Why now
Every AI assistant you have been shown runs on zero relationship context
It can read your calendar. It cannot tell you that your sister is vegan, that your biggest client hates phone calls, or what you gave your niece last year. That context has never been structured anywhere — it lives in your head and your message history, and it decays.
Agents are about to act, not answer
Booking, buying, reaching out on your behalf. All of it needs to know who the people are — and right now none of them do.
The details you need decay fastest
Numbers change, jobs change, preferences change. Anything you typed by hand six months ago is already partly wrong.
Nobody owns this layer yet
Contact fields have existed for forty years. Structured, private, subject-maintained relationship context has not.
You askWhat should I get my sister for her birthday?
Claude
I don’t have access to your sister’s wish list or personal information about what she wants.
ChatGPT
I don’t know anything about your sister.
Deeta
She just added a blue scarf from Acne Studios and gloves from Naadam to her wish list.
Full wish list on her profileNobody is being stupid here — the first two simply have no way to know. Her wish list is a detail she keeps on her own profile and shares with you, so it updates on your side when she changes it. Answers from general assistants are illustrative; the exact wording varies.
How it works
A record the subject keeps current — not one you maintain by hand
Every personal CRM that has ever died, died for the same reason: the user had to keep it alive by typing, and the data rotted. Deeta inverts that.
Live records
They update their details. Yours change too.
You share a profile; they share theirs back. From then on it stays in sync. When their number, role or address changes on their side, your side updates itself — nobody re-sends anything, and nobody retypes anything.
- Subject-maintained. The person who actually knows the detail is the one keeping it right.
- It compounds. Every connection makes the rest of your records more accurate, not less.
- Standard fields flow to your phone’s contacts too, both ways, without the two fighting each other.
Left: a record you maintainRight: a record they maintain
You can take it back
The internet doesn’t have to be written in ink.
Everything you have ever shared online was a copy. You sent it, they kept it, and that was the end of your say in it — the only question left was whether they behaved. Sharing here is not a copy. It is a window you opened into your own record, and you can close it.
- Revoke and it is gone. Not "we ask them to delete it", not a request in a queue — the window shuts and their side stops showing it.
- One field at a time. Your mobile can go to your plumber and your address to nobody, and you can change your mind about either without touching the other.
- It cannot be passed on. What you show one person cannot be forwarded to someone you never chose. That is a property of how it is built, not a rule we ask people to follow.
Per-attribute grantsNo onward sharing
Just ask
Ask in plain English. Answered on your device, if you want.
No query language, no filters, no folders — a question the way you would say it out loud, answered from the details you already saved. In Private Mode the whole thing runs on your device, so nothing is transmitted to answer it.
- Plain language, because a tool you have to learn is a tool you stop opening.
- Private Mode answers locally — and reads the phone numbers and addresses the cloud path redacts before sending.
- Or pick your provider — Anthropic, OpenAI, Gemini, Grok, or none at all.

Getting things in
Every tool like this dies of the same thing: typing. So mostly, you don’t.
Your whole address book is here on day one, and it stays that way — synced both ways with your phone, so anything that lands in your contacts lands in Deeta, and any edit you make here shows up there. Nothing to import, nothing stranded in a second app. After that a detail takes about two seconds, in whatever way suits the moment you’re in.
Capture
Say it, paste it, or save it from wherever you already are
The detail you want is almost never in front of you at a keyboard — it is in a conversation, a message, or a passing remark. So capture goes where you are rather than asking you to come to it.
- Just say it. Talk, pause, think, keep talking — the session holds your transcript and waits, and you commit when you are done. Transcribed on your device.
- Type or paste. Drop in a chunk of an email or your own scribbled notes and it pulls out the individual details for you to confirm.
- Straight from Messages, or any other app. Share it to Deeta and it is saved against the right person without you leaving the app you were in.
- Someone sends you their digital business card? Share a Blinq, HiHello or Popl link to Deeta and it arrives as real, structured details — name, title, company, numbers, socials — not a dead URL you will never open again.
- Or they just AirDrop you a contact. Send it straight to Deeta — by AirDrop, or from a Mail or Messages attachment — and it comes in as details to confirm, rather than a card you have to file somewhere else first.
- From an answer. Ask a question, then turn what comes back into a saved detail in one tap.
- Or type it. Manual entry is still there, still quick — and edits flow back to your phone’s contacts automatically.
