Semantix Companion

Creating a companion

Four fields, three of them optional — and it exists from then on, with a memory of its own.

Settings → Companions → Add companion.

The form is deliberately short. Only one thing in it is required, and it is not the name.

The fields#

Name — optional, up to 80 characters. The placeholder tells you so: Leave blank to keep this companion unnamed. An unnamed companion appears everywhere as Unnamed companion and works exactly like any other. Naming is for you, not for it.

Model — which model answers when you talk to this one. It starts on Default, meaning it follows whatever you set as your default model, and the option shows you what that currently resolves to. Give it a model of its own and it stops following. Two lanes are on offer: the Claude models, and any model you have configured on Together AI or OpenRouter.

Connecting a provider

Style — optional, a voice from your style library. The default is No style — speaks plainly. Pick one and this companion talks in that voice. Each option shows how many example exchanges it carries.

Styles

Workspace access — the folders this companion may work in. Empty by default, and that is a real default, not a placeholder.

Then Add companion at the bottom. That is the whole ceremony.

Note

The form tells you what you are getting before you commit to it: A new companion starts with an empty memory of its own.

Workspace access, in detail#

This section is worth its own explanation, because it is the only place in the app where you hand a companion reach into your machine.

With no folders, the section reads No workspace access — file tools stay hidden until a folder is added. That is literal. The companion has no file tools at all; there is nothing to permit, because there is nothing there.

Click + Add folder and pick a real directory. You get a row with two parts:

  • A folder name, required, up to 80 characters, and unique among that companion's folders. It is filled in for you from the folder's own name, and you can change it to whatever you would rather call it. This name is how the companion refers to the place.
  • The folder itself, shown as its full path.

Rows can be reordered with and , pointed somewhere else with Change, or dropped with Remove. The same folder cannot be added twice to one companion, and a folder that does not exist is refused when you save.

Editing one#

The pencil on any row reopens the same form, filled in, headed Edit companion, with Save changes at the bottom.

The subtitle changes to answer the question everyone has at that moment: Renaming a companion leaves its memory exactly where it is. A companion is not identified by its name, so changing it costs nothing.

Deleting one#

The trash icon asks first. It turns into Cancel and Delete, and only the second click removes the companion.

Warning

Deleting a companion is not a rename. Its memory is its own, and it goes with it.

The built-in companion has no delete button. The app ships with one companion and will not let you remove it, so there is always somebody to talk to. You can rename it, give it a model, a style and folders like any other.

What each row tells you#

The companion list is a summary of everything above. A row shows the companion's name, which model answers for it, its style if it has one, and a small chip reading Private memory — or Private memory · 📁 followed by its folders, when it has been given any. The built-in one is marked · Built-in.

There is also a history button on each row — Bring your history — import old Claude or ChatGPT chats — which is how a new companion starts out already knowing you.
