Installation

Install Kismet for Unreal Engine. Run a single command to install it engine-wide, or download the build for your operating system and engine version and install it manually.

Requirements

Before installing, make sure the project meets these requirements.

Unreal Engine5.6, 5.7, or 5.8
Operating systemmacOS or Windows
AccountKismet account
Model accessAnthropic API key

Quick install (recommended)

Run one command in your terminal. The installer finds every Unreal Engine on your machine and installs Kismet engine-wide, under Engine/Plugins/Marketplace, so it is available to all your projects. Quit Unreal Editor before running it.

  1. 1.

    macOS — run in Terminal

    curl -fsSL https://kismetai.io/install.sh | bash
  2. 2.

    Windows — run in PowerShell

    PowerShell will prompt for administrator rights, which Unreal requires to install into the engine.

    irm https://kismetai.io/install.ps1 | iex
To install for a single engine, set KISMET_UE first (e.g. macOS: curl -fsSL https://kismetai.io/install.sh | bash -s -- --ue 5.7). To remove Kismet, re-run with --uninstall (macOS) or $env:KISMET_UNINSTALL='1' (Windows).

Install manually

Prefer to install by hand? Download the build and place it in the engine Marketplace plugins folder so every project on that engine can use it. This is the same location the quick installer uses.

  1. 1.

    Download a packaged build

    Open the download page and choose the archive that matches your operating system and Unreal Engine version.

  2. 2.

    Extract the archive

    The extracted folder should be named KismetAI. Do not rename the folder after extraction.

  3. 3.

    Copy the plugin into the engine Marketplace folder

    Place the KismetAI folder under Engine/Plugins/Marketplace inside your Unreal Engine installation. On macOS this is under "/Users/Shared/Epic Games/UE_5.7"; on Windows it is under "C:\Program Files\Epic Games\UE_5.7".

  4. 4.

    Open Unreal Editor and enable Kismet

    Launch the editor and accept the rebuild prompt if it appears. If Kismet is not already active, enable it under Edit > Plugins, then restart. Kismet then appears in the toolbar for every project on that engine.