Two seconds per detailNo import to sit through
For example
Ask it the way you would ask a friend who remembered everything
No query language, no filters, no folders. It answers out of the details you have already saved.
- What should I get Dave for his birthday?
- Who do I know who has been to Lisbon?
- Which of my clients mentioned budget this quarter?
- Who did I meet at the conference in March?
- Whose birthday is this month?
- Which of my friends has a kid the same age as mine?

Your data. Your AI. Your choice.
You pick the AI. Including none of them.
Most apps hardwire one AI vendor and never mention it. You choose which one answers your questions — and whether one leaves your device at all.
Choose your provider
Anthropic, OpenAI, Google Gemini, Grok — or none. Set a primary and a backup for when the first one is down. On every tier, including free.
Or run it entirely on your device
Private Mode answers from your records without anything being transmitted. Ask about public things and only an anonymous search leaves — never your contacts, names or details.
And it works with no signal
On a plane or underground, Private Mode picks up automatically and you can still ask about the people you know. It is the resilient path, not a degraded one.
Privacy by architecture
Most contact products aggregate your data. This one is built so we can’t.
Data minimisation here is structural, not a promise in a policy. And we are deliberate about the claims we do not make — that precision is the point.
What is true
- Your records live in an encrypted store on your device, not in a readable pile on our servers.
- In Private Mode nothing is transmitted at all — the reasoning runs on your device. Ask about something public and only an anonymous search leaves, never your contacts, names or details.
- If you choose a cloud provider instead, you choose which one — and identities are tokenised and phone, email and address redacted before anything is sent.
- Sharing is per attribute and consent-gated — you grant specific fields to a specific person, and it travels as ciphertext we cannot read.
- A grant is revocable, and what you share cannot flow onward to anyone you never authorised.
- We do not sell or share your information with anyone, ever. There is no ad model here.
What we do not claim
- Not “your data never leaves your device,” flat. That is true in Private Mode and not true if you pick a cloud provider. We would rather tell you which is which than use the flattering version of the sentence.
- Not that Private Mode matches a big cloud model at everything. It is better on your own records — it reads the phone numbers and addresses the cloud path redacts — and weaker at open-world reasoning. The app says so when it matters.
- Not that we have solved privacy. We have narrowed what we can see, and we describe the narrow paths plainly.
- Not a claim we can’t evidence. If you find us overclaiming anywhere, tell us and we will correct it.
That second column is unusual on a marketing page, and it is there on purpose: a narrower claim you can check beats a broad one you can’t. The full detail is in our privacy policy — and we are a founding signatory of the HumanTerms privacy pledge.
Getting started
Two seconds at a time is the whole commitment
There is no import to sit through and no database to set up. It gets useful on the first detail you write down.
-
Jot the detail when you hear it
Gluten-free. Dog is called Biscuit. Mentioned wanting that book. Two seconds, attached to the person it is about.
-
Share your own side
Send someone the fields you choose. They send theirs back. Now neither of you will ever have a wrong number for the other.
-
Ask it anything, later
Months later, when you need the detail and would otherwise have blanked, it is there — in plain English, in one tap.

Questions
The things people ask first
What is Deeta, in one sentence?
A private, structured place for everything you know about the people in your life — searchable in plain English, and kept current by the people it is about rather than by you.
How is this different from my contacts app, or from a personal CRM?
Your contacts app stores a name and a number. It has no idea your client is gluten-free or that your friend just changed jobs.
As for personal CRMs: they have all died, and they died for one specific reason — you had to maintain them by hand, so the data rotted faster than you could type. Deeta inverts that. The subject maintains their own record and it stays in sync with everyone they have shared it with, so it gets more accurate over time instead of less.
Isn’t this going to be a lot of typing?
That is the honest question, and it is what has killed every product in this category — people give up because keeping it alive by hand is work.
Two answers. First, your whole address book is already there on day one, synced both ways with your phone, so there is no import to sit through and nothing stranded in a second app. Second, adding a detail takes about two seconds and rarely involves a keyboard: say it out loud, paste a chunk of an email or your notes, share it straight from Messages or any other app, share someone’s digital business card and have it arrive as structured details, or turn an answer you just got into a saved detail. Typing it manually is there too — it is just usually the slowest option.
Someone AirDropped me a contact — does that work?
