Harvard · early access

Everyone you meet here, you will meet again.

Sections, labs, clubs, conferences, reunions — more people in a month than most people meet in a year, and by next week the names are gone. Deeta is the private cheat sheet for all of them, so you never have to do the "heyyy… you" again.

From a team affiliated with the Harvard Innovation Labs. Any harvard.edu or hbs.edu email address gets 30 days of Deeta Pro, free — alumni included.

How a Deeta record stays current Sharing runs in both directions. When you change a detail on your own profile it updates on the side of anyone you have shared it with, and when they change theirs it updates on yours — neither of you re-sends anything. Separately, you can ask questions in plain language, answered on your own device in Private Mode or by the AI provider you chose. YOU → THEM THEM → YOU YOUR SIDE You mobile role prefers SOMEONE YOU KNOW Their side mobile wish list prefers ASK IN PLAIN ENGLISH Private Mode · on-device NOTHING TRANSMITTED

Students, faculty, alumni

Density is the whole point

Harvard is the rare place where almost everybody you meet, you will meet again — next term, next conference, or at a reunion fifteen years out. That is exactly where remembering compounds.

Names, fields, where you met

Two words as they walk away is enough, and you can just say it into your phone: "Chan School, epidemiology, rows." You will not be caught out in October.

Better when your circle is on it

Swap profiles and nobody has a wrong number for anybody — a section, a lab, a club, a department, a class committee.

It still holds fifteen years out

The classmate who becomes a co-founder, the postdoc who ends up running a fund. A network only pays off if the record survives the decade — and this one is kept current by the people in it.

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.
Ways a detail gets into Deeta Your phone's whole address book is already there. On top of that you can speak a detail, type or paste one, save something straight from Messages or any other app, share someone's digital business card link, hand over a contact file someone AirDropped you, or turn an answer from a question into a saved detail. IT GETS IN HOWEVER SUITS YOU speak it type or paste share from any app their Blinq card a contact file from an answer ALREADY THERE Your contacts SYNCED BOTH WAYS

Two seconds per detailNo import to sit through

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.

Questions

Harvard questions

Who counts as Harvard here?

Anyone with a Harvard email address — undergraduates, graduate and professional students, Extension School students, faculty and staff, and alumni. Any harvard.edu or hbs.edu email address works, including the school subdomains like college.harvard.edu and hls.harvard.edu.

If you have an email address that you think should qualify and does not, tell us and we will look at it.

How do I get the 30 days of Deeta Pro?

Verify your Harvard email address inside the app and the 30 days of Pro is applied to your account. The offer is for the Harvard launch specifically.

Are you affiliated with Harvard?

The team is affiliated with the Harvard Innovation Labs. That is an affiliation, not a partnership or an endorsement by the University — we would rather state it precisely than let it read as more than it is.

Is it free after the 30 days?

There is a free tier that stays free and is genuinely useful on its own. Pro is the paid tier; after the 30 days you simply drop back to free unless you choose otherwise.

Can people outside Harvard use it?

Yes — anyone can join the general waitlist. The Harvard verification only affects the 30-day Pro offer, nothing about the product itself.
