Terms of service

Last updated October 24, 2026.

By using GBK Composer (the website, GBK Studio, and the GBK Composer plugin/MCP server) you agree to these terms.

The service

GBK Composer is a free, experimental music-composition tool provided as is, without warranties. Features, daily usage limits and availability may change, and the service may be paused or discontinued at any time.

Your account

You sign in with Google or GitHub and are responsible for activity under your account. Daily limits on AI usage and renders apply per account; do not try to bypass them or disrupt the service.

Using the plugin without an account

The plugin can create and edit compositions without an account. Each composition is controlled by a private access key returned to the calling app. You are responsible for keeping it; a lost key cannot be recovered, and we cannot move such a composition to an account. Guest use has stricter limits (length, number of edits and requests, shared daily capacity) and may be paused or turned off at any time. Rendered files expire after 30 days. You can delete such a composition yourself with the plugin (the delete tool needs its private key), claim it into an account after signing in, or request deletion through support.

Your content

You keep your rights to the music you create. You grant us the limited permission needed to store, process and display it to provide the service, and, for songs you choose to publish, to show them publicly. Do not publish content you do not have the right to share or that is unlawful or abusive; we may remove such content.

AI output

Compositions are generated with algorithmic tools and an AI model. Output may be imperfect or resemble existing music; review it before relying on it.

Limitation of liability

To the extent permitted by law, we are not liable for indirect or consequential damages or for loss of data. Keep your own copies of important files.