Yes — you can hand it straight to Deeta. A contact sent by AirDrop, email or message can be opened in Deeta, or shared to it from Mail, Messages or Files, and it arrives as real details — name, title, company, numbers, socials — offered to you as candidates. It goes through the same review step as a shared business card, so nothing is written on its own. A file holding a few contacts is reviewed one at a time. It is built for a card a person hands you, not for a whole address book exported out of another app — that is a different job, and not one Deeta does yet.
The other route still works too, if it is what your hands do first: save the contact in your iPhone’s Contacts app and it appears in Deeta within seconds anyway, because the two stay synced in both directions.
Two honest limits. You confirm before anything is saved — it proposes, it never writes on its own. And a photo attached to the contact file is not carried over; every other field is.
Someone sent me their Blinq card. Can I save that?
Yes, and it comes in as real details rather than a link you will never open again. Share a Blinq, HiHello or Popl card to Deeta and it reads the name, title, company, numbers and socials off it and offers them to you as candidate details. New card services get added without needing an app update.
Three things worth knowing, because they are the honest limits. It fetches and reads the card on your device, at the moment you ask it to — nothing is crawled or harvested server-side. You confirm before anything is saved; it proposes, it never writes on its own. And it takes a snapshot — it keeps the original link alongside, but it does not keep watching their card for changes. If a card is laid out in a way it cannot read, it saves the link and tells you, rather than guessing at a value and getting it wrong.
Where does my data actually live?
In an encrypted store on your own device. We do not keep a central readable pile of relationship data on our servers — there is nothing there to breach or to sell.
We are deliberately precise about the rest. In Private Mode nothing is transmitted to answer a question at all. If you choose a cloud AI provider instead, your question goes to the provider you picked — with identities tokenised and phone, email and address redacted first. Sharing a field with someone transits our servers as ciphertext we cannot read. So we do not say “your data never leaves your device” as a blanket claim: it is true in Private Mode, and not true if you pick a cloud provider, and we would rather tell you which is which.
What is Private Mode?
The AI runs entirely on your device. Your records are never transmitted to answer a question, so there is nothing to intercept and nothing for us to see. Ask about something public — a restaurant, a gift, what is nearby — and only an anonymous web search leaves, never your contacts, names or details.
It is also the offline path: on a plane or underground it picks up automatically and you can still ask about the people you know.
The honest trade-off: on your own records Private Mode is actually better than the cloud, because it reads the phone numbers and addresses the cloud path redacts before sending. On broad open-world questions a big cloud model is stronger, and the app tells you when that is the case so you can switch for that one question. Private Mode needs a recent device with on-device AI support.
Which AI does it use? Can I choose?
You choose — Anthropic, OpenAI, Google Gemini, Grok, or none at all. You set a primary and a backup for when the first is unavailable, and you can change it whenever you like. That is available on every tier, including free.
Most apps in this space hardwire one vendor and never tell you which. We would rather you decided, including deciding that nothing leaves your device at all.
Do you sell or share my information?
No. Not to advertisers, not to data brokers, not to anyone, ever. There is no ad model here and there never will be — the architecture would not support one even if we wanted it, because we cannot read your records.
What does "live" mean — how does something update itself?
Each field on your own profile carries a visibility setting and a version. When you change a field, the new version propagates to the people you have granted that field to. Their copy updates; nobody re-sends a contact card and nobody retypes anything.
It only ever moves in the direction you authorised, and you can revoke a grant at any time.
Can my own AI assistant plug into this?
Not yet — and we are not going to imply otherwise. Letting an external agent query your records on your behalf is on the roadmap, and the architecture is built for it, but it is not something you can use today.
What ships now is the AI inside Deeta: ask in plain English, answered on your device in Private Mode or by the provider you chose.
What does it cost, and what do I get for free?
The free tier is a real product, not a demo. You get everything structural — your whole address book, unlimited details, sharing, Private Mode — and there is no ad model, ever.
What is metered is the expensive part: cloud AI queries and the parsing that turns speech or pasted text into structured details. Free covers a few of each per month. Questions you ask in Private Mode run on your own device, so they cost us nothing and are not counted against that allowance — which is why a lot of people will simply not hit it. Paid tiers raise the limits considerably; prices are not published yet and we would rather say that than post a number we then change.
Which devices does it run on?
iPhone first — that is where the private beta is. iPad and Android are both in development. iPad is largely a layout job on top of the same app, and Android is being built alongside iOS rather than after it, so the feature work is shared rather than repeated.
Join the waitlist for iPhone, or leave your email on the Android page and we will tell you the moment that build is ready.
