people speak around three to four times faster than they type, so talking out an NPC voice, a plot hook or a room description usually gets the raw idea down quicker than typing it, and AI cleanup handles the punctuation afterward.
Can dictation handle fantasy names and homebrew jargon?
Yes, if the app has a custom dictionary. BlaBlaType lets you add character names, place names and homebrew terms so words like a made-up city or a spell name are spelled consistently instead of guessed phonetically.
Will my campaign notes stay private?
With on-device dictation, yes. BlaBlaType runs speech recognition and AI cleanup entirely on your Mac, so your campaign notes, spoilers and secret plot twists never leave the device or get uploaded to a server.
Does dictation work inside my note-taking app?
Yes. BlaBlaType types wherever your cursor is, so it works system-wide in Obsidian, Notion, Apple Notes, a Google Doc or a virtual tabletop, without copy and paste between windows.
Can I dictate at the table during a live session?
You can. A global shortcut starts and stops dictation, so you can capture an improvised NPC or a rules ruling mid-game and clean it up later, all without uploading audio from your table.
