Give Your AI Agent a Private Memory

The Problem: Stateless AI

Every AI agent today is fundamentally stateless. Each conversation starts from zero. You explain your project structure, your decisions, your preferences — every single time.

Some tools offer "memory" features, but they're shallow: OpenAI stores snippets on their servers (you can't control what's remembered). Claude has no persistent memory at all. Cursor remembers within a session but forgets between them.

The deeper problem: your knowledge, decisions, and context are scattered across dozens of conversations that your AI can never access again.

The Solution: MCP + Encrypted Notes

xNotePadAI solves this with a simple architecture:

Your AI Agent → MCP → xNotePadAI → Your Encrypted Notes

Bearer token auth · 13 tools · Confidential sections excluded · Rate limited

MCP (Model Context Protocol) is an open standard that lets AI agents interact with external tools. xNotePadAI exposes a 13-tool MCP server that any compatible agent can use to read, write, search, tag, link, and organise your notes.

The result: your AI agent has persistent, searchable, encrypted memory that you own.

What Your Agent Can Do

Remember decisions

"Save this: we chose PostgreSQL for the auth service."

Recall context

"What did I decide about the project timeline?"

Organise knowledge

"Tag my research notes and link related ones."

Search semantically

"Find everything about machine learning architecture."

Build over time

Each interaction adds to a growing, searchable knowledge base.

Index for RAG

Notes auto-vectorised for semantic search across your whole notebook.

Why Privacy Matters for AI Memory

Your AI memory contains your most sensitive thinking: business decisions, salary negotiations, architecture trade-offs, personal reflections, client information.

With xNotePadAI:

• Notes encrypted with AES-256-GCM (client-side, before transmission)
• Zero-knowledge architecture (server cannot read your content)
• You control the token — revoke it and the AI loses access instantly
• Confidential sections permanently excluded from all AI access
• No training on your data, no retention after processing
• You own everything — export anytime, delete anytime

Compare this to OpenAI's memory: they store it, they can read it, they can train on it, they can delete it. You have no control.

Setup in 60 Seconds

1. Open xnotepadai.com — start writing (no signup needed)
2. Go to Settings → scroll to Connected Apps
3. Type a name for your connection (e.g. "Claude", "Cursor", "Kiro")
4. Click "Generate Token" — a Bearer token appears (looks like: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
5. Copy it immediately — it won't be shown again
6. Add to your AI agent config:

# Claude Desktop / Claude Code:

claude mcp add --transport http xnotepad https://www.xnotepadai.com/api/mcp/ --header "Authorization: Bearer YOUR_TOKEN"

# Cursor (.cursor/mcp.json):

{"mcpServers": {"xnotepad": {"url": "https://www.xnotepadai.com/api/mcp/", "headers": {"Authorization": "Bearer YOUR_TOKEN"}}}}}

# Kiro:

Install power from GitHub → set XNOTEPAD_API_TOKEN env var

The token authenticates your agent. It's scoped to your notebook only. Revoke it anytime from Settings → Connected Apps.

13 Tools, One Endpoint

The MCP server exposes everything an agent needs:

create_note list_notes get_note update_note delete_note search_notes ask_notes get_versions tag_note link_notes merge_notes archive_note index_notes

No Other Note App Does This

Notion, Obsidian, Evernote, Google Keep, Apple Notes, OneNote — none of them expose an MCP server. None of them let AI agents natively read and write your personal knowledge through a standard protocol.

xNotePadAI is the only note-taking application that functions as both a writing tool AND a private memory backend for AI agents. That's not a feature — it's a category.

The Future

Today: your AI agent saves research, recalls decisions, organises your knowledge.

Tomorrow: every AI agent you use — coding, writing, planning, researching — shares the same private knowledge layer. One notebook that all your tools can access, none of them can own.

That's the vision: your private knowledge. Your AI. Your rules.
