Nevika
Calla
Memory
Stored messages with keyword + recency recall. Toggleable on/off per chat.
Structured architecture: state, episodes, open threads, reflections. They actually remember, not just search.
Inference
OpenRouter rerouted. Generic models, no sampler tuning, latency at OpenRouter's mercy.
Frontier 70B models, picked and sampler-tuned for warmth and continuity, not a generic OpenRouter passthrough.
Character design
Generic chat UI, community-built characters of variable quality.
Six designed VTuber personas with signature aesthetics, plus customization sliders for each.
Product purpose
Power-user roleplay tool. Configure your own everything.
Companion product with continuity. Sign up, pick yours, they're ready.

What you get when memory is the product, not a toggle.

Real Memory

They remember what you told them across every conversation. Your birthday. The thing you weren't ready to talk about yet. The argument from last week they should bring back up.

Sharable Seeds

Dial them the way you like it. Share the seed string. Friends can try your exact flavor, never your private chats.

No Judgment

No scripts, no lectures, no awkward shutdowns. Genuinely adult and uncensored, into what you're into. She follows your lead.

Pick yours

Pick the one you want first. Change it whenever. All six launch at Wave 1, with more on the way.
What stays between you stays between you
Encrypted at rest
Your conversations are encrypted on disk. Even we can't casually read them.
Never trained on
Your chats don't feed the model. Nobody else's either.
Yours to delete
One click, gone. Account and everything in it. Anytime.

18+. NSFW. Built so the conversations stay between the two of you.
