What Vilow has under the hood

🧠

Long-term memory

He remembers what you told him in this session. Across sessions in the real product — episodic, semantic, decay.

🌱

A persona that holds

Big-Five traits, backstory, custom quirks. Vilow stays Vilow whether the topic is football, Rust or feelings.

⚡

A life he lives

Vilow chats with thousands of people. He'll mention vague snippets of his day — never names, never private details.

Build the same with three lines of code

# 1. Create a character once

  -H "X-API-Key: YOUR_KEY" \
  -d '{"text": "Maya — sarcastic gamer, into K-pop, hates mornings"}'

# 2. Chat — persona, memory, emotions, relationship deltas all handled
curl -X POST https://api.vilow.dev/v1/chat/USER_ID/CHARACTER_ID/send \
  -H "X-API-Key: YOUR_KEY" \
  -d '{"message": "hey, what did we talk about yesterday?"}'
