CoreGPT

CoreGPT adds an AI sidebar directly inside Word, Excel, PowerPoint, Outlook and OneNote, and the equivalent Google Workspace apps, so a user never has to copy and paste between a chatbot and their document. It writes drafts, builds spreadsheet formulas, creates slides and drafts emails from inside the app itself.

In Word it can draft a document section from a short instruction and insert it directly; in Excel it can write and apply a formula such as an IF statement across a column from a plain-language request; in PowerPoint it helps build a pitch deck's slides.

CoreGPT runs on more than one underlying AI model, including Claude Sonnet, and is rated 4.9 from more than 680 store ratings. It is free to start with no credit card, then sold as one shared credit pool per suite (Microsoft 365 or Google Workspace) rather than a separate plan per app.

Use cases

• Drafting a project proposal directly inside a Word document
• Building a spreadsheet formula without writing it by hand
• Creating pitch deck slides inside PowerPoint
