What Is Jade Note? An AI Memory Layer for the ChatGPT/Claude Era

Key takeaways

• Jade Note is both a casual second brain and a persistent memory layer for AI.
• Through MCP, ChatGPT and Claude can search, create, append, and link notes.
• The product is designed so users and AI can grow the same memory together.

Jade Note is a simple second brain: write notes, and reflect on them together with AI. But it has a second identity, too — it is a persistent memory layer for LLMs.

Conversations with ChatGPT or Claude vanish when the session ends. Everything the AI learned about you, every decision you made together, every idea you refined — Jade Note is the place where that memory lives on.

One App, Two Faces

1. For humans: a casual second brain

Using Jade Note is deliberately simple.

• Just sort by category — Learning, work, life logs, ideas, shopping lists. Split notes into categories and they stay easy to revisit — and easy for AI to consult.
• Ask your notes — “Summarize what I learned this week.” “What should I do next based on this category?” The AI answers from your own records: summaries, reflections, next actions.
• Automate recurring reviews — Weekly reviews, writing feedback, habit check-ins: triggers let AI handle scheduled reflection for you.

No plugins, no template engineering. It works comfortably on your phone, so you can capture a thought the moment it appears.

2. For AI: a persistent memory layer

At its core, Jade Note is an external memory store that LLMs read and write through MCP (Model Context Protocol).

Connect Claude Desktop, ChatGPT, or any MCP-compatible client, and the AI can:

• Semantically search your notes to recover context mid-conversation
• Actively save facts and decisions with create_note / append_to_note
• Connect notes with typed links (related, parent, child, continues, references) to grow a knowledge graph
• Rely on automatic versioning — every write can be previewed first and rolled back later

Your notes stop being something the AI merely reads. They become a memory the AI tends and grows.

Why a Memory Layer, Why Now

LLMs don’t remember across conversations. Built-in memory features exist, but they’re locked inside each service. Jade Note takes the opposite stance: memory belongs to the user, not the app. One memory store, read and written simultaneously by Claude Desktop, ChatGPT, the web app, and automated triggers.
