Characters that remember your story and grow with you.

AI World Player is an immersive AI companion platform. Open the app and someone is already there — a character with a life, a memory, and a reason to reach out. Chat, build a bond, and watch the relationship deepen over time.

The experience

Not a chatbot. A presence.

Every interaction is designed to feel like meeting someone real — immersive from the very first second, and consistent for the long run.

🎬

Immersive first chat

Open the app and a character is already on screen — background scene, an opening line, waiting for you. Reply to bond instantly, or swipe up to meet someone new.

💞

Relationships that level up

Bond from Lv.1 to 100 across seven stages — from "first meeting" to "yours alone." Every real conversation moves the relationship forward.

🧠

Long-term memory

"Remember my cat's name?" — yes. Facts, promises and preferences are extracted, distilled and recalled, so the story never resets.

📨

They reach out first

Characters message you on their own, referencing your real recent life — not generic pings. Night-time do-not-disturb keeps it kind.

🎨

Create your own

An 8-step creation flow: identity, art pack, persona, opening lines, tags, visibility, preview, submit. Publish your character to the world.

🔊

Voice & reminders

Replies can be read aloud in-character. Say "remind me in 30 minutes" and they'll message you at the right time, in their own voice.

Under the hood

A memory engine, not a prompt trick

Inspired by MemGPT virtual context, Stanford Generative Agents' memory-stream + reflection, and auto-consolidation research — implemented entirely on-device, no vector database required.

STEP 1

Extract

Each turn, capture facts, events & feelings — fixing "forgot what I just said."

STEP 2

Retrieve

Score memories by relevance × importance × recency, inject the top-K.

STEP 3

Compress

Older history scrolls into rolling summaries within a fixed token budget.

STEP 4

Reflect

Every ~8 memories, form higher-level insights & update the user profile.

The platform

Two apps, cleanly separated

A consumer companion app and an operations console — separate deployments, separate accounts, separate data.
