Chub AI is an adults-only community where users publish AI character cards and run uncensored roleplay chats, supported by lorebooks, presets and an OpenAI-compatible inference API. It is aimed at hobbyist writers and roleplayers who want minimal content filtering, and it is not suitable for workplace or general-audience use.

Chub AI is a community platform for AI character cards and roleplay chat. Loading the site gives very little away at first — the homepage renders a single headline: "GenAI for everyone." — but the product behind that slogan is specific and well defined. Users create characters, publish them publicly, and hold extended conversations with them through large language models.
Two facts should be established before anything else, because they determine whether this tool is relevant to you at all.
First, this is an adults-only service. The terms of service state without qualification: "The Services are intended for users who are at least 18 years old. Persons under the age of 18 are not permitted to use or register for the Services." That is not a formality attached to a general-purpose product; it reflects what the platform actually hosts.
Second, the platform is explicitly uncensored, and says so in its own documentation rather than leaving it to be inferred: "Chub is uncensored. We do not restrict in any meaningful capacity the variety of characters that are allowed to be posted on the platform" nor the type of interactions permitted with them. Content moderation is limited essentially to material that is illegal to host. Anyone evaluating this tool should understand that this positioning is the product's central design decision, not an incidental detail.
On identity, the operator names itself in the terms, stating that for the purposes of that document "we" refers to Chub (AKA CharHub). The dual naming is visible throughout the product — the homepage links to a legacy site at characterhub.org, and the CharHubAI organisation on GitHub was created in April 2023 and lists chub.ai as its homepage. That gives a reasonably clear picture of a project that started as Character Hub around 2022–2023 and became Chub. Notably, no corporate legal entity, registered address or jurisdiction is published anywhere in the terms, which is unusual and worth flagging.
On scale, the site's own metadata invites users to "Join our 5M+ players for free". This is a vendor self-report with no independent audit, and it should be read as marketing rather than a measured figure.
The public search page organises everything into six content types: Characters, Lorebooks, Presets, Stages, People and Tags. Characters are the primary unit — portable definitions of a persona, its background and its speaking style. Because they are community-published and browsable without an account, the library itself is the main draw rather than any single proprietary model.
Lorebooks store background facts that get injected into context when relevant, which is the standard solution to the fundamental limitation of long roleplay: models forget. For anyone running a long-running scenario with a consistent setting, this matters more than raw model quality.
Presets capture reusable generation settings, so a user can save a configuration that produces the tone they want rather than retuning parameters each session. Stages are a more advanced construct for scripted or interactive scenarios, with the documentation covering both the use and the development of them.
This is architecturally the most important feature. Chub is a front end and aggregation layer rather than a model lab. Its documentation confirms it "supports numerous APIs such as OpenAI (ChatGPT) or Anthropic (Claude), features such as chat trees, image generation, exporting/importing chats" from other services. Users can connect their own provider keys or use Chub's hosted models. Chat trees deserve a specific mention: they let a conversation branch, so an unsatisfying reply can be regenerated down a different path without discarding the history.
The subscription includes API access, and the scope is broad: "The API can be used anywhere that supports OpenAI's APIs." In practice this means the subscription can power third-party front ends such as SillyTavern rather than locking users into Chub's own interface.
Collaborative fiction and interactive storytelling is the main use. Writers use characters plus lorebooks to sustain a consistent world across long sessions, in a way that a plain chat assistant does not support well.
Character design and sharing is a use in itself. A significant share of activity is creating and refining character definitions for others to download, closer to a creative publishing community than to a chat product.
Playing with model behaviour is a third. Because presets, prompts and providers are all user-controllable, the platform functions as a testbed for prompt engineering with far more exposed settings than consumer chat apps offer.
Using it as a subscription API gateway is a fourth, distinct use. Since the endpoint is OpenAI-compatible and unmetered for a single user, some subscribers treat it primarily as a flat-rate inference source for other clients.
Adult roleplay is, candidly, a major use case and the reason many users choose this platform over filtered alternatives. Stating that plainly is more useful than implying otherwise.
Conversely, this is not a tool for workplace deployment, customer-facing chatbots, or any context where content unpredictability carries reputational risk.
Treat the model as the main variable. Most complaints about output quality in this category trace back to the underlying model and its context limit, not to the character card. Changing model is usually more effective than rewriting a persona.
Use lorebooks instead of overloading the character definition. Stuffing every detail into the card consumes context permanently, whereas lorebook entries are injected only when relevant — a more efficient use of a limited window.
Understand the licence before publishing. Publishing a character grants a broad licence, discussed below, and it does not fully unwind on deletion. Anything you intend to commercialise elsewhere should not be posted publicly here.
