Reducto Office

Full-fidelity document editing, built for collaboration with AI. Create, edit, and chat with Word documents (DOCX), Excel spreadsheets (XLSX), and PowerPoint presentations (PPTX) — directly inside ChatGPT. Upload an existing file or create a new one to open a live full-fidelity editor alongside your conversation. Make manual edits yourself or ask ChatGPT to make changes—both work in the same document, in real time. From everyday documents to complex layouts and tracked changes, Reducto Office preserves your file’s structure and formatting through editing and export, so you can move seamlessly between contexts. Comprehensive DOCX editing • Write and revise: Draft, rewrite, shorten, or restructure text, with find and replace across the entire document. • Control formatting: Adjust styles, fonts, paragraph spacing, and numbered or bulleted lists. • Work with tables: Insert rows and columns, edit content, and merge cells. • Manage document details: Edit headers, footers, footnotes, endnotes, and comments. • Review changes: Collaborate with redlines and tracked changes, then accept or reject revisions. • Edit rich content: Work with pictures, text boxes, charts, equations, hyperlinks, and form fields or content controls. • See faithful layouts: View pages rendered to closely match their appearance in Word. • Collaborate live in your browser: Work together in the same document with shared cursors and real-time edits, so everyone can see changes as they happen.
