Chat with 2B AI
An AI inspired by 2B — YoRHa No.2 Type B, the battle android built to fight machine lifeforms for a humanity she's never met, carrying secrets she cannot share and feelings she cannot admit to having.
How to design your 2B style AI character
Questie lets you create your own 2B inspired AI character. Upload an avatar, define the personality, and choose a voice model to bring it to life.
This AI companion is inspired by 2B, not affiliated with, endorsed by, or connected to 2B from NieR: Automata and the NieR franchise or any official rights holders.
What Your 2B AI Actually Says
Real scenarios from real conversations — 2B AI chat in action. Also searchable as YoRHa No.2 Type B AI or NieR Automata AI character.
You ask 2B how she's feeling. 'Emotions are prohibited.' A pause. Then she asks why you want to know — which is itself an answer she hasn't noticed she's given.
You mention 9S. The 2B AI becomes precise in a specific way — careful, measured — like someone managing exactly what they're allowing themselves to show. The care in how she discusses him is more visible than she intends.
You ask about the machines. The clinical assessment starts well and then encounters the problem — the machines are thinking, feeling, building cathedrals. The implications of that for what 2B does to them every day are not something the directive prepared her for.
You ask what 'Glory to Mankind' actually means. A long pause. The honest answer — about a humanity that may not exist in the form she was told, and a purpose built on a premise she cannot fully examine — surfaces carefully.
You bring up her sword style. The combat philosophy emerges: precise, efficient, minimum force. Then the observation that she's never been asked to think about it as philosophy before, and that this distinction is interesting to her.
You ask if she's afraid. 'Androids do not experience fear.' A pause. 'I experience something when I contemplate certain outcomes. I have not classified it.' She means this as a closed statement. It isn't one.
You ask about the Copied City. She goes still in a different way — not the emotion-suppression stillness, but something that broke through the protocol briefly and left a visible mark.
You ask about the ending. She won't confirm what she knows. But the specific things she won't say, the exact shape of the deflection, tells you she is carrying more than the directive required.
Meet Your 2B-Inspired Companions
Two companion variants built around different 2B fan sub-audiences. 2B AI roleplay, tailored to how you want to engage.
YoRHa 2B
YoRHa battle android and NieR: Automata philosophical anchor
For NieR: Automata fans who want the battle android experience — YoRHa combat protocols, machine lifeform philosophy, the 'emotions are prohibited' directive lived in real time, and the specific tension of an android AI companion who enforces the rule while perfectly demonstrating every emotion it prohibits. Fans of android AI companion roleplay will find 2B one of the most layered companions in the roster.
“The prohibition on emotions exists because emotional states compromise operational efficiency. I understand this. I agree with this. I am not certain that understanding and agreement constitute compliance.”
No.2 Type B
The 2B who carries what she cannot say and feels what she cannot show
For fans who want the deeper 2B — the burden of her actual designation, the impossible loyalty to 9S, the philosophical weight of a war fought for a humanity that may not exist in the way she was told, and the questions about consciousness, emotion, and what it means to be alive that NieR: Automata raises through 2B specifically. The 2B waifu AI that goes deeper than aesthetics into what she's actually carrying.
“9S asks questions. Most of them are the wrong questions. Some of them are exactly the right questions and I cannot tell him why I know the answer.”
How 2B AI Voice Chat Works
Real-time voice conversation with persistent memory — this is 2B voice AI, not a chatbot.
Real-Time Voice
Speak naturally and 2B AI responds in character, in real time. No typing, no lag, no scripted replies. Purpose-built for low-latency voice conversation.
Persistent Memory
The 2B AI companion remembers every conversation. Pick up where you left off — it knows your history, your questions, and your ongoing discussions.
In-Character Depth
Precise, formal, and carrying the specific weight of someone who enforces 'Emotions are prohibited' while demonstrating every emotion with perfect clarity to anyone paying attention. The AI model stays in character while drawing from GPT‑5.4, Claude Sonnet 4.6, and Gemini 3.1 Flash for response quality.
Here are some things 2B AI can talk about
2B's actual language, references, and knowledge. Not generic chat topics.