Keep private work private. The privacy terms for private content are meaningfully stronger than for public content, and that distinction is under your control.
Budget for the payment method. Since subscriptions are crypto-only, factor in the practical friction of acquiring and sending cryptocurrency, and remember refunds are not offered by default.
Export regularly. Long roleplay sessions represent real creative investment; do not leave the only copy on someone else's server.
Assume anything public is permanent. Even setting aside the licence terms, published character cards are downloadable by design and propagate beyond the platform.
The core audience is adult hobbyists in AI roleplay and interactive fiction — people who want granular control over prompts, models and personas, and who accept the tradeoffs that come with an uncensored community platform.
It also suits technically inclined users who want a flat-rate, OpenAI-compatible inference endpoint for use in third-party clients.
Creative writers exploring character-driven fiction may find value, provided they are comfortable with the surrounding content environment.
It is unsuitable for anyone under 18, for workplace or educational deployment, for businesses building customer-facing products, for users who need guaranteed content safety, and for anyone unwilling or unable to pay in cryptocurrency. Those needs are better served by mainstream assistants or by moderated character-chat platforms.
Chub AI is delivered as a browser-based web application. It is built as a client-side rendered single-page application, which has one practical consequence worth knowing: the raw HTML contains almost no content, so the site renders only with JavaScript enabled and may behave poorly on very constrained connections or in text-only browsers.
Support and community channels are unusually distributed for a product of this size, spanning documentation, a blog, a GitHub organisation, a Reddit community, a Bluesky account and a system status page — all linked directly from the site footer, along with the real legal paths at /tos and /privacy.
Beyond the official interface, the OpenAI-compatible API means the service can be consumed through third-party roleplay front ends, which is a meaningful part of how subscribers actually use it. No official native mobile or desktop application is published.
Pricing is refreshingly simple: a single tier at $20/month, advertising unlimited access to all LLMs, including Soji 1.6T 60K, plus unlimited voice and multimedia generation and early access to new models.
Free access exists but is limited. The subscription page explains: "One-time free trial credits amounting to a few dozen messages are sent out to new users regularly." Browsing the library and using your own API keys remain free — a genuinely important point, since a user with their own provider key can use much of the platform without ever subscribing.
"Unlimited" is defined honestly rather than left vague. It means unlimited for one person, comparable to a streaming account: concurrent requests from the same account return a 429 error, and conspicuous key sharing may trigger restrictions.
Payment is cryptocurrency only, and the reasoning is stated outright: "The primary sources of censorship pressure for most websites are credit card companies and payment processors." Avoiding them is a deliberate strategy to remain free of content restrictions imposed by financial intermediaries. For prospective subscribers this is a real access barrier and should be weighed accordingly.
Refunds are restrictive. The terms state plainly: "Chub does not offer refunds unless explicitly granted by the Company." Cancelling stops future billing and access ends when the paid period expires.
SillyTavern is the closest comparison in spirit — a self-hosted, open front end offering even more control, at the cost of setting it up yourself. Notably it pairs well with, rather than replaces, a Chub subscription, since Chub's API can serve as its backend.
Character.AI is the mainstream counterpart: far more polished and accessible, with strong content filtering that is precisely what Chub's users are avoiding.
Janitor AI and similar platforms occupy adjacent territory with comparable content policies and varying model options.
Running local models with a front end is the alternative for users whose priority is privacy or cost control, requiring capable hardware but eliminating both subscription fees and third-party data handling.
For non-roleplay uses, mainstream assistants are simply better products, and users considering Chub for general tasks are likely evaluating the wrong tool.
The content licence for public uploads is broad and deserves careful reading. Publishing content grants Chub "a non-exclusive, royalty-free, perpetual, irrevocable worldwide license (with sublicense and assignment rights)" to use, display, adapt and distribute it. Deletion terminates the licence going forward but does not revoke it for anything already copied or sublicensed. Public content also grants every other user a perpetual licence to reuse it.
The terms may change retroactively, which is an unusual provision: "All changes made to these terms are retroactive and apply to any and all users, content and communications, overriding any previously agreed upon terms." Combined with the absence of any notice requirement, this places users in a weak contractual position.
Liability is tightly capped. Downloaded user content is licensed for personal, non-commercial use only, no non-infringement warranty is given, and total liability is "LIMITED TO THE LESSER OF THE AMOUNT PAID, IF ANY, BY YOU TO US DURING THE SIX (6) MONTH PERIOD PRIOR TO ANY CAUSE OF ACTION ARISING OR $50.00 USD".
