Optero

Optero is an AI-powered document automation tool for Google Workspace and Microsoft 365 that reads your actual Sheets, Docs, Slides, Excel, Word, or PowerPoint files, uses AI to generate a precise execution plan of edits (formulas, formatting, text changes and more), shows a side-by-side diff for explicit approval, then applies the approved changes through official APIs with full snapshots and one-click rollback; it’s designed to save hours on large cleanups, financial closes, reporting and data standardization by letting AI handle the reasoning and bulk edits while you retain control, auditability, and enterprise-grade security with files staying in your cloud.
