Your own AI.
STK turns multiple AI services and chats into one mind — centered around you.
The more you use AI,
the more STK understands you.
How it works
Connect an AI.
It calls STK as it learns you.
The next AI starts from there.
What's kept
And the things you never explicitly said.
The patterns AI discovers along the way.
Every AI learns you. STK keeps it.
Its understanding compounds over time.
Yours to see. Yours to delete. Yours to take.

Questions
Does STK read my conversations?
No. An AI calls STK and writes what it decided to write. STK never sees a conversation, and there is no path from STK back into an AI.
Which AIs work today?
Claude, ChatGPT and Cursor connect over MCP; ChatGPT needs Developer mode turned on. Gemini has no connector yet, which is why its card says Soon.
What happens if I cancel?
A payment covers a month or a year and does not renew by itself, so there is nothing to cancel. Nothing of yours is deleted.
Where is my data?
In one SQLite file on the machine that runs STK. Export hands you all of it. Delete everything removes it, and no copy is kept here.
