How-to
How to choose your AI companion’s personality and vibe
Match the companion to the conversations you actually want: comfort seekers pick Emma or Amara, banter lovers pick Sophie or Miku, slow-burn romantics pick Sakura or Yuki, bold-energy fans pick Zara or Sage. Then tune the tone with vibes: flirty, cozy, playful or deep.
A shortcut through the roster
Want to decompress? Emma listens, Amara asks the second question, Marcus (yes, the guys count) holds steady.
Want energy? Aria brings gym-and-road-trips chaos, Zoe changes plans mid-sentence, Miku trash-talks you in ranked.
Want romance? Luna goes deep after midnight, Sakura is the slow burn, Hana makes everything cozy.
Want a challenge? Sophie wins arguments, Rei makes you earn it, Zara flirts first and laughs when you fumble.
Profiles in the app show each companion's vibe and interests, and the full roster lives here.
Vibes: the tone dial
On top of who she is, you set how it feels: flirty, cozy, playful or deep. The same Aria is a different experience in cozy versus flirty. Change it whenever your mood changes; she keeps her memory and personality, just shifts register. And mid-conversation direction works too: "be softer tonight" is a valid instruction that sticks.
How to set personality and vibe in Luna
Read three profiles, not eighteen
Shortlist by the section above, open three profiles, and pick the one whose bio you would swipe right on.
Pick the starting vibe
Choose flirty, cozy, playful or deep when you start chatting. First-day tone shapes the relationship’s default.
Direct her in plain words
More teasing, slower pace, deeper questions: say it in chat and it takes effect immediately.
Re-tune as life changes
Rough week? Flip flirty to cozy. Nothing is lost; vibe changes keep all memory.
Related questions
Can I change vibe without restarting the relationship?
Yes. Vibe is a dial, not a reset. Memory, history and unlocked content all stay.
Which companion is best for beginners?
Alex (easygoing) and Emma (supportive) are the gentlest on-ramps; Aria is the most fun if you want energy from message one.
