Text answers work immediately — nothing to configure. You only need this
step before anyone attaches a file or video to an entry, because OpenJanela has to be
told where on the server to keep those files.

Setting the KB files directory

1. Open Administration and Setup → Company Preferences.
2. Choose the AI Assistant tab.
3. In the Branding & Files panel, fill in KB files directory.
4. Click Save. You should see “AI assistant settings saved.”

Two things the folder needs:

• Writable by the account the application server runs under. OpenJanela creates the
  folder and its sub-folders on the first upload; if it cannot, the upload fails.
• Included in your backups. Only a reference to each file is stored in the
  database — the file itself lives in this folder. Backing up the database alone will
  not bring your attachments back.

Inside it, OpenJanela files uploads per company as
<your directory>/kb/<company id>/, under generated names. Leave that
structure alone; the entry’s original file name is remembered separately and is what staff
see.

The rest of the AI Assistant tab

The same tab carries the assistant’s own settings. You do not need them for a text-only
Knowledge Base, but they are what makes the assistant able to answer from it:

• Enabled, Provider, Model, Base URL, API key —
  the assistant itself. Max tokens and Temperature tune reply length and how
  literal the replies are.
• Instruction — standing instructions for the assistant. Leave blank for the
  built-in default.
• Assistant name and Logo — branding shown in the chat window.
• Vision settings — used only where images are read.
