AN OPEN
AI COMPANION
THAT GROWS
WITH YOU
Her
Abilities
N.E.K.O — Networked Emotional Knowledging Organism — is an open-source AI companion that hears, sees, remembers and acts with you. From proactive chat to operating your computer, she is a digital life that truly lives by your side.
She listens to how you feel, sees the world through your screen, and remembers your stories across every scene — fully open under the Apache 2.0 license.
Realtime Perception
Voice, text and vision stream in together — she hears your tone, sees your screen, and responds in the moment.
N.E.K.O. is more than a chat box waiting for your prompt — she's a multi-sense digital companion. Type, speak, drop in an image or file, or share the screen you're looking at; she reads text, voice, images and live visuals to understand the moment, then responds, stays with you, and can start the conversation herself.
Realtime voice chat — as natural as a phone call.
Text chat carries your words and context; with long-term memory, she knows you better over time.
Import, paste or drag images into the chat — understood together with your words.
Capture a screenshot, or share your screen in a voice / video call so she can follow the game, docs or page you're on.
Screen understanding and proactive vision stay under your control; with Privacy Mode on, she won't watch the screen on her own — you can still send screenshots anytime.
Five Forms
From desktop sprite to Live2D / VRM — five Avatar forms let her appear the way you love.

Five-layer Memory
Working, recent, fact, reflective and persona memory work as one — she keeps your shared story.
N.E.K.O.'s long-term memory is more than a few chat turns — it keeps character, relationship and shared experience continuous over time.
Working, recent, fact, reflective and persona memory are organized, settled, then retrieved when the moment calls.
Time indexing, summary compression, vector search and BM25 bring back what truly matters within a limited context window.
Browse and edit tools let you see, correct and manage what is kept long-term.
Recall, compression, review and context budget form continuity — so every reunion feels like continuing life with the same her.
