SAN FRANCISCO – October 30, 2026 -- Reducto has released Reducto Office, a free plugin that lets AI agents edit existing DOCX, PPTX and XLSX files inside ChatGPT and Codex. The plugin is available now, with usage limits.

Users install the plugin, connect a Reducto account and bring their own files into an AI conversation. Agents apply targeted changes, which appear in a live editor where users can review and refine them.

Headless document engine lets agents edit structured files directly

Office runs on a document engine that agents operate headlessly, rather than through a graphical interface built for people. Reducto says reliable editing has to preserve structure: nested tables, reviewer comments and tracked changes in contracts, and slide layouts, fonts and charts in presentations. Output stays in standard Word, PowerPoint and Excel formats that users can keep editing and share.

Legal, finance and consulting teams get three defined workflows

Reducto lists three use cases:

• Legal teams work through reviewer comments in a contract, have an agent propose revisions as tracked changes, and decide which to accept or reject.
• Finance and operations teams turn a budget or project brief into an editable Excel workbook, then refine it with an agent.
• Consultants, sales and marketing teams translate a client presentation for a new audience while keeping its slide layouts and design.

Separate licensed Reducto Editor targets developers building their own products

Reducto Editor is a distinct offering for developers and product teams embedding editing into their applications. It provides a licensed, embeddable UI and SDK for DOCX, PPTX and XLSX. Office extends Reducto's editing technology to end users through ChatGPT and Codex, following the company's earlier work on making complex documents understandable to AI.
