GhostWryter

The interesting thing about GhostWryter is what it refuses to be. It is not another all-in-one AI editor with a credits meter and a dozen template galleries — it is an add-on that puts a prompt box in the Google Docs side panel and inserts the result into the document you are already editing. For people whose entire content operation lives in Docs, that removal of a copy-paste step is the whole product, and it is worth more than it sounds when you are producing twenty articles a month. The pricing model is the second thing that sets it apart, and also the thing you must read carefully. Generation is billed at OpenAI's token rate against your own API key: the vendor states $0.02 per 1,000 tokens on the Davinci model, and 1,000 tokens is roughly 750 words, so about $1 buys 37,500 words. GhostWryter puts no markup on that. On top of it sits a $2.99/month subscription that unlocks content-idea generation, rephrasing of existing text, and writing-tone adjustment. The catch worth knowing before you commit: the vendor's subscription page says subscribers who never cancel stay at $2.99/mo permanently, but if you cancel once and come back, the rate becomes $7.99/mo. That is a genuine loyalty discount rather than a promotional price, and it cuts the other way — churn is penalised. Strengths: genuinely low content cost at volume, no vendor-side credits to run out, output goes straight into the doc, and the subscription layer is cheap enough to be an afterthought. The Davinci-era framing on the vendor's own pages is the weak point; if you care about which model is doing the writing, confirm current model support with the vendor before committing, because the marketing copy names only Davinci. The other hard constraint is structural: no OpenAI key, no text. Your spend lands on your OpenAI account rather than a single GhostWryter invoice, which some finance teams will dislike. And as an add-on there is no standalone web app, no mobile app, and no team seat management — it is a personal productivity tool, not a content platform. Where it fits: solo bloggers, freelance writers, and small marketing teams already holding an OpenAI key who want cheap volume inside Docs. Where it doesn't: agencies needing roles and approvals, teams that want one consolidated bill, or anyone who would rather not touch an API console.
