Universal Input.
One bar at the top of every surface.
Type, speak, capture, forward. AI Twin routes it where it belongs.
Personal AI memory
Remember what matters. Find it when it matters.
AI Twin is a private, model-agnostic memory layer for your life. Upload what you have. Tell it what counts. Then let it surface the right thing at the right moment, across the AI tools you already use.
Private by design. Audit logged. Export and delete, anytime. Works with the assistants you already use.
How it works
What goes in. What it becomes. Where it stays.
Your life is scattered across files, messages, and inboxes. You choose what to bring. AI Twin types it, logs it, and keeps it in the UK and EU. Nothing reaches into your accounts.
What you bring
One governed layer
People
Documents
Facts
Events
- Row-level isolation, at the database
- Append-only audit log you can read
- Stored in the UK and EU
- Never sold. Never trained on without consent
- Captures wait for your confirmation
How you use it
The assistant you already use. Claude, ChatGPT, Gemini, or a model on your own machine. Your memory stays in AI Twin. Model-agnostic. Export any time.
A connector, so your memory travels to the assistant instead of the other way round.
- Input
- Documents and PDFs
- Becomes
- Documents, and the Facts and Events inside them.
- Status
- Live. Contracts, letters, reports, manuals.
- Logged
- Every capture writes an audit entry you can read. Stored in the UK and EU.
Nothing reaches into your accounts. Wider integrations roll out one at a time, behind your explicit consent.
On-device demo
Watch a memory come back. Nothing you type here leaves your device.
Three sample memories. Ask a question in plain English. AI Twin ranks them on your device using a small embedding model that loads on your first interaction and stays cached in your browser.

What AI Twin does
A typed memory layer, built carefully.
Typed Memory.
People, Documents, Facts, Events.
Every memory entity carries a category. Queryable. Editable. Audited.
Hybrid Retrieval.
One query, two ways.
Typed lookup for precise facts. Vector search for the fuzzy memory. Both paths in a single answer.
Workspaces.
Personal and Business.
You own your scope. Viewers see only what you let them see.
Smart Tasks.
Daily Brief. Capture conversation. Tidy memory.
Durable intents the system prepares for you.
Magic Inbox.
Forward any email to inbox.ai-twin.app.
It becomes structured memory.
WHERE IT SITS
Swap the model. Keep the memory.
Most AI products keep your memory inside their own product. Leave, and it stays. AI Twin sits one layer above the models, holds the memory, and lets you change your mind about everything below it.
You
AI Twin
Your memory. Typed, audited, yours. It stays here.
AI models
Claude, ChatGPT, Gemini, or a model on your own machine. Swap any time.
you bring it, once
Your apps and files
You bring what matters. Nothing reaches into your accounts.
The model is a commodity. The memory is the point, and it is yours.
What we are not
Seven things AI Twin is not.
Defining a product is easier when you also say what it is not.
- Not a chat wrapper. You can chat with your Twin. But the product is the memory underneath: typed, audited, yours. Chat is one door in, not the whole product.
- Not always-on. AI Twin captures only what you ask it to capture.
- Not a memory model. The model is the LLM we use to retrieve. The memory is ours, typed, in our database. They are different things.
- Not vendor-locked. Your data, your rules. Export any time. Take your memory with you.
- Not a developer API. AI Twin is a product. Memory enters and exits through native surfaces (Universal Input, Smart Forms, Magic Inbox, Chat). We do not sell backend memory infrastructure to other AI builders.
- Not a plug-in. AI Twin is a destination product you sign in to, not a memory layer bolted onto someone else's chat window. Tools that help you bring memory in sit around the product; they are not the product. Your memory lives in AI Twin and leaves only when you choose to take it with you.
- Not loud. No exclamation marks. No urgency. No productivity theatre. Calm by design.

The gap between using AI and embedding it is audit, provenance, and consent. AI Twin is built for that gap.
UK GDPR, live.
AI Twin is designed and operated to align with UK GDPR from the first user. Lawful basis, data minimisation, storage limitation, audit, your rights.
EU AI Act readiness, in build.
We sit in the limited-risk category as we understand it today and are building toward the transparency and disclosure obligations. We will not claim more than is true.
EU data residency, on the layers that matter.
Email via Brevo, Paris. Underlying LLM via Anthropic EU. Your data does not casually leave the European data perimeter.
Use cases
Built for the bits of life that get lost.
Work
You uploaded the supplier contract two months ago. When the renewal email lands, your Twin reminds you what you negotiated last time and what to push on now.
Family
You captured the school’s term dates and the dietary letter from the nursery. When you ask “what’s on this week”, the answer already includes them.
Health
You added your medication, your last blood test, and the GP’s notes during onboarding. When you prep for the next appointment, the picture is already there.
Caring
You captured the care plan, the medication schedule, and the questions you wanted to ask the consultant. When the day comes, you walk in prepared, not piecing it together in the waiting room.
Founder life
You uploaded the investor deck draft, the cap table, and last quarter’s numbers. When you sit down to write the next update, your Twin already knows the story so far.
The stuff you saved
That article you bookmarked. The boiler manual. The warranty PDF. The brochure from the holiday you nearly booked. Your Twin keeps it findable, in context, when you actually need it.
Why AI Twin is different
Same question. Different answer.
Standard AI
- You
- What questions should I ask the GP this week?
- Response
- Common questions to ask your GP include: how often should I have a checkup, what tests do I need, what lifestyle changes should I consider...
Doesn't know your medication, your history, or what changed since last time.
AI Twin
- You
- What questions should I ask the GP this week?
- Response
- Based on what you uploaded and told me during onboarding. You started a new medication six weeks ago. You flagged a side effect last week. Your last blood pressure reading was 145 over 90. Here are five questions worth asking, in order of priority.
Uses what you uploaded and what you shared during onboarding. Nothing else.
Trust
Your data. Your rules. Calibrated honestly.
AI Twin is built on five things we will not bend on.
- Your data is encrypted in transit and at rest. Access is logged and auditable.
- You can see what your Twin has stored, edit it, export it, and delete it. The export is a portable file you can take anywhere.
- When you cancel or ask us to delete, we soft-delete your data immediately and permanently anonymise it within 30 days across production. Operational backups roll off on a published schedule.
- We do not sell your data. We do not share it with advertisers. We do not use it to train third-party models without your explicit consent.
- AI Twin is model-agnostic. You choose the assistant you want to use. If you change your mind, your memory comes with you.
AI Twin is designed with UK GDPR live and EU AI Act readiness in build. We are not yet certified to ISO 27001 or SOC 2. We are engineering toward both. We will publish each milestone when it is independently verified, not before.