Content risk is inherent to the model. On a platform that removes only illegal material, users will encounter material they find objectionable. The prohibitions that do exist are firm — content sexualising anyone who is or appears to be under 18 is "strictly prohibited. Any attempt to rules lawyer or play games with this will result in account termination" — but everything short of the legal line is permitted by design.
Independent verification is essentially unavailable. This product has no Product Hunt listing (the URL returns 404), no G2, Capterra or Trustpilot profile with a usable rating, and no coverage from any major technology publication that could be located. Almost all "reviews" in search results are published by companies selling competing products or by SEO aggregators, and several lookalike domains exist. Nothing from those sources is relied upon here; every factual claim in this entry comes from the official site, the official documentation, or the official GitHub organisation. The absence of independent scrutiny is itself a consideration for anyone assessing the platform's reliability.
Corporate opacity is another. No legal entity, company address or governing jurisdiction appears in the terms of service — unusual even among small platforms, and relevant to anyone weighing recourse in a dispute.
Finally, the crypto-only payment requirement and the SPA architecture both impose practical access constraints unrelated to content.
The privacy posture is genuinely stronger than the platform's informal presentation might suggest, particularly for private content — though the policy document itself is short and light on detail.
The stated collection scope is minimal: "We do not disclose any user data to third parties without the explicit consent of the user. We only collect personal information that is necessary for the functioning of our site, such as usernames." Registration requires an email, used sparingly for password recovery and subscriptions.
The strongest commitment concerns private content. Private characters and chats "will not ever be distributed to a third party, unencrypted, used for training an AI model, or any other purpose beyond providing the Services", with users retaining all intellectual property rights and granting Chub none. An explicit no-training commitment is more than many larger platforms offer.
API usage goes further still: "none of the content of the inputs or the outputs of queries made to the inference endpoints at *.chub.ai are at any point logged or stored." Only metadata — an identifier, user ID, timestamp, input and output lengths, model used and duration — is retained. For privacy-sensitive users this is a meaningful design choice.
The critical distinction is public versus private. Everything above applies to private content. Public content carries the sweeping perpetual licence described earlier. Users control which regime applies, and should choose deliberately.
Two honest caveats. The privacy policy does not enumerate GDPR or CCPA rights, name a data controller entity, or state retention periods — reported here as absences in the published text rather than as claims about actual practice. And if you connect your own third-party API key, your conversations are processed by that provider under its terms, not Chub's, which is easy to overlook.
Partly. Browsing the character library requires no account, and connecting your own OpenAI or Anthropic API key lets you use much of the platform without subscribing — though you then pay that provider directly. New users also receive one-time trial credits amounting to a few dozen messages. Unlimited hosted model access requires the $20/month subscription.
Yes, and it is absolute. The terms state the services are intended for users at least 18 years old and that people under 18 are not permitted to use or register for them. The platform hosts adult content by design, so this is a substantive restriction rather than boilerplate.
Within legal limits, yes. The documentation states the platform does not meaningfully restrict the characters that may be posted or the interactions users may have. Moderation focuses on illegal material. There are firm exceptions: any content sexualising anyone who is or appears to be under 18 is strictly prohibited and results in account termination, as is illegal imagery and revenge porn.
The subscription is $20 per month for unlimited single-user access to all models, voice and multimedia generation. Payment is cryptocurrency only. The stated reason is that credit card companies and payment processors are the main source of censorship pressure on websites, so avoiding them keeps the platform free of that pressure.
Generally no. The terms state that Chub does not offer refunds unless explicitly granted by the company. Cancelling prevents future charges, and access continues until the current period expires.
Both your own and theirs. The platform supports third-party APIs including OpenAI and Anthropic, and subscribers get hosted access to all available models including the in-house Soji 1.6T 60K. Subscription API access is OpenAI-compatible and usable in any client that supports that interface.
For private content, the terms explicitly say no — private characters and chats will never be distributed to third parties or used to train an AI model. For direct API use, inputs and outputs are not logged or stored at all, only metadata. Note that if you connect your own third-party API key, that provider's policies govern your conversations, not Chub's.
You grant a perpetual, irrevocable, worldwide, sublicensable licence to Chub, and every other user receives a perpetual licence to use and adapt your public content. Deleting it ends the licence going forward but does not revoke copies already sublicensed. Do not publish anything you intend to control or commercialise elsewhere.
No. It is an adults-only platform that intentionally hosts unfiltered content, including sexual material. It is unsuitable for workplaces, shared devices, educational settings, and any customer-facing application.
Because there essentially are none. There is no Product Hunt listing, no rated profile on G2, Capterra or Trustpilot, and no located coverage from a major technology publication. Most "review" pages are written by competitors selling alternative products or are SEO aggregators, and several lookalike domains exist. Verify anything you read against the official site, documentation and GitHub organisation.
