Most platforms we review are apps that happen to have characters. Chub AI is the opposite: a giant character archive that happens to have a chat window. That inversion explains everything about it — the strengths, the roughness, and why its audience is so loyal.

Chub started life in 2023 as CharacterHub, a place to share character cards after Character.AI's filter drove its roleplay community into exile. Three years later it hosts hundreds of thousands of cards, runs its own chat models, and has become the de facto supply depot for the entire uncensored roleplay scene.

We spent two weeks testing it: browsing and grading the library, chatting on the free and paid models, plugging in an outside API key, and exporting cards to other frontends. Here's what we found.

Two Products in One

Understanding Chub means understanding that you're looking at two things sharing one website:

• The Hub — a searchable database of community-made character cards. Each card bundles a personality prompt, greeting, scenario, and example dialogue into a portable file you can chat with on Chub or download for use anywhere else.
• The chat (Venus) — Chub's built-in interface for talking to those cards, powered by the platform's own models or by any outside model you connect.

Competing platforms like Janitor AI and SpicyChat keep their characters locked inside their own walls. Chub treats cards as files you own. That single design decision is why serious roleplayers gravitate here even when the built-in chat isn't the best available.

The Card Library: Scale Without a Safety Net — 9.5/10

The library is enormous — comfortably in the hundreds of thousands of cards, spanning anime, fandom, original characters, and every roleplay scenario the community has thought to write down. Tag search is granular: you can combine genre, setting, personality traits, and content tags to narrow a search precisely, and blocklist tags you never want to see.

Quality control, on the other hand, is your job. Chub deliberately does almost no curation. For every meticulously written card with paragraphs of example dialogue, there are a dozen three-line efforts that produce flat, repetitive chats. The rating system helps — sorting by stars or downloads surfaces the good stuff — but discovery still takes more digging than on curated platforms.

A concrete example from our testing: we pulled ten trending NSFW cards and graded their writing. Four were excellent (detailed personas, distinct voices, scenario hooks that gave the AI something to work with). Three were serviceable. Three were essentially a name and a fetish tag. That spread is the Chub experience in miniature: the ceiling is as high as anywhere, and the floor doesn't exist.

One more thing the scale buys you: niches. If your interest is specific — a particular dynamic, an obscure fandom, a scenario type nobody else hosts — Chub almost certainly has cards for it. The mainstream apps like Candy AI cover the popular fantasies well; Chub covers all of them.

Chatting on Chub: Free vs Paid Models — 6.5/10 free, 7.8/10 paid

This is where expectations need managing. Chub's free chat model is usable but noticeably weak: shorter replies, more repetition, and a tendency to lose the plot in longer scenes. It's fine for sampling cards; it's frustrating for a two-hour roleplay session.

The paid tiers change the picture. Subscribing unlocks Chub's stronger in-house models, which write better prose, hold more context, and stay in character far more reliably. On the top tier the experience is competitive with other community platforms' premium offerings — though still behind purpose-built companion apps like Candy AI, whose models are specifically tuned for romantic and intimate conversation.

Session memory follows the same gradient. The free model works with a short context window and forgets details quickly. Paid models hold longer scenes together, and lorebook support (world-info entries that inject facts when triggered) lets well-built cards compensate further.

The interface itself is functional and dense: message editing, regeneration, swipes for alternate replies, and per-chat model settings are all there. Nothing about it is pretty, and first-time users will spend a while finding things — but the controls power users want all exist.

Bring Your Own Key: Chub's Real Superpower

Here's the feature that separates Chub from every mainstream competitor: you can connect your own API key from an outside AI provider and chat with any card through a model you choose.

Why that matters, practically:

• Quality on demand. Route your chats through a frontier-class model via an aggregator like OpenRouter and the writing quality jumps past anything the in-house models produce.
• Pay for usage, not a subscription. Light users can skip the monthly fee entirely and spend pocket change on API calls instead.
• No lock-in. When a better model ships anywhere in the ecosystem, you can point Chub at it the same week.

The trade-off is setup friction. You need to create an account with a provider, generate a key, and understand roughly what models cost per message. It's a fifteen-minute job the first time, and Chub's documentation assumes you're comfortable with that. Casual users who just want to open an app and flirt should not start here — that's what GoLove AI and similar polished apps are for.

The SillyTavern Connection

Chub cards use the standard character card specification: a PNG or JSON file with the persona embedded. Download any card and it imports directly into SillyTavern, Agnai, RisuAI, and the rest of the local frontend ecosystem. Cards you write elsewhere upload to Chub just as cleanly.

In practice, a large share of Chub's traffic is exactly this: SillyTavern users treating the site as their card store. If you run local models or a heavily customized frontend, Chub is less a competitor to your setup than its supply chain. No other platform this size offers that portability — Janitor AI characters, by contrast, stay on Janitor AI.

NSFW: Genuinely Unfiltered — 9.0/10

Chub was founded as a refuge from filters, and it has never wavered. NSFW cards sit openly in the library behind an age gate and account-level content settings. The chat models don't refuse, don't moralize, and don't quietly fade to black mid-scene.

Two honest caveats:

• The same openness cuts both ways. Minimal moderation means the library contains extreme and deliberately transgressive content alongside the mainstream material. The tag blocklist is effective — set it up on day one.
• Text only. There's no image generation, no voice, no video. Chub NSFW is prose. If you want visuals with your chat, you need Candy AI, OurDream AI, or a dedicated image generator.

For pure text freedom, only Muah AI and self-hosted setups compete, and neither has Chub's library behind it. See our uncensored AI chatbot guide for the full landscape.

Pricing: Free, Mercury, Mars

Chub's pricing is unusual for the space — cheap at the entry point, and optional at every level thanks to BYOK.

Free

• Full library access, including NSFW cards
• Unlimited downloads and card creation
• Basic chat model (short memory, plain prose)

Mercury — around $5/month

• Mid-tier in-house model with better writing and memory
• Enough for regular casual roleplay

Mars — around $20/month

• Chub's strongest models with extended context for long scenes
• For daily users who want the best on-site experience without external keys

Our take: Mercury is the value pick if you chat on-site. Heavy users comfortable with an API key often beat Mars on both quality and price by going BYOK — which Chub, to its credit, fully supports rather than fights.

Chub AI vs Janitor AI

The natural comparison — both are community card platforms with uncensored chat, and most roleplayers end up trying both.

Bottom line: Janitor AI is the better place to start; Chub AI is the better place to end up. Beginners get a smoother ride on Janitor, while tinkerers who care about model choice and card portability outgrow it and land on Chub.

Pros & Cons

Final Verdict — 7.7/10

Chub AI is the roleplay power user's platform: the best card library and the most flexibility in the space, wrapped in the least welcoming package.

Its bet is the opposite of the polished companion apps. Instead of one curated experience, it gives you raw materials: an ocean of cards, portable formats, model choice, and no filters. If you know what to do with those pieces, nothing else matches it — especially paired with an outside API key or a SillyTavern setup.

If you don't want pieces — if you want to open an app and have a girlfriend with a face, a voice, and photos — Chub will feel like being handed a toolbox when you asked for a car. That's not a flaw so much as a choice of audience, but it's why we score it 7.7 rather than higher: most readers arriving from a search engine want the car.

Choose Chub AI if:

• You want the biggest possible selection of roleplay characters
• You use SillyTavern or another frontend and need a card source
• You want to pick your own AI model instead of accepting a default
• Unfiltered text roleplay is the whole point for you

Look elsewhere if:

• You want images, voice, or video with your chat — that's Candy AI territory
• You want a polished, guided experience out of the box
• You'd rather never see a settings page or an API key
