MyAITwin

A personal RAG database and semantic search engine you build and control from inside your AI chat. Store your knowledge, voice, and skills as you work. Retrieve them in seconds, source always cited. Your AI then creates output that is recognisably you, in every conversation.

Live at https://myaitwin.lutolearn.com. Free during early access.

What it is

MyAITwin is two things at once.

The toolbox. A production-grade RAG database with semantic search that you shape from chat. You define the structure, the types, the tags. It is yours, it is visible, and you are the architect of it.

The twin. The layer on top that greets you, guides you, assesses what you store, and creates output that sounds like you. It knows the difference between what you know (your knowledge) and how you say things (your skills), and it uses both.

Install

Three steps. Under two minutes.

1. Sign up at https://myaitwin.lutolearn.com/ with your email.
2. Click the magic link, then copy your personal MCP URL from /create.
3. In Claude Desktop: Settings → Connectors → Add custom connector → paste your URL.

Or use the canonical OAuth-authenticated endpoint:

• URL: https://myaitwin.lutolearn.com/mcp
• Transport: Streamable HTTP
• Auth: OAuth 2.1 with PKCE (S256) and Dynamic Client Registration

Requires a client with MCP capability. Currently Claude Pro, Claude Team, and ChatGPT Pro.

The 19 tools

Storing knowledge

Tool	What it does
add_knowledge	Store a typed, tagged knowledge item
add_voice_note	Store a voice note transcript with automatic extraction
add_document	Store a long document with automatic chunking
add_from_url	Fetch and store a web page
add_reference_record	Store a creation event linking knowledge and skills used

Retrieving knowledge

Tool	What it does
search_twin	Semantic search across all knowledge
search_for_creation	Dual search returning skills and knowledge separately
get_by_type	Retrieve all items of a specific type
get_by_tag	Retrieve all items with a specific tag
list_recent	List recently added items

Understanding your twin

Tool	What it does
get_schema	Overview of your types and how many items you have
get_sources	List all source documents
find_patterns	Surface recurring patterns across your knowledge
synthesise	Synthesise across multiple knowledge items on a topic

Managing your twin

Tool	What it does
get_welcome	Session initialisation and system prompt
update_knowledge	Update an existing item
add_schema_type	Define a new knowledge type
update_schema_type	Update an existing type definition
delete_knowledge	Delete an item (destructive)

All tools are annotated with title, readOnlyHint, and destructiveHint per the MCP spec. Of the 19: 10 read-only, 8 write (non-destructive), 1 destructive (delete_knowledge).

How it works

RAG is Retrieval-Augmented Generation. It is the architecture that lets AI answer using your specific knowledge rather than its training data alone.

Two layers:

• Supabase (PostgreSQL) for structured records with types, tags, and provenance.
• Pinecone for vector embeddings, so you can search by meaning rather than exact words.

When you search, both layers work together and return results ranked by relevance. Every result is cited with source and date, and tagged with provenance: personal (your own thinking), organisational (from your organisation), or external (from someone else).

The architectural insight worth getting right:

Knowledge is what you know. Facts, decisions, transcripts, observations.

Skills are how you express things. Your LinkedIn voice. Your email style. Your proposal structure.

Exceptional output needs both. Take a meeting transcript and ask for a follow-up email. The twin needs the transcript and your email skill to produce something that is accurate and unmistakably yours. Neither alone is enough.

Security and privacy

• Bearer token authentication on every request, hashed at rest.
• OAuth 2.1 with PKCE for connector-style integration. No shared secrets, no static credentials.
• Multi-tenant data isolation: each user lives in their own namespace. Other users can never read your data. Verified by a 35-check cross-tenant test suite.
• Rate limiting per tenant.
• Append-only audit log on every tool call.
• Prompt injection guardrails on stored content.
• Your data is used only to provide the service. Never used to train AI models. Never shared with third parties.
• You can delete your account and all data instantly from /create. Deletion is immediate and irreversible.
