GhostWryter

GhostWryter is an AI writing assistant built as an add-on for Google Docs rather than a standalone app or website. It gives users a set of prompts and functions inside Docs to draft and edit SEO text, blog posts, and other marketing content using OpenAI's GPT models. It is aimed at SEO managers, editors, bloggers, marketers, and students who already write in Google Docs and want AI assistance without leaving that workflow. The tool requires users to supply their own OpenAI API license key and sign up for GhostWryter using the same email address associated with their Google account. Costs work on a pay-per-use basis tied to token consumption: the site cites roughly $0.02 per 1,000 tokens, about 750 words, when using OpenAI's Davinci model, meaning around 37,500 words can be generated for about one dollar in API costs, separate from GhostWryter's own subscription fee of $2.99 per month. Because content generation happens through the user's own OpenAI account, GhostWryter's role is mainly the interface and the prompt library rather than the underlying language model. The site is distributed through the Google Workspace Marketplace. It does not state a founding year or a company name distinct from the product, and no other integrations or a public API beyond OpenAI are mentioned.
