An AI that reads your email, your calendar, and your meeting notes, and runs entirely on your phone. It briefs you every morning, catches every dropped ball, and gives you superhuman memory. Nothing leaves the device.
By invitation. Limited early access.
On-device foundation models. Koretex runs entirely on the silicon already in your pocket, no cloud roundtrip, no third-party API, no exception.
Recommended on iPhone 15 Pro and later. Android release rolling out by waitlist. The deep index builds overnight while your phone charges.
Koretex was built on a single architectural decision: nothing leaves the device. Your email, your calendar, your meetings, your commitments, all read, indexed, and remembered on your phone and nowhere else.
There is no server to breach. No cloud to subpoena. No brief to leak.
Privacy is not a setting. It is the foundation.
Every morning at seven: today’s meetings with the history behind them, the replies you owe, the promises coming due, and the people who have gone quiet on you.
Walk into every room knowing exactly who you are meeting, what you discussed last time, and what you said you would do about it.
The thread you opened and never answered. The deck you promised on Friday. The introduction you said you would make three weeks ago. Koretex reads what you owe and surfaces it before anyone has to chase you.
Each one arrives with a draft already written, in your voice, referencing what was actually said.
Ask it anything across everything: “What did I promise Lena?” “Who did I meet in Singapore who was raising for climate?”
Every email, meeting, and note is filed to the person it belongs to. Relationships, not threads.
Follow-ups written from your actual history with each person, ready to edit and send.
Every other assistant goes silent the moment you disconnect, because your life lives on their servers. Koretex gets sharper, because everything it knows is already in your hand.
An AI that knows your whole working life, demonstrably offline. That is the test. We invite you to run it daily.
Every other AI assistant treats your email and calendar as a stream of data to be uploaded, processed, and stored on their servers. Koretex was built so that none of that happens.

Vendor practices summarized from public documentation, as of 2026. Cloud assistants process and store your content on their infrastructure or that of their model providers. Koretex reads locally, indexes locally, and stores your memory only on your phone.
And anyone else whose working life cannot be entrusted to a third party.
Koretex is rolling out by invitation. Request a seat and your chief of staff starts reading the moment you are in.
