Word Express (GPT4Office)

Word Express is an add-in for Microsoft Word designed to keep AI assistance inside the editor you already write in. Instead of switching to a browser tab, you install the add-in and get a task pane where you can prompt GPT models to draft paragraphs, rewrite awkward sentences, summarize long sections, generate images to illustrate a document, or turn recorded meeting audio into text. The tool also covers speech-to-text and translation, so a recording in one language can be turned into written notes in another.

Because the product is delivered as an Office add-in, its value is mostly workflow: everything happens next to the cursor. The article-wizard style flows are meant for people who have a rough idea and want a structured first draft, while the rewriter and summarizer are for polishing or condensing text you already have. Pricing is advertised as a free trial with paid plans, though the exact tiers and limits should be confirmed on the vendor's current pricing page.

One important caveat: this is a third-party integration. It is not developed, endorsed or operated by Microsoft or OpenAI, and because the domain has previously presented SSL certificate mismatches, users should verify the legitimate installation link before entering credentials.
