Ghostreader

How do I enable auto-summarization or auto-tagging?

To use the customized Ghostreader prompt, you'll need to first make sure that auto-summarization or auto-tagging is on in the Integrations settings under the OpenAI options.

Why are items in my Feed not auto-summarized?

By default, Ghostreader will only automatically summarize documents that you manually save to your account using the browser extension, mobile app share sheet, and so on. Documents in your Feed will not be summarized unless you invoke Ghostreader manually.

You can, however, enable auto-summarization on Feed documents by adding your own OpenAI API key. Once you add your key, your Feed documents will start being automatically summarized and will use your API credits.

How can I use a different GPT model, like GPT-4o?

The default AI model (included with your Readwise subscription) is GPT-4o Mini. However, if you've entered your own OpenAI API key, you can change the AI model on any custom Ghostreader prompts to GPT-4, GPT-4 Turbo, or GPT-4o. You can find the AI model dropdown in the bottom left corner:

Do I need an OpenAI API key to enable auto-summarization of documents?

No. Auto-summarization of documents saved to your library is included as part of your Readwise subscription. However, if you would like to enable auto-summarization of feed documents or use a better AI model than GPT-4o Mini, you will need to add your own key.

What happens if I add my own OpenAI API key?

If you have your OpenAI key set up in the integration settings, it will automatically summarize all the docs coming into your feed (newsletters, RSS subscriptions, etc) in addition to the automatic summarizing of documents saved to your library.

By default, the auto-summarization of library items will use GPT-4o Mini and will not use your OpenAI key. To change this, you can set the model per prompt on the Ghostreader customization page. If you choose a higher-tier model, it will then use your OpenAI key.

Why am I getting an error that says "Chosen prompt model is not available"?

This error message generally appears when the OpenAI API key associated with your account doesn't have enough funds to cover the request. If you log into OpenAI's website and check your billing details, you should be able to see your usage and plan limits there.

If your API key isn't funded, you can switch your Ghostreader model to GPT-4o Mini or GPT-3.5 Turbo, both of which are included with your Reader subscription, or you can fund the OpenAI API key on their end.
