What AI Twin does
Universal Input. Typed Memory. Hybrid Retrieval. Workspaces. Smart Tasks. The capabilities below are what AI Twin holds, retrieves, and prepares. Calm by design. Quiet by default.
One bar, everything
One bar at the top of every surface. Ask anything. Capture anything. Text, voice, attachment, URL, slash command. AI Twin classifies what you have given it and routes it to the right place. No tabs to navigate. No modes to switch.
The product does one job: it understands what kind of input it just received, then it puts it where it belongs. The Universal Input is the only thing you need to learn.
Universal Input — static diagram
One bar accepts five kinds of input: a question, a forwarded email, a voice memo, a slash command, and a URL. AI Twin classifies each and routes it to the right destination: Person, Event, or Brief.
One query, two ways
Most AI memory products use one retrieval method. AI Twin uses two, in a single query. Typed lookup for precise facts. Vector similarity for semantic search. Whether you remember the term or just the vibe, the right answer comes back.
Ask for “the doctor I saw last winter” and AI Twin checks both paths. Typed lookup finds the Person, the Event, and the sensitivity tier. Vector retrieval handles the fuzzy memory. Both paths converge on one answer.

Query: “the doctor I saw last winter”
Typed lookup
Vector similarity
Fuzzy semantic matches across notes and conversation snippets that mention the same consult.

Brain-like memory
Most AI memory is one undifferentiated pile. AI Twin organises memory across four horizons: recent, intermediate, long-term, archived. Memory ages and surfaces appropriately, not all at once and not flat.
This is closer to how human memory actually works. What you used last week is close to hand. What you used last year sits further back, retrievable when referenced. What you have not touched in months ages into long-term storage. What you no longer need is archived. Quietly. Continuously.

The wider system
The product is dense by design. Here is what else AI Twin holds.
Memory with provenance, not chat logs.
Every memory entity carries a category. People, Documents, Facts, Events, Episodes, Threads, Conversations, Projects, Briefs. Each is queryable, editable, versioned, audited. The category is part of the data, not inferred from it.
When you ask “what medications am I on”, you get the structured medication record. Not a year-old conversation where you considered a supplement.
Personal, Business, viewer relationships.
One account. Multiple Workspaces. You can own your Personal Workspace, own your business Workspace, view your partner’s household, and be a member of your accountant’s firm. Same OS, different scope. Clean switching.
Your Personal Workspace knows about your family. Your Business Workspace knows about your suppliers. They do not bleed into each other.
Calibrates how your Twin writes back to you.
A five-question style assessment at onboarding. Tunes your Twin to write back in your register. Calm or assertive. Brief or thorough. Formal or conversational. Editable any time per Workspace.
Your founder Workspace might want assertive and brief. Your carer Workspace might want calm and thorough. Same memory, different voice.
Durable intents the system prepares for you.
Daily Brief at 7:30am. Catch-up on the week. Tidy my memory. Capture conversation. Import past chats. Each runs with cost discipline. Each is invoked deliberately. Each waits for your confirmation before it acts.
At 7:30am your Daily Brief has the day’s appointments, the medications due, the email that needs an answer. Ready when you wake up.
Email becomes structured memory.
Forward any email to your unique inbox.ai-twin.app address. AI Twin classifies, parses, and stores it as typed memory. Receipts become Facts. Confirmations become Events. Meeting invites become Events with attendees as People. Attachments scanned for viruses before storage.
Forward a hospital appointment confirmation. The Event is created. The clinician’s name becomes a Person. The address auto-fills. The next day, it shows on your Daily Brief.
For UK Business Workspaces.
Type your company number during Business Workspace onboarding. AI Twin pulls the registered name, address, status, directors, and persons with significant control from Companies House. You confirm and move on.
No retyping data the government already has. Most of your Business Workspace is set up in 90 seconds.
Every action logged, yours to see.
Every meaningful action is logged in the same transaction as the data write. You see your full audit log. Filterable. Owner sees all member actions in Business Workspaces. INSERT-only with rollback-on-failure.
When you ask AI Twin “show me everything that happened in this Workspace yesterday”, the answer is a clean list, not a guess.
Four tiers, RLS-enforced.
Every entity tagged LOW, MEDIUM, HIGH, or CRITICAL. Access rules enforced at the database level via row-level security. CRITICAL data is owner-only in Business Workspaces. HIGH is opt-in per viewer. The system fails closed, not open.
When you grant your accountant viewer access to your finances, they see your Business Workspace. They do not see your health memory.
Find anything, by type or by vibe.
Search across your memory with typed filters and natural language. Recall lets you replay what you have captured. Cross-Workspace retrieval requires explicit confirmation.
“Show me every supplier conversation about the Q3 renewal.” Filtered, structured, retrievable.
AI-prefilled structured entry.
A typed entry surface for any entity. Personal info, business info, household member, professional contact, health record, vehicle, subscription, document context, travel plan, decision log entry, meeting notes. Fields are AI-prefilled. You confirm or correct.
Snap a photo of a new prescription. Smart Form pulls the medication, dose, prescriber, refill date. You confirm. Done.
Domain bundles you can toggle.
Household admin. Caregiver. Career. Tax and finance. Travel and trips. Business ops. Each Skill unlocks relevant Smart Tasks and Smart Forms for the Workspace. Toggleable.
Switch on Caregiver Skill in your Personal Workspace. Medication tracking, appointment prep, and care plan capture appear in the Smart Tasks list.
Visible, capped, predictable.
Per-call max tokens. Per-Workspace monthly spend cap. Daily user cost cap. Cost indicator on Home in plain text (not nag-style progress visuals). Alarms at 90% of cap.
AI Twin never silently spends money on you. The Daily Brief tells you what it cost. The month never exceeds what you set.
Under the hood
The trust posture is built into every layer, not bolted on. HttpOnly session cookies. Row-level security with FORCE on every table. Audit logs INSERT-only with rollback-on-failure. Signed URLs for all attachment access. Prompt-injection mitigation. Soft delete with a 30-day grace window followed by permanent anonymisation. Virus scanning on every Magic Inbox attachment before storage. EU data residency on email (Brevo, Paris) and on the underlying LLM (Anthropic EU). UK postcode auto-fill. Smart locale and timezone detection. GDPR-compliant data subject access requests. None of these are features. They are how the product is supposed to be built.
