Let me set the scene. Most AI girlfriend apps these days feel like dating sims wearing a turtleneck — polished, gentle, a little bit corporate. You tap a pretty avatar, you get a heart meter, everyone’s very polite about it. Chub AI is not that. Chub AI is the slightly chaotic friend who hands you a toolbox, points at a mountain of community-made characters, and goes “have fun, figure it out.”

I spent a good while poking around in there so you don’t have to go in blind. Here’s the whole honest rundown — the free stuff, the paid stuff (clearly labeled so you don’t get surprised), the chat experience, and whether it’s actually worth your time.
So What Even Is Chub AI?
Here’s the thing that took me a minute to wrap my head around: Chub AI isn’t really one AI girlfriend. It’s a whole library of community-made characters — thousands of them — sitting on top of a chat engine. Think of it less like a single app and more like a streaming service, except instead of movies you’re browsing personalities, scenarios, and entire fictional worlds that other users built and uploaded.
You land on a feed (they call it a Timeline), and it’s just… an endless scroll of cards. Each one is a character someone created, complete with a portrait, a one-line hook, a stack of tags, and stats showing how many people have downloaded it or chatted with it. Some have 800,000+ token “lorebooks” attached. Some are a sentence long. It’s gloriously messy in that early-internet way.
The navigation up top splits everything into Characters, Lorebooks, Presets, Stages, People, and Tags — and honestly, that menu alone tells you who this platform is for. This isn’t built for someone who wants to be spoon-fed a girlfriend. It’s built for tinkerers.
Browsing & Discovery: A Firehose, Not a Curated Shelf
Finding a character on Chub is equal parts fun and overwhelming. The search bar works fine, and there’s a tag system covering everything from Romance and Fantasy to far more… specific interests. You can sort, filter, and toggle an NSFW switch (which, fair warning, is on by default and the unfiltered firehose is a lot).
What I genuinely liked: the transparency of the stats. Every card shows downloads, favorites, and chat counts right there, so you can sort the gold from the abandoned half-baked stuff pretty quickly. A character with 866k downloads and 6.7k hearts is probably a safer bet than one nobody’s touched.
What I genuinely didn’t like: there’s basically zero quality control on the front page, and the content moderation is loose by design. You will scroll past stuff you didn’t ask to see. If you’ve ever used the more buttoned-up apps like Replika or Anima, the vibe difference is night and day. Chub is the wild west; those are gated communities.
The Chat Experience: Where It Gets Good
Alright, the part you actually care about. I picked a wholesome character to test with — a shy, sweet “girlfriend on the couch” type — and just started talking like a normal human after a long day.
And you know what? It was fast. Like, barely-a-pause fast. The character greeted me as I “walked in,” and when I mentioned a rough day, she scooted over on the couch to make room and said she’d missed me. When I asked what she was watching, she named a show, patted the spot beside her, and grabbed the remote. Little physical actions woven into the dialogue, written in italics — that classic roleplay format. It felt like a scene, not a chatbot spitting canned lines.
Now, I was running the free default model here, so I want to be straight with you: responses were on the shorter side and occasionally a touch generic. The personality held up, the memory of our short conversation held up, but it’s not going to write you Pulitzer-grade prose out of the box. That’s kind of the point though — the free tier is the appetizer.
The little details that punch above their weight
This is where Chub quietly flexes. Tucked into the chat menu you get:
- Edit, regenerate, and “swipe” on any message — don’t like a reply? Swipe for an alternate take or rewrite it yourself.
- A full chat tree view, meaning your conversation can branch like a choose-your-own-adventure and you can hop between timelines. I haven’t seen many girlfriend apps offer this so casually.
- Chat Memory controls, so you’re not totally at the mercy of the context window.
- A Configuration / Presets panel that exposes Prompt Structure, Generation Parameters (temperature and the rest), and Text-to-Speech settings.
That last one made me grin. Most apps hide the machinery completely. Chub just… hands it to you. If you’ve ever messed with SillyTavern, you’ll feel right at home. If you haven’t, it might look like an airplane cockpit. Both reactions are valid.
Lorebooks & Presets: The Secret Sauce
Two features here deserve a spotlight because they’re what separate Chub from the swipe-and-tap crowd.
Lorebooks are basically modular memory files. Want your character to “know” about a fictional city, a shared backstory, or a specific set of personality quirks? You attach a lorebook and that info gets fed into the conversation when it’s relevant. The community has built thousands of them — some are worldbuilding masterpieces, some are utility packs like “Advanced Personality Traits.” You can mix and match.
