We build two products: Argus, server-side anti-cheat for Minecraft servers, and NarrativAI, a writing tool that keeps long stories consistent. Both take on the repetitive work; the judgment and the final call stay with the people using them.

We build.
We write the software ourselves: the runtime, the trust model, and the unglamorous parts nobody demos.
We invest.
Capital and operating time for software that pays attention to the people using it.
We operate.
We stay after launch, close to the writers, guests, and server owners who rely on what we ship.
Every product holds to it: help people do better work, show the reasoning, and leave the decision with a person. Each stage badge says exactly where a product is today, and the Studio Ledger records how it got there.

Gaming Infrastructure
Tools for the people who run game servers: anti-cheat that hands moderators evidence, and performance tooling that shows its work.
- ArgusFlagshipv1.0 in development
Every finding comes with the evidence behind it. Your moderators make the call.
Server-side behavioural anti-cheat for Minecraft Java & Bedrock. Checks that can’t judge a player fairly are switched off rather than guessed at: mouse-based checks for Bedrock touch and controller players, and any check the server’s capture source can’t properly feed, with the reason logged.

Performance-debt auditing built into the Minecraft server.
The Minecraft-integrated successor to our CullAI prototype, designed alongside Argus. In design; nothing to install yet.

Affective Narrative
Co-writing tools for long-form fiction that stay visible about exactly what the AI is doing.
- NarrativAIClosed beta
For writers whose original characters outlive a single story.
The OC Vault learns your cast from what you’ve already written and flags when chapter 30 contradicts chapter 3. Muse, the co-writer, always shows which state it’s in — listening, drafting, or safety checking — so you know who wrote what.

Ambient Hospitality
Guest-facing intelligence that asks your team when it doesn’t know, then remembers the answer.
- OperaHousePrototype
When Alfred doesn’t know, it asks your team — and never has to ask that question again.
A guest-messaging layer for hospitality teams. Guests get the right answer or a person, never a confident guess, and every answer your staff gives becomes a searchable record instead of a lost chat thread.

How to choose an anti-cheat for your Minecraft server
There’s no single best anti-cheat. The questions that narrow it down for your server, and a simple way to shortlist without banning your regulars.
Argus · GuideWhy Minecraft anti-cheats flag honest players, and how to cut false bans
Most false bans happen when an honest player’s game looks like cheating from the server’s side. The usual causes, and what to do about each.
Argus · GuideAnti-cheat on a Geyser crossplay server: what to know about Bedrock players
Geyser brings phone and console players to your Java server, and makes anti-cheat harder. What to check before you trust one with Bedrock players.
CullMC · GuideHow to find what’s causing lag on your Minecraft server

GuideHow to keep OC and fanfiction continuity consistent across a long story
Continuity drift isn't a discipline problem — it's what happens to every long story with a real cast. Practical ways to actually stay on top of it.
NarrativAI · Dev LogNarrativAI vs. Sudowrite, Squibler & the rest: what's actually different
A fair, feature-by-feature look at how the OC Vault and Muse compare to the AI writing tools people usually put alongside NarrativAI.
What is OperaHouse Ventures?
An AI venture studio that builds and invests in emotionally intelligent AI that empowers people, never replaces them. Our products take on repetitive work, show their reasoning, and leave the judgment and the final call to people. We operate each product directly, including Argus, CullMC, NarrativAI, and OperaHouse.
What is NarrativAI?
An AI co-writer for original-character and long-form fiction, pairing Muse — a co-writer that always shows which state it's in — with the OC Vault, a continuity engine that catches contradictions across chapters as you write.
What is the OC Vault?
A continuity engine that builds itself passively as you write, reading your drafts and extracting facts about your characters, world, and timeline without you maintaining a separate story bible.
Who is Muse?
NarrativAI's AI co-writer. Unlike tools that generate silently, Muse always shows which state it's in — Listening, Drafting, and Safety Checking are live in the beta today, with Suggesting and Resting still on the way.
Is NarrativAI free to try?
Yes. NarrativAI is in closed beta with a free tier (~1,750 words/day, then $2.99 per 5,000-word Usage Credits top-up). Premium is $5.99 every 30 days with no daily cap, cancel anytime, and starts with a 7-day free trial, no card required. The first 100 members can also take a one-time $99 Founding Member pass for lifetime Premium access, a 50,000-word Usage Credits grant, and a permanent badge.
