Support

Write to support@biermann.dev. It helps to include the version of Kohera (menu “Kohera” › “About Kohera”), the version of macOS and what you did before the problem occurred. Do not send API keys.

Frequently asked questions

Do I need an account with an AI provider?

No. On Macs with Apple Intelligence, Kohera works with the model on the device, without a key and without a network connection. Large models are more accurate; to use one, add a provider and your own API key in Settings under “Models”.

Where are my texts stored?

In the project file (.novel), wherever you save it. Kohera uploads nothing to a server of the developer.

What is sent to an AI provider?

The scenes or chapters you have Kohera analyse, the project’s world knowledge (entries and statements) and your “Instructions for the AI”. Nothing is sent until you have given the provider permission in Settings.

How do I withdraw the permission?

In Settings under “Models”, select the provider and turn off “Send text to this provider”.

What can I import and export?

You can import .txt, .md and .docx. You can export the manuscript as .docx and the review report as Markdown.

Which languages is Kohera available in?

The interface is available in German, English, French, Spanish and Italian. Kohera works on manuscripts in 28 languages.

Where can I find all tools and shortcuts?

In the “Help” menu under “Tools and Shortcuts” (⌘/).

Which version of macOS do I need?

macOS 26 or later.
