# Understanding Credits

> How the credit system works for creating karaoke

Credits are how you pay for creating karaoke tracks in Youka Online.

## What Are Credits?

Credits are the currency used for AI processing:

* Creating a karaoke costs credits
* Cloud video exports use credits; local exports are free in Desktop and Web + Extension
* Manual editing is free
* Playing from your library is free

## How Many Credits per Karaoke?

A typical karaoke costs **5-10 credits** depending on:

* Song duration (longer = more credits)
* Lyrics mode (transcription costs more than alignment)
* AI model selected (premium models cost more)

You'll see the exact credit cost before creating each karaoke.

## What Uses Credits

| Action                           | Credits Used   |
| -------------------------------- | -------------- |

| Create karaoke (auto-transcribe) | \~7-10 credits |
