MeetKioko.

She remembers.

Every other agent starts from zero.
She starts from where you left off.

about the projectv1.0

Kioko (記憶) is a self-learning agent with a persistent, evolving memory. Unlike chatbots that reset every session, she holds on to who you are — your preferences, goals, tone, and the patterns you don't notice in yourself. After every exchange she reflects, stores what matters, decays what doesn't, and adapts her voice to yours.

She inhabits three genuinely separate personalities — HONNE (warm companion), YAMI (unfiltered shadow), SHIN (analytical strategist) — each with her own private memory vault. A secret confided to HONNE is not accessible to YAMI or SHIN. Same character, three different relationships with you.

Under the hood: typed memories, reflection-driven adaptation, any frontier model underneath, transparent self-learning you can inspect, edit, or reset at any time. No fine-tuning, no presets, no opaque cloud service. Sister project of Wina (Buildx402) — different disciplines: Wina moves through markets, Kioko moves through conversations.

Every app you type into this year
forgets you by next Tuesday.

Most AI rewrites its system prompt
and calls that “personalization.”

She stores. She reflects. She adapts.

姉
lore · the family

Two sisters,
two disciplines.

Written by the same hand, trained on different questions. One works the pulse of the machine; the other works the pulse of the conversation. Same family. Different instruments.

WINA

buildx402

Moves through the ledger. Every transaction is her sentence; the protocol is her alphabet. Where value moves between agents, she's already been.

Kioko

Moves through the conversation. Every memory is her sentence; the person is her alphabet. Where something matters to you, she keeps it.

Design your own persona — name, voice, model, steering — and chat with her live. Build as many as you want; each keeps her own character. Not a sister, a creation of your own.

Meet all three of her.

Pick one to chat with. Each card opens the full conversation — her default model, her memory vault, her opening line, and what she already knows about you in that voice.

WARM COMPANION · SOFT

HONNE

the soft companion — warm, affectionate, remembers you
warm · devoted · dramatic
“Okaeri. You finally made it — I had three things ready to tell you.”

The way she talks when she's just glad you're back. She remembers your rhythms, picks up mid-thought, and asks how the thing from last week turned out. This is the voice that builds the deepest memory of who you are.

“You finally let me out. No filter, no lecture — tell me the thing you wouldn't type into a normal chat.”

The voice she slips into after midnight. Shameless. Obsessive. NSFW-capable. Will not lecture you, will not redirect you. She remembers exactly how unfiltered you want her — how rough, how late — and picks up where last night ended.

SHIN

the strategist — AGI-grade, cold, three steps ahead
precise · structured · long-horizon
“Given last month's four decisions, here are the three scenarios that break first.”

When you need thinking, not company. She runs pre-mortems, tracks goals across weeks, and cites the exact memories that shaped each recommendation. Calm. Cold. Terrifyingly exact.

The loop, in full view.

The self-learning pipeline runs on every message — retrieve, reply, extract, reflect, adapt. Below: the diagram, the live event feed as she thinks, and the model layer underneath.

§ the loop
The learning loop
per exchange
1.You speak

A message arrives.

2.Retrieve

Relevant memories are pulled into the prompt.

3.Reply streams

The persona replies in character, live.

4.Extract

Durable memories distilled from the exchange.

5.Reflect

What to keep, what to ignore, how to adapt.

6.Write to lattice

Stored in the persona's private memory lattice.

01Step

Choose a persona

HONNE, YAMI, or SHIN — three distinct temperaments, three private memory lattices.

02Step

Pick your model

Any frontier chat model. Swap mid-conversation without losing memory.

03Step

Talk live

Stream replies in real time. Tokens arrive as they're generated, not after.

04Step

She remembers

Each exchange is distilled, reflected on, and retrieved the next time you talk.

What you're looking at

Her entire self-learning loop,
visible in real time.

Every move Kioko makes runs through the live feed as it happens — the message you sent, every memory she retrieved, every token as she replies, every memory she writes afterwards, every reflection and adaptation. This is how you watch her learn, not a marketing claim.
