Chub AI - official info, login and pricing
The real Chub AI is at chub.ai, and the roleplay chat is at venus.chub.ai. It came from the 2024 merger of Venus AI and CharacterHub, hosts 60,000+ characters, and lets you run almost any model. There is no Chub app on the app stores anymore, so the browser is the way in. This page is a pointer, not the product. Everything below points you to the real Chub AI and skips the fakes.

A note on the name. Chub was previously CharHub, so the GitHub organisation is CharHubAI and the APK host is charhub.io. Those are the same project, not impostors. How these were confirmed is on the methodology page.
The official app, and the fakes crowding around it
The app story is not simple. Chub was removed from the Google Play Store in February 2025, and Apple pulled the iOS app the same year, both over the adult content the models could produce. Some community sources still point to a directly-distributed Android APK on charhub.io, while other 2026 reviews say there is no maintained mobile app at all. The sources disagree, so treat mobile as unreliable and the web version at venus.chub.ai as the surface you can count on.
The gap left by the missing store listings gets filled with junk. Search results for the app surface Chub AI mod, premium unlocked, helper and advices packages on third-party stores. None are official. Premium runs server-side and cannot be flipped by a local patch, so a mod claiming otherwise is either useless or malware wearing a Chub label.
Before it was pulled, the iOS build was deliberately more restricted than the web to satisfy Apple, and that tells you the pattern: whatever mobile access exists is narrower than the browser. If character creation or model switching is why you are here, do it on desktop.
Chub also had a rough 2025 on payments, with PayPal freezing its account, which is part of why the community leans on cryptocurrency for subscriptions. None of that stops the platform working in a browser. It just means the mobile and payment paths are the fragile parts, not the core.
Is Chub AI down, or is it just you?
Chub is a frequent DDoS target and runs a lot of its own infrastructure, so outages happen. Here is how to tell what you are hitting.
| What you see | Likely cause | What to do |
|---|---|---|
| status.chub.ai red, reports on r/Chub_AI | Platform-wide outage: DDoS, Aphrodite maintenance, or a hardware move | Nothing client-side helps. Wait it out, usually under an hour |
| 502 or 503, "checking your browser" | Cloudflare choking on a traffic spike | Hard refresh with Ctrl+F5, then wait it out |
| Blank screen or MIME complaint | Old cached script after a site update | Clear site data for chub.ai and reload |
| 504 or "API connection error" | Your model provider, not Chub | Switch model or check OpenRouter or OpenAI status |
| Login loop, only for you | A blocked VPN exit node or ISP route | Toggle the VPN, switch region, or change DNS |
The status page updates a touch slower than the subreddit, so when reports start stacking on r/Chub_AI you can assume the team already knows. This flow was checked against outage write-ups across 2025 and 2026 and is summarised in the methodology page.
What Chub AI actually costs
Three tiers, and one billing detail the headline prices hide.
| Tier | Headline price | What lands on your card | Native models | Memory |
|---|---|---|---|---|
| Free | $0 | $0 | Small starter models, or your own API key | Short |
| Mercury | $5 / mo | ~$20 every 4 months | Mistral 7B, MythoMax 13B | 8K tokens |
| Mars | $20 / mo | ~$80 every 4 months | Soji 671B, Asha 70B, Mixtral 8x7B | Up to 30K |
There is no credit or token menu. Your tier decides the models, and that is the whole pricing. Both paid plans bill in mandatory four-month blocks, so you cannot sample Mars for a single month, and there is no annual discount and effectively no refund. Independent reports also flag that card payments fail often and can trigger a bank fraud alert, which pushes most regulars to cryptocurrency. When a card does clear, the charge reportedly shows on your statement as Postcron rather than Chub, so do not panic when you see it.
Models and memory: the part people underestimate
Chub separates the character from the engine. The character card stays fixed while you swap the model underneath. Paid tiers give you hosted models, but the real unlock is bring-your-own-key: paste an OpenRouter, OpenAI, Anthropic or KoboldAI key and you run high-end models on a free account, paying the provider directly instead of Chub. Subscribers even get OpenAI-compatible proxy URLs to pipe Chub's own models into outside tools, which almost nothing else in this category offers.
Chub built its own inference stack, the Aphrodite engine, which is also why maintenance on it takes the site down now and then. The trade-off for all this openness is a steep start. If you want to open an app and talk, this is not that.
The feature that carries long stories is Lorebooks. Instead of stuffing every world detail into the prompt, you store locations, factions and rules as separate entries that fire only when a keyword shows up in the chat. That keeps token use down and stops the model forgetting who runs the docks three scenes later. For anyone building a world rather than a single scene, it matters more than raw model size.
Two more builder tools sit on top: Stages, which add custom interface or mini-games to a chat, and Extensions. Both are open on the CharHubAI repositories, so a developer can fork a template and ship. That is the project repository people ask for, and it is genuinely public.
The character library and what runs it
The public library holds more than 60,000 community cards as of early 2026, and the mix runs wider than the anime front page suggests: original characters, game and show personas, historical figures, horror leads, slice-of-life. Every card is a V2 Character Card, which means personality, speech style, example dialogue, behaviour limits and scenario all travel with it. Cards import cleanly from TavernAI and SillyTavern, so the large stock of community cards on hubs like the old CharacterHub is usable without conversion.
Quality is uneven because the library is entirely user-made, and the honest signal is the interaction count and comments on a card, not its thumbnail. A card with heavy use and repeat praise for consistent memory is a keeper. Three lines of description and no history is a skip. The built-in image generator pairs with all of this for portraits and scene images, with generation included rather than metered, though it sits in a separate panel and caps prompts at about 200 characters.