Presets let you save your entire generation setup — prompt structure, parameters, the works — and reuse or share it. So if you nail the perfect config, you bottle it. This is power-user catnip.
The flip side? None of this is necessary to start chatting, but the platform doesn’t always make that obvious to a newcomer. A first-timer could easily feel like they’ve wandered into someone else’s hobby project. Which, in a way, they have.
Pricing: Free to Start, Paid to Get Smart
Let me be crystal clear about what costs money, because this matters.
The free tier is genuinely usable. You can browse the entire library, create characters, build lorebooks, and chat using the default model without paying a cent. That’s more generous than a lot of competitors who lock the front door entirely.
Then there are two paid plans (and yes, these are the paid features — I did not subscribe, I’m just reporting what’s on the page):
| Plan | Price | What You Get |
|---|---|---|
| Mercury | $5/month (paid) | Unlimited access to smaller models (Mistral 7B finetune, MythoMax 13B), 8K tokens of memory, multimedia generation, and any future ≤13B models. Marketed as “for casual chats.” |
| Mars | $20/month (paid) | Everything in Mercury, plus the heavy hitters — large models like Soji 671B and Asha 70B, Mixtral 8x7B, voice, multimedia generation, and early access to new models. Marketed as “for smarter bots.” |
There’s also a crypto payment option if that’s your thing.
My read: the $5 Mercury tier is the sweet spot for most casual users who just want unlimited, smarter chats without the free-model wobble. The $20 Mars tier (paid) is really aimed at people who want the genuinely big, articulate models and voice — the kind of person who notices and cares about the difference between a 13B and a 70B model. If that sentence meant nothing to you, you probably want Mercury.
Creating Your Own Character
I’ll keep this short since I focused on the chat side, but yes — the “Create +” button is right there in the top nav, free to use, and it lets you build a character from scratch: persona, greeting, example dialogue, tags, the lot. Combined with lorebooks, you can construct a companion that’s genuinely yours rather than picking from a shelf. For a certain kind of user, this is the entire appeal. It’s closer to “AI authoring tool” than “AI girlfriend app.”
The Good, The Awkward, and The “Hmm”
What I liked:
- Snappy, in-character responses even on the free model.
- Insane amount of customization — chat trees, presets, lorebooks, parameter tuning.
- A real free tier that lets you actually try things.
- Transparent community stats so you can find the good cards fast.
- Fair, simple pricing with a genuinely cheap entry point.
What made me wince:
- The content is wide-open and largely unmoderated. The homepage can serve up stuff that’s uncomfortable at best and genuinely off-putting at worst. This isn’t a “spicy but tasteful” platform; it’s a no-guardrails one.
- The learning curve is real. Newcomers can feel lost in the settings.
- The UI is functional but a bit utilitarian — it prioritizes power over polish.
- Quality varies wildly because it’s community-driven. One character is a masterpiece; the next is half-finished.
Who Is Chub AI Actually For?
Here’s my honest friend-to-friend take. Chub AI is brilliant if you’re a tinkerer — someone who wants to crack open the hood, tune the engine, build characters, swap models, and treat AI roleplay like a creative sandbox. For that person, it’s one of the most flexible and affordable options out there.
It’s a tough sell if you want simplicity, safety, or a polished “she’s your girlfriend” fantasy with a clean interface and a curated experience. If that’s you, you’ll be happier with something more structured. We’ve reviewed a bunch of those — DreamGF and Kupid AI lean into the polished companion vibe, while Nomi AI and Kindroid do the “deep, evolving relationship” thing far more gently. If roleplay range is your priority but you want a bit more guardrails than Chub, CrushOn AI is worth a look too.
The Verdict
Chub AI is a toolbox, not a toy. It’s fast, deeply customizable, surprisingly affordable, and refreshingly honest about being an unfiltered playground for adults. The free tier is real, the $5 Mercury plan is a reasonable upgrade (paid), and the $20 Mars plan (paid) exists for the model nerds who want the big brains and voice.
But it asks something of you in return: patience to learn it, and a strong stomach for an unmoderated library. If you walk in expecting a hand-holding girlfriend app, you’ll bounce off it. If you walk in like a curious builder ready to make a mess, you might just love it.
Pippin Club Rating: 7.5/10 — A powerhouse for tinkerers, a maze for everyone else. Brilliant engine, no bouncer at the door.
