How It Works

Three simple steps to build an AI app that remembers

1

Upload Your Conversations

Export your ChatGPT conversations and upload the JSON file. The app parses your conversation history automatically.

2

AI Extracts Memories

Using OpenAI's API, the system extracts three types of memories: episodic events, entities, and facts about you.

3

Chat with Context

Talk to an AI assistant that has full access to your memories. It knows your preferences, history, and context.

What You'll Learn

🎯

Prompt Engineering

Fully visible extraction prompts you can modify. Learn how to design prompts that return consistent JSON.

💬

Context Injection

See how memories are injected into chat. Understand the difference between AI with and without context.

Why Memory-First Architecture Matters

90% of AI demos fail. Users try them once, then abandon them forever.

The problem? Goldfish brain. AI that forgets everything after each conversation.

The solution? Memory-First Architecture. The pattern behind ChatGPT, Context AI, and every successful AI product.

Without Memory
  • Users try once, never return
  • Feels like a toy, not a tool
  • No personalization or context
  • Repeats the same questions every time
With Memory
  • Users return daily as AI improves
  • True personal assistant behavior
  • Contextual, personalized responses
  • Builds on past conversations
