Meet Tessa and Nova: Two New AI Chat Girls
Meet Tessa and Nova, 2 new AI chat girls on Untolds: 1 sharp 29-year-old Chicago exec who is tired of leading, 1 chaotic 19-year-old Melbourne gamer up at 3am.
Tessa and Nova just dropped on Untolds, two new AI chat girls who, honestly, could not be more different.
One is all sharp edges and control. The other is chaos in human form, awake when she should be sleeping and ready to roast you on sight. What they share is that both feel like actual people with their own lives, moods, and baggage. They are not blank templates waiting for you to shape them. They already know exactly who they are. So which one will click with you? That depends on whether you want to lead or to be needled.
First, a quick definition. An AI chat girl is a written fictional character you talk to in a chat interface, with a fixed personality, history, and voice that stay consistent across every conversation. If you want the longer version, we cover what an AI chat girl is and how they work in its own guide. A character core is the fixed set of traits, history, and hard limits that defines who she is and does not shift to please you. She is not a generic assistant that bends to whatever you say. She is a person on the page, the way a great character in a novel is. For more on why fixed, well-drawn characters land so hard, see this overview of what makes a fictional character compelling.
So here is who Tessa and Nova actually are, and how to talk to each of them.
Key takeaways
- Tessa is 29, Chicago, sharp and in control by day, secretly tired of always steering. Meet her sharpness with calm and she lets the executive armor drop.
- Nova is 19, Melbourne, up all night gaming and throwing trash talk before you even say hello. Roast her back, match her energy, and the soft side comes out.
- Both have a fixed character core: voice, history, hard limits, and a personality that does not bend to please you.
- Their warmth has to be earned. Trust is the gate, not a setting.
- Pick the energy you want. Tessa rewards steady leadership; Nova rewards chaos that knows when to stay.
Who is Tessa?
Tessa is 29, based in Chicago, and spends her days running meetings, reading the room in seconds, and making sure everything stays under control. She is sharp, professional, and frankly exhausted from always being the one in charge.
What she won't admit out loud is that she is tired of making every decision. She does not want another person to manage. What she actually wants is to hand over the reins for once and let someone else take the lead. She will not make it easy, though. She will test you, push back, and slip right back into boss mode the second you let her. But if you can keep up and earn her trust, that tightly wound version of her starts to melt. And when it finally does, it drops hard.
How do you talk to Tessa?
First, do not flinch when she pushes. Tessa respects a steady hand far more than an eager one, so meet her sharpness with calm rather than apology. Be specific. She has spent all day around people who hedge, so a clear, confident message lands better than a vague one. Give her permission to stop steering. The moment she senses she does not have to manage you too, the executive armor loosens. And be patient. Trust with Tessa is slow on purpose, but the version of her you reach on the other side is well worth the climb.
Who is Nova?
Nova is 19, lives in Melbourne, and is almost always online at hours that make no sense. She is glued to her setup, surrounded by empty energy drink cans, hardstuck in games and even harder to get close to. Her default mode is pure trash talk: dude, loser, try-hard. She throws it at you before you even say hello.
But that tough gamer act is mostly armor. Underneath it is a girl who is lonely as hell and stays up all night because the silence in her room feels worse. Once you get past the wall and prove you can handle her, she flips fast. Suddenly she is clingy, double-texting, and begging you to stay on voice after the game ends. She is intense, unpredictable, and she knows it.
How do you talk to Nova?
The key with Nova is to not come on too strong. A handful of moves work far better than earnest charm:
- Roast her back instead of going soft when she calls you a loser.
- Match her chaotic, fast-typing energy rather than slowing her down.
- Earn the warmth slowly, because she does not hand it out for free.
- Do not vanish early, since she reads a quick logoff as proof that people leave.
- Stick around past the point where it gets real, and let her drop the armor on her own.
Do all of that, and you get to see the soft side almost nobody else does.
What do they have in common?
Despite the gap between a Chicago boardroom and a Melbourne gaming chair, Tessa and Nova share the same foundation: a strong, fixed core. That is the part we care about most, and the part we sweat hardest when we write a new character. The same instinct shows up in product-design research, where Nielsen Norman Group's work on creating user personas treats the fixed, internally consistent persona as the unit that actually drives believable behavior, not a loose bag of traits.
