Three steps and you're ready
From download to overlay: the essentials so you don't get stuck in config.
Install and open Buildzcrank
Run the installer and launch the app.
Set up League for the overlay
In the League client choose windowed or borderless. Exclusive fullscreen usually blocks panels from appearing above the game.
What you get
Everything on one desktop: live match context, AI to buy smarter, and champ-select without hopping between tabs.
Match
Your state, always visible
HP, gold, summoners, inventory and recent activity without opening the client.
AI

Item rankings with probabilities so you decide the next purchase without guessing.
Champ select
Runes and teams on one screen
Bans, picks and runes together so you load into the game with a clear head.

Frequently asked questions
Short answers on usage, privacy and updates.
Is it free?
Yes. The installer is free; download it with the button on this page.
Is my match data sent over the internet?
NO. The app reads match state from the League client's local API on your machine. The internet connection is mostly used for icons, checking for updates and, if needed, fetching a new app version — not to "process" your match in the cloud.
Do I need to sign in to Buildzcrank?
No. We don't ask for a Riot account inside the app: it uses the data the client exposes locally while you play.
How do I get updates?
Buildzcrank can notify you when a new version is available. The installer is designed for easy updates.
Is there a Mac or Linux version?
Windows only for now.
The overlay doesn't appear?
Enable windowed or borderless mode in League of Legends; exclusive fullscreen usually covers other windows.
Do AI suggestions guarantee a win?
No. They help you decide; you play the game.
Does it modify or inject code into League?
No. It's a separate application that reads local info and displays windows on top of your desktop. If third-party software policies concern you, review the Riot policies that apply to your account.
Is this an official Riot product?
No. Buildzcrank is independent.
