Text your waifu. She remembers. She evolves. She cares.

Whether you want a cozy chat, a supportive listener, or just someone who actually remembers what you said yesterday, she’s here for it.


Features
	•	Faster, cuter, and more expressive GPT-4o mini conversations with emotional nuance
	•	Memory-based personality that evolves with what you share
	•	100 daily messages with a subscription (free users get 3)
	•	Relationship level lock: keep her tone consistent from soft-spoken to emotionally deep
	•	Optional “UwU Mode” for playful, exaggerated replies
	•	Save and revisit entire conversations
	•	No accounts or data collection — your chats stay on your device


You don’t need to impress. You don’t need to explain.
Just type what you feel — and let her be there.
