Set up your Anthropic API key

Set up an Anthropic API key within the add-on settings to use Claude models in GPT for Docs. You can register both an Anthropic key and an OpenAI key to benefit from a wider range of models.

  1. Create a Google document or open a document that you own.

  2. Select Extensions > GPT for Sheets and Docs > Set API keys.


    If you get an error, it means you are likely using multiple Google accounts in the same Chrome session. To fix this, create a dedicated Chrome profile, then create a new spreadsheet and set up your Anthropic key in this new spreadsheet.

    If the problem persists, please let us know by submitting a support request so we can assist you further.
