CONSULTING ORIGIN
Built from problems we kept seeing on consulting frontlines
Working in consulting across construction, manufacturing, and logistics, we kept running into the same patterns: outsourcing training videos, navigating language barriers, and looping ChatGPT copy-paste sessions. Insight Office Apps is what we designed to handle these in a single Windows desktop app.

AI That Actually Edits Your Files — Securely
Not "ask AI" — "let AI do it." AI directly reads and rewrites your files, with anonymization and send-preview keeping your data safe.

Find and Fix Formula Errors Automatically
AI scans every formula in your workbook, catches calculation errors and broken references, and writes fixes back into cells. It also surfaces anomalies like sudden spikes versus the prior period or values that don't reconcile to last year — before anyone else notices.

Copy Data Between Excel Files Automatically
Drag an existing Excel file onto a collection template. AI reads both files, figures out which columns match which fields, and fills in the values automatically. It only asks for human confirmation where it's unsure. No more manual copy-paste.

Create New Documents from Past Reports
Drag and drop past reports and specs as references. AI learns your writing patterns and drafts new documents. You can also bulk-generate documents from an Excel data list and a template in one go.

AI Reviews and Fixes All Your Slides at Once
Typos, inconsistent wording, structural issues — AI checks every slide and writes corrections directly into your deck without breaking the layout. 30+ built-in check types included, and AI automatically adjusts its processing depth based on the task.
Turn PowerPoint into Training Videos (Multilingual)
Speaker notes become narration with 30+ AI voices to choose from. Generate subtitles with one click, and instantly translate to English, Chinese, or Korean. AI even rewrites bullet-point notes into natural spoken narration scripts.
AI Generates Images and Thumbnails for Your Videos
AI creates scene images and thumbnails right inside your video project. Pick from 11 layout patterns, and AI generates multiple variations for A/B testing. Professional-looking visuals without any design tools.
One App, All Formats — AI Reads Across Everything
Open Word, Excel, and PowerPoint in one window. AI reads your Excel data and drafts a Word report. Review PowerPoint against spec documents. Cross-format intelligence without switching apps — this is Insight Office.
AI You Can Trust in the Workplace
Built from years of consulting practice. AI that operates on the files you already work with — with security designed in from day one.
