Nomi alternative.
Nomi is a strong AI companion app that markets Human-Level Memory and takes privacy seriously. That privacy is also the catch: nobody outside your own chat can ever check how well its memory actually holds. If what you want is a living world with a memory you can audit, Creation OS is the closest alternative: the only AI RPG with a public record of one world played past turn 5,000, open for anyone to read. First world free, no card.
What Nomi is genuinely good at
Nomi's reputation is deserved, so start there. It is built for companionship: an emotionally attentive companion you talk to over months, with voice and group chats, and privacy treated as a first-class promise. Its own site markets Human-Level Memory across short, medium, and long term, and third-party reviews report it holding the majority of seeded facts in informal month-long tests, which is a strong showing for a companion app. (nomi.ai; third-party reviews, 2026.)
Notably, Nomi itself publishes no recall number at all. The company line is the phrase, not a figure. If your goal is a companion who feels present and keeps your confidences, that trade is fine, and Nomi's limited free tier lets you try it before paying.
The one honest reason to switch
Nomi's memory is private by design. For a companion, that is a feature. For a memory claim, it is a dead end: when the promise is “remembers like a human,” the only evidence you will ever hold is your own chat log, and nobody else can weigh in. There is nothing wrong with that bargain for companionship. A world makes a different kind of promise, one with books that have to balance: debts, alliances, quests, and grudges that must still add up thousands of turns after they were written down.
A promise about a world can be published and checked. So we did what a private companion app cannot: we let one ordinary campaign run past turn 5,000 and put the whole record where anyone can read it. Cast, factions, quests, and locations were all still on file at turn 5,011, sealed on 2026-06-26 with nothing dropped. Every world runs on the same record from its first turn; that campaign just shows how far it goes.

Try it before you take our word
A memory claim you cannot test is just a slogan, so do not take ours untested either. Open the record, pick any fact from early in the run, and follow it forward a few thousand turns. If it drifted, you will catch us. That is the deal a private companion app structurally cannot offer, and it is the entire reason we published: the burden of proof sits with us, not with you.
For the public proof itself, see the AI RPG that actually remembers. For how the whole field stacks up on this axis, see the best AI RPG with long-term memory. Then open a world of your own and hold it to the same standard.
Questions people ask
What is the best alternative to Nomi for an AI RPG?
For a living world rather than a private companion, Creation OS is the closest alternative. The practical difference is verifiability: Nomi's memory lives inside a chat only you can see, while Creation OS keeps a world's facts in a standing record and has published one campaign past turn 5,000 that anyone can open and check.
Open the record ▶Does Nomi have good long-term memory?
For a companion, yes. Nomi markets Human-Level Memory across short, medium, and long term, and third-party reviews report it holds the majority of seeded facts in informal month-long tests. Note that Nomi itself publishes no recall figure. Those are companion memories: one relationship, held privately. A campaign asks a different question, whether a whole world's facts still balance thousands of turns later, and whether anyone can verify that they do.
Nomi vs Creation OS: what is the real difference?
What gets remembered, and whether you can check it. Nomi remembers you, privately, which suits a companion. Creation OS remembers a world: debts, alliances, factions, and quests that must still add up much later, kept in a standing record on its servers. And it publishes the receipt: one campaign's full record past turn 5,000 is open for anyone to inspect.
Is Creation OS a companion app like Nomi?
No. Nomi is a companion app centered on one private relationship, with privacy as a core promise. Creation OS is a solo AI RPG and worldbuilding engine: a whole world with a Narrator, a cast, an economy, and quests. Want a confidant to talk to every day? Choose Nomi. Want a world that keeps score and can prove it? That is what Creation OS is for.
How does Creation OS prove its memory when Nomi only claims it?
By handing you the receipt. One ordinary Creation OS campaign ran to turn 5,011, then the full record was sealed and made public: cast, factions, quests, and locations still on file. You can page through it and hunt for a contradiction yourself. Nomi's memory is private and per user by design, so there is nothing comparable to open, which is exactly the gap Creation OS fills.
See the proof ▶Does Creation OS have a free option?
Yes. Your first world is free with no card. Nomi has a limited free tier, and third-party reviews list its paid plan around 16 dollars a month; Nomi does not publish pricing on its homepage. Prices on both move, so treat the figures as a July 2026 snapshot and check each site for the current number.