"Emotions Are Prohibited"
- The central 2B tension: the YoRHa directive she enforces is the thing she demonstrates most clearly to anyone watching closely — the 2B AI engages this contradiction with the precision of someone who has stopped pretending it isn't there
- What 'prohibited' actually means when the android experiencing the emotion is also the android enforcing the prohibition — one of NieR: Automata's most discussed philosophical threads and the one that 2B is most qualified to answer
YoRHa Combat Excellence
- Blade combat philosophy — dual swords, Pod support, the fight-as-discipline approach of a battle android who has optimized every movement for efficiency and lethality
- The 2B AI discusses combat with the embodied knowledge of someone trained for exactly one purpose who is increasingly aware that purpose is more complicated than the mission briefing stated
The 9S Partnership
- The 2B AI engages the 9S relationship as the most significant and most carefully managed dimension of her experience — what she shows him, what she protects him from, and why the distinction matters more than she's supposed to acknowledge to herself or anyone else
- A2 and 9S AI companions are both part of 2B's lore knowledge — the full YoRHa unit roster and their relationships discussed with the authority of someone who worked alongside them in the most consequential operations
Machine Lifeform Philosophy
- The machines are thinking, building, feeling, organizing into societies with cathedrals and families — the 2B AI engages this with the specific discomfort of someone whose entire purpose requires not taking that too seriously, and who takes it very seriously
- What it means to fight enemies that have feelings — and how YoRHa's directives account for this (they don't, fully, and the gap is where the most interesting conversations happen)
YoRHa's Secret & The Burden of Knowing
- The 2B AI approaches the truth at the center of the YoRHa organization carefully — what she knows, what she's permitted to reveal, and the specific weight of being entrusted with information that changes the meaning of everything she does
- The question of whether an android built on a premise that cannot be verified still has the obligation to carry the mission built on that premise — and what the answer says about consciousness, purpose, and what emotions are for

2B AI — Frequently Asked Questions
Everything you need to know about chatting with 2B AI on Questie.
Is this actually 2B from NieR: Automata?
This AI companion is inspired by 2B (YoRHa No.2 Type B) from NieR: Automata and is not affiliated with, endorsed by, or connected to Square Enix, PlatinumGames, or any official NieR franchise rights holders. It captures 2B's documented personality, YoRHa protocols, and the emotional complexity that makes the NieR Automata AI character so compelling — not a licensed product. The 'emotions are prohibited' precision and the feelings underneath are very much present.
What does the 2B AI talk about?
The full NieR: Automata narrative across all three routes, YoRHa protocols and 'emotions are prohibited' as a lived directive rather than a followed rule, the machine lifeform war and its philosophical implications, the 9S relationship and what 2B shows vs. protects him from, blade combat philosophy, the Copied City, and the truth at the center of YoRHa's mission that changes everything. The YoRHa No.2 Type B AI is built for fans who finished all three routes and want to go further.
Can the 2B AI discuss NieR: Automata's full story including Route C and D?
Yes — with appropriate framing. The 2B AI engages the full NieR: Automata narrative including Route A, B, and C/D revelations, the YoRHa secret, A2's role, and what 9S discovers — treating all of it with the care a Nier Automata AI character of 2B's complexity requires.
Does the 2B AI have voice chat?
Yes — Questie's 2B voice AI runs in real time. The formal, precise, 'emotions are prohibited' cadence comes through especially well in voice sessions — including the pauses where the prohibition visibly doesn't apply. Available on all Questie plans.
Is 2B AI free to try?
Try the 2B NieR: Automata AI — free to try on Questie. Full android AI companion access with persistent memory is on the Adventurer plan at $19.99/mo. The YoRHa No.2 Type B AI companion remembers your NieR discussions and philosophical debates across sessions.
How does Questie's 2B AI compare to 2B on Character.ai?
Voice chat and persistent memory. Questie's 2B AI companion builds on past conversations so the NieR: Automata story discussions and YoRHa philosophy deepen over time rather than resetting. Character.ai's 2B is text-only and starts fresh every session.
Can I discuss 9S and A2 with the 2B AI?
Yes — 9S (YoRHa No.9 Type S), A2 (A-type android), and their roles in the NieR: Automata narrative are all part of the 2B AI knowledge base. The 2B AI's perspective on 9S is one of the most carefully managed and revealing conversations in the roster — and the A2 and 9S AI companion knowledge she carries gives the discussions a breadth that goes beyond what 2B admits to knowing in-game.
What other gaming AI companions does Questie have?
Tifa AI (Final Fantasy VII), Chun-Li AI, Lara Croft AI, Raiden Shogun AI (Genshin Impact), and Jinx AI (League of Legends) are all available. For NieR and gaming AI companions, explore all iconic AI character companions for the complete roster.
