§ The principles
What it does. What it refuses.
Five things mimicdm does that nothing else does. Six it refuses to do, even when asked. Together: the spine of the product, written down so we can be held to it.

It speaks. You speak. Nobody is reading a chat log at 10 p.m.
Text DMs make every turn feel like group email. mimicdm narrates aloud, in character, with the pacing of a human running a table. Each of the nine narrators has its own cadence — one clipped, one ceremonial, one that pauses in the wrong places on purpose.
Players speak back. Push-to-talk per character, like a ship's intercom; whisper.cpp runs the transcription locally so your voice does not leave the host's machine when you're running a local model. Voice is the default. Typing is always available, because sometimes the kitchen is loud.
→ press-to-talk · whisper.cpp local · nine Piper personas
A DM that does not flinch at the scene you planned.
Ask a mainstream assistant to run the Hag's bargain, the betrayal at the monastery, the long interrogation in the salt mine — it refuses, softens, breaks character, lectures you about fiction. That is not a DM. That is a corporate policy document with a voice.
Sessions support a safety vocabulary — lines, veils, the standard TTRPG tools — so the table can dial the content it wants. The goal is not shock. The goal is a DM that treats the players like adults who planned a real campaign.

Saturday plays, even when half the party is at a wedding.
The hardest thing about running a long campaign is not the rules. It is attendance. mimicdm treats absence as a feature, not a failure. When a player cannot make the session, their character keeps playing — run as a cautious, faithful NPC by the DM itself.
Marcus's rogue does not rob the party blind. She does not suddenly become a different character. She scouts carefully, keeps her mouth shut in court, and hands back the spotlight when Marcus logs in on Tuesday. The story keeps moving, without the thing that kills most campaigns.

Your campaign lives on a hard drive, not someone else's cloud.
mimicdm is built to run on the host's machine. Saves, transcripts, audio, character sheets — all on local disk. Point it at LM Studio and the model runs on your own GPU; nothing leaves the room. This is not a marketing flourish; it is how the app is architected.
If you'd rather not run a model yourself, the app speaks to any OpenAI-compatible endpoint — OpenRouter being the obvious one. That costs cents per session and keeps nothing on a mimicdm server, because there is no mimicdm server in the loop.
→ LM Studio · OpenRouter · zero server-side storage
Your friends join from a browser. No download. No account.
The host runs the app. Friends join a hosted session from whatever device they happen to have — phone on the bus, laptop on the couch, tablet on the kitchen counter. Push-to-talk per character. Live transcript. Shared dice.
The web client is in active build and opens to the waitlist first. An iOS companion for players is in the queue behind it. Hosts stay on the desktop app, where the heavy work runs.

A SHORT MANIFESTO
Things we refuse to do.
No. 01
No slot machines.
No infinite-scroll loot. No streak counters. No dopamine on a schedule. The only reward we offer is what happens next in the story.
No. 02
No rolling for you.
The dice are yours. The DM can call a check; the DM cannot resolve it in secret. If a result is bad, the result is bad.
No. 03
No rainbow UI.
One brass. One ember. Cream paper or obsidian glass. The ornament is in the typography, not in the colors.
No. 04
No emoji.
The system has thousands of years of typographic ornament behind it. We can find a pilcrow before we reach for ✨.
No. 05
No fast travel.
Three days on the road takes three exchanges, not three taps. Time has weight. Distance has weight. Nothing important should be free.
No. 06
No mascots.
The DM is a voice and a hand. Not a face, not a name, not a personality with quirks. The character is yours. The world is the world’s.
