OpenAI API Compatible
Connect to other AI vendors that are compatible with the OpenAI API standard.
To prevent overwhelm, Novelcrafter officially offers support for a small number of AI vendors. However, you’re not limited to just those. Many other vendors follow a widely used connection standard (known as “OpenAI Compatible API”), and Novelcrafter can work with them too.
To check whether your vendor is compatible, look for a mention of “OpenAI Compatible” on their website or documentation. These usually end with /v1 in their BaseURL. Check out our list below of vendors that have been tested and verified to work with Novelcrafter.
How to Set Up
Open your AI connection settings,
At the bottom of the list is an option for the “OpenAI Compatible Connection”. Click add
Enter the base URL of your vendor’s OpenAI Compatible endpoint, and your API key.
In most cases, Novelcrafter will automatically detect which AI models your vendor offers. If that doesn’t happen, switch to “Use custom model list” and type the model names yourself, separated by commas or line breaks. Be careful to spell each name exactly as your vendor lists it, as Novelcrafter does not check for typos.

Unsupported Vendors
Even though some vendors offer OpenAI SDK compatability, they are incompatible with Novelcrafter.
Anthropic / Claude Console
Anthropic has an OpenAI SDK compatible endpoint that cannot be reached from your browser. As such, you need to set up an in-between proxy if you want to use it:
- Managed: You can use OpenRouter’s BYOK (Bring Your Own Key) service to connect to Anthropic.
- Manual set up: Use a self-hosted service like LiteLLM.
