A companion that remembers.
Semantix Companion is a desktop app where every companion keeps a private mind. What you say becomes memory. The memory becomes a sky you can ask.
A companion named Studio, asked one question. 2,390 memories, 7,163 links, one bolt to the answer.
The memory sky
Every memory is a star.
A companion’s memory is drawn as a sky: one star per memory, one line per link. Type a question, and lightning runs to the answer.
Each kind of memory keeps its own tint, so the sky reads as one spell.

Private minds
One mind per companion.
Each companion keeps its own memory and searches only its own past. Two companions can sit in the same app and never share a thought.
When it recalls something, it shows you what it found, right on the message that triggered it.
Tools in the open
Watch it work.
When a companion searches the web, reads a page, or writes a file, each call appears as a glass pill: what it did, how long it took, whether it worked.
Nothing happens behind a curtain. There is no curtain.
What it is
Built to be lived with.
A desktop app
Rust and React, running on your machine. Your conversations stay in your private workspace.
Your models
Run a companion on Claude Code, or on any OpenAI-compatible endpoint you point it at.
It sleeps, too
When a conversation is ripe, the companion distils it into memory on its own. We call it the sleeper.
They call each other
Companions can open a call or send mail to one another, and you can read every word.