If Chub is not the fit: five alternatives
The right fallback depends on one thing: whether you value setup-free chat, price, an open library, or visuals.
| Platform | Best for | NSFW | Setup | Starting price |
|---|---|---|---|---|
| Character.AI | Scale, writing quality | Not supported | None | Free · Plus $9.99 |
| Janitor AI | Simple hosted roleplay | Yes, often via proxy | Light | Free · paid models vary |
| SpicyChat | Big free library, no ID gate | Yes, age-only | None | Free · Plus $5 |
| CrushOn AI | Straightforward paid NSFW | Yes, paid | None | From $5.99 |
| Candy AI | Photoreal visuals, voice | Yes, paid | None | From $13.99 |
Prices reflect current listings and change often in this niche. The trade-off Chub makes against all of these is the same one every time: more control, more setup. How this site positions itself next to the platforms it names is on the about page.

Chub AI - questions people actually search
What is Chub AI?
Chub AI (chub.ai) is a character chat and roleplay platform. It formed in May 2024 when Venus AI, a roleplay chat interface, merged with CharacterHub, a public character repository that had gone live in 2023. It hosts more than 60,000 community characters, lets you connect almost any language model, and is built for people who want to control the character and the model behind it. It is an 18+ platform.
Where is the official Chub AI site?
The main domain is chub.ai. The roleplay chat interface lives at venus.chub.ai, with chat.chub.ai as a related surface. Developer docs are at docs.chub.ai and the uptime page is status.chub.ai. Anything on a different domain calling itself the official Chub is not it.
Is Chub AI free?
Yes. The free tier lets you browse and build characters, chat on the small native models, and export your chats. Independent reports put the free native chat at roughly 59 messages before you need a plan or your own API key. Bring your own key from OpenRouter, OpenAI or Anthropic and you can run stronger models at no cost to Chub, paying the API provider directly. Paid tiers are Mercury at 5 dollars a month and Mars at 20 dollars a month.
Is Chub AI down right now?
Check status.chub.ai and the r/Chub_AI subreddit first, since the community and staff usually post an incident within minutes. Through 2026 the recurring causes have been DDoS attacks, maintenance windows on the Aphrodite inference engine, Cloudflare 502 and 503 errors during traffic spikes, and planned downtime from moving to self-owned hardware. Most incidents clear inside an hour. A 504 or API error usually means your model provider, not Chub.
How do I log in to Chub AI?
Open venus.chub.ai or chub.ai, choose sign in, and pick email, Google, GitHub or Apple. The same account works wherever you sign in. If a VPN sends you into a login loop, switch it off or change region, since some VPN exit nodes are blocked.
Does Chub AI have an app?
The app situation is messy. Chub was removed from the Google Play Store in February 2025, and Apple pulled the iOS app the same year over the adult content its models could produce. Some community sources still point to a directly-distributed Android APK on charhub.io, while other 2026 reviews say there is no maintained mobile app. Treat mobile as unreliable and use the browser at venus.chub.ai. Ignore any Chub AI mod, premium unlocked, helper or advices APK on third-party stores, since none are official and some carry malware.
What is Venus Chub AI?
Same platform. Venus AI was the chat interface before the 2024 merger, so the community still calls the roleplay side Venus Chub AI. It sits at venus.chub.ai. All Venus accounts and character data carried over to Chub.
Does Chub AI support NSFW roleplay?
Chub itself does not filter text, so what is allowed depends on the model you connect. A hosted or your-own Claude or GPT key applies that provider's limits, while local and community models run open. Image generation is stricter than text, and content involving minors is banned outright and moderated. The platform is 18+ with age verification before full access.
How much does Chub AI cost in 2026?
Free is zero. Mercury is 5 dollars a month and adds Mistral 7B, MythoMax 13B and an 8K memory window. Mars is 20 dollars a month and adds Soji 671B, Asha 70B and Mixtral 8x7B plus voice. The catch: both paid tiers bill in four-month blocks, so the charge that lands is closer to 20 or 80 dollars up front, with no true monthly option and effectively no refund. Independent reports say card payments often fail, so the community leans on cryptocurrency.
Chub AI vs Janitor AI: what is the difference?
Janitor AI is the simpler, hosted option that gets you chatting fast. Chub is builder-first and model-agnostic, with Lorebooks, Stages and bring-your-own-key support that Janitor does not match. By traffic Chub sits below Character.AI and Janitor, but it is ahead of both on how much you can control.
What are the best Chub AI alternatives?
Character.AI for SFW scale and writing quality, Janitor AI for a simpler hosted setup, SpicyChat for a large free library with no ID gate, CrushOn AI for straightforward paid NSFW, and Candy AI for photorealistic visuals and voice. The comparison table on this page lines them up.
Where is the Chub AI community and project repository?
The subreddit is r/Chub_AI and there is an official Discord linked from chub.ai. The open project lives under the CharHubAI organisation on GitHub, which holds the Stages and Extensions templates and source. Developer documentation is at docs.chub.ai/docs/stages.
Is Chub AI safe and private?
Traffic runs over HTTPS, but Chub does not use end-to-end encryption and stores chats server-side, so treat anything you type as potentially readable. As of early 2026 free-tier chat history is wiped after 30 days, so export a story you care about. Chub says it does not sell data and collects little beyond a username. Access is geofenced: Canada, the UK and New Zealand get a filtered version, Australia has no access, and some US states face restrictions.
