Users can also install Kai in RAD Studio 12.x, Delphi 12.x, and C++Builder 12.x (32-bit IDE only), except for the Community Editions.
Using the GetIt package manager, search for Kai and click Install.
Another option is to download Kai from the Embarcadero customer portal with an active EDN account.

Installed CLIs
The following CLI local LLMs interfaces are preinstalled with Kai. These tools are installed in the main Kai folder by default.

Claude Integration
If you wish to integrate Claude Code as an LLM interface, you first need to have npm installed to install the Claude Agent ACP. The next step would be to install Claude Code. Note that the Claude Agent is not the same as the Claude desktop app. You need to install the Claude Agent even if you have previously installed Claude Desktop.
Claude Code cannot be legally distributed by a third-party installer.
Follow the steps below to integrate Claude Code:
1. Close RAD Studio if it is open.
2. Download the Node.js LTS installer.
3. Install Node.js; this also installs npm.
4. Open a terminal to use npm, and run:
Npm install -g @agentclientprotocol/claude-agent-acp
5. Install Claude Code from PowerShell and add it to the path as needed, for example:
Irm http://claude.ai/install.ps1 | iex
6. Now, from the terminal window, run the following Claude command:
claude
7. A prompt pops up asking users to log in to Claude. Follow the instructions and, in the browser window, log in to your Claude account. Once logged in, return to the terminal window.
At this point, the installation is complete, but it is necessary to ensure that Claude tools are visible in RAD Studio. This can be done by checking the path environment variable.
8. Click the Windows key and search for "envir". Select the Edit the system environment variables option.
9. When the System Properties window opens, ensure you are in the Advanced tab and click the Environment Variables option.
10. In the Environment Variables window, select the Path variable and click the Edit button.
11. In the dialog box that appears, click on the New button.
12. Next, edit the new blank entry by typing:
%USERPROFILE%\.local\bin
13. Click Ok and close the Environment variable window.
14. Now, when you go into RAD Studio, you will be able to select Claude as one of the options in the Kai Chat window.
When navigating in the Tools > Options > Kai settings, Claude Code cannot detect if you are logged in; thus, the Kai settings configuration window displays a message requesting users to log in. This is static and does not reflect the real status.
