A custom assistant. A shared brain.
A WhatsApp assistant and a small brain on your own server, made for one family or one close group of friends. Joins one chat, holds the things everyone keeps half-forgetting.
Self-hosted. Consent-first. Nothing posts to your group without a human tap. Built by hand from Barcelona.
One chat. One quiet helper underneath.
Six tiny scenes
Two weeks ago over lunch the family agreed something specific about the summer rental — the dates, the deposit, who's bringing whom. Now nobody can remember the detail.
"Kazimir, what did we say at Sunday lunch about the Mallorca place?" — ten seconds, you have it.
Tuesday morning, Grandma is in the chat asking — a bit confused — who's collecting Leo today. Three messages from last week have the answer, buried under a hundred others.
Kazimir replies in the group within seconds: "Today Marc — Anna and Lou have swim class. Anna wrote it on Sunday."
Every Friday someone says "we need olive oil, lemons, that detergent". Half of it is in voice notes. Nothing makes it to a list.
Kazimir keeps a running list, all week, from whatever anyone mentions. Saturday morning it offers it back: "this is everything that came up — anything missing?"
Five friends have been trying to meet for two months. Threads die on Thursday, revive on Monday, die again on Wednesday. Nobody is to blame — calendars are calendars.
You tell Kazimir "make this happen". It runs a quiet poll, picks the time five out of five can do, and books the restaurant you've all said you wanted to try.
Over a year you've all recommended each other films, books, restaurants, that bar in Athens, the hike outside Lisbon. None of you remember any of them when you actually need one.
"Kazimir, what was that Portuguese film Ana said I'd love?" — answer, with the date she said it and a link.
Five separate threads about the same trip. Three Google docs nobody updates. A flight nobody booked because it wasn't quite settled.
Kazimir keeps one summary, updated as things change, and DMs each of you the relevant bit when you need to act. The trip happens.
A real feature, not a demo
Commit — for the dinner that won't book itself.
You need to find a time. Five friends. Or a family of seven across two cities. Or three people and a babysitter.
Tell Kazimir who, when, and how long. It sends a small private poll to each person — in their own WhatsApp, no group spam — and waits.
Some people are key — the time has to work for them, full stop. Others are flexible. The brain weighs the votes, applies a quorum rule, and picks the time that maximises real attendance.
Then it tells you. You confirm. The booking goes out.
Consent as a design feature
Before Kazimir writes a single line, everyone in the group reads and agrees to a one-page document in plain language. Privacy isn't a footnote — it's the opening ceremony of the product.
One page. No legalese. Everyone in the chat sees this on day one.
Nothing without a human tap
Kazimir never posts to the group by itself. Every message it wants to send goes through a person first — usually whoever set it up, but you can share that role.
Every group message goes through a human tap first.
The chat asks a question. A reminder comes due. A thread needs a reply.
It writes a short message privately — to you, not to the group.
You approve, edit, or discard. Two seconds on your phone.
The message appears in the group. Everyone can see it came from Kazimir.
Where it lives
One house. One notebook. No visitors.
The assistant your group talks to in WhatsApp is called Kazimir. The same assistant in Telegram is called Stepan. Both run on the same reasoning brain — installed on your server — that actually remembers and connects dots. We sell them as one product, install them as one product, and hand the whole stack over to your group on day one.
One price, one monthly
Simpler than the solo version — one group instead of a full life. A flat setup, then a small monthly for the box and the care.
The awkward ones, answered plainly
It would be, if it were secret. The whole design is built around the opposite: everyone in the group knows Kazimir is there, everyone reads the charter on day one, everyone can read what it remembers at any time, and everyone can ask it to forget. It's a helper in the room, not a listener behind a curtain.
Yes, carefully. If anyone in the group is under 16 we adjust the charter: shorter memory, stricter deletion, and Kazimir doesn't initiate messages with them. A 12-year-old can ask "what time is football?" and get an answer. A 12-year-old won't be drafted to in private.
Within 24 hours, everything Kazimir remembers about that person — their messages, the facts it inferred, their preferences — is wiped from the server. The rest of the group keeps functioning; they just lose the things only that person contributed.
No. It's been tuned hard against that. If the group is arguing, Kazimir goes quiet until asked something specific. It never volunteers opinions about people, never summarises a fight, never reminds anyone of something said in anger.
Yes. Together works for any small circle of close people — old friends, a band, a book club, a co-parenting arrangement, a small shared household. The one rule is that the people in the group actually know and trust each other.
I walk everyone through what Kazimir does, answer all the questions, and we decide together. No pressure, no pitch. If it's not right for your people, I'll say so first.