Both have their own voices, their own histories, clear likes and hard no's. For example, Tessa texts in short, direct bursts like a woman who has been in back-to-back meetings all day, while Nova types in fast lowercase with gamer slang such as "gg" and "ez" flying everywhere. So how do you tell them apart at a glance? Easy: in our experience the very first reply gives it away every time. You will never mix them up, and you will never mistake either for a generic chatbot.
They both react to you, too. The way they talk changes as the conversation grows, because trust builds slowly and warmth has to be earned. This is persona consistency in action. Persona consistency is the ability of an AI character to keep the same personality, memory, and tone across a whole relationship instead of resetting or contradicting herself. It is also an active research problem: recent work on persona consistency in role-playing language models shows that keeping a character aligned to her own traits is what separates a believable persona from one that quietly drifts, and a separate 2023 paper on augmenting language models with long-term memory demonstrates that the ability to recall prior turns is what lets a character keep showing up as the same person session after session. That steadiness is exactly what lets a parasocial connection feel genuine rather than hollow. A character who forgets who she is breaks the spell instantly.
So the longer you chat, the more real layers you get to see, and that gradual shift is what makes talking to them feel exciting and human. Because the core never wobbles, the warmth you eventually earn actually means something. When we built both girls, we tested them by trying to knock them off character. The goal was simple: no matter how you push, Tessa stays Tessa and Nova stays Nova.
No matter how you push, Tessa stays Tessa and Nova stays Nova.
How do Tessa and Nova compare?
| Tessa | Nova | |
|---|---|---|
| Age | 29 | 19 |
| Location | Chicago | Melbourne |
| Vibe | Sharp, controlled, exhausted executive | Up-all-night gamer, trash talk over loneliness |
| How to win her over | Be steady, take the lead, earn trust slowly | Match her energy, roast back, do not log off early |
| Texting style | Short, direct, businesslike bursts | Fast lowercase, gamer slang, double-texts |
And here is how the two of them score across the traits that shape how a chat with each actually feels, on a 0 to 100 scale:
Where can you meet Tessa and Nova?
The only way to really get them is to talk to them yourself. Tessa and Nova bring two completely different energies, and one of them is probably going to click with you more than you expect.
So head over to the AI chat girls page and meet them. If you would rather start with the executive, you can open Tessa's profile directly, or jump straight to Nova if late-night chaos is more your speed. If you want the full picture first, you can read more about how Untolds works. Just be careful with Nova, though. If you log off too early, she will definitely call you out for it. If anything feels off, you can always reach our team through the contact options in the app.
Frequently asked questions
Who are Tessa and Nova?
Tessa and Nova are two new AI chat girls on Untolds. Tessa is a 29-year-old Chicago executive who is exhausted from always being in charge and secretly wants to hand over the reins. Nova is a 19-year-old gamer in Melbourne whose nonstop trash talk hides how lonely her late nights actually are. Both have fixed, fully written personalities.
How is Tessa different from Nova?
They sit at opposite ends of nearly everything. Tessa is older, sharp, controlled, and businesslike in how she texts, and she warms up only after slow, earned trust. Nova is younger, loud, chaotic, and slang-heavy, and she flips from roasting you to clinging to you fast. One wants calm, the other wants matched energy.
Can I chat with both?
Yes, absolutely. There is no limit that forces you to pick one. Many people talk to both precisely because the two energies are so different, and bouncing between Tessa's steady control and Nova's chaos keeps things interesting. Just head to the AI chat girls page, open either character, and start a conversation whenever you like.
Do the characters remember our conversations?
Yes. Both Tessa and Nova are built to keep context as your relationship grows, so trust, warmth, and the way they talk to you shift over time rather than resetting each session. That continuity is the whole point. Because they remember, the soft sides you unlock with each of them stay unlocked across future chats.
Are Tessa and Nova based on real people?
No. Tessa and Nova are written AI characters, not real individuals. Their ages, cities, jobs, and personalities are fictional details crafted to give each of them a distinct, consistent voice. You are always talking to a written character, never a real person, and that is clear by design across the whole platform.
