Ask anything. Give away nothing.
The AI that doesn’tbuild a profileon you.
Research, write, plan and make sense of long documents with the strongest AI there is. Your name, your private details and even your internet connection stay out of it — so nothing you ask can be turned into ads, tracked across the web, or sold on.
- Your connection stays hidden
- No ads, no tracking
- Nothing about you sold
- Your memory is yours
KelvenCompare these two business ideas and tell me which one has better economics.
- Understanding task
- Retrieving relevant context
- Selecting intelligence
- Generating answer
The subscription idea has the stronger economics. It compounds: each customer keeps paying while acquisition cost stays fixed, so margin improves over time.
- · Recurring revenue instead of one-off transactions
- · Roughly 3x higher gross margin at the same volume
- · The marketplace idea only works with heavy supply investment first
If speed to first revenue matters more than long-term margin, the marketplace is the shorter path — but it plateaus.
Why people want this
Four things nobody likes about using AI right now.
None of them are your fault, and none of them need to be the price of a good answer.
The quiet profile
Everything you ask becomes a picture of you
Health worries, money trouble, family questions, a job you're thinking about leaving. Typed into most AI, those become a record tied to you — useful for targeting ads at you, and valuable to whoever will pay for it.
Kelven takes your name and personal details out on your own device first, so the questions can't be built into a picture of you.
Being followed around
Your connection leaves a signature on every question
Even with no name and no account, your internet connection carries a number that stays the same all day. It is how the same ad follows you from one site to the next after a single search.
Kelven asks on your behalf, so the AI company sees Kelven's connection instead of yours — not your home, your office, or your area.
Work you can't paste
The things you most need help with are the things you can't share
A client contract. Your real numbers. A difficult message about a real person. So you either water it down until the answer is useless, or paste it and hope.
Kelven swaps the real names and figures for stand-ins before sending, then puts the real ones back in the answer on your screen.
Starting from zero
Explaining yourself again, every single time
Who you are, what you do, how you write, what you're working on. Re-typed into every new conversation, and stuck inside one company's app when it is saved at all.
Kelven remembers it and shows you exactly what it kept. You can change it, delete it, or keep it only on your device.
In plain words
Your connection is a return address.
Yours stays off the envelope.
Every time your device sends something out, it includes a number so the reply knows where to come back to. You never see it, but it barely changes from one hour to the next.
Companies that build profiles for advertising treat that number like a signature. It is how a private question you asked in one place turns into an ad somewhere else, and how a rough idea of your city and neighbourhood gets attached to what you asked.
When you ask Kelven something, Kelven does the asking. The AI company answers Kelven — it never receives your connection, so there is no signature of yours to match anything to.
Without Kelven
You → the AI company. Your question, your name in it, and your connection all arrive together, and can be kept together.
With Kelven
You → Kelven → the AI company. The personal parts are removed on your device, and the request arrives from Kelven, from a connection that is not yours.
Kelven never keeps a readable copy of your connection either — for signed-out use it is turned into a short scrambled code that cannot be turned back, only used to stop abuse.
Three steps
Nothing to set up. Nothing to remember to turn on.
- 01
Ask normally
Type it the way you'd say it to a person who already knows your situation. Real names, real numbers, a file if you have one.
- 02
Your details stay home
On your own device, the personal parts are taken out and stood in for, and the asking is done for you so your connection never goes out.
- 03
You get the real answer
The strongest AI available does the thinking, and your real names and numbers are put back in on your screen. Only you ever see the complete version.
Being honest about the limits: no check catches everything, and an outside AI company still reads the stood-in version of your request in order to answer it. Kelven shows you what was sent, and passwords and codes are removed rather than put back.
What you can bring it
Bring Kelven the work. Get something usable back.
Ask a question, drop in a file, or just say what you need. It takes it from there.
Ask
A straight answer, without picking anything first.

It remembers
Stop explaining yourself in every new conversation.
Your preferences, projects, decisions, and working style can carry from one task to the next, so Kelven becomes more useful without making you repeat the basics.
You can see what is remembered, change it, remove it, or keep it only on your device. Your context stays with you even when the best available AI changes.
One memory. Always yours.
Models change. Interfaces change. Your context stays with you.
What Kelven memory can contain
- Your preferences
- Your projects
- Your decisions
- Your working style
- Your recurring instructions
- Your important relationships and context
- Your privacy preferences
Kept intentionally, not collected exhaustively. You can see every item, edit it, delete it, and decide whether it may ever be shared outside Kelven.
The short version
Real help with real work, without giving yourself away.
No ads built from you
Nothing about you is sold, and nothing you ask becomes material for targeting you later.
The best AI, not a safe one
Keeping something private never means a weaker answer — the strongest models still do the hard part.
One place instead of three
One subscription covers research, writing, long documents, planning and code.
It knows you
Your way of working carries from one task to the next, and it is yours to read, change or delete.
