GPT GhostWryter vs AIssistify

GPT GhostWryter is a writing assistant add-on that runs inside Google Docs and sends your prompts to OpenAI through your own API key. You highlight text or enter keywords in the sidebar, pick a writing action, and generated copy lands directly in the document. It targets SEO articles, blog posts, essays, and marketing drafts without leaving Docs.

Most AI writers sell monthly word bundles and mark up API costs. GhostWryter charges a small add-on subscription and bills generation through your OpenAI account at token rates. That split keeps the fixed fee low while usage scales with what you actually write, which suits writers who spike output some weeks and go quiet in others.

The sidebar groups tools into idea research, drafting, and refinement. You can generate outlines, expand paragraphs, rewrite sections, list top questions, and run a custom Magic Command on highlighted text. Setup requires matching your GhostWryter signup email to your Google account and saving an OpenAI key in the add-on settings.
